Effects of size and raceway hardness on the fatigue life of large rolling bearing

다국어 초록 (Multilingual Abstract)

Although there are a large number of studies on large rolling bearings, analyses are seldom for the effects of size and raceway hardnesson their fatigue life. In this study, taking the four contact-point ball bearings as an example, the fatigue lives of large rolling bearings withdifferent structure sizes were calculated through the stress life (σ-N), strain life (ε-N) and international standard (ISO) methods, respectively.

The maximum contact force and subsurface stress in the raceway were obtained with the finite element method. At the same time,the effect of raceway hardening depth on bearing life was taken into account. Results showed that the effect of raceway hardening depthon the life of large rolling bearing was obvious. Thus, the raceway hardening depth cannot be ignored when calculating the fatigue life oflarge rolling bearing. When used with the load at the same level, the rolling bearing with larger size usually had less the fatigue life.
