Rack and Pinion for Machine Tool Applications
A rack and pinion is a type of steering mechanism that converts rotational motion into linear motion. It consists of a gear called a pinion, which is attached to the steering shaft, and a flat, toothed bar called a rack. When the pinion gear rotates, it engages with the rack, causing it to move in a linear direction. This linear motion is then translated into the turning motion of the vehicle’s wheels, allowing for steering control. The rack and pinion system is commonly used in automobiles and other vehicles for its efficiency and compact design.
