EP worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless get for top quality with state-of-the-artwork technology, all and will be offering worm gearboxes happen to be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, will make the EP worm gearbox the default decision for the sector. 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 excessive torque with low speed gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be right or left-handed dependant on the purpose.
Mounting option include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a kind of interlocking gear composed of a good worm shaft and worm wheel. The worm is definitely shaped just like a screw and the worm wheel can be a type of gear machined to have a tooth account with the same configuration.
The procedure of a worm gear is comparable with that of a bolt and nut. The principle is the same as a nut that has been fixed to ensure that it cannot rotate and for that reason progresses in the axial direction when the bolt can be turned.
The look of a worm gear is considered through the relationship between your 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 simply by one tooth. Due to this, in a 1 speed decrease gears, the wheel can be manufactured so 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 makes it possible to 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). You’ll be able to change the rotation direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide variety of shaft layouts is among the features of interlocking gears.For instance, right shaft output, still 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 select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is definitely characteristic since the contact is linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are really low. For this reason, 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 ought to be selected according to those procedures. Particular care ought to be taken in essential areas such as for example selecting the load index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm lowering gears, the heat produced during the initial period of use is large and running-in procedure 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 is necessary to improve the lubricating oil and also to change the lubricating oil from then on about 1 time each year according to the procedure manual supplied by the manufacturer.

The worm reduction gears come 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) provides great versatility to suit a broad range of applications and provides higher efficiency compared to the compact range XC, where in fact the emphasis is on space efficiency.
Series H supplies the same features as series X with an added plus: a spur equipment pre-stage at the input end provides higher functionality and a good broader selection 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 manufactured 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 possibilities:
second input, result flange, single or double extension result shaft, torque limiter with through wire, torque arm.
