Taschenbuch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Cageless ball bearings have the characteristics of a large number of rolling elements, high rigidity, and high load-bearing capacity. As a protective bearing for magnetic levitation bearings, when the magnetic levitation bearing fails, the rotor that falls due to the disappearance of magnetic force is supported to complete the rotational motion, protecting the magnetic levitation bearing stator and motor stator from damage. Scholars have found that the main reason for the failure of cageless bearings protection is due to the uncontrollable movement behavior of the isolated rolling element without cage, which leads to sliding phenomenon of the rolling element, friction and collision between the rolling element and the raceway or between the rolling element. In addition, compared to the consistency of the motion posture of the traditional bearing rolling element, the motion of rolling element about cageless bearing is stochastic. There is a lack of corresponding bearing theory research and non-contact method, which poses great challenges for controlling the motion of rolling elements about the cageless bearing.…
