Abstract
This paper deals with the analysis of the contact forces developed by a helical spring shrink fitted on acircular shaft. This interference fit is an effective, fast to apply, reversible and inexpensive fastener. An analyticalsolution able to predict the contact forces distribution and the maximum thrust which the system can withstand hasbeen developed. The analytical results have been compared with a finite element analysis confirming theeffectiveness of the developed formulas.
