Definitions
- the invention relates to an inclined shoulder bearing, in particular release bearing for clutches, with a bearing outer and a bearing inner ring, between which balls are preferably guided in a cage, the gap between the bearing outer and bearing inner ring being shielded at least on one bearing side.
- a release bearing for a clutch is also known, in which massive outer and inner bearing rings are provided, the outer ring extending approximately in the axial direction up to the center of the balls. Shielding of the large opening area between the bearing outer and inner bearing rings is achieved by an essentially L-shaped ring which adjoins a bead on the bearing outer ring with a step and on the opposite side of the bead for attachment to the bearing outer outer ring is flanged. The production and attachment of this ring is also expensive.
- the bearing outer ring has a substantially radially inwardly directed, integrally formed with the bearing outer ring, which extends beyond the gap between the bearing outer and inner bearing ring and forms the shield.
- This configuration ensures that no third component is required to shield the gap, but that a rim arranged on the outer bearing ring takes over this task.
- This rim can be molded onto the bearing outer ring in an advantageous manner if the bearing outer ring is thin-walled at least in this area and can be deformed due to the choice of its material.
- a preferred embodiment of the invention is achieved in that the rim is formed by flanging an axial edge strip of the outer bearing ring. This flanging of the edge area or of the circular strip is preferably carried out after installation of the balls and the bearing inner ring, so that the board prevents the shielding of the gap and, if it projects at least beyond the adjacent outer edge of the bearing inner ring, also prevents the bearing from falling apart during transport.
- the flanging is simplified and made more accurate if the edge area has a smaller wall thickness than the bearing outer ring or if a notch or groove is provided on the inner or outer surface of the bearing outer ring. As a result, lower forces are also required and the point at which the flanging takes place is precisely defined.
- the bearing inner ring has an essentially radially outwardly directed ring flange which projects with play up to the inner surface of the bearing outer ring. This ensures that the gap between the bearing outer and inner bearing ring is reduced to the game and that the radial dimension of the flanged rim can be kept small.
- the ring flange of the bearing inner ring can also be formed by flanging the edge region. This presupposes that the bearing inner ring is designed or selected in this area with respect to the wall thickness and the type of material so that it can be flanged.
- the ring flange can serve as a support for the bearing outer ring during the flanging.
- the play is preferably chosen to be very small, so that the bearing outer ring can be supported on the ring flange, in particular at the beginning of the flanging, the play being restored in the final phase of the flanging.
- FIG. 1 shows a cross section through an oblique shoulder bearing, in particular a release bearing for clutch clutches with the shielding according to the invention by means of a flange on the bearing outer ring.
- FIG. 1 designates an oblique shoulder bearing, which is designed in particular as a release bearing for clutches.
- the bearing has a bearing inner ring 2 which is formed from sheet steel in a manner known per se.
- the inner bearing ring 2 has a flange 3, on which, not shown, an actuating mechanism for the clutch engages.
- On the opposite side of the flange 3, the bearing inner ring has an annular flange 4 which extends with play up to the inner surface of a bearing outer ring 5.
- 6 balls 7 are arranged in a cage between the bearing inner ring and the bearing outer ring.
- the bearing outer ring 5 has, adjacent to the flange on the bearing inner ring 2, a pressure surface 8 which, also not shown, is at least temporarily operatively connected to a disengaging mechanism of a clutch.
- the bearing outer ring 5, which is also formed from sheet steel, has, adjacent to the ring flange on the bearing inner ring 2, a flange 9 which is formed by flanging from an edge strip of the bearing outer ring. The verge had already before
