screw gear

Screw gear is a common mechanical transmission element. Its gear tooth surface is spiral, similar to the shape of a spiral. The working principle of screw gear is to realize the functions of rotation transmission and force transmission through two screw gears that mesh with each other. The main characteristics of screw gear include spiral tooth surface, gradual contact during meshing, smooth transmission, low noise, and high efficiency. Screw gear usually consists of input gear, output gear, shaft, casing and other parts.
