EP worm gearboxes have earned a status to be a business benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, makes the EP worm gearbox the default decision for the industry. 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 huge torque with low velocity gear ratio. Being basic 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 angle 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, 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
Principles
A worm gear is a kind of interlocking gear made up of a worm shaft and worm wheel. The worm can be shaped such as a screw and the worm wheel is certainly a kind 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 has been fixed so that it cannot rotate and therefore progresses in the axial path when the bolt is turned.
The design of a worm gear is thought of through the relationship between the rack and spur gear on the center plane of the worm wheel.
Features
Substantial 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 could be manufactured therefore that it will be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic can help you layout the turning tranny 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 multitude of shaft layouts The wide selection of shaft layouts is among the top features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Number 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 definitely linear and the relative slide is excellent. In comparison to rolling power transmission, sound and vibration are extremely low. For this reason, this technology is utilized to drive medical devices, 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 ought to be selected according to those procedures. Particular care ought to be taken in crucial areas such as selecting the load index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm decrease 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 reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to improve the lubricating oil and to change the lubricating oil from then on about 1 time per year according to the operation manual provided by the manufacturer.

The worm reduction gears come in two series: X and H.
The series X, featuring 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) provides great versatility to match a broad selection of applications and higher efficiency compared to the compact series XC, where in fact the emphasis is on space effectiveness.
Series H offers the same features since series X with an added plus: a spur equipment pre-stage at the insight end provides higher functionality and a good broader range of ratios compared to the X series.
Framework 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 manufactured from casehardened and hardened alloy metal 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 possibilities:
second input, result flange, single or dual extension output shaft, torque limiter with through cable connection, torque arm.
