滚子摆动从动杆盘状凸轮机构在工业中应用很广,长期以来都认为这种凸轮机构也与直动从动杆盘状凸轮机构一样,其压力角必随基园半径增大而减小,并由此得出设计方法。本文用具体数据和有关公式证明了上述结论的局限性,提出了衡量该种凸轮机构最小尺寸的正确观点,并由此得出正确的设计方法和编制出可行的设计程序。 Roller swing follower disc cam mechanism is widely used in industry, for a long time that this cam mechanism with the linear motion follower disc cam mechanism, the pressure angle with the base radius will increase and decrease Small, and derived from the design method. In this paper, the limitations of the above conclusions are proved by the concrete data and the related formulas. The correct viewpoint of measuring the minimum size of the cam mechanism is put forward, and the correct design method and the feasible design procedure are obtained.
