Link 1 rotates about axis x-x and is connected by screw pair A to link 3. Link 5 is of wedge shape and slides in fixed guide p. Through roller a, link 5 transmits motion to link 6 which slides in fixed guide q. Link 6 is set in the required position by turning adjusting link 1. When link 1 is turned, link 3 is displaced and, through link 4, actuates wedge 5. This transmits sliding motion to link 6 through roller a mounted on link 6. Clearance is eliminated in screw pair A by means of screws 2. This reduces the backlash of the mechanism.
