EP worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and engine interfaces, creates the EP worm gearbox the default decision 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 high torque with low rate gear ratio. Being simple and compact in design, these gears can perform 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 bigger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect 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 worm shaft and worm wheel. The worm is certainly shaped such as a screw and the worm wheel is a kind of gear machined to get a tooth account with the same configuration.
The procedure of a worm gear is comparable with that of a bolt and nut. The principle is equivalent to a nut that has been fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The design of a worm gear is considered through the relationship between your rack and spur gear on the center plane of the worm wheel.
Excessive reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed reduction gears, the wheel could be manufactured thus that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature can help you layout the turning transmitting direction at a 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 change 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 one of the top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Shape 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 can be characteristic because the contact can be 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 apparatus, elevators and escalators, etc.

Key points when selecting a worm reduction gears
When choosing a worm reduction gears, the procedures for selecting the right gear are described in the manufacturer catalogs and the series and models should be selected according to those procedures. Particular care ought to be taken in essential areas such as selecting the load index, calculating the overhang load and examining the heat rated potential from the manufacturer.
Cautions during use
When utilizing a worm lowering gears, heat produced through the initial amount 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 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 operation manual offered by the manufacturer.
The Worm Decrease Gear Box is supplied by our company is of supreme quality. Our products are created through the use of premium quality materials and advance technology at our vendors end. They are widely used in a variety of sectors. Our items are often available at a very low market prices.

Wormgears of the VF series are 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 selection of several mounting options, shaft configurations and motor interface, all offered as standard. The helicalworm and the doubleworm edition, with or without the torque limiter, also accumulate, creating a highly versatile drive system.
20 degree 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, comes in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) offers great versatility to suit a broad range of applications and provides higher efficiency than the compact brand XC, where in fact the emphasis is on space performance.
Series H offers the same features since series X with an extra plus: a spur equipment pre-stage at the input end provides higher performance and a good broader range of ratios compared to the X series.
Framework sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes make use of die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow output shaft is supplied as standard.
Broad range of options available:
second input, output flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
