THREE-LINK SCREW-TYPE MECHANISM WITH TURNING AND SLIDING PAIRS

Link 1 is connected by turning pair A to the fixed link and by sliding pair B to link 2 which, in turn, is connected by screw pair C to the fixed link. Link 2 has a prismatic outside surface and internal thread. Rotation of link 1 is converted into screw motion of link 2. When link 1 is turned through the angle ϕ₁, the displacement of link 2 along axis y-y is s₂=h_C(ϕ₁/(2π)) where h_C is the pitch…
