EP worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our success came from our relentless travel for top quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, produces the EP worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide excessive torque with low rate gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be proper or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear made up of a worm shaft and worm wheel. The worm is certainly shaped like a screw and the worm wheel is definitely a type of gear machined to own a tooth profile with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is the same as a nut that has been fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt is certainly turned.
The look of a worm gear is considered through the relationship between the rack and spur gear on the center plane of the worm wheel.
Features
Excessive reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Due to this, in a 1 speed reduction gears, the wheel could be manufactured hence that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature makes it possible to layout the turning transmission direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible to modification the rotation path of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For instance, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Body 2) and, if attachment orientations are included, it is possible to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is usually characteristic since the contact is linear and the relative slide is excellent. In comparison to rolling power transmission, sound and vibration are extremely low. Because of this, this technology is used to drive medical apparatus, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the maker catalogs and the series and models should be selected according to those procedures. Particular care should be taken in key areas such as selecting the strain index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When using a worm lowering gears, the heat produced during the initial amount of use is high and running-in operation at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is paramount to sufficiently attaining the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to improve the lubricating oil and also to change the lubricating oil after that about 1 time each year according to the procedure manual provided by the manufacturer.

The worm reduction gears can be found in two series: X and H.
The series X, having a worm and worm wheel set, is available in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) offers great versatility to match a broad range of applications and provides higher efficiency compared to the compact brand XC, where in fact the emphasis is on space efficiency.
Series H offers the same features as series X with an added plus: a spur gear pre-stage at the input end provides higher functionality and a broader selection of ratios than the X series.
Body sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy metal and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of options available:
second input, output flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
