A worm gear system includes a worm and worm wheel. The worm resembles a screw, which meets with a worm wheel, as demonstrated in the picture. When rotational power is put on the worm, it rotates against the wheel and transfers power to the worm wheel. The machine is designed to ensure that the worm can simply turn the gear, however the gear cannot turn the worm. In some designs, the friction between the gear and worm keeps the worm in place. This feature can be quite useful in a few applications.
Worm gears will be the most compact type of system and provide high-ratio speed reduction. They are generally the preferred type of gearing program when space is bound and large equipment reductions are needed. Worm gears can be used to either greatly enhance torque or help reduce speed. Also, they are the smoothest and quietest of the gear systems, as long as they are properly mounted and worm and wheel steering gear lubricated.
Another advantage of worm gears is usually they have good meshing effectiveness. To be most effective, it is necessary 
that they are manufactured with high quality standards to ensure all gear requirements are precisely met.
