Where Harvest Performance Begins: Inside the Cleaning Star Gearbox<\/h2>\n

\"CajasSugar beet harvesting is one of the most mechanically punishing operations in British agriculture. Every October through January, machines working across the fens of Cambridgeshire, the silts of South Lincolnshire, and the chalk wolds of the East Riding face an unrelenting demand: separate hundreds of tonnes of fresh beet from wet soil, embedded stones, and leaf residue without damaging the crop or breaking the machine. At the mechanical centre of that cleaning process sits the cleaning star gearbox \u2014 a component that rarely earns headlines, but without which no modern beet harvester functions. This precision agricultural gearbox transfers rotational power from the main PTO input to the cleaning star shafts, driving the star-wheel assemblies that tumble beets across the cleaning section at carefully controlled speeds, knocking loose soil through the gaps while advancing the cleaned crop toward the elevator. A gearbox that delivers the wrong output speed, develops excessive backlash after the first season’s use, or fails catastrophically when a stone enters the cleaning section is not an inconvenience \u2014 it is the end of the harvest window for every farm in that contractor’s schedule. At Ever Power, we have been building agricultural gearboxes for close to three decades, and in that time we have learned precisely what the cleaning star application demands: robust materials science, meticulous sealing, and engineering tolerances that hold up when the conditions are at their worst.<\/p>\n

The cleaning star gearbox is not interchangeable with a generic agricultural drive unit. Unlike gearboxes used in manure spreaders or mowers, this component operates under constant, variable-magnitude shock loading as beets strike the star elements, combined with a permanent contamination threat from fine silt, clay-laden water, and mildly corrosive sugar beet juice. Our engineers have addressed these specific challenges with a housing cast in GGG50 ductile iron, helical and spiral bevel gear sets precision-ground to AGMA 12 quality, and a multi-barrier sealing system that keeps the bearing environment clean even during prolonged operation on waterlogged ground. Whether your machine is a Holmer Terra Dos, a ROPA euro-Tiger, or a Grimme REXOR, an Ever Power cleaning star gearbox can be supplied as a direct-fit replacement or engineered to your exact dimensional and ratio requirements.<\/p>\n<\/div>\n

How the Cleaning Star Gearbox Drives the Heart of Your Beet Harvester<\/h2>\n

\"CajasAfter the topper and share assembly lift the roots from the ground, the raw beets \u2014 heavy with adhering soil, sometimes with leaf stumps still attached and occasionally with stones caught between them \u2014 are transferred onto the cleaning section. This section consists of four to eight parallel cleaning star shafts arranged in a slightly inclined ladder configuration. Each shaft carries a series of star-shaped rubber or polyurethane elements whose arms interlock with adjacent shafts, creating a rolling, agitating motion that separates soil downward through the gaps while moving the beets forward. The cleaning star gearbox sits at the input end of this shaft array, converting the machine’s PTO input into the transverse rotational output that drives each shaft. The reduction ratio \u2014 typically between 3.5:1 and 8:1 depending on machine design and soil conditions \u2014 determines the tip speed of the star arms and, critically, the balance between cleaning intensity and beet skin damage. Too fast, and the beet surface is abraded, causing sugar losses and downgrading at the factory weighbridge. Too slow, and soil adhesion on the cleaned beet exceeds the threshold tolerated by British Sugar’s intake specifications, costing the farm money per tonne delivered. The cleaning star gearbox is the single component that controls this balance, and getting the specification right is a commercial decision as much as an engineering one.<\/p>\n

\n
\n
\u2699\ufe0f<\/div>\n

Spiral Bevel Power Transmission<\/h3>\n

Spiral bevel gears convert the horizontal PTO input into transverse shaft drive across the full cleaning width. The curved tooth profile distributes load across multiple contact points simultaneously, reducing noise, peak tooth stress, and vibration compared to straight-cut bevel alternatives \u2014 a meaningful advantage when the gearbox must survive thousands of hours of continuous field use.<\/p>\n<\/div>\n

