WORM DRIVE

A worm drive reduces the speed of a rotary system very effectively. The worm drive has two parts: a worm shaft and a worm gear.
The shaft had two, three or even more grooves. Each groove interlocks with one tooth of the worm gear.
When the worm shaft makes a rotation, the worm gear moves forward one tooth for every groove of the shaft.
