STUDY ON SURFACE WORKING QUALITY COEFFICIENT OF ROLLER CHAIN PLATE

Abstract

Abstract: Effect of surface working quality on fatigue strength of roller chain is studied, according to the routine processing method of roller chain plate hole. Through bunching fatigue test, R-S-N curves of different processing methods of plate hole and distribution of surface working quality coefficient under different expected life are obtained. Fatigue crack initiation and propagation of typical technologies are also analysed and studied from microscopic view. So it provided important basic data for fatigue reliability design.

Key words: Crack initiation, Crack propagation, Fatigue crack, Roller chain, Surface quality
