Abstract:
A wobble-absorbing magnetic bearing for a drive system that applies force from a driving mover to move a driven object; said bearing comprising:a driving bearing element having a first surface;a driven bearing element having a second surface that faces the first surface along a drive direction;rolling elements disposed between the first and second surfaces to:enable the driving and driven bearing elements to move substantially freely, relative to each other, along at least one direction transverse to the drive direction, andtransmit drive forces along the drive direction from the driving bearing element to the driven bearing element;means for receiving driving contact from such driving mover at the driving bearing element;means for applying driving contact from the driven bearing element to such driven object; andmeans for applying magnetic force to hold the bearing elements together against the rolling elements.
