Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our success originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High flexibility accorded through a broad choice of mounting options, shaft configurations and electric motor interfaces, makes the Ever-Power worm gearbox the default choice for the industry. The helical-worm and the double-worm edition, 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 acceleration gear ratio. Being simple and compact in style, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type characteristics act like helical gears, but its helix angle is typically comparatively bigger) and its body is generally quite long in the axial path. The gears in these gearboxes could be correct or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (single or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a kind of interlocking gear composed of a worm shaft and worm wheel. The worm is certainly shaped such as a screw and the worm wheel is a type 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 is fixed so that it cannot rotate and for that reason progresses in the axial path when the bolt is definitely turned.
The look of a worm gear is considered through the relationship between your 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 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 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 could 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 selection of shaft layouts is one of the top features of interlocking gears.For example, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Number 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 characteristic because the contact is linear and the relative slide is great. In comparison to rolling power transmission, sound and vibration are really low. Because of this, this technology can be used to drive medical devices, elevators and escalators, etc.

Key points when selecting a worm reduction gears
Selection
When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care ought to be taken in important 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 use is high and running-in procedure 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 decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to improve the lubricating oil and to change the lubricating oil from then on about 1 time each year according to the operation 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, is available in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) offers great versatility to match a broad selection of applications and provides higher efficiency than the compact range XC, where the emphasis is on space effectiveness.
Series H supplies the same features because series X with an added plus: a spur equipment pre-stage at the input end provides higher performance and a broader selection of ratios compared to the X series.
Body sizes 110 and 90 feature a cast-iron casing 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 includes 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 double extension result shaft, torque limiter with through cable, torque arm.
