The analysis of the static behavior of special roller bearings with forged outer ring

Abstract

This paper presents an analysis of stiffness and stress on the Hub unit bearing (HUB). The mathematical model consists of two parts. The first part of the developed software solution to determine the contact stiffness for each rolling elements, while the second part on the basis of contact stiffness determines the stiffness and stress of bearing based on the finite element method. Software solution is developed based on Hertz's contact load and John Harris of the quasi-static equilibrium equations. Mathematical model analyzes the influence of the cornering acceleration of the automotive wheel on the bearnig stiffness and stress. The research in this paper shows that the cornering acceleration of the automotive wheel significantly affects the axial, radial and angular stiffness from one side. On the other hand, lateral acceleration wheel significantly affectes the increase in stress on the flanged outer ring which are made by forging.
