Arrangement for holding a bearing system
An arrangement for force-free retention of a bearing system having an axis of rotation comprises a cylindrical hollow axle for concentrically receiving and holding the bearing system. By way of a hold-down and release mechanism, a bearing shell can be fastened to the hollow axle in such a manner that, when the bearing system is not acted upon by a load, all lateral and axial forces applied to the arrangement can be transmitted via the cylindrical hollow axle into axle receiving devices.
1. An apparatus for force-free holding of a bearing system having an axis of rotation, said apparatus comprising:
a cylindrical hollow axle for concentrically receiving and holding of the bearing system;
a bearing shell; and
a hold-down and release mechanism for fastening the bearing shell to the hollow axle such that, when the bearing system is not acted upon by a load, all lateral and axial forces applied to the apparatus are transmitted via the cylindrical hollow axle into axle receiving devices.
2. The apparatus according to claim 1 , wherein the bearing shell surrounds the hollow axle in the circumferential direction.
3. The apparatus according to claim 1 , wherein the hollow axle comprises two mutually symmetrically arranged partial axles which are connected with one another by way of the bearing system.
4. The apparatus according to claim 3 , wherein at their mutually facing ends, the partial axles each have a flange with a bore for receiving and holding the bearing system.
5. The apparatus according to claim 4 , wherein the bearing system is connected with the flanges of the partial axles.
6. The apparatus according to claim 3 , wherein at their mutually facing ends, the partial axles each have a groove on their exterior side, the bearing shell form-lockingly engaging in the groove.
7. The apparatus according to claim 6 , wherein the respective grooves have continuous constructions.
8. The apparatus according to claim 6 , wherein the bearing shell comprises first and second bearing shell parts, which, at a first end, are rotatably connected with one another and which, at a second end, opposite said first end, are connected with one another by means of the hold-down and release mechanism.
9. The apparatus according to claim 8 , wherein:
a spring element is provided between the two ends of the bearing shell parts; and
the spring element causes a defined opening of the bearing shell parts when the hold-down and release mechanism is triggered.
10. The apparatus according to claim 1 , wherein the bearing system is connected with the hollow axle in a material-locking manner.
11. The apparatus according to claim 1 , wherein the hold-down and release mechanism comprises a bolt separating mechanism.
12. The apparatus according to claim 1 , wherein the hollow axle is constructed of a highly rigid material.
13. The apparatus according to claim 1 , wherein the bearing shell is constructed of a high-strength material.
14. The apparatus according to claim 1 , wherein the hollow axle is manufactured in a single setting.
15. The apparatus according to claim 1 , wherein the bearing system is a tension-free Flexpivot bearing.
