Bearing Raceway Flaking Propagation Analysis Method, Flaking Analysis Device, And Program

Abstract: This flaking development analysis method involves: acquiring the presence or absence of flaking of a raceway ring and the shape of a flaked portion; calculating a rolling element load acting on a rolling element, in consideration of progression in the shape of the flaked portion, when the rolling element passes an exit portion of the flaked portion of the raceway ring, on the basis, at least, of the acquired shape of the flaked portion, the specifications of a rolling bearing, and the operating conditions of the rolling bearing; calculating a speed of development of flaking in consideration of progression in the shape of the flaked portion, on the basis of the rolling element load at the exit portion of the flaked portion; and calculating a relationship between elapsed time and the shape of the flaked portion on the basis of the speed of development of flaking.