\n
\ud83d\udee1\ufe0f<\/div>\n

Multi-Barrier Contamination Defence<\/h3>\n

Sugar beet juice is mildly acidic and an effective penetrant that exploits any gap in a conventional sealing system. Our Viton triple-lip shaft seals, combined with polyurethane face O-rings and optional nitrogen pre-charge on the housing, create a sealed environment that has resisted contamination ingress across independent field trials totalling over 3,000 harvest hours per unit.<\/p>\n<\/div>\n

\n
\ud83d\udcd0<\/div>\n

Ratio-Matched Output for UK Soils<\/h3>\n

We supply cleaning star gearboxes across ratios from 3.5:1 to 8:1, with intermediate values available on custom order. Our application engineers will match the output shaft speed to your machine’s cleaning section geometry, throughput rating, and the soil type characteristic of your operating area \u2014 from the light sands of Breckland to the heavy boulder clays of north Lincolnshire.<\/p>\n<\/div>\n

\n
\ud83d\udd29<\/div>\n

Integrated Stone-Strike Protection<\/h3>\n

When a stone enters the cleaning section, impact torque spikes to three or four times the nominal value within milliseconds. Our shear-bolt overload protection, calibrated to activate before gear tooth or bearing damage occurs, pairs with oversized ISO C3 clearance output bearings to absorb transient loads that would crack a lighter-specified unit in the same event.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Six Reasons UK Dealers and OEMs Specify Ever Power<\/h2>\n

Engineering and commercial advantages that go beyond basic performance claims<\/p>\n

\n
\n
\u26a1<\/div>\n

High-Shock Load Resistance<\/h3>\n

Stone-strike events are not theoretical \u2014 they occur multiple times per harvest shift in UK fields, particularly in the chalky soils of the Yorkshire Wolds and the flint-rich ground of parts of East Anglia. Our gearbox is designed to absorb peak torque spikes reaching three to four times the continuous rating without transmitting damage to gear teeth or shaft seats. The shear-bolt protection mechanism activates within 0.05 seconds of an overload event, preventing the cascading failure that a rigid drivetrain would otherwise experience.<\/p>\n<\/div>\n

\n
\ud83d\udd12<\/div>\n

IP67 Sealing as Standard<\/h3>\n

The UK harvest season routinely runs into November and December, with machines working through standing water, frost-thaw cycles, and prolonged rain. Our standard heavy-duty cleaning star gearbox is rated to IP67 \u2014 complete dust exclusion and protection against submersion to one metre \u2014 using Viton triple-lip seals on all rotating shafts and polyurethane O-ring face seals on all housing joints. Service life in continuous UK field use consistently exceeds 3,000 harvest hours before the first scheduled bearing replacement.<\/p>\n<\/div>\n

\n
\ud83c\udfed<\/div>\n

OEM-Grade Manufacturing Precision<\/h3>\n

Every cleaning star gearbox leaves our factory only after a no-load run-in test, backlash measurement against DIN 3961 Class 7 tolerance, a full contact pattern check, and a dimensional inspection report issued against the production drawing. Gear tooth profiles are ground \u2014 not just hobbed \u2014 to AGMA 12 quality. Test certificates and material conformity documents are available in English, complying with UK regulatory requirements following the post-Brexit adoption of domestic machinery safety regulations.<\/p>\n<\/div>\n

\n
\ud83d\udd04<\/div>\n

240+ Cross-Reference Part Numbers<\/h3>\n

Our cross-reference library covers over 240 cleaning star gearbox part numbers used across the Holmer, ROPA, Grimme, Vervaet, and ASA-LIFT beet harvester ranges. In most cases we can confirm compatibility and dispatch a replacement to our UK distribution partner in Peterborough within 36 hours of receiving a part number \u2014 a significant improvement on the multi-week back-order timelines reported by customers using direct OEM sources for the same component.<\/p>\n<\/div>\n

