EP worm gearboxes have earned a reputation to be a business benchmark worldwide. Our achievement originated from our relentless travel for quality with state-of-the-art 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, creates the EP worm gearbox the default decision for the sector. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide large torque with low quickness gear ratio. Being simple and compact in style, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is normally quite lengthy in the axial path. The gears in these gearboxes can be proper 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 (one or double), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear made up of a good worm shaft and worm wheel. The worm is usually shaped just like a screw and the worm wheel can be a kind of gear machined to have got 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 the same as a nut that is fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is certainly turned.
The design of a worm gear is thought of through the relationship between the rack and spur gear on the middle plane of the worm wheel.
Features
Excessive 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 consequently that it will be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This characteristic 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). You’ll be able to change the rotation direction 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 instance, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Determine 2) and, if attachment orientations are included, you’ll be able to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel can be characteristic because the contact is certainly linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are really low. For this reason, this technology is utilized to drive medical tools, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When choosing a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer 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 for example selecting the load index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, heat produced through the initial amount of use is high and running-in operation at 1/4, 1/2 and 3/4 of rated torque for eight hour 
periods is paramount to sufficiently attaining the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in operation (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 provided by the manufacturer.

The worm reduction gears can be found 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 selection of applications and higher efficiency compared to the compact brand XC, where in fact the emphasis is on space effectiveness.
Series H supplies the same features as series X with an extra plus: a spur gear pre-stage at the insight end provides higher functionality and a good broader selection of ratios than the X series.
Body 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 produced from casehardened and hardened alloy steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of options available:
second input, result flange, single or dual extension result shaft, torque limiter with through wire, torque arm.
