EP worm gearboxes possess earned a reputation to be a business benchmark worldwide. Our achievement came from our relentless travel for top quality with state-of-the-art technology, all while offering worm gearboxes happen to 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 sector. The helical-worm and the double-worm edition, with or without the torque limiter, soon add up to the advantage, creating a highly versatile drive system.
EP Worm gearboxes provide substantial torque with low velocity gear ratio. Being simple and compact in style, these gears can achieve higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite lengthy in the axial direction. The gears in these gearboxes can 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 (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 shaped like a screw and the worm wheel is a kind of gear machined to have 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 the same as a nut that has been fixed to ensure that it cannot rotate and therefore progresses in the axial direction when the bolt is definitely turned.
The look of a worm gear is considered through the relationship between your rack and spur gear on the center plane of the worm wheel.
Features
High reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed reduction gears, the wheel could be manufactured consequently that it will be rotated 1/60 (1/120 in unique applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This characteristic can help you layout the turning tranny direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm can be clockwise or counterclockwise (generally clockwise). It is possible to transformation the rotation direction of the worm wheel by changing the screw direction.
A multitude 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 complete of 14 types (Shape 2) and, if attachment orientations are included, it is possible 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 great. In comparison with rolling power transmission, noise and vibration are really low. Because of this, this technology is used 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 ought to 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 heat rated potential 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 operation 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’s important to improve the lubricating oil and to change the lubricating oil from then on about 1 time per year according to the operation 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) offers great versatility to suit a broad range of applications and provides higher efficiency compared to the compact brand XC, where in fact the emphasis is on space effectiveness.
Series H offers the same features since series X with an added plus: a spur gear pre-stage at the input end provides higher performance and a good broader range of ratios compared to the X series.
Framework 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 has a cast iron hub with cast bronze insert. Hollow result shaft is supplied as standard.
Broad range of options available:
second input, result flange, single or dual extension output shaft, torque limiter with through cable connection, torque arm.
