Worm Gears
A worm gear is a worm wheel module that combines a worm and a worm wheel, or a screw-like component that receives a worm wheel. The worm gear side also has slanted teeth that engage and rotate. It is possible to use up to 1/100 speed ratio and easy to set the backlash arbitrarily. It is built in when you want to adjust the gear speed mainly in the deceleration direction. There are various types and types depending on the shape of the component worm and worm wheel.
