Worm Gear

  What is Worm gear ?

 A worm gear is a gear consisting of a shaft with a spiral thread that engages with and drives a toothed wheel. Worm gears are an old style of gear, and a version of one of the six simple machines. Basically, a worm gear is a screw butted up against what looks like a standard spur gear with slightly angled and curved teeth.

Where to use ?

1. Fast Braking and Stopping Applications – These gear motors are commonly used in lifts, elevators, and hoists. Worm gears are used in this equipment because of their stopping and holding ability without an external brake.
2. Noise Elimination for Gears – Worm gear motors are also used in theatres, airports, and elevators. They are commonly used in these industries because worm gear motors offer more quiet operation compared to other types of gears.
3. Space Saving Applications – Worm gears are also used in the manufacturing and packaging industries. They are used in packaging equipment, small machinery, and conveyors. They are ideal for these types of equipment because they have fewer gear sets which achieve high gear ratios.
4. Shock Loading Applications – Worm gear motors are designed to have one set of gear that is made of softer metals which give them the ability to easily absorb the energy from sudden shock.