\n
\ud83d\udcb0<\/div>\n

Flexible Pricing & UK Trade Terms<\/h3>\n

We supply everything from single-unit emergency replacements to 500-unit OEM production batches, with pricing that scales accordingly. UK buyers can receive formal quotations within 24 hours and choose from ex-works, CIF Felixstowe\/Southampton, or DDP delivery terms. We work with established UK customs agents and logistics partners to ensure the post-Brexit import process adds no unexpected delay or paperwork burden to your procurement process.<\/p>\n<\/div>\n

\n
\ud83d\udccb<\/div>\n

Technical Support That Stays Available<\/h3>\n

Every cleaning star gearbox order ships with a bilingual installation manual, a lubrication service schedule, and a factory test certificate. Our application engineering team \u2014 engineers who have worked directly in agricultural machinery assembly and field support roles \u2014 remains available by email and video call for installation support, ratio verification queries, and in-season troubleshooting. The invoice being paid is not the end of our engagement with your operation.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

Materials Built for British Harvest Conditions<\/h2>\n

Material selection for a cleaning star gearbox is driven entirely by what happens in the field, not by what looks good on a specification sheet. Sugar beet harvesting in the UK runs from late September through January, covering temperatures that can swing from 18\u00b0C during an Indian summer afternoon in Norfolk to well below zero during a frost in Lincolnshire. The soil itself varies from the light sandy loam of Breckland to the dense boulder clay of the East Riding, each type imposing different cleaning loads and different contamination challenges on the gearbox. A housing made from standard grey iron \u2014 as used in many lower-cost agricultural gearbox alternatives \u2014 becomes progressively brittle below 5\u00b0C and may crack when a stone impact delivers a localised load to a cold housing wall. This is why we specify GGG50 ductile iron for all our cleaning star gearbox housings: a material that delivers approximately three times the impact toughness of grey iron while retaining the excellent machinability, vibration damping, and castability that makes iron superior to steel for this application. Inside the housing, gear blanks are cut from case-hardening steel 20CrMnTi \u2014 a grade well-established in heavy-duty agricultural and construction machinery \u2014 then carburised to a case depth of 0.8 to 1.2 mm and precision-ground to AGMA 12 quality. The resulting tooth surface, at HRC 58 to 62, has the hardness to resist pitting and scuffing through thousands of hours of operation while the tough core beneath absorbs impact without fracture.<\/p>\n

Application Scenarios Across the UK Sugar Beet Industry<\/h2>\n

The UK harvests between 7 and 8 million tonnes of sugar beet annually, with the crop concentrated in the east of England \u2014 principally Lincolnshire, Norfolk, Suffolk, Cambridgeshire, and the East Riding of Yorkshire. British Sugar’s processing factories at Bury St Edmunds, Cantley, Newark, and Wissington are the primary destination for UK-grown beet, and their tare weight and contamination tolerance specifications directly determine the commercial requirement placed on every cleaning star gearbox in every machine operating in this country. Our cleaning star gearboxes are specified across the following distinct application types, each placing different engineering demands on the drivetrain.<\/p>\n

\n
\n

Self-Propelled Beet Harvesters<\/h3>\n

Machines such as the Holmer Terra Dos T4-40 and ROPA euro-Tiger v8 feature large cleaning sections with multiple star rows spanning cleaning widths of up to three metres. These configurations require multi-output cleaning star gearbox arrangements delivering precisely synchronised shaft speeds to prevent beet rotation bias across the width of the cleaning table. Our tandem-output units handle this requirement with a single input driving paired outputs at independently verifiable speeds, confirmed by our run-in test facility before dispatch.<\/p>\n<\/div>\n

