EP worm gearboxes possess 
earned a popularity to be a business benchmark worldwide. Our success came 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 broad choice of mounting options, shaft configurations and motor interfaces, creates the EP worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide huge torque with low acceleration 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 characteristics act like helical gears, but its helix angle is typically comparatively larger) and its body is generally quite long in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting option include universal housing, side 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 type of interlocking gear composed of a good worm shaft and worm wheel. The worm can be shaped like a screw and the worm wheel is definitely a kind of gear machined to own a tooth account with the same configuration.
The procedure of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that is fixed to ensure that it cannot rotate and for that reason progresses in the axial direction when the bolt is usually turned.
The look of a worm gear is considered through the relationship between your rack and spur gear on the center plane of the worm wheel.
Features
Huge reduction ratio One rotation of the worm rotates the worm wheel by one tooth. For this reason, in a 1 speed decrease gears, the wheel could be manufactured consequently that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic can help you layout the turning transmission 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 modification the rotation path of the worm wheel by changing the screw path.
A wide variety 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., combine for a complete of 14 types (Number 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 definitely characteristic since the contact is usually linear and the relative slide is great. In comparison to rolling power transmission, sound and vibration are extremely low. Because of this, this technology is used to drive medical devices, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When selecting 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 crucial areas such as selecting the strain index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm reduction gears, heat produced through the initial period 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 to change the lubricating oil after that about 1 time per year according to the procedure manual given 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 housing + coupling) offers great versatility to suit a broad selection of applications and higher efficiency compared to the compact collection XC, where the emphasis is on space effectiveness.
Series H offers the same features because series X with an added plus: a spur equipment pre-stage at the input end provides higher overall performance and a good broader selection of ratios compared to the X series.
Frame sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use 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 is supplied as standard.
Broad range of possibilities:
second input, result flange, single or double extension output shaft, torque limiter with through cable, torque arm.
