Ever-Power worm gearboxes have earned a popularity to be an industry benchmark worldwide. Our success 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 wide choice of mounting choices, shaft configurations and motor interfaces, makes the Ever-Power worm gearbox the default choice for the sector. 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 basic and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm decrease gears having screw type qualities act like helical gears, but its helix angle is typically comparatively larger) and its own body is generally quite long in the axial direction. The gears in these gearboxes can be correct 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 (single 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 can be shaped just like a screw and the worm wheel is definitely a type of gear machined to possess a tooth profile with the same configuration.
The procedure of a worm gear is similar 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 direction when the bolt is usually 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 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 because of 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 could be clockwise or counterclockwise (generally clockwise). You’ll be able to change the rotation direction of the worm wheel by changing the screw direction.
A wide variety of shaft layouts The wide variety of shaft layouts is one of the features of interlocking gears.For example, right shaft output, still 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 select from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is usually characteristic since the contact is definitely linear and the relative slide is fantastic. In comparison to rolling power transmission, sound and vibration are really low. Because of this, this technology is used to drive medical products, elevators and escalators, etc.

Key points when choosing a worm reduction gears
Selection
When selecting a worm reduction gears, the procedures for selecting the right gear are described in the manufacturer catalogs and the series and models should 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 heat rated capacity from the manufacturer.
Cautions during use
When utilizing a worm decrease gears, 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 paramount to sufficiently achieving the performance of the worm reduction gears.
Maintenance and inspection
After completing running-in operation (approximately 50 hours), it is necessary to improve 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 can be found in two series: X and H.
The series X, having a worm and worm wheel set, is available 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 range of applications and provides higher efficiency than the compact series XC, where the emphasis is on space performance.
Series H offers 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 range of ratios than the X series.
Frame sizes 110 and 90 include 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 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.
