Kinetostatic analysis of a new type of oscillating tooth indexing cam mechanism

Since the indexing speed of indexing mechanism fails to meet the higher requirements, a new type of indexing mechanism with the same axle and rotating speed of input/output was presented, the structure of which was borrowed from that of oscillating tooth of planetary gear transmission system. The ejector pins of the mechanism are symmetric, which is suitable for high-speed indexing transmission. The equations of the cam's pitch curve was deduced according to the formative principle of conjugate tooth contour. And then considering the inertia force, the dynamic model was established. With MATLAB programming, kinetostatic analysis of the mechanism was carried out to study the influence of parameters on acting force. The results provide theoretical basis for creative design of high-speed indexing mechanism, as well as reference for optimization of such high-speed indexing mechanism.
