ABSTRACT:
A dynamic equivalent load P is calculated from data information of a rolling bearing. Next, a reliability coefficient a1is determined, a lubrication parameter aLcorresponding to a used lubricant is calculated, and a contamination degree coefficient acis determined in consideration of a material coefficient. A fatigue limit load Pu is calculated on the basis of the data information. Thereafter, a load parameter {(P−Pu)/C}·1/acis calculated. On the basis of the lubrication parameter aLand the load parameter {(P−Pu)/C}·1/ac, a life correction coefficient aNSKis calculated with reference to a life correction coefficient calculation map. The bearing life LAis calculated by LA=a1·aNSK·(C/P)p.
