Roller bearing cage with predetermined rupture point
View Patent ↗A roller bearing cage 16 with roller bearing pockets 18 which are arranged one next to the other in the circumferential direction and have the purpose of holding load-bearing roller bodies 10 of a roller bearing, wherein at least one end piece 14 which engages behind a roller bearing component 12 is formed on the roller bearing cage 16 . The end piece 14 , which is ideally embodied as a retaining claw, holds the inner ring and the roller body 10 together, but can be removed after or during the assembly by means of a predetermined rupture point 15 , in order to make room for a further component, such as for example a sealing arrangement. As a result, despite the installation assistance, optimum use of the installation space is provided.
1. A roller bearing cage comprising:
a cage defining roller body pockets arranged side by side in the circumferential direction for receiving load-bearing roller bodies of a roller bearing; and
at least one end piece connected to the cage and engaging behind a roller bearing component, the end piece having a structurally or materially weakened connecting piece toward the roller body pockets, the connecting piece designed to rupture at a certain bending load in order to separate end piece permanently from the cage.
2. The roller bearing cage as recited in claim 1 wherein the connecting piece is weakened structurally by a notch, an incision or a recess.
3. The roller bearing cage as recited in claim 1 wherein the connecting piece is weakened materially by an addition or a mixture of a substance.
4. The roller bearing cage as recited in claim 1 wherein the end piece includes a retaining claw.
5. The roller bearing cage as recited in claim 1 wherein the end piece includes an actuating element on an end remote from the roller body pockets.
6. The roller bearing cage as recited in claim 5 wherein the actuating element is continued at least in part in the circumferential direction.
7. The roller bearing cage as recited in claim 1 further comprising a further permanently separable, engaging-behind end piece.
8. The roller bearing cage as recited in claim 1 wherein the roller bearing component is an inner ring, an outer ring, a rib washer or a component part of a sealing arrangement of the roller bearing.
9. The roller bearing cage as recited in claim 1 wherein a bending load necessary for permanent separation is dimensioned in such a manner that a rupture of the connecting piece can be carried out manually.
10. The roller bearing cage as recited in claim 1 wherein the structurally or materially weakened connecting piece is weakened in the circumferential direction or in the radial direction.
11. A roller bearing comprising the roller bearing cage as recited in claim 1 .
12. A wheel bearing comprising the roller bearing cage as recited in claim 1 .
