Abstract

A cage of a roller bearing includes at least two cage segments, wherein each cage segment is formed from two side pieces, which are disposed at an axial distance from one another, and from a plurality of webs that are circumferentially distanced from each other and that connect the side pieces in the axial direction, wherein each cage segment forms an arc of a given arc length, the plurality of webs includes a center web, which maintains a distance of half the given arc length from the circumferential ends of the respective cage segment, and wherein the center web is penetrated by a bore the center axis of which approximately runs through the center of gravity of the cage segment, and which is configured to accommodate a radially outwardly directed moving device in a releasable manner.

First claim

The invention claimed is:

1. A cage of a roller bearing, comprising:
at least two cage segments, wherein each cage segment is formed from two side pieces, which are disposed at an axial distance from one another, and from a plurality of webs that are circumferentially distanced from each other and that connect the side pieces in the axial direction, wherein each cage segment forms an arc of a given arc length, the plurality of webs includes a center web, which maintains a distance of half the given arc length from circumferential ends of the respective cage segment, and wherein the center web is penetrated by a bore the center axis of which approximately runs through the center of gravity of the cage segment, and which is configured to accommodate a radially outwardly directed moving device in a releasable manner.

2. The cage of claim 1 , wherein the moving device includes an eye.

3. The cage of claim 1 , wherein the moving device includes a rod.

4. The cage of claim 3 , wherein the rod comprises an eye.

5. The cage of claim 1 , wherein each cage segment has two end webs that complete the cage segment in the circumferential direction, and wherein at least one of the center web and two end webs of each cage segment has a greater extent, at least in the circumferential direction, than the other webs in the plurality of webs of each cage segment.

6. The cage of claim 5 , wherein the cage segments of the cage are connected to one another at the end webs of the respective cage segments.

7. The cage of claim 1 , wherein at least one of the side pieces has a radially inwardly directed lowering of an outer peripheral edge thereof relative to the center web.

8. The cage of claim 1 , wherein said cage is configured for receiving at least one of a plurality of spherical rollers and a plurality of cylindrical rollers.

9. A mounting method for a split cage of a split rolling bearing that includes an inner bearing ring and an outer bearing ring, wherein the split cage includes a plurality of cage segments, wherein each of the plurality of cage segments is formed from two side pieces, which are disposed at an axial distance from one another, and from a plurality of webs that are circumferentially distanced from each other and that connect the side pieces in the axial direction, wherein each cage segment forms an arc of a given arc length, the plurality of webs includes a center web, which maintains a distance of half the given arc length from circumferential ends of the respective cage segment, and wherein the center web is penetrated by a bore the center axis of which approximately runs through the center of gravity of the cage segment, and which is configured to accommodate a radially outwardly directed moving device in a releasable manner, comprising the steps of:
raising at least one of the plurality of cage segments via at least one raising device acting on the moving device of the at least one cage segment;
placing the at least one cage segment on the inner bearing ring; and
applying a force on the moving device of the at least one cage segment in the circumferential direction to move the at least one cage segment radially between the outer bearing ring and the inner bearing ring.

10. A cage segment of a cage of a roller bearing, comprising:
a first side piece;
a second side piece in an axially-spaced relationship with the first side piece; and
a plurality of webs that are circumferentially distanced from each other and that connect the first and second side pieces in the axial direction, the plurality of webs including a central web which is penetrated by a bore that is configured to releasably accommodate a radially outwardly directed moving device, and the plurality of webs further including first and second end webs disposed at opposite circumferential ends of the cage segment, wherein the first and second end webs extend circumferentially to a greater extent than at least one of the plurality of webs.

11. The cage segment of claim 10 , wherein the central web extends circumferentially to a greater extent than at least one of the plurality of webs.

12. The cage segment of claim 10 , wherein a center axis of the bore that penetrates the central web approximately runs through the center of gravity of the cage segment.
