众所周知,曲柄连杆机构在其行程始端和终端的加速度、惯性很大,因而容易引起振动冲击,严重时甚至导致构件损坏,本文介绍一种外摆线运动行星齿轮和曲柄连杆机构的组合机构,这种机构克服了曲柄连杆机构的上述不足,它在行程的两端加速度和惯性为零,因此,适用于大型构件的传送工作,如组合机床自动线随行夹具的传送工 As we all know, the crankshaft and connecting rod mechanism at the beginning and end of its stroke acceleration, large inertia, and thus easily lead to vibration impact, serious or even cause damage to the components, this article describes a cycloid planetary gear crank and the linkage mechanism , This mechanism overcomes the above deficiencies of the crank and connecting rod mechanism. It has zero acceleration and inertia at both ends of the stroke. Therefore, it is suitable for the transmission of large-sized components such as the conveyor
