EP worm gearboxes have earned a status to be an industry benchmark worldwide. Our success came from our relentless get for quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, produces the EP worm gearbox the default decision for the industry. 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.
EP Worm gearboxes provide large torque with low acceleration gear ratio. Being basic and compact in design, 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 position is typically comparatively larger) and its body is normally quite long in the axial direction. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single or double), with torque arm or torque limiter.
Worm reduction gears features
A worm gear is a kind of interlocking gear made up of a good worm shaft and worm wheel. The worm is certainly shaped like a screw and the worm wheel is definitely a kind of gear machined to have got a tooth account with the same configuration.
The operation of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that is fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt is turned.
The look of a worm gear is considered through the relationship between your rack and spur gear on the center plane of the worm wheel.
Great reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. Because of this, in a 1 speed reduction gears, the wheel can be manufactured so that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature can help you layout the turning tranny direction at a right angle.
The arbitrariness of the rotation direction The screw direction of the worm can be clockwise or counterclockwise (generally clockwise). It is possible to transformation the rotation path of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide selection of shaft layouts is among the top features of interlocking gears.For example, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Determine 2) and, if attachment orientations are included, you’ll be able to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is characteristic since the contact is linear and the relative slide is excellent. In comparison with rolling power transmission, sound and vibration are extremely low. Because of this, this technology can be used to drive medical tools, elevators and escalators, etc.

Key points when choosing a worm reduction gears
When selecting a worm reduction gears, the procedures for selecting the right 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 for example selecting the strain index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm lowering gears, heat produced during the initial period of use is large and running-in procedure at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key to sufficiently achieving the performance of the worm reduction 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 from then on about 1 time each year according to the procedure manual given by the manufacturer.
The Worm Reduction Gear Box is supplied by our company is of high-quality. Our products are created through the use of premium quality materials and enhance technology at our vendors end.

Wormgears of the VF series are milestones for the market worldwide. They succeeded in combining uncompromising quality with stateoftheart technology amd renown cost effectiveness.Absolute flexibility is distributed by the wide selection of several installation options, shaft configurations and motor interface, all offered as regular. The helicalworm and the doubleworm version, with or without the torque limiter, also add up, creating a highly versatile drive system.
20 degree C TO 80 degree C
The worm reduction gears can be found in two series: X and H.
The series X, having a worm and worm wheel set, comes in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell housing + coupling) offers great versatility to match a broad selection of applications and higher efficiency than the compact range XC, where the emphasis is on space efficiency.
Series H supplies the same features since series X with an extra plus: a spur gear pre-stage at the input end provides higher performance and a broader range of ratios compared to the X series.
Body sizes 110 and 90 include a cast-iron housing cast enbloc, whereas smaller sizes make use of die-cast aluminium housings. The worm shaft is produced from casehardened and hardened alloy metal and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow output shaft comes as standard.
Broad range of options available:
second input, result flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
