Abstract
A safety device (10) for a bearing arrangement of a rotor of a turbomachine, whereby the safety device (10) includes at least two support structures (12) between which at least one buckling structure (14) is arranged that is configured to collapse when a predetermined buckling load that acts on at least one of the support structures (12) is exceeded, thereby reducing the volume of the safety device (10). A method for the production of a safety device (10) for a bearing arrangement of a rotor of a turbomachine, as well as to a bearing arrangement of a rotor of a turbomachine having such a safety device (10).
Claims23
A safety device for a bearing arrangement of a rotor of a turbomachine, the safety device comprising:
- at least two support structures;
- and
- at least one buckling structure between the at least two support structures;
- at least one void adjacent to the at the least one buckling structure;
- wherein the at least one buckling structure is configured to collapse into the at least one void when a predetermined buckling load acting on at least one of the support structures is exceeded, the collapse reducing a volume of the safety device.
A method for making a safety device for a bearing arrangement of a rotor of a turbomachine, the safety device comprising at least one buckling structure arranged between at least two support structures, the method comprising forming the buckling structure in such a way that the buckling structure collapses into at least one adjacent void when a predetermined buckling load that acts on at least one of the support structures is exceeded, thereby reducing the volume of the safety device.
