Ever-Power worm gearboxes possess earned a reputation to be an industry benchmark worldwide. Our success came 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 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, soon add up to the advantage, creating a highly versatile drive system.
Ever-Power Worm gearboxes provide high torque with low swiftness gear ratio. Being basic and compact in design, these gears can perform higher gear ratio compared to the helical gears. These worm reduction gears having screw type characteristics are similar to helical gears, but its helix angle is typically comparatively larger) and its own body is normally 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, part flanges, foot (horizontal and vertical), shaft mounted with torque arm. Available in Solid shafts (solitary or dual), with torque arm or torque limiter.
Worm reduction gears features
Principles
A worm gear is a type of interlocking gear made up of a worm shaft and worm wheel. The worm is shaped like a screw and the worm wheel is usually a type of gear machined to possess 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 has been fixed to ensure that it cannot rotate and for that reason 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 center 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 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 because of the structure. This characteristic makes it possible to layout the turning transmission direction at a right angle.
The arbitrariness of the rotation direction The screw direction of the worm could be clockwise or counterclockwise (generally clockwise). It is possible 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 features of interlocking gears.For instance, right shaft output, left shaft output, dual shaft input and dual shaft output, etc., combine for a complete of 14 types (Figure 2) and, if attachment orientations are included, you’ll be able to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is usually characteristic because the contact is definitely linear and the relative slide is great. In comparison with rolling power transmission, noise and vibration are really low. For this reason, this technology is used to drive medical apparatus, 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 manufacturer catalogs and the series and models ought to be selected according to those procedures. Particular care should be taken in essential areas such as selecting the load index, calculating the overhang load and Worm Reducer examining the heat rated capacity from the manufacturer.
Cautions during use
When using a worm reduction gears, the 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 attaining the performance of the worm decrease 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 from then on 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 compared to the compact range XC, where 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 insight end provides higher performance and a broader range of ratios than the X series.
Frame sizes 110 and 90 include a cast-iron housing 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 has a cast iron hub with cast bronze insert. Hollow result 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.
