Abstract

Installation errors and cracks in the herringbone gear transmission system (HGTS) can alter its dynamic response, decreasing transmission performance and compromising operational safety. Traditional methods to determine the time-varying meshing stiffness (TVMS) of herringbone gears often neglect the impact of the groove, treating the herringbone gear as two helical gears in dynamic models. To address these deficiencies, a new stiffness calculation formula for the herringbone gear pair is proposed, incorporating the combined effects of installation errors and cracks. The TVMS distribution of multiple springs in the dynamic model is determined based on the load distribution during meshing. On this basis, a dynamic model of the cracked HGTS considering installation errors is constructed. The effects of crack faults and installation errors on the dynamic response of the HGTS are investigated. It is found that installation errors aggravate the effect of crack faults on the dynamics of the HGTS.

考虑安装误差的裂纹人字齿轮传动系统动力学建模与响应分析

人字齿轮传动系统（HGTS）的安装错误和裂纹会改变其动态响应，降低传动性能并影响操作安全性。传统的确定人字齿轮时变啮合刚度（TVMS）的方法往往忽略了槽的影响，在动力学模型中将人字齿轮视为两个斜齿轮。针对这些不足，提出了一种考虑安装误差和裂纹综合影响的人字齿轮副刚度计算公式。根据啮合时的载荷分布确定了动态模型中多个弹簧的TVMS分布。在此基础上，建立了考虑安装误差的HGTS开裂动力学模型。研究了裂纹故障和安装误差对高架梁动力响应的影响。研究发现，安装误差加剧了裂纹故障对高架梁动力学的影响。
