| Abstract: | Based on the theory of envelopes for 1 parameter family of surfaces to analyze spatial cam mechanisms is intuitive in geometry, high accurate and easily programming using computer. In this paper, the analytical profile expression of conical cam with oscillating conical roller follower is established once the follower motion program has been given. Further more. the analytical expression of pressure angles and principal curvatures are derived from the obtained analytical profile expression. The case demonstrates that results are correct and the proposed approach is favorable for building the CAD/CAM software of cam mechanisms. |
