Abstract
A motion model of adjacent rollers and a contact model between rollers and raceways were established to improve the Archard wear model, and the automatic discrete failure conditions of bearing without cage were studied by combining finite element and experiment. The results show that adjacent rollers produce discrete spacing when passing through the reducer raceway, and the automatic discrete failure depends on the wear depth of the reducer raceway. The wear depth is related to the wear times. The wear depth increases linearly with the increase of wear times to a certain extent. The discrete spacing generated by the reducer raceway is not enough to disperse the adjacent rollers. The experimental results show that the wear depth of reducer raceway increases with the increase of bearing operation time, and the error decreases with the increase of wear time. The theoretical calculation value is slightly larger than the experimental value, and the average error is within an acceptable range, which verifies the correctness of the automatic discrete failure model and the automatic discrete numerical simulation.
