摘要

目前，研究磨损对齿轮动力学特性的影响大多采用传统的Archard磨损模型，并未考虑齿轮的润滑特性，且主要研究对象多为直齿轮。为了弥补斜齿轮研究方面的不足，数值模拟了混合弹流润滑状态下斜齿轮的磨损过程，建立了一个8自由度斜齿轮动力学模型，研究齿面磨损对斜齿轮动态特性的影响。在斜齿轮试验台上进行了齿轮疲劳试验，对数值仿真结果进行验证。结果表明，齿面磨损主要发生在靠近齿根和齿顶部分，且由于齿根处较高的滑滚比导致其磨损更加严重。根据齿轮啮合频率及其谐波幅值的变化可知，磨损导致齿轮的振动增加。试验分析与数值仿真有较好的一致性，说明该研究可以为斜齿轮磨损的预测和故障诊断提供可靠的理论依据。

Abstract

At present， the traditional Archard wear model is mostly used to study the influence of wear on the dynamic characteristics of gears， without considering the lubrication characteristics of gears, and the main research objects are mostly straight gears. In order to make up for the shortage of research on helical gear， the wear process under mixed elastohydrodynamic lubrication is numerically simulated. An eight-degree of freedom dynamics model of helical gear is established to investigate the influence of tooth surface wear on gear dynamic characteristic. The gear fatigue test is carried out on a helical gearbox test rig to validate the numerical results. The results show that the wear mainly occurs on the region close to the tooth root and tooth tip， and the maximum wear occurs at the tooth root due to the relative high sliding-to-roll ratio. The variation of the amplitudes of the gear meshing frequency and its harmonics demonstrates that the wear causes an increase in gear vibrations. The experimental results show a good agreement with the numerical results， which implies the study can provide a reliable theoretical basis for the prediction and fault diagnosis of helical gear wear.
