Worm gears are used when huge equipment reductions are gear motor for greenhouse needed. It’s quite common for worm gears to have reductions of 20:1, and actually up to 300:1 or greater.

Many worm gears have a fascinating property that no various other gear established has: the worm can easily turn the gear, however the gear cannot turn the worm. This is because the angle on the worm is so shallow that when the apparatus attempts to spin it, the friction between the gear and the worm holds the worm set up.

This feature pays to for machines such as for example conveyor systems, where the locking feature can become a brake for the conveyor when the motor is not turning. An added very interesting use of worm gears is in the Torsen differential, which is utilized on some high-performance vehicles.
