Ever-Power worm gearboxes possess earned a popularity to be an industry benchmark worldwide. Our success came from our relentless drive for quality with state-of-the-art technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad 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 version, with or without the torque limiter, soon 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 style, these gears can achieve higher gear ratio than 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 body is normally quite long in the axial path. The gears in these gearboxes could be correct or left-handed depending upon the purpose.
Mounting option 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 type of interlocking gear composed of a worm shaft and worm wheel. The worm is shaped just like a screw and the worm wheel is usually a type of gear machined to have 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 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 certainly turned.
The look 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 by one tooth. For this reason, in a 1 speed reduction gears, the wheel could be manufactured therefore that it will 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 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 path.
A multitude of shaft layouts The wide selection of shaft layouts is one of the top features of interlocking gears.For example, right shaft output, still left shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Body 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 usually characteristic since the contact is certainly linear and the relative slide is excellent. In comparison to rolling power transmission, noise and vibration are extremely low. For this reason, this technology is utilized 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 right gear are described in the manufacturer catalogs and the series and models should be selected according to those procedures. Particular care should be taken in important areas such as selecting the load index, calculating the overhang load and examining heat rated capacity from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, the heat produced during 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 key to sufficiently attaining 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 each year according to the procedure manual offered by the manufacturer.

The worm reduction gears come in two series: X and H.
The series X, having a worm and worm wheel set, is available 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 compared to the compact line XC, where the emphasis is on space efficiency.
Series H supplies the same features because series X with an extra plus: a spur gear pre-stage at the insight end provides higher efficiency and a broader selection of ratios compared to the X series.
Framework sizes 110 and 90 include a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced 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 possibilities:
second input, output flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
