Ever-Power worm gearboxes have earned a status 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 flexibility accorded through a wide choice of mounting choices, shaft configurations and engine interfaces, makes the Ever-Power worm gearbox the default choice for the industry. 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 quickness gear ratio. Being simple and compact in design, 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 angle is typically comparatively bigger) and its body is normally quite lengthy in the axial direction. The gears in these gearboxes can be correct or left-handed dependant on the purpose.
Mounting choice include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (one or double), 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 is shaped just like a screw and the worm wheel is usually a kind of gear machined to get 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 the same as a nut that has been fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt can be turned.
The design 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. Due to this, in a 1 speed decrease 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 feature makes it possible to layout the turning transmitting direction at a right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible 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 among the features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Figure 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 certainly characteristic because the contact is linear and the relative slide is great. In comparison to rolling power transmission, sound and vibration are extremely low. For this reason, this technology can be used to drive medical gear, 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 key areas such as for example selecting the strain index, calculating the overhang load and examining heat rated capacity from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, 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 attaining the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it’s important to improve the lubricating oil and to change the lubricating oil from then on about 1 time each year according to the operation manual provided 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, is available 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 higher efficiency compared to the compact line XC, where the emphasis is on space performance.
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 range of ratios compared to the X series.
Framework sizes 110 and 90 feature a cast-iron casing 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 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.
