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

Link 1 is connected by turning pair A to the fixed link and by screw pair B to link 2 which, in turn, is connected by sliding pair C to the fixed link. Link 2 is designed as a rectangular block with internal screw thread. Rotation 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_B(ϕ₁/(2π)) where h_B…
