EP worm gearboxes possess earned a status to be an industry benchmark worldwide. Our success came from our relentless get for quality with state-of-the-art technology, all while offering worm gearboxes will be affordable prices. High versatility accorded through a wide choice of mounting choices, shaft configurations and motor interfaces, makes 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 a highly versatile drive system.
EP Worm gearboxes provide excessive torque with low swiftness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio than the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite long in the axial direction. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single 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 is shaped just like a screw and the worm wheel can be a type of gear machined to own a tooth profile 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 has been fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The design 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 simply by one tooth. Due to this, in a 1 speed decrease gears, the wheel could be manufactured therefore that it’ll be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature can help you layout the turning transmitting direction at a 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 change the rotation path of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For instance, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., incorporate for a total 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 usually characteristic since the contact is usually linear and the relative slide is excellent. In comparison with rolling power transmission, sound and vibration are extremely low. Because of this, this technology can be 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 manufacturer catalogs and the series and models should be selected according to those procedures. Particular care should be taken in important areas such as for example selecting the load index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm lowering gears, heat produced during the initial period of use is large and running-in operation at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key 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 also to change the lubricating oil after that about 1 time each year according to the procedure manual furnished 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) provides great versatility to match a broad range of applications and higher efficiency than the compact series XC, where the emphasis is on space effectiveness.
Series H supplies 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 broader range of ratios than the X series.
Body sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced 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 dual extension output shaft, torque limiter with through wire, torque arm.
