Worm gear and worm drive worm gear and worm drive for two axial cross into *0 degrees, but are neither parallel nor intersect with each other, usually in the worm gear, worm is active, and worm gear is passive.Worm gear and worm drive has the following characteristics:
1) the structure is compact, and can get large transmission ratio, average ratio of ***0.
2) work smoothly without noise
3)Large range of transmission power
4)  can be self-locked.
5) transmission efficiency is low, worm gear often need non-ferrous metal manufacturing.The worm screw has a single head and long.

The calculation of transmission ratio is as follows:
I = n1/n2 = z/K
n*- the speed of the worm
n2 - worm gear speed
K -number of threads of worm
z-The number of teeth on the worm gear
