EP worm gearboxes possess earned a popularity to be a business benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, causes the EP worm gearbox the default choice for the sector. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide large torque with low quickness 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 are similar to helical gears, but its helix position is typically comparatively larger) and its own body is generally quite lengthy in the axial path. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or dual), with torque arm or torque limiter.
Worm reduction gears features
A worm gear is a kind of interlocking gear composed of a good worm shaft and worm wheel. The worm can be shaped such as a screw and the worm wheel can be a type of gear machined to get a tooth account with the same configuration.
The operation of a worm gear is comparable 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 direction when the bolt is turned.
The design of a worm gear is considered through the relationship between your rack and spur gear on the middle plane of the worm wheel.
Huge reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed decrease gears, the wheel can be manufactured thus that it’ll be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature can help you layout the turning transmission direction at the 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 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 top features of interlocking gears.For instance, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Physique 2) and, if attachment orientations are included, you’ll be able to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is certainly characteristic since the contact can be linear and the relative slide is excellent. In comparison to rolling power transmission, noise and vibration are extremely low. Because of this, this technology can be used to drive medical apparatus, elevators and escalators, etc.

Key points when selecting 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 ought to be selected according to those procedures. Particular care ought to be taken in key areas such as selecting the load index, calculating the overhang load and examining heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm decrease 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 decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to change the lubricating oil and also to change the lubricating oil after that about 1 time per year according to the operation 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. They are widely used in various sectors. Our items are often available at a very low market prices.

Wormgears of the VF series are actually milestones for the industry worldwide. They succeeded in combining uncompromising quality with stateoftheart technology amd renown price effectiveness.Absolute versatility is distributed by the wide choice of several mounting options, shaft configurations and engine interface, all offered as regular. The helicalworm and the doubleworm version, with or without the torque limiter, also accumulate, creating a highly versatile drive system.
20 level C TO 80 degree C
The worm reduction gears come 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) provides great versatility to match a broad selection of applications and higher efficiency compared to the compact range XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features because series X with an extra plus: a spur equipment pre-stage at the insight end provides higher functionality and a broader selection of ratios than the X series.
Frame sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use 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 possibilities:
second input, result flange, single or double extension result shaft, torque limiter with through wire, torque arm.
