Abstract
Disclosed is a turbogenerator rotor, the rotor including a rotor body having two axial ends. The rotor further including a trunnion axially extending from each axial end of the rotor body. the rotor further including at least one baffle assembly provided on the circumference of the rotor body, the baffle assembly including at least one baffle member reversibly attached to the rotor body.
Claims14
A turbogenerator rotor, the rotor comprising:
- a rotor body having two axial ends;
- a trunnion axially extending from each axial end of the rotor body;
- and
- at least one baffle assembly provided on the circumference of the rotor body, the baffle assembly comprising at least one baffle member reversibly attached to the rotor body.
A turbogenerator, comprising a stator and a rotor, wherein an axially extending radial gap is provided between the stator and a rotor body of the rotor, the gap comprising two axial ends, the gap at at least one axial end being-partially constricted by a baffle assembly, while leaving a residual gap open, wherein at least one baffle member of the baffle assembly is reversibly attached to an outer circumference of the rotor body.
A method of furnishing a turbogenerator rotor with at least one baffle assembly, the method comprising:
- attaching the at least one baffle assembly on an outer circumference of a rotor body of the rotor of the turbogenerator, wherein:
- pre-manufacturing at least one baffle member, thereby providing the at least one pre-manufactured baffle member with the at least one baffle assembly, and reversibly attaching the at least one pre-manufactured baffle member on the outer circumference of the rotor body of the rotor.
A method of refurbishing a turbogenerator rotor, the method comprising
- detaching a used baffle assembly from an outer circumference of a rotor body of the rotor;
- providing at least one pre-manufactured baffle member to the baffle assembly;
- and
- attaching the at least one pre-manufactured baffle member of the baffle assembly on the outer circumference of the rotor body of the rotor,
- wherein attaching the at least one pre-manufactured baffle member comprises applying a reversible attachment method.
