EP worm gearboxes possess earned a status to be an industry benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes happen to be affordable prices. High versatility accorded through a broad choice of mounting choices, shaft configurations and electric motor interfaces, makes the EP worm gearbox the default choice for the industry. 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 great torque with low rate gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix position is typically comparatively larger) and its own body is generally quite long in the axial path. The gears in these gearboxes could be right or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is usually shaped such as a screw and the worm wheel is usually a kind of gear machined to have a tooth profile with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is the same as a nut that is fixed so that it cannot rotate and for that reason progresses in the axial direction when the bolt is turned.
The look of a worm gear is considered through the relationship between the rack and spur gear on the center plane of the worm wheel.
Features
Great reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. For this reason, in a 1 speed reduction gears, the wheel can be manufactured thus 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 a 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 switch 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 top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Physique 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 usually characteristic since the contact is linear and the relative slide is great. In comparison to rolling power transmission, sound and vibration are really low. Because of this, this technology can be used 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 correct 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 important areas such as for example selecting the strain index, calculating the overhang load and examining heat rated potential from the manufacturer.
Cautions during use
When utilizing a worm reduction 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 decrease 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 after that about 1 time per year according to the procedure manual presented 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, 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 range of applications and higher efficiency compared to the compact line XC, where the emphasis is on space efficiency.
Series H supplies the same features because series X with an extra plus: a spur gear pre-stage at the insight end provides higher performance and a broader selection of ratios than 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 is supplied as standard.
Broad range of possibilities:
second input, output flange, single or dual extension result shaft, torque limiter with through cable connection, torque arm.
