设计曲柄摇杆机构的辅助圆法

The assistant circle method of designing planar crank swaying rod mechanism

根据给定的行程速比系数K、摇杆的长度l3 及摇杆的摆角 ψ的基本原始设计数据 ,引入 3个辅助圆 ,成功解决了在附加约束条件—曲柄长度l1或连杆长度l2

By means of assistant circles,this paper solved the problem of designing planar crank pendulum pole mechanism on the condition of time ratio,the swaying rod length l 3 and the swaying rod angle ψ,addition with the crank length l 1 or the connecting rod length l 2.
