EP worm gearboxes possess earned a status to be an industry benchmark worldwide. Our achievement came from our relentless travel for quality with state-of-the-artwork technology, all and will be offering worm gearboxes happen to be affordable prices. High versatility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, produces the EP worm gearbox the default decision for the market. 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 huge torque with low speed gear ratio. Being basic 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 position is typically comparatively larger) and its own body is normally quite lengthy in the axial direction. The gears in these gearboxes could be proper or left-handed dependant on the purpose.
Mounting option include universal housing, aspect 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
A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm can be shaped such as a screw and the worm wheel is usually a type of gear machined to have 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 the same as a nut that is fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The look of a worm gear is thought of through the relationship between the rack and spur gear on the middle plane of the worm wheel.
High reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. For this reason, in a 1 speed decrease gears, the wheel can 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 tranny direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible to transformation the rotation path of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide selection of shaft layouts is one of the features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., incorporate for a complete of 14 types (Figure 2) and, if attachment orientations are included, it is possible to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is characteristic because the contact is linear and the relative slide is fantastic. In comparison to rolling power transmission, noise and vibration are really low. For this reason, this technology can be used to drive medical gear, elevators and escalators, etc.

Key points when selecting a worm reduction gears
When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer catalogs and the series and models should be selected according to those procedures. Particular care ought to be taken in essential areas such as selecting the load index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When using a worm lowering gears, the heat produced through the initial period of use is high 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 change the lubricating oil and to change the lubricating oil from then on about 1 time per year according to the operation manual supplied by the manufacturer.
The Worm Reduction Gear Box is supplied by our company is of supreme quality. Our products are made by using premium quality materials and enhance technology at our vendors end. These are widely used in a variety of sectors. Our items are easily available at a very low market prices.

20 level C TO 80 level C
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 casing + coupling) provides great versatility to suit a broad selection of applications and higher efficiency compared to the compact range XC, where in fact the emphasis is on space performance.
Series H offers the same features since series X with an extra plus: a spur gear pre-stage at the input end provides higher overall performance and a good broader range of ratios than the X series.
Frame sizes 110 and 90 include a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is manufactured from casehardened and hardened alloy steel and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow output shaft comes as standard.
Broad range of options available:
second input, result flange, single or dual extension result shaft, torque limiter with through wire, torque arm.
