摘要

本文介绍了一种用三维光弹性法计算非对称渐开线直齿轮根部弯曲应力的方法。非对称齿轮的齿廓在驱动侧和海岸侧有不同的压力角。采用ISO/TC-60方法对弯曲应力进行了理论计算。在CATIA V5 R15中生成齿轮的三维CAD模型，在ANSYS 14.5中进行有限元分析。采用三维光弹性法对齿轮齿根处的弯曲应力进行了实验计算。对对称和非对称直齿轮进行了有限元分析，估计了非对称直齿轮的抗弯强度变化。本文还对理论、实验和有限元法得到的应力值进行了比较。

3D photoelastic and finite element analysis of Asymmetric Involute Spur Gear

This paper explains a method to evaluate the bending stress at the root of Asymmetric Involute spur Gear using 3dimensional Photoelasticity method. Profiles of an asymmetric gear tooth on drive side and coast side have different pressure angles. The method ISO/TC-60 has been used to theoretically calculate the bending stresses. 3D CAD model of the said gear is generated in CATIA V5 R15 and the Finite Element Analysis is carried out in ANSYS 14.5. Three dimensional photoelasticity method has been used to evaluate the bending stresses, experimentally, at the tooth root of the gear. Finite Element analysis of Symmetric and Asymmetric Spur gear tooth has been carried out to estimate the change in bending strength owing to the asymmetry. The work also includes the comparison between the stress values obtained by theoretical, Experimental and FE method.
