本文讨论了键槽对称度误差的评定。介绍了 GB1958——80《形状和位置公差检测规定》中所推荐的测量方法,同时对该方法的局限性进行了分析,并提出了符合定位最小条件的轴键槽对称度误差的测量方法。
This article discusses the evaluation of keyway symmetry errors. The measurement method recommended in GB1958--80 “Provisions on the detection of shape and position tolerances” is introduced. At the same time, the limitations of this method are analyzed. A measurement method of the symmetry error of shaft keyways which meets the minimum positioning conditions is proposed.
