S1105-2-2 A Study of Wear Reduction of Pin/Bush in Roller Chain

Abstract

There was strong wear around the both ends of a pin up to now about wear of a pin of Laura Chen/Busch, and I made it clear that a pin central part doesn't touch Busch. I can think it's effective to expand the contact range into the whole pin and make them reduce the contact pressure to make them reduce wear of a pin/Busch. So it was confirmed by this research that contact territory feels the pin shape is wide theoretically by applying the crowning shape which could inflate a central part, not straight. I made it clear to be able to reduce more wear by an experiment.
