Link 1 turns about fixed axis A and has gear segment a with helical teeth which mesh with helical teeth of pinion 3. Pinion 3 is keyed to (or integral with) shaft 4 which rotates about fixed axis B-B. Shaft 4 is connected by screw pair D to the base. The face width of gear 3 is greater than that of helical gear segment a. When driving link 1 oscillates, driven shaft 4, in addition to its rotation about axis B-B, reciprocates along this axis.
