Gear Racks

Gear racks are toothed rails that turn rotation into linear motion. Their evenly spaced teeth interlock with the compatible teeth of a gear attached to a motor. As the gear rotates, it drives the gear rack's linear motion. Standard gear racks have straight teeth and are used with spur gears. Helical gear racks have angled teeth that gradually engage a helical gear's teeth, producing smoother, more efficient linear motion. Gear racks are commonly used in steering because they carry heavy loads, reduce backlash, and produce greater feedback than other steering mechanisms.
