简要介绍了一种新型的传动机构——曲柄群驱动机构。考虑到在高速运动过程中机构存在的振动问题,结合曲柄群机构的运动分布形式,采用“单元化动平衡”的方法来对曲柄群机构的动平衡问题进行研究。建立了曲柄群机构“单元化”模型以及对应的力学模型,完成了曲柄单元内动平衡的计算。 A brief introduction of a new type of transmission mechanism - crank group drive mechanism. Considering the vibration problems existing in the mechanism during the high-speed movement, the dynamic balance problem of the crank group mechanism is studied by the method of “unitized dynamic balance ” based on the motion distribution of the crank group mechanism. The crank group mechanism “unitized ” model and the corresponding mechanical model are established, and the calculation of dynamic balance in the crank unit is completed.
