曲柄群驱动机构曲柄单元的动平衡研究

Abstract

A new type of transmission mechanism——crank-group driving mechanism is introduced.Taking into account the vibration problems of the mechanism in the process of high speed,and combining with the movement distribution form of crank-group mechanism,and adopting the unitary dynamic balance method,the problem of dynamic balancing the crank-group mechanism is studied.The crank-group mechanism unitary model and the corresponding mechanical model are established,and the calculation of dynamic balance in crank unit is finished.