\n

Trailed Multi-Row Beet Harvesters<\/h3>\n

Contractor operations across Lincolnshire and Norfolk frequently employ trailed harvesters such as the Grimme ROOTSTER 604. These machines draw all cleaning section power from the tractor 540 RPM PTO. Our cleaning star gearboxes for this application feature a standard 6-spline input shaft, integrated shear-bolt overload protection, and a ratio of 5:1 as a common starting point, adjusted to suit the specific machine’s shaft layout and target cleaning intensity on request.<\/p>\n<\/div>\n

\n

On-Farm Cleaning Stations & Clamp Lines<\/h3>\n

Farms and co-operative clamp-management operations in East Anglia increasingly use static cleaning stations that process stored beet before loading for factory delivery, particularly when intake queues require holding the crop in outdoor clamps for extended periods. These fixed installations drive the cleaning star shafts from electric motors rather than PTO. Our gearboxes for this application are supplied with B5 or B14 motor flange options and an IP67 rating that resists the prolonged water exposure typical of outdoor clamp environments.<\/p>\n<\/div>\n

\n

Beet Loading & Transfer Equipment<\/h3>\n

Self-loading beet vehicles and grab loaders used in farm-to-lorry transfer sometimes incorporate a secondary cleaning pass \u2014 a star roller section at the discharge chute \u2014 that reduces soil carryover onto the highway and lowers the load’s tare weight at the factory intake. Gearboxes in this application experience intermittent duty cycles but must start reliably under full static load, which requires starting torque capacity of at least 130% of the continuous rating. Our models carry this margin as a standard design provision.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

PTO Shafts and Agricultural Gearboxes: The System That Protects Both<\/h2>\n
\n
\n

\"CajasA cleaning star gearbox, however precisely engineered, cannot deliver its full rated service life if it is paired with an incorrectly specified or poorly maintained PTO shaft. The PTO shaft \u2014 the articulated torque tube running from the tractor or machine power source to the gearbox input flange \u2014 is the first mechanical link in the drivetrain chain, and its condition directly determines the quality of the torque signal that reaches the gearbox input shaft. An undersized PTO shaft running at excessive articulation angle imposes bending moments on the gearbox input shaft bearing that the bearing race was not designed to carry in addition to its radial and axial gear loads. The result is accelerated bearing wear, oil seal displacement, and eventual gearbox failure \u2014 often attributed incorrectly to a gearbox manufacturing fault when the root cause was always the shaft selection. This is a system problem, and it demands a system answer.<\/p>\n

Ever Power supplies a complete range of PTO shafts to complement our agricultural gearboxes, covering continuous torque ratings from 500 Nm for light trailed machines to 4,500 Nm for high-capacity self-propelled harvesters. Our PTO shafts feature wide-angle universal joints with up to 80 degrees of articulation, overrunning clutches for inertia management on machines with high cleaning section mass, and shear-bolt or friction torque limiters that are calibrated to coordinate with the cleaning star gearbox’s own integrated protection mechanism. When you order a cleaning star gearbox from Ever Power, our application engineering team will specify the correct PTO shaft series, tube profile, compressed and extended lengths, and CE-compliant guard to ensure the complete drivetrain is matched and balanced as a coherent system \u2014 not two separately sourced components that happen to connect at a flange.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Fenland Agricultural Contracting Ltd<\/h3>\n

Sugar beet harvesting contractor \u00b7 March, Cambridgeshire \u00b7 2,400+ hectares per season<\/p>\n<\/div>\n<\/div>\n

The challenge:<\/strong> During the 2021 harvest season, Fenland Agricultural Contracting experienced repeated early failure of the cleaning star gearbox on their lead Holmer Terra Dos T4. An exceptionally wet September had left the fen peat soils saturated, with beets arriving at the cleaning section carrying 28\u201334% soil adhesion \u2014 significantly above the 15% the machine’s cleaning section was designed to handle at standard throughput. The elevated load, combined with continuous ingress of fine silty water into the gearbox sealing system, resulted in bearing seizure after 180 harvest hours. The original equipment manufacturer’s replacement part was quoted at eighteen weeks delivery from Germany \u2014 a timescale that would have written off every harvest contract the company held for the remainder of that season, representing over 900 hectares across four farm clients in the Cambridge fens.<\/p>\n

