EP worm gearboxes have earned a reputation to be a business benchmark worldwide. Our success came from our relentless travel for top quality with state-of-the-art technology, all while offering worm gearboxes are 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 choice for the market. 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 large torque with low rate gear ratio. Being simple and compact in style, 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 position is typically comparatively bigger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (one or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear made up of a good worm shaft and worm wheel. The worm can be shaped such as a screw and the worm wheel can be a kind of gear machined to get a tooth profile with the same configuration.
The operation of a worm gear is similar 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 path when the bolt is definitely turned.
The design of a worm gear is thought of through the relationship between the rack and spur gear on the center plane of the worm wheel.
Features
Excessive reduction ratio One rotation of the worm rotates the worm wheel simply by one tooth. Because of this, in a 1 speed decrease gears, the wheel could be manufactured hence that it’ll 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 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 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 example, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., incorporate for a total of 14 types (Shape 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 characteristic because the contact is definitely linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are extremely low. Because of this, this technology is utilized to drive medical equipment, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When choosing 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 for example selecting the strain index, calculating the overhang load and examining heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm lowering 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 paramount to sufficiently attaining 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 procedure manual given 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 housing + coupling) provides great versatility to match a broad selection of applications and provides higher efficiency compared to the compact series XC, where in fact the emphasis is on space efficiency.
Series H offers the same features since series X with an added plus: a spur equipment pre-stage at the insight end provides higher overall performance and a broader selection of ratios than 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 steel 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 result shaft, torque limiter with through cable, torque arm.
