空间角向孔作为行星轮系旋转作动器中的重要结构特征具有很高的加工精度。镗削时必须根据图纸设计尺寸得到准确的镗削工艺尺寸,以便准确定位。文章系统地对双角度、三角度空间角向孔镗削过程、工艺尺寸转换进行了研究,使用图解法、解析法推导出对应的计算公式,拓展了工艺尺寸转换方法。利用解析法得到的计算公式,实现利用空间角向孔与工艺钢球相对尺寸及空间角向孔角度尺寸,得到所需的镗削工艺尺寸,降低了工艺尺寸转换难度,提高了空间角向孔的镗削效率。同时结合Python编程语言,编写出一套工艺尺寸计算软件,验证了推导公式的有效性和准确性。

The precise machining of space angular holes is crucial for ensuring the structural integrity of planetary gear systems.Accurate machining dimensions are required to achieve precise positioning during the boring process,based on the design dimensions provided in the engineering drawings.The process of boring space angular holes with double and triple angles are studied systematically,along with the conversion of process dimensions.The calculation formulas is derived by means of graphic method and analytical method,expanding the range of methods available for converting process dimensions.By employing the derived analytical formulas,the required machining dimensions can be obtained by using the relative dimensions of the space angular hole and the process steel ball,and the angle dimensions of the space angular hole.To validate the effectiveness and accuracy of the derived formulas,a dedicated software tool is developed using the Python programming language,providing a practical implementation of the process dimension calculations.
