Slip-free rolling bearing

摘要

A slip-free rolling bearing (1) is provided, in the outer ring (3) of which there is formed an encircling groove (7). The rolling bodies (2) of this rolling bearing are surrounded, in the manner of an envelope circle, by a central ring (8) and are in physical contact therewith. To ensure permanent drive of the rolling bodies, the central ring is inserted into the groove so as to be radially free but is fixed rotationally fixedly in said groove, wherein a radial depth of the groove is greater than a thickness of the central ring. The rotational fixing of the central ring in the groove of the outer ring is effected by a spring element.

1. A slip-free rolling bearing comprising an inner ring with a raceway,
an outer ring that surrounds the inner ring coaxially at a distance, the outer ring including a raceway rolling bodies that roll on the raceways provided by the inner ring and the outer ring, a completely closed middle ring that has an axial length that is reduced relative to an axial extent of the rolling bodies and contacts all of the rolling bodies as an envelope circle HK, the outer ring has a surrounding groove having an axial extent that is greater than the axial length of the middle ring and having a radial depth that is greater than a thickness of the middle ring in a radial direction, and the middle ring is arranged radially movable and rotationally locked in said groove.
