Abstract:
In this paper, according to the theory of mechanical reliability,
the fatigue life model for multi-row rolling bearings that bases upon
contact fatigue strength and considers the effect of blased load on the
life of rolling bearings is established. 3-722 four-row tapered roller
bearing is taken as an example. Through contact fatigue test and field
reliability test for it, the accuracy of the model is examined. Result
shows that life value calculated by the model is better coincident with
actual used life.