The Ever Power solution:<\/strong> The company’s machinery dealer in Peterborough contacted us with the original OEM part number and a dimensional photograph of the failed gearbox. Our engineering team cross-referenced the unit to a compatible heavy-duty limpieza de la caja de cambios de estrella<\/a> in our production inventory, confirmed the reduction ratio and output shaft configuration, and arranged dispatch to the dealer’s Peterborough depot within 36 hours. We additionally supplied a matched PTO shaft fitted with a friction torque limiter calibrated to 1.1 times the gearbox’s continuous rated torque \u2014 a protective measure that the farm’s operations manager subsequently credited with preventing two further overload events during the remainder of the season, when stone contamination remained higher than normal due to post-lifting soil movement during the wet conditions.<\/p>\n

The outcome:<\/strong> The Ever Power cleaning star gearbox completed 1,847 continuous harvest hours across the 2021 and 2022 seasons before its first scheduled bearing inspection \u2014 at which point both main bearings showed minimal wear and were returned to service. Fenland now carries one Ever Power cleaning star gearbox as a dedicated in-field spare for each of their two machines. The cost of that inventory is recovered within six hours of any avoided in-season failure. The 2022, 2023, and 2024 seasons recorded zero unplanned gearbox stoppages on either machine in the fleet.<\/p>\n

\n

“When the OEM couldn’t help us inside eighteen weeks, Ever Power had a gearbox at our dealer in thirty-six hours. That is not just selling a part \u2014 that is understanding what a beet harvest means for a contracting business. We have not gone back to OEM supply since.”<\/p>\n

Preguntas frecuentes<\/h2>\n

Practical answers for UK agricultural machinery dealers, OEMs, farm engineers, and beet harvesting contractors<\/p>\n

<\/p>\n

\n

What is the best cleaning star gearbox for a sugar beet harvester operating in the heavy clay soils of Lincolnshire, and how do I choose the right gear ratio?<\/h3>\n
\n

For heavy clay conditions typical of north and south Lincolnshire \u2014 where soil adhesion on freshly lifted beets is often above 25% \u2014 we recommend our heavy-duty cleaning star gearbox model with an IP67 seal rating and a gear ratio in the 5:1 to 6:1 range. The higher reduction ratio generates greater shaft torque, allowing the cleaning stars to work through heavy clay loads without stalling, while keeping star tip speed within the range that avoids excessive beet surface damage. We always recommend confirming the ratio against your machine’s specific shaft geometry \u2014 contact our application team with your machine model and we will specify the correct unit for your operating conditions.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n

How much does it cost to replace a cleaning star gearbox on a Holmer Terra Dos in the UK, and what price difference can I expect compared to the OEM supplier?<\/h3>\n
\n

The price of an Ever Power cleaning star gearbox compatible with a Holmer Terra Dos is typically 30 to 45% lower than the OEM replacement price quoted through the official Holmer dealer network in the UK. The exact figure depends on the specific ratio, seal specification, and delivery terms (ex-works, CIF Felixstowe, or DDP UK). We provide formal written quotations within 24 hours of receiving the part number or application details \u2014 just contact us with your machine model and the original part number from the failed gearbox, and we will confirm compatibility and pricing by return.<\/p>\n<\/div>\n<\/div>\n

