Gears and racks （https://www.cptc-china.com/gea....r-rack-and-pinion）ar commonly used mechanical transmission components that work together to transmit power. The working principle of a gear and rack system is based on the meshing of teeth. When a gear and rack engage, each tooth on the gear meshes with a corresponding tooth space on the rack, thereby transmitting power. By changing the rotational speed or direction of the gear, the movement speed and direction of the rack can be altered.
