EP worm gearboxes possess earned a status to be an industry benchmark worldwide. Our achievement originated from our relentless drive for top quality with state-of-the-artwork technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, makes the EP worm gearbox the default choice for the market. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide great torque with low swiftness gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its body is normally quite long in the axial path. The gears in these gearboxes can be correct or left-handed depending upon the purpose.
Mounting option include universal housing, aspect 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
Principles
A worm gear is a type of interlocking gear composed of a good worm shaft and worm wheel. The worm can be shaped just like a screw and the worm wheel is a type of gear machined to have a tooth profile with the same configuration.
The operation of a worm gear is comparable with that of a bolt and nut. The principle is equivalent to a nut that has been fixed to ensure that it cannot rotate and for that reason 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
Huge reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. Due to this, in a 1 speed reduction gears, the wheel can be manufactured thus that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic makes it possible to layout the turning transmission direction at the 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 modification the rotation path of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide variety of shaft layouts is among the features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine 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 usually characteristic since the contact can be linear and the relative slide is fantastic. In comparison to 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 selecting a worm reduction gears
Selection
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 key areas such as for example selecting the load index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm decrease gears, the heat produced during the initial period of use is large and running-in operation 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 reduction gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it is necessary to improve the lubricating oil and to change the lubricating oil from then on about 1 time each year according to the operation manual offered 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 casing + coupling) provides great versatility to match a broad selection of applications and provides higher efficiency than the compact range XC, where the emphasis is on space effectiveness.
Series H offers the same features because series X with an extra 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.
Body sizes 110 and 90 include 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 comes as standard.
Broad range of options available:
second input, output flange, single or dual extension output shaft, torque limiter with through wire, torque arm.
