摘要：

The dynamic model of a new type of globoidal cam indexing mechanism with steel ball was established by use of Lagrange equation. In the modeling process, the mass of roller was neglected, and the contact stiffnesses between roller and cam and between roller and indexing plate were regarded as two stiffnesses in serial connection. According to the rotary transform tensor theory, the geometric displacement relation between generalized coordinates was analyzed. Dynamic equations of the mechanism considering torsion modulus were built, and the natural frequency and vibration mode of the transmission system were solved. The results show that the natural frequency varies with the variation of cam rotating angle at indexing period and is invariable at dull period, and the varying trends of natural frequencies of different orders are dissimilar.
