花键轴的等分累积误差,是评定花键轴质量的主要指标。因为它直接影响到花键轴的承载能力及其使用寿命,所以必须根据不同的工作情况将花键轴的等分累积误差限制在一定的范围内。目前花键轴的加工还是以切削加工为主。切削加工通常采用两种方法:一是滚 Spline shaft equal cumulative error is to assess the quality of splined shaft main indicators. Because it directly affects the bearing capacity of the spline shaft and its service life, it is necessary to limit the cumulative spline shaft error to a certain extent according to different working conditions. The current spline shaft machining or cutting-based. Cutting is usually used in two ways: First, roll
