非圆齿轮误差测量方法分析

Study on the Measurement Method of Non-circular Gear Error

针对现有非圆齿轮测量方法较多的问题,提出了对比不同测量方法所得的测量精度以获得更高精度的测量方法.应用3种不同的测量方法测量同一非圆齿轮,通过对比相同误差项目的测量结果,研究不同测量方法的不同之处.结果表明:使用3种测量方法均可实现对非圆齿轮的测量,而采用三维扫描仪测量非圆齿轮的精度更高.

In view of the problems of existing non-circular gear measurement methods,a higher accuracy measurement method is proposed with comparing different measurement methods.Three different measurement methods are used to measure the same non-circular gear.By comparing the measurement results of the same error items,the differences of different measurement methods are studied.The results show that the three methods can be used to measure the non-circular gear,and the three-dimensional scanner is more accurate.
