Design and function of a gear motor

Gear motors consist of two gear wheels, that run in a housing with minimal play. One gear wheel is rigidly interconnected with the drift shaft, the other generates the torque. Two gear flats are directed with compressed air into the turn direction and one gear flat against the turn direction. The exhaust air is directed into chambers which are formed between the gear flat and housing wall towards the exhaust air side and rotation is generated. Gear motors are operated oilfree.
