渐开线花键轴冷滚轧工艺试验

根据啮合原理,运用等升距螺旋面的形成理论设计了滚轧轮理论廓形,采用试验计算法对滚轧轮的理论廓形进行修正;对滚轧轮的材料选择、热处理工艺进行了输入的研究,根据修正后的滚轧轮廓形制造出滚轧轮;进行了渐开线花键轴冷滚轧工艺等方面的研究,设计了冷滚轧渐开线花键轴的数控程序,进行了实际零件加工试验。结果证明:这套从滚轧轮设计、材料选择、制造到渐开线花键轴加工工艺设计理论的正确性。为自主设计制造冷滚轧滚轧轮提供了可行的方案,为冷滚轧渐开线花键轴提供了加工工艺规范。

Technologic Research on Rolling Involute Spline Axis

Based on meshing theory, the academic outline of roller on the principle of equal pitch helicoids was designs. And the amended method was introduced by the experimental data. The material and the method of heat treatment for roller have been discussed and the roller was made based on the corrected data. The cold rolling technology has been researched and the NC programm was made for trial producing of involute spline shaft. The roller design theory, material choice, manufacturing scheme and the technology theory for involute spline shaft has been proved to be correct. The feasibility project for roller independent manufacturing and the proper manufacturing technology for involute spline were introduced.
