Ever-Power worm gearboxes possess earned a status 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 broad choice of mounting choices, shaft configurations and motor 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low speed gear ratio. Being basic 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 position is typically comparatively bigger) and its own body is generally quite long in the axial path. 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. Obtainable in Solid shafts (solitary 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 certainly shaped just like a screw and the worm wheel can be a type of gear machined to possess 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 to ensure 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 thought of 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. Due to this, in a 1 speed decrease gears, the wheel can be manufactured therefore 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 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 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 features of interlocking gears.For example, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Determine 2) and, if attachment orientations are included, you’ll be able to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is usually characteristic because the contact is usually linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are extremely low. For this reason, this technology is utilized to drive medical devices, elevators and escalators, etc.

Key points when selecting 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 essential areas such as 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, 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 key to sufficiently attaining the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it’s important to change the lubricating oil and to change the lubricating oil from then on about 1 time per year according to the operation manual provided by the manufacturer.

The worm reduction gears come in two series: X and H.
The series X, having 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 suit a broad selection of applications and provides higher efficiency than the compact range XC, where in fact the emphasis is on space efficiency.
Series H offers the same features because series X with an added plus: a spur gear pre-stage at the input end provides higher efficiency and a broader range of ratios than the X series.
Body sizes 110 and 90 include a cast-iron housing cast enbloc, whereas smaller sizes make use of 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 comes as standard.
Broad range of options available:
second input, output flange, single or double extension output shaft, torque limiter with through cable, torque arm.
