Identification

☞ The rack is identified by item number and order code as well as the manufacturer’s

logo. This identification also ensures the retraceablitiy of the manufacturing process.

Description

Rack and pinion drives convert the rotary motion and torque of a gearwheel into the power-

transmitting linear motion of a toothed rack. This takes place when the operating pitch

cylinder of the gearwheel meshes with the common pitch surface of the rack without

slipping. The rolling axis is thus the instantaneous axis of motion of the gearwheel in

relation to the rack. In rack and pinion drives the motion is transmitted by positive

connection. The teeth are therefore shaped in such a way that imaginary pitch cylinders can

be inscribed in both functional partners rolling on one another without slipping. At the point
