Worm Gears

Worm gears are used when huge gear reductions are needed. It is common for worm gears to possess reductions of 20:1, and even up to 300:1 or greater.

Many worm gears have a fascinating property that no other gear arranged has: the worm can simply turn the gear, however the gear cannot turn the worm. That is China Pulley because the angle on the worm is indeed shallow that when the gear attempts to spin it, the friction between your equipment and the worm retains the worm set up.

This feature pays to for machines such as for example conveyor systems, in which the locking feature can become a brake for the conveyor when the motor isn’t turning. One other very interesting usage of worm gears is certainly in the Torsen differential, which is used on some high-performance cars and trucks.
