Heating bronze cog for interference fit
Webroughness in interference fit and demonstrate experimentally that the extraction load varies by up to 300% for Ra values of 0.24-6.82 m. Zhang et al. (2000) analysed an interference fit of a ring gear and a stepped shaft using both numerical and analytical methods and conclude that the Lame’s equations underestimate the contact pressure WebShrink-fits are assembled by heating them to temperatures where the expansion exceeds the interference. Required heating temperature can be calculated as. dt = δ / α di (1) …
