The rack and pinion actuator is ideal for the highest demands on torque. It permits extensive swivelling where there is restricted building room in an axial direction. Additional options are as numerous as for the helical principle. The rack and pinion actuator requires considerably larger dimensions compared with the rotary vane motor to transfer two torques of equal size. This is created and transferred through a rack and pinion piston located diagonally to the propelling tappet developed with a pinion. The lateral forces arising from the teeth and affecting the back of the piston opposite are counterbalanced hydraulically or supported by rolling bearings depending on design. This rotary actuator is particularly suitable for high torque.
Actuators operating on this principle are used in cement factories, in the tyre industry, in power stations, in the steel industry and in rudder movement, for example.
