摘要
由于在齿轮副的最佳啮合位置处测量齿轮副的单面啮合可精确得到锥齿轮副的传动误差,本文研究了锥齿轮副最佳安装距的调整方法,并开发了相应的传动误差测控软件。介绍了在最佳安装距位置对锥齿轮副进行单面啮合测量的原理,描述了通过传动误差分析、频谱分析和精度等级评定对传动误差进行评定的方法。利用统计过程控制(SPC)法对锥齿轮副的切向综合总偏差和一齿切向综合偏差进行了工艺评定和过程监控。然后,设计了基于最佳安装距的锥齿轮副传动误差测控软件,完成了对传动误差的实时采集、数据处理和曲线显示,最佳安装距的寻优调整以及测量结果的SPC统计分析。给出了测控软件的类图、顺序图、测试用例和软件界面。最后,实验测量了一对齿轮副在安装距寻优调整前后的传动误差。结果显示,提出的方法和传动误差测控软件可应用于锥齿轮副或面齿轮副的测量。
Abstract
The transmission error of a bevel gear pair can be obtained when its single flank engagement is measured at the best mounting position. This paper explores an algorithm for adjustment of the best mounting distance of the bevel gear pair and develops a measuring and control software of the transmission error. The measuring principle of the single flank engagement of bevel gear pair based on the best mounting position was introduced and the evaluation method for the transmission error was described based on the transmission error analysis, frequency spectrum analysis and precision grade evaluations. Statistical Process Control (SPC) is used to evaluate and monitor the computation process of tangential composite error and the tooth to tooth tangential composite error. Then the measurement and control software was developed based on the best mounting position to implement data acquisition and processing, graphic display, the optimizing search of best mounting position and SPC statistical analysis. The class diagram, sequence diagram, test case diagram and the main interface of the software were designed. Finally, the transmission errors of a gear pair before and after optimizing search of best mounting position were measured and the different transmission errors of a gear pair at different mounting positions were given. Experiment results show that the method and software mentioned in this paper is suitable for the measurement of bevel gear pairs or face gear pairs.
