Worm Drive Gearbox Brief Introduction and Model Selection

“Worm Gearbox” as a noun, is widely used in reducer industry development, worm drive gearbox is a major driving
structure in the industrial gearbox, in the gearbox development process. Worm gear reducer is transmission equipment for stable, change speed, it
using different gear ratios, in order to achieve stable transmission, change the speed, adjust the motor speed and
machine tools and other equipments get a suitable speed. In current transmission equipment, gearbox application is
very extensive, such as Vehicles on the truck, Ferries, aeroplanes; transmission equipment for machinery production, etc.
besides, watches, washing machines, etc in daily life appliances, these mechanical devices are assisted by gearbox

1, Worm gearbox main models:

Worm Gearbox Main Models Catalogue Download
RV series worm drive gearbox
WP series iron worm gearbox
JWG Series Helical Gear-Worm Gear Reducer
SCW (U, S, O) type shaft-mounted arc cylindrical reducer
SWL series Ball Screw Lifter

2, Worm Gearbox Model Selection
First of all, consider the role of the gearbox itself. Then transmission ratio, device mode,
assembly form. Finally, note that the corresponding motor power, and motor working environment.

3, Worm Gearbox Function
The gearbox can improve output torque when decrease output speed, the rate of output torque get from the motor
speed * ratio.
Decrease the inertia of the load while reducing the speed.

4, During processing spherical worm, easy to appear the questions as follows:
Worm shaft teeth are thick on one side, thin teeth on the other side meanwhile.
The worm tooth shape is thick on both sides, thin in the centre. Worm tooth shape on both sides of the thin, thick in the Middle.
Using the milling machine processing the worm, has the following advantages:
A) cost-saving tool.
Without special equipment. The disadvantage is obvious
(1) worm gear tooth indexing error is large.
(2) precision worm gear pressure angle can not be guaranteed.
(3) the worm tooth helix angle error is too large.
