Deformation of the Ring Fitted in a Pipe with Grooves

Abstract

In fitting a shaft and rolling bearings or gears, the standards of fit quality are basically established by JIS according to its application or purpose. However it is difficult to select the most suitable fit quality because the work pieces are machined with some tolerances of profiles and dimensions, and these tolerances influence the contact pressure and deformation. A purpose of this study is the development of a pipe having grooves in its inside. In this study, stresses and displacements in a ring and pipe in fitting with interference are analyzed by means of finite element method with various types of groove and amounts of fitness.
