Abstract
A bearing assembly for a gas turbine engine comprises a bearing; a bearing bracket, which holds the bearing and is secured by a predetermined breaking device on a connecting element, which can be connected or is connected to a loadbearing structure of the gas turbine engine; a first toothed component mounted on the bearing bracket; and a second toothed component fixed on the connecting element, wherein, after the destruction of the predetermined breaking device, the first toothed component and the second toothed component can be or are brought into engagement with one another in such a way that one of the toothed components can be made to roll on the other. A gas turbine engine and a method are furthermore provided.
Claims15
A bearing assembly for a gas turbine engine, comprising:
- a predetermined breaking device;
- a connecting element connected to a loadbearing structure of the gas turbine engine;
- a bearing;
- a bearing bracket, which holds the bearing and is secured by the predetermined breaking device on the connecting element;
- a first toothed component mounted on the bearing bracket;
- and
- a second toothed component fixed on the connecting element, wherein, after the destruction of the predetermined breaking device, the first toothed component and the second toothed component are brought into engagement with one another in such a way that one chosen from the first toothed component and the second toothed component rolls on the other of the first toothed component and the second toothed component.
A method for producing a bearing assembly for a gas turbine engine, comprising:
- providing:
- a predetermined breaking device;
- a connecting element connected to a loadbearing structure of the gas turbine engine;
- a bearing;
- a bearing bracket, which holds the bearing and is secured by the predetermined breaking device on the connecting element;
- a first toothed component;
- and
- a second toothed component;
- supporting the first toothed component on the bearing bracket such that, owing to destruction of the predetermined breaking device, the first toothed component and the second toothed component fixed on the connecting element are brought into engagement with one another such that one chosen from the first toothed component and the second toothed component rolls on the other of the first toothed component and the second toothed component.
