Ever-Power worm gearboxes possess earned a popularity 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 flexibility accorded through a wide choice of mounting choices, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the market. 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.
Ever-Power Worm gearboxes provide high torque with low speed gear ratio. Being basic and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities are similar to helical gears, but its helix position is typically comparatively larger) and its body is normally quite lengthy in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting option include universal housing, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available 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 worm shaft and worm wheel. The worm can be shaped like a screw and the worm wheel is certainly a kind of gear machined to get a tooth profile with the same configuration.
The operation of a worm gear is similar with that of a bolt and nut. The principle is equivalent to a nut that has been fixed so that it cannot rotate and for that reason progresses in the axial direction when the bolt is certainly turned.
The design of a worm gear is considered through the relationship between the 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. For this reason, in a 1 speed reduction gears, the wheel could be manufactured so that it’ll be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally because of the structure. This characteristic makes it possible to layout the turning transmitting 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 change the rotation direction of the worm wheel by changing the screw path.
A multitude of shaft layouts The wide variety of shaft layouts is one of the top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Physique 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 certainly characteristic since the contact is certainly linear and the relative slide is excellent. In comparison to rolling power transmission, sound and vibration are extremely low. Because of this, this technology can be 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 maker catalogs and the series and models should be selected according to those procedures. Particular care should be taken in key areas such as for example selecting the load index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When using a worm reduction gears, heat produced through the initial period of make use of 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 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 per year according to the procedure manual supplied by the manufacturer.

The worm reduction gears come in two series: X and H.
The series X, featuring 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 suit a broad range of applications and provides higher efficiency compared to the compact collection XC, where the emphasis is on space effectiveness.
Series H supplies the same features as series X with an added plus: a spur gear pre-stage at the insight end provides higher overall performance and a broader selection of ratios compared to the X series.
Frame sizes 110 and 90 include a cast-iron housing cast Worm Reducer 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 has a cast iron hub with cast bronze insert. Hollow output shaft is supplied as standard.
Broad range of options available:
second input, output flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
