EP worm gearboxes have earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless travel for top quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, causes the EP worm gearbox the default choice for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide high torque with low rate gear ratio. Being basic and compact in style, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix position is typically comparatively larger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes can be right or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one 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 good worm shaft and worm wheel. The worm can be shaped like a screw and the worm wheel is usually a kind of gear machined to have a tooth account with the same configuration.
The operation of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that is fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt is certainly turned.
The look of a worm gear is thought of through the relationship between your 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 can be manufactured hence 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 can help you layout the turning tranny 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 variety of shaft layouts is one of 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 (Figure 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 is certainly characteristic since the contact is certainly linear and the relative slide is fantastic. In comparison to rolling power transmission, noise and vibration are really low. For this reason, this technology is utilized to drive medical products, 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 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 strain index, calculating the overhang load and examining heat rated potential from the manufacturer.
Cautions during use
When using a worm decrease gears, the 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 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 also to change the lubricating oil from then on about 1 time per year according to the operation manual presented by the manufacturer.

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 housing + coupling) offers great versatility to suit a broad selection of applications and provides higher efficiency compared to the compact collection XC, where in fact the emphasis is on space efficiency.
Series H offers the same features because series X with an added plus: a spur equipment pre-stage at the insight end provides higher functionality and a good broader selection of ratios compared to the X series.
Framework sizes 110 and 90 include 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 metal and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow result shaft comes as standard.
Broad range of options available:
second input, result flange, single or double extension output shaft, torque limiter with through cable connection, torque arm.
