Racks and Pinions

Racks and Pinions are essentially a linear shaped variation of spur gears. The Spur rack is a portion of a spur gear with an infinite radius.The rack and pinion system is a widely-used power steering system. Its straightforward design can be implemented into most power steering systems. A ‘rack and pinion’ gears system looks quite unusual. However, it is still composed of two gears. The ‘pinion’ is the normal round gear and the ‘rack’ is straight or flat. The ‘rack’ has teeth cut in it and they mesh with the teeth of the pinion gear.
