Load-hist Evaluation of Stresses and Deflection of Spur Gear Teeth Based on Exact Model

根据齿轮啮合原理 ,建立了轮齿的精确齿形。综合分析影响齿根应力的重要因素的基础上 ,创建了精确的二维和三维动态有限元模型 ,计算出齿根危险截面测点的应力历程和受载点的变形历程。最后 ,将计算结果与各类权威标准进行对照 ,证明了模型的正确性。

Based on gear engagement theory,the exact model of gear teeth is produced.Considering effects of major factors on root section stresses,2D and 3D dynamic finite element models are accurately established and then the history of both the stresses-loads at the test-points and the deflection-loads at the loading points are evaluated.The results from models developed by authors show reliable in comparison with those authoritative methods and ones.
