Ever-Power worm gearboxes have earned a status to be an industry benchmark worldwide. Our achievement originated from our relentless drive for quality with state-of-the-artwork technology, all while offering worm gearboxes are affordable prices. High versatility accorded through a broad choice of mounting choices, 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 an extremely Worm Reducer versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being basic and compact in design, these gears can achieve higher gear ratio than the helical gears. These worm reduction gears having screw type qualities act like 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 can be right or left-handed dependant on the purpose.
Mounting option include universal housing, aspect flanges, foot (horizontal and vertical), shaft mounted with torque arm. Obtainable in Solid shafts (single 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 shaped such as a screw and the worm wheel is usually a type of gear machined to have a tooth profile with the same configuration.
The operation of a worm gear is comparable with that of a bolt and nut. The principle is equivalent to a nut that has been fixed to ensure that it cannot rotate and for that reason progresses in the axial direction 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 middle plane of the worm wheel.
Features
High reduction ratio One rotation of the worm rotates the worm wheel by one tooth. Because of this, in a 1 speed decrease gears, the wheel can be manufactured so that it’ll be rotated 1/60 (1/120 in special applications).
Orthogonal shaft The shafts are aligned orthogonally due to the structure. This feature can help you 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 path of the worm wheel by changing the screw path.
A wide variety of shaft layouts The wide selection of shaft layouts is one of the top features of interlocking gears.For instance, right shaft output, remaining shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Shape 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 fantastic. In comparison with rolling power transmission, noise and vibration are extremely low. Because of this, this technology can be used to drive medical apparatus, 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 maker catalogs and the series and models should be selected according to those procedures. Particular care ought to be taken in crucial areas such as selecting the load index, calculating the overhang load and examining heat rated capacity from the manufacturer.
Cautions during use
When using a worm decrease gears, heat produced during 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 achieving the performance of the worm decrease gears.
Maintenance and inspection
After completing running-in procedure (approximately 50 hours), it is necessary to change the lubricating oil and to change the lubricating oil after that about 1 time per year according to the procedure 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) offers great versatility to suit a broad selection of applications and higher efficiency compared to the compact series XC, where in fact the emphasis is on space effectiveness.
Series H supplies the same features since 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.
Frame 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 manufactured from casehardened and hardened alloy metal and ground-finished.
The worm wheel has a cast iron hub with cast bronze insert. Hollow result shaft comes as standard.
Broad range of possibilities:
second input, result flange, single or dual extension output shaft, torque limiter with through cable, torque arm.
