EP worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our achievement originated 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 broad choice of mounting options, shaft configurations and electric motor interfaces, makes the EP worm gearbox the default choice for the sector. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide huge torque with low velocity gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes can be correct 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 (solitary 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 can be shaped just like a screw and the worm wheel can be a type of gear machined to have a tooth account with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that is fixed to ensure that it cannot rotate and for that reason progresses in the axial direction when the bolt is definitely turned.
The design of a worm gear is thought of through the relationship between your rack and spur gear on the center plane of the worm wheel.
High reduction ratio One rotation of the worm rotates the worm wheel by one tooth. For this reason, in a 1 speed reduction gears, the wheel can be manufactured therefore that it will be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature makes it possible to layout the turning transmitting 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 direction of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide selection of shaft layouts is one of the top features of interlocking gears.For example, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., incorporate for a complete 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 definitely characteristic since the contact is usually linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are extremely low. Because of this, this technology is utilized to drive medical devices, elevators and escalators, etc.

Key points when choosing a worm reduction gears
When choosing 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 ought to be taken in crucial areas such as for example selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm lowering gears, heat produced through the initial period of use is high and running-in procedure at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is paramount to sufficiently achieving the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it’s important to change the lubricating oil and to change the lubricating oil from then on about 1 time each year according to the operation manual supplied by the manufacturer.
The Worm Decrease Gear Box is provided by our company is of high-quality. Our products are made through the use of premium quality material and advance technology at our vendors end. They are widely used in a variety of sectors. Our items are often available at an extremely low market prices.

The worm reduction gears come in two series: X and H.
The series X, featuring 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 higher efficiency compared to the compact collection XC, where the emphasis is on space efficiency.
Series H supplies the same features since series X with an extra plus: a spur equipment pre-stage at the insight end provides higher efficiency and a broader selection of ratios than the X series.
Body sizes 110 and 90 feature a cast-iron casing 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 result shaft is supplied as standard.
