Three-Stage Gear Set

The grinding wheel is parallel to the axis of the gear to be grinded. During grinding, the gear to be grinded drives the grinding wheel to perform free meshing action without backlash. After a period of time, the grinding wheel and the wheel to be ground are reversely rotated, so that the two sides of the teeth are evenly ground.
Because the sliding speed of the tooth surface is uneven, the grinding amount is also uneven, and the sliding speed of the tooth top and tooth root is large, and the grinding amount is also large.
