Ever-Power worm gearboxes possess earned a status to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-art technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting choices, shaft configurations and 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 acceleration gear ratio. Being simple and compact in design, these gears can achieve higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite long in the axial direction. The gears in these gearboxes can be right 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 (single or double), 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 certainly 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 has been fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is turned.
The look of a worm gear is thought of through the relationship between the rack and spur gear on the middle 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 can be manufactured so that it’ll be rotated 1/60 (1/120 in unique 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 can be clockwise or counterclockwise (generally clockwise). It is possible to change the rotation direction of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide variety of shaft layouts is one of 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 (Body 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 usually characteristic since the contact is linear and the relative slide is fantastic. In comparison with rolling power transmission, noise and vibration are extremely low. For this reason, this technology is used to drive medical devices, 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 should be selected according to those procedures. Particular care should be taken in crucial areas such as for example selecting the strain index, calculating the overhang load and examining the heat rated capability from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, the heat produced through the initial period of make use of is high 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 is necessary to change the lubricating oil and to change the lubricating oil after that about 1 time per year according to the procedure manual provided by the manufacturer.

The worm reduction gears can be found 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) offers great versatility to match a broad selection of applications and higher efficiency than the compact collection XC, where the emphasis is on space performance.
Series H offers the same features because series X with an extra plus: a spur gear pre-stage at the input end provides higher functionality and a broader selection of ratios compared to the X series.
Body sizes 110 and 90 include 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 has a cast iron hub with cast bronze insert. Hollow output shaft is supplied as standard.
Broad range of possibilities:
second input, result flange, single or dual extension result shaft, torque limiter with through cable, torque arm.
