40Cr Steel Spur Gears Racks And Pinions For Automatic Door

Custom 40Cr Steel Spur Rack Gears And Pinions For Automotic Door Applications

1) Description of Rack Gear and Pinion

Rack and pinion is a type of linear actuator that comprises a circular gear /pinion engaging a linear

gear (the rack), which operate to translate rotational motion into linear motion. Driving the pinion into

rotation causes the rack to be driven linearly. Driving the rack linearly will cause the pinion to be

driven into a rotation. A rack and pinion drive can use both straight and helical gears.

2) Features of Rack Gear and Pinion

The rack carries the full load of the actuator directly and so the driving pinion is usually small,

so that the gear ratio reduces the torque required. This force, thus torque, may still be substantial

and so it is common for there to be a reduction gear immediately before this by either a gear or

worm gear reduction. Rack gears have a higher ratio, thus require a greater driving torque, than screw actuators.
