Synthesis of the Profile of Swing Link Cam in Swing Link Rack Transmission

This paper introduces a swing link rack transmission, which evolves from the sliding teeth drive, and its principle as well as the conditions of continuity of motion. The theoretical contour curve equation and the actual contour curve equation of two sides of swing link cam are deduced in the pole coordinate system respectively, and the equation based on two different pole coordinate system are consolidated into one in succession. At last, the discussion about the requisite qualification for the smooth transition between two profiles on swing link cam is presented, which provides a theoretical basis for the curve designing, machine operation and further research on such machine.
