Understanding Rack and Pinion Actuators
Basic Mechanics
Rack and pinion actuators convert rotational motion into linear motion by utilizing a gear mechanism. The rack, a flat bar with teeth, moves linearly, while the pinion, a small gear, rotates. As the pinion turns, its teeth mesh with the rack’s, causing it to move. This simple yet effective design ensures smooth and precise motion in various applications.
Pros:
