EP worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, creates the EP worm gearbox the default decision for the industry. The helical-worm and the double-worm edition, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide high torque with low rate gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite lengthy in the axial direction. The gears in these gearboxes can 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 (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 is definitely shaped just like a screw and the worm wheel is a type of gear machined to get a tooth account 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 is fixed to ensure that it cannot rotate and therefore progresses in the axial path when the bolt is turned.
The design of a worm gear is considered through the relationship between the rack and spur gear on the middle plane of the worm wheel.
Features
Great reduction ratio One rotation of the worm rotates the worm wheel 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 special 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 transformation the rotation direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide selection of shaft layouts is one of the top features of interlocking gears.For instance, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., incorporate for a complete of 14 types (Body 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 certainly linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are extremely low. Because of this, this technology can be used to drive medical tools, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When selecting a worm reduction gears, the procedures for selecting the correct 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 load index, calculating the overhang load and examining the heat rated ability from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, the heat produced through the initial amount of use is large and running-in operation 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 reduction gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it’s important to change the lubricating oil and also to change the lubricating oil from then on 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, having 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 provides higher efficiency compared to the compact brand XC, where in fact the emphasis is on space performance.
Series H offers the same features since series X with an added plus: a spur gear pre-stage at the input end provides higher functionality and a broader selection of ratios compared to 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 produced from casehardened and hardened alloy steel and ground-finished.
The worm wheel includes a cast iron hub with cast bronze insert. Hollow output shaft comes as standard.
Broad range of possibilities:
second input, result flange, single or dual extension result shaft, torque limiter with through cable connection, torque arm.
