Immediate coupling between servo electric motor and worm gear is among the key strengths of EP worm gearmotors, which combine DC motor technology with exceptional sturdiness and wear resistance. Motor and gearbox were created as you single, compact unit. Because of their reduced current attract, these gearmotors deliver more accurate control of operating temperature and higher efficiency.

We deliver worm gearboxes, spur gearboxes and planetary gearboxes with or without integrated linear lead screw / ball screw adapted to our flexible modular concept.
Based on this we can select a wide variety of standard customizations to meet up the requirements of varied properties that are important for each application.
If your application requires a gearbox with some special property or home such as small dimensions or low weight with regards to power, high efficiency, quiet and vibration-free operation, long life, high level of resistance to vibration, pressure or temperature, integrated linear screw, or a combination of this kind of properties, our product range with more than 1000 different standard gearboxes is probably a good begin to be able to deliver something that stands out in your favor.
Small gearboxes are high-quality gearboxes for regular drives. The electric engine is included with the gearbox into a single unit (the first equipment is on the electric motor shaft). Separate gearboxes for connection to conventional IEC motors may also be supplied on request.
Because of the complexity of the gearboxes’ configuration, they cannot be purchased in our e-shop. Our experts will be pleased to help you create your selection. We will be happy to send you documentation or design a suitable set directly, on ask for.

Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix position is typically comparatively larger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
EXCELLENT Geared Motors. Ever-Power gearboxes and geared motors will be the electro-mechanical key components for low backlash, easily running and highly dynamic drive systems.
Our high-performance gear devices are built to withstand the toughest commercial applications.
The apparatus housings are machined on all sides and permit diverse installation positions and applications, making them much popular in the industry. As a result our geared motors tend to be to be found within our customers own machines.
The smooth running of Ever-Power gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported by FEM (Finite Element Method). This tooth geometry ensures optimum rolling get in touch with under load.
The special tooth root style in mixture with tooth helix angle, tooth depth, the components used and surface finish maximizes load capacity. This high gearing capacity enables smaller wheels to be used for the same torque, and smaller sized gears with excellent power density also increase reliability. Ever-Power geared motors are as a result incredible space savers.
Gearing produced with such micro-geometric accuracy allows the gearing perform necessary for troublefree rolling get in touch with to be substantially reduced and then the gear backlash to end up being minimized.
Dual chamber shaft seals produced by Ever-Power are utilized as regular in parallel shaft, shaft installed and helical worm gears for a high level of tightness.
Ever-Power’s modular equipment technology meets certain requirements of advanced drive systems:
Excellent power density
Minimum backlash
Smooth running
Diverse mounting options
Maximum reliability
High variability