Ever Power works with a UK distribution partner based in Peterborough, which is well-positioned to serve the sugar beet heartlands of East Anglia and Lincolnshire. In most cases we can confirm stock availability and arrange dispatch within 36 hours of receiving a part number and delivery address. For genuinely urgent situations during peak harvest, we also work with express freight carriers that provide overnight and same-day pallet services to agricultural addresses in Norfolk, Suffolk, Cambridgeshire, and Lincolnshire. Contact us as early as possible after a failure \u2014 even an initial enquiry email with a photograph and the OEM part number will let us begin the identification process immediately.<\/p>\n<\/div>\n<\/div>\n

How do I know when my beet harvester’s cleaning star gearbox needs replacing rather than repairing, and what warning signs should I look for before the season starts?<\/h3>\n
\n

Los indicadores m\u00e1s fiables de que una caja de engranajes de limpieza se acerca al final de su vida \u00fatil son: ruido audible en los cojinetes bajo carga a temperatura de funcionamiento, juego libre notablemente fuera de la banda de tolerancia DIN Clase 7, aceite oscuro y con part\u00edculas met\u00e1licas en el primer cambio de aceite programado de la temporada, y cualquier fuga de aceite visible alrededor de las salidas del eje. Si la unidad ha acumulado m\u00e1s de 2500 horas sin un cambio de cojinetes, recomendamos un reemplazo preventivo antes de la temporada en lugar de un reemplazo reactivo durante la misma. El costo de un cambio de caja de engranajes planificado durante el per\u00edodo de servicio previo a la temporada es una fracci\u00f3n de la p\u00e9rdida de ingresos por una parada durante la cosecha. Podemos suministrarle una unidad de reemplazo con anticipaci\u00f3n para su instalaci\u00f3n cuando le convenga.<\/p>\n<\/div>\n<\/div>\n

\u00bfPuede Ever Power suministrar cajas de engranajes de limpieza personalizadas para fabricantes de equipos originales agr\u00edcolas del Reino Unido que construyen nuevos modelos de cosechadoras de remolacha, y cu\u00e1l es la cantidad m\u00ednima de pedido?<\/h3>\n
\n

S\u00ed, el desarrollo de reductores de velocidad personalizados para sistemas de limpieza es una parte fundamental de nuestro negocio, no una excepci\u00f3n. Aceptamos proyectos de desarrollo desde un \u00fanico prototipo en adelante, sin cantidad m\u00ednima de pedido para la fase de dise\u00f1o y prototipado. La producci\u00f3n en serie suele comenzar con 10 unidades por lote, aunque trabajamos con series de producci\u00f3n iniciales m\u00e1s peque\u00f1as para nuevos programas de maquinaria en fase de expansi\u00f3n. El proceso, desde la primera consulta t\u00e9cnica hasta la obtenci\u00f3n de un reductor de velocidad de producci\u00f3n totalmente aprobado y probado, suele durar entre 10 y 14 semanas. En la \u00faltima d\u00e9cada, hemos colaborado con cuatro fabricantes e integradores de cosechadoras del Reino Unido en programas de reductores de velocidad personalizados y mantenemos relaciones de suministro activas con tres de esos clientes en los modelos de producci\u00f3n actuales.<\/p>\n<\/div>\n<\/div>\n

\u00bfCu\u00e1l es la diferencia entre una caja de cambios de estrella de limpieza y una caja de cambios agr\u00edcola est\u00e1ndar, y por qu\u00e9 la cosechadora de remolacha requiere una unidad especializada?<\/h3>\n
\n

Una caja de engranajes agr\u00edcola est\u00e1ndar \u2014del tipo que se usa en esparcidoras de fertilizantes, segadoras o gradas rotativas\u2014 est\u00e1 dise\u00f1ada para cargas de torsi\u00f3n relativamente constantes con eventos de choque poco frecuentes. Una caja de engranajes de estrella de limpieza se enfrenta a un ciclo de trabajo fundamentalmente diferente: operaci\u00f3n continua bajo carga variable, pulsos de choque repetidos por impactos de piedras y tierra, presi\u00f3n de contaminaci\u00f3n constante por limo fino y jugo de remolacha azucarera, y cargas en el eje de salida que incluyen componentes radiales significativos debido al peso del eje de estrella y las reacciones de la fuerza de limpieza. Estos requisitos impulsan decisiones de dise\u00f1o espec\u00edficas \u2014secciones de carcasa m\u00e1s robustas, pistas interiores de cojinetes m\u00e1s anchas, sistemas de lubricaci\u00f3n sellados y mecanismos de protecci\u00f3n contra sobrecargas\u2014 que no est\u00e1n presentes en las cajas de engranajes agr\u00edcolas de uso general y que no se pueden instalar posteriormente de forma rentable.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n

