圆柱齿轮接触精度的评估和识别

Evaluation and Recognition of the Tooth Contact Accuracy for Cyindrical Gear

本文介绍了利用由三座标测量技术或齿轮全齿宽整体误差测量技术测得的齿面误差,通过计算机模拟轻载条件下齿轮副啮合过程的接触状态,用以评估轮齿的接触斑点。同时提出了应用模式识别技术自动识别轮齿接触斑点位置的方法。实验结果表明该法对于自动化生产齿轮加工精度的评估,齿轮副装配时的选配有着重要意义。

In this paper is proposed a technique of computer simulation to simulate the contact marking of gear pair under light load by means of tooth flank error of gears for evaluating the gear contact accuracy,and is proposedthe technique of computer pattern recognition for recognizing the locatio ofgear contact marking.The results of testing have shown that the above-mentioned methodes are effective to evaluate the manufacturing accuracy inautomatic production of gear and to select the gear pair in assembly.
