Slider Crank Quick Return Mechanism SQI

Description

Slider crank Quick return mechanism is used to convert linear to rotary motion or vice versa. It is also used in applications requiring different forward and return stroke velocities. The crank slider quick return mechanism is used in metal shaper machines where the forward stroke is slow cutting stroke and the return stroke is fast idle stroke (no work is done by the tool). Large time ratio can be obtained using slider crank quick return mechanism. By moving the pivot “O” along the line AB, desired time ratio (α/β), between the forward and return stroke can be achieved.
