EP worm gearboxes possess earned a status to be a business benchmark worldwide. Our success came from our relentless get for quality with state-of-the-art technology, all and will be offering worm gearboxes will be affordable prices. High flexibility accorded through a broad choice of mounting choices, shaft configurations and motor interfaces, will make the EP worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating an extremely versatile drive system.
EP Worm gearboxes provide excessive torque with low speed gear ratio. Being simple and compact in design, these gears can achieve 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 path. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable 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 made up of a good worm shaft and worm wheel. The worm is definitely shaped such as a screw and the worm wheel is a type of gear machined to get 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 equivalent to a nut that is fixed so that it cannot rotate and therefore progresses in the axial path when the bolt is turned.
The design of a worm gear is thought of 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 simply by one tooth. Because of this, in a 1 speed reduction gears, the wheel can be manufactured so that it’ll be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This feature can help you layout the turning transmission direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could 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 wide variety of shaft layouts The wide variety of shaft layouts is among the features of interlocking gears.For example, right shaft output, 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, you’ll be able to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is characteristic since the contact is linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are extremely low. For this reason, this technology can be used to drive medical apparatus, elevators and escalators, etc.

Key points when selecting 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 should be selected according to those procedures. Particular care should be taken in essential areas such as selecting the load index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm lowering gears, 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 achieving the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to improve the lubricating oil and also to change the lubricating oil from then on about 1 time per 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, 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 range of applications and provides higher efficiency than the compact collection XC, where in fact the emphasis is on space performance.
Series H supplies the same features because series X with an added plus: a spur equipment pre-stage at the input end provides higher performance and a broader range of ratios compared to 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 is supplied as standard.
Broad range of possibilities:
second input, output flange, single or double extension result shaft, torque limiter with through cable connection, torque arm.
