齿轮作为传动装置中的核心部件，传动时齿面上的接触应力大小对机械产品的性能和寿命具有重要影响。本文以传动装置中的一对斜齿轮副为研究对象，采用KISSsoft软件进行齿轮接触应力的仿真分析，并通过Visual Basic语言调用KISSsoft软件建立齿轮的参数化模型，实现齿轮接触应力分析的参数化和自动化。在此基础上借助ISIGHT优化设计平台实现齿轮接触强度的可靠性分析和参数灵敏度分析。分析结果表明，本文所提方法具有非常好的工程适用性，能够充分考虑输入变量的随机不确定性，准确分析出在输入参数分散性存在下齿轮接触应力强度可靠性结果，并能给出各随机参数对接触应力的影响规律。本文的分析方法具有广泛适用性，可为其他类型的齿轮接触强度可靠性分析提供技术参考。
As the core component of the transmission device, the contact stress on the tooth surface has an important impact on the performance and service life of mechanical products. Taking a pair of helical gear pairs in the transmission device as the research object, this paper uses KISSsoft software to simulate and analyze the gear contact stress, and calls KISSsoft software to establish the parametric simulation model of the gear through Visual Basic language, so as to realize the parameterization and automation of the gear contact stress analysis. On this basis, the reliability analysis and parameter sensitivity analysis of gear contact strength are realized with ISIGHT optimization design platform. The analysis results show that the method proposed in this paper has very good engineering applicability, can fully consider the random uncertainty of input variables, accurately analyze the reliability results of gear contact stress strength in the presence of dispersion of input parameters, and can give the influence law of random parameters on contact stress. The analysis method in this paper has wide applicability and can provide technical reference for other types of gear contact strength reliability analysis.
