EP worm gearboxes possess earned a status to be a business benchmark worldwide. Our achievement came from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes happen to be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, would make the EP worm gearbox the default decision for the industry. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide high torque with low quickness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix position is typically comparatively bigger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be right or left-handed dependant on the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), 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 is a kind of gear machined to have a tooth account 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 is fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is definitely turned.
The design of a worm gear is thought of through the relationship between your rack and spur gear on the middle plane of the worm wheel.
Features
Large 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 therefore that it will be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This characteristic can help you layout the turning tranny direction at a 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 switch the rotation direction of the worm wheel by changing the screw path.
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, remaining shaft output, dual shaft input and dual shaft output, etc., incorporate for a complete of 14 types (Physique 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 is certainly characteristic because the contact can be linear and the relative slide is great. In comparison with rolling power transmission, noise and vibration are really low. For this reason, this technology can be used to drive medical products, elevators and escalators, etc.

Key points when choosing 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 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 potential from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, heat produced through 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 key to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to change 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, 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) provides great versatility to suit a broad selection of applications and higher efficiency than the compact range XC, where the emphasis is on space performance.
Series H supplies the same features since series X with an extra plus: a spur equipment pre-stage at the insight end provides higher overall performance and a good broader range of ratios compared to the X series.
Framework 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 steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow output shaft comes as standard.
Broad range of possibilities:
second input, result flange, single or double extension result shaft, torque limiter with through cable connection, torque arm.
