Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success came 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 motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. The helical-worm and the double-worm version, with or without the torque limiter, add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to 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 can be right or left-handed depending upon the purpose.
Mounting choice include universal housing, part 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 worm shaft and worm wheel. The worm is shaped just like a screw and the worm wheel is definitely a kind of gear machined to get a tooth profile with the same configuration.
The operation of a worm gear is comparable with that of a bolt and nut. The principle is the same as a nut that is fixed so that it cannot rotate and for that reason 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
High 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 can be manufactured so that it will be rotated 1/60 (1/120 in particular applications).
Orthogonal shaft The shafts are aligned orthogonally because of 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). You’ll be able to change the rotation path of the worm wheel by changing the screw direction.
A multitude of shaft layouts The wide selection of shaft layouts is among the top features of interlocking gears.For example, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Figure 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 definitely characteristic because the contact can be linear and the relative slide is great. In comparison with rolling power transmission, sound and vibration are extremely low. Because of this, this technology is utilized to drive medical products, elevators and escalators, etc.

Key points when choosing 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 should be taken in crucial areas such as selecting the load index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm decrease gears, the heat produced during the initial period 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 reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to change the lubricating oil and to change the lubricating oil after that about 1 time each year according to the procedure manual supplied 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 match a broad selection of applications and provides higher efficiency than the compact line XC, where the emphasis is on space performance.
Series H offers the same features because series X with an added plus: a spur gear pre-stage at the insight end provides higher functionality 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 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 options available:
second input, result flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
