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 support structure of the gas turbine engine; and a clutch for transmitting a torque from a first clutch element connected in a fixed manner to the rotor of the bearing to a second clutch element supported on the bearing bracket, wherein the clutch elements are spaced apart when the predetermined breaking device is intact and can be brought into contact with one another by destruction of the predetermined breaking device. A gas turbine engine and a method are furthermore provided.
Claims16
A bearing assembly for a gas turbine engine, comprising:
- a bearing having a stator and a rotor rotatable relative thereto;
- a bearing bracket, which holds the bearing;
- a connecting element including an annular, projecting extension configured to be connected to a support structure of the gas turbine engine,
- a predetermined breaking device including at least one shear pin and being secured on the connecting element;
- and
- a clutch for transmitting a torque from a first clutch element connected in a fixed manner to the rotor of the bearing to a second clutch element supported on the bearing bracket, wherein the first and second clutch elements are spaced apart when the predetermined breaking device is intact and are brought into contact with one another by destruction of the predetermined breaking device via shearing of the at least one shear pin.
A method for producing a bearing assembly for a gas turbine engine, comprising the following steps:
- providing a bearing assembly for a gas turbine engine, comprising:
- a bearing having a stator and a rotor rotatable relative thereto;
- a bearing bracket, which holds the bearing;
- a connecting element including an annular, projecting extension configured to be connected to a support structure of the gas turbine engine,
- a predetermined breaking device including at least one shear pin and being secured on the connecting element;
- and
- a clutch for transmitting a torque from a first clutch element connected in a fixed manner to the rotor of the bearing to a second clutch element supported on the bearing bracket;
- providing that the first and second clutch elements are spaced apart when the predetermined breaking device is intact and are brought into contact with one another by destruction of the predetermined breaking device via shearing of the at least one shear pin.
