EP worm gearboxes have earned a status to be a business benchmark worldwide. Our success came from our relentless drive for top quality with state-of-the-art technology, all and will be offering worm gearboxes happen to be affordable prices. High flexibility accorded through a wide choice of mounting options, shaft configurations and motor interfaces, creates the EP worm gearbox the default decision for the industry. 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 excessive torque with low speed gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix position is typically comparatively bigger) and its own body is normally quite long in the axial path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (solitary or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a kind of interlocking gear made up of a good worm shaft and worm wheel. The worm is usually shaped just like a screw and the worm wheel is definitely a type of gear machined to have a tooth profile 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 direction when the bolt is certainly turned.
The look of a worm gear is considered 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. For this reason, in a 1 speed decrease gears, the wheel could be manufactured therefore that it will be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This characteristic can help you layout the turning transmission 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 path.
A multitude of shaft layouts The wide selection of shaft layouts is among the features of interlocking gears.For example, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Determine 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 because the contact is usually linear and the relative slide is excellent. In comparison to rolling power transmission, noise and vibration are extremely low. Because of this, this technology can be used to drive medical gear, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When choosing 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 for example selecting the strain index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm lowering gears, heat produced through the initial amount of use is high and running-in procedure at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key 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 furnished by the manufacturer.

The worm reduction gears can be found in two series: X and H.
The series X, having a worm and worm wheel set, comes 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 provides higher efficiency than the compact brand XC, where the emphasis is on space efficiency.
Series H supplies the same features as series X with an added plus: a spur equipment pre-stage at the input end provides higher performance and a broader range of ratios than the X series.
Frame sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes make use of 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 output shaft comes as standard.
Broad range of options available:
second input, result flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
