Ever-Power worm gearboxes have earned a popularity to be a business benchmark worldwide. Our achievement 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 options, shaft configurations and 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 a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low velocity gear ratio. Being simple and compact in design, these gears can perform higher gear ratio than the helical gears. These worm decrease gears having screw type characteristics are similar to 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 can be right or left-handed dependant on the purpose.
Mounting choice include universal housing, part 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 kind of interlocking gear composed of a worm shaft and worm wheel. The worm is certainly shaped like a screw and the worm wheel is definitely 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 is fixed to ensure that it cannot rotate and for that reason progresses in the axial path when the bolt can be turned.
The look of a worm gear is thought of through the relationship between the 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 simply by one tooth. For this reason, in a 1 speed reduction 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 due to 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 can be clockwise or counterclockwise (generally clockwise). You’ll be able to change the rotation direction of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide variety of shaft layouts is one of the top features of interlocking gears.For instance, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a total of 14 types (Physique 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 certainly 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 utilized to drive medical devices, 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 manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care should be taken in key areas such as for example selecting the load index, calculating the overhang load and examining the heat rated capacity 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 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 operation (approximately 50 hours), it is necessary to change the lubricating oil and to change the lubricating oil after that 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, comes in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell housing + coupling) provides great versatility to suit a broad range of applications and higher efficiency than the compact series XC, where in fact the emphasis is on space effectiveness.
Series H offers the same features because series X with an extra plus: a spur equipment pre-stage at the input end provides higher performance and a broader range of ratios compared to the X series.
Framework sizes 110 and 90 feature a cast-iron housing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced from casehardened and hardened alloy metal 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 possibilities:
second input, result flange, single or double extension output shaft, torque limiter with through cable, torque arm.
