本文论述齿轮副侧隙的测量过程及数据处理方法。通过实测情况的分析,认为用峰值法来予测一批齿轮副可能侧隙的范围在工程中更为可靠。 This article discusses the gear backlash measurement process and data processing methods. Through the analysis of the actual situation, it is considered that the range of possible backlash of a group of gear pairs measured by the peak method is more reliable in the project.
