Abstract
A rolling-element bearing cage having a central axis of rotation includes a first cage ring having an axial extension and at least one snap arm disposed directly on the extension, and a second cage ring having an attachment region to which the at least one snap arm is snapped. The attachment region is located at a first distance from the central axis of rotation. A portion of each of the at least one each snap arm of the first cage ring is located at a second distance from the central axis of rotation, the second distance being less than the first distance.
Claims16
A rolling-element bearing cage having a central axis of rotation and comprising:
- a first cage ring having an axial extension and at least one snap arm disposed directly on the extension, and
- a second cage ring having an attachment region to which the at least one snap arm is snapped, the attachment region being located at a first distance from the central axis of rotation,
- wherein a portion of each of the at least one each snap arm of the first cage ring is located at a second distance from the central axis of rotation, the second distance being less than the first distance.
A method for assembling a rolling-element bearing cage, comprising:
- moving a first cage ring having an axial extension and at least one snap arm disposed directly on the extension axially toward a second cage ring having an attachment region such that each of the at least one snap arm is deflected radially inwards by a radially inner portion of the attachment region until the at least one snap arm is snapped to the attachment region.
A rolling-element bearing cage with a first cage ring which includes an axial extension and at least one snap arm disposed directly on the extension and at least one second cage ring which includes at least one attachment region at which the at least one snap arm for forming a snap connection is snapped, characterized in that there is
- wherein there is a section extending in the axial direction of the rolling-element bearing cage in which each snap arm of the first cage ring disposed directly on the extension has a smaller distance from a central axis of the rolling bearing cage extending in the axial direction of the rolling bearing cage than the attachment region.
