For the outer sheave mechanism, if the driving dial with the round pin rotates continuously, when the round pin has not entered the groove of the sheave (to avoid axial force, it is usually opened in the radial direction), due to the concave groove in the sheave The locking arc mn is blocked by the convex circular arc locking arc mn of the dial, so the sheave does not move. When the round pin enters the groove, the locking arc is just released, and the dial drives the sheave to rotate. When the round pin leaves the radial groove from the other side, the locking arc is blocked again, and the sheave stops moving until the next round pin enters the groove. In this way, the one-way intermittent rotary motion is output circularly.

Working characteristics of Groove Pulley

The Groove Pulley mechanism is simple in structure, easy to process, reliable in operation, can accurately control the rotation angle, and has high mechanical efficiency. A sheave mechanism provides smoother movement into and out of engagement than a ratchet mechanism.
