曲柄摇杆机构在给定[γ]时K的最大值计算公式

The Calculation Formula of the Maximum Value of K in the Crank and Rocker Mechanism at a Given Fixed Value of

在文献[1]的基础上,导出了具有急回特性的曲柄摇杆机构在给定最小传动角许用值[γ]时行程速比系数最大值Kmax的计算公式,不需进行迭代优化就能算出,为综合曲柄摇杆机构选定K值范围提供了简捷准确的计算方法。

Based on literature,this article has deduced the calculation formula of the maximum value K_(max) of travel speed ratio coefficient in the crank and rocker mechanism with the characteristic of the swift-return movement,when a given minimum driving angle value of is allowed. Without iteration for optimum,this formula provides a fast and accurate calculation for the selection of K when crank and rocker mechanisms are designed.
