Worm Gears

A worm gear is a type of gear, engaging with a worm to significantly reduce rotational speed, or allowing higher torque to be transmitted. The gear can achieve a higher gear ratio than spur gears of the same size.

Materials Used
Worm gears can be constructed from a number of materials depending on the end application. Some of the popularly use materials are :

 

The gears can operate under difficult conditions and have the ability to achieve large speed reductions. The gears also transmit high loads at high speed ratios.
