发布时间：2018-11-07 12:54
【摘要】：确定齿轮整体误差曲线上齿廓评价区域的准确位置是影响整体误差测量精度的关键问题,也是几十年来困扰整体误差推广的难题。提出应当区分整体误差单元曲线上不同阶段数据的可信度,在此基础上提出一种以啮出阶段数据为主确定齿廓评价区域的新方法。为验证新方法的正确性和有效性,进行标准齿轮和产品齿轮在不同转速下的测量试验,对比分析了由三种不同方法获取的单元起点位置的一致性。试验数据表明新方法得到的单元起点位置一致性较好,可满足汽车齿轮快速测量的要求,尤其在测量产品齿轮时,新方法的效果优于传统的互相关函数法。
[Abstract]:It is a key problem to determine the accurate position of the tooth profile evaluation area on the overall error curve of gears which affects the measuring accuracy of the whole error and is also a difficult problem that puzzles the generalization of the overall error in recent decades. It is suggested that the reliability of the data in different stages on the integral error unit curve should be distinguished. On this basis, a new method for determining the evaluation region of tooth profile is proposed. In order to verify the correctness and validity of the new method, the measurement experiments of standard gears and product gears at different rotational speeds were carried out, and the consistency of the starting positions of the units obtained by three different methods was compared and analyzed. The experimental data show that the new method has a good consistency of the starting point position of the unit and can meet the requirements of rapid measurement of automotive gears. Especially in measuring product gears, the effect of the new method is better than that of the traditional cross-correlation function method.
