摘要
在工程界现在普遍的趋势是要求重新研究各不同的标准以确是其在工业内最好的实践。本文介绍采用在ISO和AGMA标准对齿根强度估算方法的比较分析,并用开发的有限元和模型仿真进行证实。本分析(1)介绍了采用齿条和齿轮刀具制造的广大范围的直齿和斜齿轮,而(2)是齿轮主要几何学(齿轮设计),制造(齿条和齿轮刀具)和性能参数的不同组合,以及对每个齿轮进行齿根强度分析的有限元方法(FEM)。FEM的结果与用ISO和AGMA标准计算的相比较。对不同的设计、制造和性能参数组合的比较分析用图解说明和简要讨论。该结果将许可在现代工程实际中应用标准所存在的限制有一个很好的了解,并为改进和统一标准提供一个基础。
Current trends in engineering globalization require researchers to revisit various normalized standards that determine ＂best practices＂ in industries. This paper presents comparative analysis of toothroot strength evaluation methods used within ISO and AGMA standards and verifying them with developed models and simulations using the finite element method（FEM）. The presented analysis is conducted for （1） wide range of spur and helical gears manufactured using racks or gear tools; and for （2） various combinations of key geometrical （gear design）, manufacturing （racks and gear tools）, and performance （load location） parameters. FEM of tooth root strength is performed for each modeled geaer. FEM results are compared with stresses calculated based on the ISO and AGMA standards. The comparative analysis for various combinations of design, manufacturing, and performance parameters are illustrated graphically and dis cussed briefly. The results will allow for a better understanding of existing limitations in the current standards applied in engineering practice as well as provide a basis for future improve ments and/or unifications of gear standards.
