Ever-Power worm gearboxes have earned a reputation to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all and will be offering worm gearboxes are inexpensive prices. High flexibility accorded through a wide choice of mounting options, 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, add up to the advantage, creating an extremely versatile drive system.
Ever-Power Worm gearboxes provide high torque with low acceleration 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 are similar to helical gears, but its helix position is typically comparatively bigger) and its body is generally quite lengthy in the axial path. The gears in these gearboxes could be right or left-handed depending upon the purpose.
Mounting choice include universal housing, side flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or double), 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 usually shaped such as a screw and the worm wheel can be a kind 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 so that it cannot rotate and therefore progresses in the axial direction when the bolt is usually turned.
The design of a worm gear is considered 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 by one tooth. Due to this, in a 1 speed reduction 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 characteristic makes it possible to layout the turning transmitting direction at the right angle.
The arbitrariness of the rotation direction The screw direction of the worm could 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 features of interlocking gears.For instance, right shaft output, still left 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, you’ll be able to select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is definitely characteristic because the contact is linear and the relative slide is excellent. In comparison to rolling power transmission, noise and vibration are really low. Because of this, this technology is used to drive medical gear, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When choosing a worm reduction gears, the procedures for selecting the correct 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 for example selecting the strain index, calculating the overhang load and examining heat rated capability from the manufacturer.
Cautions during use
When using a worm decrease gears, heat produced through the initial period of use 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 attaining 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 also to change the lubricating oil after that about 1 time per year according to the operation 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, 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 range of applications and higher efficiency than the compact range XC, where in fact the emphasis is on space effectiveness.
Series H supplies the same features as 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.
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 includes a cast iron hub with cast bronze insert. Hollow result 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.
