在一些力学和机械零件的书籍中,推荐用当量直径的等径轴作阶梯轴的变形计算来校核轴的刚度。在机床行业中,已采用当量直径法校核传动轴的刚度[4]。现从理论分析和典型的轴的误差计算,说明当量直径法存在着工程计算所不允许的误差。 当量直径法是把阶梯轴简化为当量直径的等径轴
In some mechanical and mechanical parts of the book, it is recommended to use the equivalent diameter of the isoaxial shaft for the deformation of the ladder shaft to check the stiffness of the shaft. In the machine tool industry, the equivalent diameter method has been used to check the stiffness of the transmission shaft [4]. From the theoretical analysis and the typical calculation of the shaft error, it shows that the equivalent diameter method does not allow the engineering calculation error. The equivalent diameter method is to simplify the ladder shaft equivalent diameter diameter shaft
