摘要
在建立了形位公差国家标准之后,一般仍用尺寸公差或者用线轮廓度公差评定凸轮。用径向圆跳动公差评定凸轮的方法优于前两者,径向圆跳动公差更适合于凸轮的评定。径向圆跳动公差评定时,凸轮的误差(测量)值和公差(评定)值都要是径向值,便于测量、处理、评定,方法简便、直观。
After setting up of the geometric tolerance national standards (GB), the dimensional tolerances or dimensional tolerance assessment of profile of cam we,'e still used in general. It was believed that radial round beating tolerance assessment of the cam was better than the first two, and was much more suitable. At radial round beating tolerance assessment of the cam, runout cam error (measured) values and tolerances (assessment) should all be radial value. The method is simple ease of measurement, evaluation, and intuitive, dynamic in tolerance assesslnent,
