The crankshaft is the main shaft of the compressor.
One side it is connected to the electric motor directly by the coupling or by the belt and pulley arrangement. The rotation of the motor shaft brings about the rotation of the crankshaft. On the other side, it is connected to the connecting rod, which is then connected to the piston at it’s other end.
The rotary motion of the crankshaft is converted into the reciprocating motion of the piston by connecting the rod.
