About Rack and Pinion Gears

Rack and pinion gears are used to convert rotation into linear motion. The speed with which the rack moves as the pinion turns is determined by the diameter of the gear. The flat, toothed part is the rack and the gear is the pinion. A piston coaxial to the rack provides hydraulic assistance force, and an open centered rotary valve controls the assist level. A rack and pinion gears system is composed of two gears. The normal round gear is the pinion gear and the straight or flat gear is the rack. The rack has teeth cut into it and they mesh with the teeth of the pinion gear. Rack and pinion gears provide a less mechanical advantage than other mechanisms, but greater feedback and steering sensation.

Products & Services Related to Rack and Pinion Gears

Bevel and Miter Gears

Bevel and miter gears have conical faces that operate on intersecting axes. Miter gears are bevel gears with a 1:1 ratio operating on right axes.

Gears

Gears are mechanical devices that transmit power and motion between axes.

Helical Gears

Helical gears transmit power and motion between parallel axes (opposite hand) or right-angle axes (same-hand).

Hypoid Gears

Hypoid gears have specially formed teeth on a circular face that are driven by a worm-like drive on non-intersecting axes.

Metric Gears

Metric gears are defined by module, which designates the center-to-center distance between successive teeth.

Spur Gears

Spur gears are straight-toothed gears with radial teeth that transmit power and motion between parallel axes.

Worms and Worm Gears

Worm gears are cylindrical gears with a spiral thread that drive mating worm wheels in high-reduction gearset applications. They operate on non-intersecting perpendicular axes.
