Abstract

Meshing impact is one of the three major internal excitations that cause vibration and noise in gear systems. Ingress impact is the most significant component of meshing impact. Current research typically considers the ingress impact within a meshing period while neglecting the different impacts of the integrated systematic errors of each gear pair on it. However, in practical scenarios, it is unrealistic to presume that the systematic errors of each tooth are identical. Base pitch errors, for instance, are crucial metrics that reflect the quality of gear manufacturing, and empirical measurements have confirmed that these errors are indeed non-uniform. Therefore, the current calculation methods for ingress impact limit the accurate representation of the dynamic behavior of gear systems. Based on this, a model that captures the ingress impact throughout the full-tooth meshing period is established. When compared with the traditional calculation method, which solely considers the ingress impact in a single meshing period, the results demonstrate that the method proposed in this paper offers a superior description of the dynamic behavior of gear systems.

考虑全齿啮合周期的侵入冲击对斜齿轮系统动态特性的影响
啮合冲击是导致齿轮系统振动和噪音的三大内部激励之一。输入冲击是啮合冲击中最重要的组成部分。目前的研究通常考虑的是啮合周期内的输入冲击,而忽略了每对齿轮的综合系统误差对其产生的不同影响。然而,在实际应用中,假设每个齿的系统误差都是相同的是不现实的。例如,基距误差是反映齿轮制造质量的关键指标,而经验测量证实这些误差确实是不均匀的。因此,目前的入齿冲击计算方法限制了对齿轮系统动态行为的准确表述。在此基础上,我们建立了一个能捕捉整个全齿啮合期间的入齿冲击的模型。传统的计算方法只考虑单个啮合周期的入齿冲击,与之相比,结果表明本文提出的方法能更好地描述齿轮系统的动态行为。