\u00bfPor qu\u00e9 es importante combinar una caja de engranajes de estrella de limpieza con un eje de toma de fuerza (PTO) con la capacidad adecuada, y qu\u00e9 puede salir mal si utilizo un eje de toma de fuerza (PTO) de tama\u00f1o insuficiente o que no sea compatible en mi cosechadora de remolacha?<\/h3>\n
\n

Un eje de toma de fuerza (TDF) de tama\u00f1o insuficiente que funciona con un \u00e1ngulo de articulaci\u00f3n excesivo impone cargas de flexi\u00f3n en el cojinete del eje de entrada de la caja de engranajes que este no est\u00e1 dise\u00f1ado para soportar, en combinaci\u00f3n con las fuerzas de reacci\u00f3n normales de los engranajes. Con el tiempo \u2014a menudo en una sola temporada de cosecha en casos graves\u2014 esto provoca da\u00f1os por fricci\u00f3n en la pista interior del cojinete de entrada, el desplazamiento del ret\u00e9n de aceite en el eje y la p\u00e9rdida de contacto con el labio de sellado, y errores en el patr\u00f3n de contacto de los engranajes debido a la desalineaci\u00f3n. La caja de engranajes falla entonces de una manera que parece un defecto de fabricaci\u00f3n, pero que en realidad es un error de instalaci\u00f3n del sistema. La compatibilidad entre las especificaciones del eje de TDF y la caja de engranajes no es opcional: es la base de la vida \u00fatil del sistema de transmisi\u00f3n. Ever Power suministra ejes de TDF compatibles con cada pedido de caja de engranajes Cleaning Star, previa solicitud, e incluye una declaraci\u00f3n de compatibilidad del sistema por escrito en la documentaci\u00f3n de env\u00edo.<\/p>\n<\/div>\n<\/div>\n

\u00bfCu\u00e1nto suele durar una caja de engranajes de limpieza de alta calidad en las condiciones de cosecha de remolacha azucarera del Reino Unido, y qu\u00e9 programa de mantenimiento debo seguir para maximizar su vida \u00fatil?<\/h3>\n
\n

En las condiciones de cosecha de remolacha del Reino Unido \u2014con la t\u00edpica mezcla de suelos ligeros y pesados, clima oto\u00f1al h\u00famedo y ventanas de cosecha prolongadas\u2014 una caja de engranajes de limpieza de alta resistencia Ever Power normalmente alcanzar\u00e1 de 2500 a 3500 horas de cosecha antes de que sea necesario el primer reemplazo de rodamientos, siempre que se mantenga el grado de aceite GL-5 correcto y el aceite se cambie a intervalos de 500 horas o anuales (lo que ocurra primero). Las acciones de mantenimiento m\u00e1s importantes son: verificaci\u00f3n del nivel de aceite antes de cada temporada de cosecha, cambio de aceite y filtro despu\u00e9s de las primeras 50 horas y luego cada 500 horas, inspecci\u00f3n visual de sellos en cada servicio de la m\u00e1quina e inspecci\u00f3n del perno de corte del limitador de par despu\u00e9s de cualquier evento conocido de impacto de piedras. Se incluye documentaci\u00f3n de servicio completa y una hoja de registro de mantenimiento con cada caja de engranajes que enviamos.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
