BEARING FOR ENERGY-DEPENDANT ACTIVE MAGNETIC SUSPENSION Russian patent published in 2005 - IPC

FIELD: mechanical engineering.

SUBSTANCE: bearing comprises stator of the radial support mounted in the housing and rotor provided with teeth on cylindrical surface and mounted on the shaft. The cylindrical surface faces the working surface of the stator of the radial support. The side poles of the stator are provided with teeth facing the rotor and shifted with respect to each other by half tooth pitch. The middle stator pole of the radial support is provided with excitation winding. The side poles are provided with winding of the generator connected in series. The free leads of the windings are connected with the voltage rectifier. The device has stator and rotor of the axial support arranged in the housing, ball bearing whose outer race is in a contact with the housing via flexible members mounted for permitting the shaft to move in axial and radial directions, and combined pickup for recording radial and axial positions of the support rotors. The stator of the pickup is connected with the housing through the control unit connected with the automatic control system. The rotor of the axial support, rotor of the combined pickup, inner race of the ball bearing are mounted on the shaft.

EFFECT: enhanced reliability and prolonged service life of bearing.
