Crank 1 rotates about fixed axis A and is connected by turning pair B to link 2 which, in turn, is connected by screw pair D to link 3. Link 3 is connected by turning pair E to link 4 which turns about fixed axis C. The helix angle of the thread of screw pair D is greater than the angle of friction. When crank 1 rotates about axis A, link 3 oscillates about axis C and about its own axis z-z.
