摘要： A structure and method of operation of a journal bearing is disclosed that minimizes contact of the shaft with the sleeve during start up and slow down of rotation of the shaft relative to the sleeve, or vice versa. The bearing assembly includes a gravitational load reduction mechanism with magnets disposed on the sleeve and on the shaft in alignment with one another. The magnet(s) on the shaft interacts with the magnet(s) disposed on the sleeve to provide a force against the pressure of the shaft towards the sleeve generated by gravity on the rotating component. The magnets enable centering of the rotating component within the stationary component during low rotation and non-rotation. This prevents rubbing of the rotating journal bearing component surfaces, e.g., sleeve, against the stationary journal bearing component, e.g., shaft, during assembly, ramp-up, and coast-down when the journal bearing fluid provides minimal or no bearing centering capability.

摘要： An energy storage system comprises a housing and a flywheel having a drive shaft portion attached to a cylindrical ferromagnetic rotor portion. The drive shaft portion defines a substantially vertical axis about which the rotor portion is mounted for rotation. A magnetic bearing assembly comprised of an annular permanent magnet having no electromagnetic components is mounted on the housing in stationary centered relation about the vertical axis above the rotor portion so as to attract the rotor portion axially upwardly towards a lower face of permanent magnet, thereby supporting a significantly high portion of the weight of the flywheel. At least one low friction mechanical bearing assembly is mounted within the housing about the drive shaft portion to provide radial positioning of the rotor portion and to limit at least upward axial movement of the rotor portion in relation to the lower face. The annular permanent magnet overlies a portion of the end face of the rotor with the balance providing a return path for magnetic flux.
