基于ISO 1328-1:2013的齿廓偏差评定方法研究

Evaluation method of gear profile deviations based on ISO 1328-1:2013

针对ISO 1328-1:2013中齿廓偏差定义及评定方法与前一版本差异较大的问题,对ISO 1328-1:2013中的齿廓偏差定义及评定方法进行了细化分析和计算,包括齿廓计值范围和齿廓计值长度、平均齿廓线拟合和齿廓测量数据滤波等方面。给出了符合ISO1328-1:2013的齿廓偏差评定流程,开发了基于ISO 1328-1:2013的齿廓偏差评定软件;采用齿轮测量中心获取齿廓测量数据,进行了齿廓偏差评定,对基于ISO 1328-1两个版本的齿廓偏差评定结果进行了对比分析,并在所开发的齿廓偏差评定软件中,计算和显示齿廓偏差评定参数、评定结果以及评定曲线。研究结果表明:对于同一组齿廓测量数据,基于两个版本标准的齿廓偏差评定结果存在一定的差异,该差异符合ISO 1328-1:2013相对于前一版本在齿廓偏差评定中做出的变更,可为ISO 1328-1:2013的应用提供参考。

Aiming at the large difference between ISO 1328-1:2013 and its previous version in 1995,the definition and evaluation methods of profile deviations in ISO 1328-1:2013 were studied.The detailed calculation results were analyzed including the profile evaluation range and profile evaluation length,the mean profile fitting,tooth profile measurement data filtering method.In accordance with ISO 1328-1:2013,the tooth profile deviation evaluation process was given and tooth profile deviation evaluation software was developed.With the meas-urement data of tooth profile obtained by the gear measuring center,the tooth profile deviation was evaluated and the results of tooth profile deviation based on two versions of ISO 1328-1 were compared and analyzed.The evaluation parameters,evaluation results and evaluation curves of tooth profile deviation were calculated and displayed in the developed software.The results indicate that there are certain differences between the evaluation results based on the two versions of the same group of tooth profile measuring data.The differences are in accordance with the changes made by ISO 1328-1:2013 in the evaluation of tooth profile deviation compared with the previous version,which can pro-vide reference for the application of ISO 1328-1:2013.
