    • A magnetic bearing assembly, either radial or linear, utilizes attractive magnetic forces between inner and outer components of the assembly. The assembly includes a mechanical device for controlling relative movement between the components in first and second directions, while permitting relative movement between them in a third direction. At least one of the components, separated by a gap, has a magnetic source for creating a magnetic field extending across the gap and causing a first load in a direction opposing gravity exerted across the gap and against that component adapted to receive a supplemental load. In this way, the attractive force urges the component adapted to receive the supplemental load upward against the mechanical device, thereby at least partially offsetting the load on the mechanical device caused by the weight of the supplemental load. Either component may be the moving component or the one adapted to receive the supplemental load.
    • 径向或线性的磁轴承组件在组件的内部和外部部件之间利用有吸引力的磁力。 组件包括用于控制第一和第二方向上的部件之间的相对运动的机械装置,同时允许它们在第三方向上的相对运动。 由间隙分开的至少一个部件具有用于产生延伸穿过该间隙的磁场的磁源,并且使得在与该间隙相对的重力方向上相反的方向上的第一负载和适于接收补充负载的该部件。 以这种方式,吸引力促使组件适于向机械装置向上接收补充负载,从而至少部分地抵消由补充负载的重量引起的机械装置上的负载。 任何一个组件可以是移动组件或适于接收补充负载的组件。

    • A magnetic bearing assembly utilizes repulsive magnetic forces between components, having magnetic sources, of the bearing at two or more gaps which are angled with respect to an axis of the inner component. Each gap provides force vectors in two directions, while allowing for relative movement of the components in a third direction. The gaps collectively provide a stable equilibrium in the first two directions, meaning that, in response to relative movement of the components in the first or second direction causing a decreased gap width, magnetic repulsive forces at the decreased gap width urge the components away from each other to return to equilibrium. The components of a radial magnetic bearing according to the invention move relative to one another rotationally, and the components of a linear magnetic bearing according to the invention move relative to one another longitudinally.
    • 磁轴承组件在相对于内部部件的轴线成角度的两个或更多个间隙处利用轴承的具有磁源的部件之间的排斥磁力。 每个间隙在两个方向上提供力向量,同时允许部件在第三方向上的相对运动。 这些间隙在前两个方向上共同提供稳定的平衡,这意味着响应于第一或第二方向上的部件的相对移动导致间隙宽度减小,在间隙宽度减小的磁性排斥力促使组件远离每个 其他回到平衡。 根据本发明的径向磁轴承的部件相对于彼此旋转运动,并且根据本发明的线性磁轴承的部件相对于彼此纵向移动。
