There are many ways to fail the rolling bearing; however, there are no available life-calculation methods until the failure mode; as long as the fatigue life, wear life, smooth life and fretting life can be quantitatively evaluated by accounting .
(1) The fatigue life is smooth and the other conditions are normal; the rolling bearing often fails due to fatigue; its hope that the fatigue life can be obtained from the sample; the formula and the accounting procedure are surely reliable. Sexual calculations come out.
(2) Wear life The machine tool spindle usually takes large diameter to ensure its high rigidity; the size of the bearing is correspondingly large; before it reaches the exhaustion limit; often loses the necessary precision due to wear and tear, so it cannot be used continuously; It is necessary to use the wear life to measure the service life of the bearing. In fact, most of the bearings used in the field fail due to excessive wear; so it is also necessary to consider the problem of wear life.
(3) The smooth life expectancy is mainly about double-sided sealed grease-smooth bearings; one-time grease filling will not make up for fatliquoring in the future; the life of the bearing at this moment depends on the service life of smooth grease.
(4) Frequently abraded life winches, cantilever cranes and gearboxes, and bearings in organizations such as automobile clutches; infrequent wear damage caused by oscillating loads in their non-operating state; The leading cause; the bearing in such an organization; sometimes the need to account for its fretting abrasion life.
