Design improvement by Static Structural and Vibration examination of a bevel gear for epicyclic gear train in pugmill

The initial requirement for a project work is to identify and understand the nature of the problem. The problem is related to the automobile engineering and the Production area. The Bevel gear has crucial terminology. The tooth contact analysis (TCA) is an important resource for the design of gear drives. The contact pattern, contact path and the function of transmission errors that are directly related to the performance. The contact pattern are directly related to Spiral angle. This paper is related to spiral angle of the spiral bevel gear. Spiral angle is made by pitch cone radius and path of gear. We also improve the material of the spiral bevel gear. The material used for Bevel gear is usually Medium Iron Steel having Carbon 2.1- 4.5 wt.%, Si (normally 1-3 wt. %) Generate a three-dimensional solid CAD model, Solid Workbench 15.0 software is used as a design modeler. After the design modeling, the finite element model is generated using FEA software ANSYS. Then the engineering data tool is used to select various Gear materials that are 45C8, C55 and 40Cr4Mo3, then geometry is imported using ―IGS file conversion on ANSYS. After this the model is converted into meshed model. Then the boundary conditions are applied. The structural analysis model is used for the analysis of Gears. The output parameter is Total Deformation. The life of the Gear is calculated in the terms of Directional deformation. Total 15 numbers of cases are generated for analysis. For vibration analysis, analysis is done on 6 different frequency modes.
