Link 1 is connected by screw pair A to the fixed link and by turning pair B to link 2 which, in turn, is connected by sliding pair C to the fixed link. The element of sliding pair B belonging to link 2 is designed as a prismatic shank. Screw motion of link 1 is converted into sliding motion of link 2. When link 1 is turned through the angle ϕ₁, the displacement of link 2 along axis x-x is s₂=h_A(ϕ₁/(2π)) where h_A is the pitch of the thread of screw pair A. It is taken with a plus sign for right-hand thread and with a minus sign for left-hand thread.
