Abstract:
Fatigue
crack initiation and propagation in AISn20Cu bearing are observed by
fatigue test. Journal center orbit, oil film pressure and stress
distribution on alloy got from calculating are taken as the basis for
analyzing the bearing fatigue process and result accords with the test
result, which provides a new way for studying fatigue crack in bearing.
Key words:
Bearing
Oil film pressure Stress Crack
