“…For high-speed rolling bearings, the cage–ball friction phenomenon can considerably influence the bearing stability. Houpert et al [ 52 ] found that cage–ball friction can cause bearings to produce an additional braking effect. Dumitru et al [ 53 ] noted that the cage–ball friction is a crucial friction source in extremely low axial force conditions.…”

Because of the operating environment and load, the main fault form of flywheel bearing is the friction fault between the cage and the rolling elements, which often lead to an increase in the friction torque of the bearing and even to the failure of the flywheel. However, due to the complex mechanism of the friction fault, the characteristic frequencies often used to indicate cage failure are not obvious, which makes it difficult to monitor and quantitatively judge such faults. Therefore, this paper studies the mechanism of the friction fault of the flywheel bearing cage and establishes its fault feature identification method. Firstly, the basic dynamic model of the bearing is established in this paper, and the friction between the cage and the rolling elements is simulated by the variable stiffness. The influence law of the bearing vibration response reveals the relationship between the periodic fluctuation of cage-rolling element friction failure and the bearing load. After analyzing the envelope spectrum of the vibration data, it was found that when a friction fault occurred between the cage and the rolling element, the rotation frequency component of the cage modulated the rotational frequency component of the rolling element, that is, the side frequency components appeared on both sides of the characteristic frequency of the rolling element (with the characteristic frequency of the cage as the interval). In addition, the modulation frequency components of the cage and rolling element changed with the severity of the fault. Then, a modulation sideband ratio method based on envelope spectrum was proposed to qualitatively diagnose the severity of the cage-rolling element friction faults. Finally, the effectiveness of the presented method was verified by experiments.

“…The conclusion showed that the self-excited vibration will aggravate the vibration of the shaft system and the entire unit. Huang et al [6] took the shaft-bearing system as the research object, studied its interaction behavior in detail, and proposed a vibration numerical model considering stick-slip friction. Peng et al [7] studied the vibration of the ship's water-lubricated stern bearing shaft and bearing seat.…”

In order to study the influence of water-lubricated bearings on the vibration of the marine magnetic pump, the vibration characteristics of the marine magnetic pump under different flow rates and bearing structural parameters (bearing clearance, eccentricity, and length–diameter ratio) were numerically analyzed. The internal flow fields of marine magnetic pumps and water-lubricated bearing were numerically calculated, and experimental verification of their external characteristics results was conducted. The results show that the vibration velocity level of the pump increases with the increase in the bearing clearance and the bearing eccentricity, and the vibration velocity level of the pump gradually decreases with the increase in the bearing length–diameter ratio. The clearance has the greatest influence on the vibration of the pump, the length–diameter ratio the second, and the eccentricity the smallest. The peak value of vibration velocity at the pump outlet at the vibration measurement point is the highest, the peak value of vibration velocity at the pump inlet is second, and the peak value of vibration velocity at the pump foot is the smallest. However, the peak value of vibration velocity at the pump inlet is most sensitive to changes in operating conditions and bearing structural parameters, with a maximum increase of 6.2 dB. Therefore, the change in the peak value of vibration velocity at the pump inlet can be used as the main indicator for monitoring the operating status of bearings.
