From cleanliness to rolling fatigue life of bearings -- A new approach

摘要: One of the main causes in-service spalling bearing steels is fatigue crack initiation from non-metallic inclusions. At present time, while relationship between endurance and cleanliness obvious, no quantitative them has been established. The aim this paper to a new method which predicts rolling life distribution bearings. This approach based on model in vicinity an inclusion steel matrix simple propagation relationship. basic used statistical describe scatter lives using inclusions Hertzian zone. fairly good agreement with results shows that constitutes real future tool for predicting influence material parameters
