| description | For inner ring or outer ring rotation of high-speed rotor ball bearings, a dynamic wear simulation model of angular contact ball bearings was built up. Taking one type of instrument rotor bearing as an example, the influence of different ring rotation and rotating radial load on the dynamic performance and wear rate of bearing parts were analyzed. Results show that under the same ring speed condition, the angular and orbital velocity of the balls are higher when the outer ring rotates; the difference of the contact angles between the ball and the inner and outer races is also increased which result in an increase in the spin-to-roll ratio, and the time-averaged wear rate of the ball is increased by 31.30%. Compared with the pure thrust load condition, the track radius and the axial swing amplitude of the cage mass center whirl are increased under the combined thrust and rotating radial load. When the ratio of the radial to thrust load is 1, the wear rates of bearing parts are obviously increased. The results provide some guidance for the optimization design and application of high-speed instrument rotor bearings. |
