Design and Implementation of Tractor Front Wheel Hub by the Help of Finite Element Analysis

Abstract

In this thesis to study the work undertaken developing technique for the design of tractor front wheel hub for increased reliability of hub in whole working condition &weight reduction of wheel hub with the help of finite element analysis. Also increase the life of taper roller roller bearing & oil seal which are generally used in front tractor wheel hub. For this protection& smooth running, we design a cover to prevent the oil seal from mud& foreign material. Design a channel, for proper lubrication separation in hub & lubrication breathing system in running conditions. The weight and dimension of the hub must be small as possible because of the unsprungweight which further reduce the rotational mass. We use for better result which used in physical scenario. The objective was to reduce the mass of the wheel center and that has been achieved. With respect to the finite element formulation, the next important parameters are the mesh density and normal contact stiffness factor if augmented Lagrange is used. The mesh density affects the contact stiffness and the whole reaction force mostly in center where taper bearing in attach.The second goal of this study is to find out all the problem and changes to make a successful working of the wheel hub and reduce the weight of hub.
