  • Method for fatigue assessment of rolling bearing
    Patent number: 9074970
    Abstract: The present invention related to a method, and an apparatus arrangement, for determining a fatigue limit for rolling contact initiated fatigue of a rolling bearing. The method comprises running a rolling bearing while being exerted to a load which generates sub-surface transformations in a rolling element contact zone of the outer or inner ring. Furthermore a set of sub-surface transformations in the contact zone along a raceway portion of the rolling bearing is identified and measured and used for generation of a parameter data set, wherein a fatigue parameter value representative of a predicted fatigue limit for the rolling bearing is determined based on the generated data set of sub-surface transformations.
