Working Principle of Linear Gear Rack
Components
Linear gear rack consists of a straight bar with teeth (the rack) and a rotating gear (the pinion).
Engagement
The pinion gear meshes with the teeth of the rack.
Motion Conversion
As the pinion rotates, it moves the rack linearly. The direction of the pinion’s rotation determines the movement direction of the rack.
Applications
Linear gear rack is used in systems where precise linear positioning is needed, such as CNC machines and automated systems.
