汽车差速器十字轴的加工误差分析

摘要

Every shaft dimensional tolerance ,four shafts flatness tolerance ,two group shafts vertical tolerance are should be en-sured in machining crass-axis.The traditional four clamping is adopted in machining crass-axis;flatness tolerance and vertical tol-erance are out of tolerance seriously .Improvement measures are put forward for these questions .%十字轴在加工过程中，既要保证十字轴每个轴头的尺寸，又要保证四轴的平面度，还要保证相互垂直的两组轴的垂直度。采用传统的四次装夹方式加工十字轴，平面度和垂直度都出现比较严重的超差现象。针对此问题，提出改进工艺措施。
