回转耕耘机变速箱直齿圆锥齿轮的有限元分析

Finite Element Analysis of Stright Bevel Gear of Rotative Cultivator

在Pro/E2.0中建立立式回转耕耘机变速箱圆锥齿轮的三维几何模型,通过无缝连接接口把Pro/E2.0中圆锥齿轮的三维几何模型导入ANASYS10.0中。对圆锥齿轮进行了有限元分析,得出了应力-应变云图。有限元法分析的结果验证了用SOLID92法划分网格可以更加清晰、准确地显示齿轮的形变,显示了圆锥齿轮的关键变形为径向变形。研究结果为回转耕耘机变速箱研究设计提供了理论依据。

This article firstly create three-dimensional geometric model of stright bevel gear of totative cultivator by Pro/E2.0,and then seamlessly import the three-dimensional geometric model of bevel gear into the ANSYS10.0.Through the finite element analysis of stright bevel gear,we get the stress-strain nephogram.The results of finite element analysis of this paper show us that we can get more clear and accurate deformation of the gear by using SOLID92 grid,and also show us that the the critical deformation is radial deformation.The result of the research provides the study of stright bevel gear of totative cultivator with a theoretical basis.
