aft and worm wheel. The worm can be shaped just like a screw and the worm wheel is certainly a type 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 equivalent to a nut that is fixed to ensure that it cannot rotate and therefore progresses in the axial path when the bolt is certainly 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. Due to this, in a 1 speed decrease gears, the wheel can be manufactured therefore 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 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 direction.
A multitude of shaft layouts The wide selection 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 total of 14 types (Worm Reducer Determine 2) and, if attachment orientations are included, it is possible to pick from over 40 layouts.
Low noise, low vibration The interlocking of the worm and worm wheel is characteristic since the contact is certainly linear and the relative slide is excellent. In comparison with rolling power transmission, noise and vibration are extremely low. For this reason, this technology is utilized 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 should be taken in important 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 utilizing a worm reduction 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 key to sufficiently attaining the performance of the worm reduction 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, featuring a worm and worm wheel set, is available in versions XA with shaft and XF-XC with mounting provisions for motor.
Version XF (bell casing + coupling) offers great versatility to suit a broad selection of applications and higher efficiency than the compact range XC, where the emphasis is on space efficiency.
Series H supplies the same features since series X with an added plus: a spur equipment pre-stage at the insight end provides higher efficiency and a broader range of ratios than the X series.
Body sizes 110 and 90 feature a cast-iron casing cast enbloc, whereas smaller sizes use die-cast aluminium housings. The worm shaft is produced 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 possibilities:
second input, result flange, single or double extension output shaft, torque limiter with through cable, torque arm.
