Claims20
An apparatus for replacing a bearing coupled to a tie rod of a gas turbine, the tie rod being surrounded by an internal casing and extending through central axes of the plurality of compressor rotor disks and through central axes of the plurality of turbine rotor disks, the apparatus comprising:
- an insertion part configured to be coupled to an end of the tie rod extending toward the turbine rotor and to cover the end of the tie rod;
- and
- a support part configured to be installed below the insertion part, the support part including
- a moving part to move the tie rod upward and downward while supporting the insertion part, and
- a support plate removably attached to a mounting member configured to be seated in a drain groove formed in the internal casing.
An apparatus for replacing a bearing coupled to a tie rod of a gas turbine, the tie rod extending through central axes of the plurality of compressor rotor disks and through central axes of the plurality of turbine rotor disks the tie rod and including an outer circumferential surface and a distal end having an axially facing surface communicating with the outer circumferential surface, the apparatus comprising:
- an insertion part configured to be coupled to the tie rod toward the turbine rotor, the insertion part including an inner surface configured to cover the axially facing surface of the distal end of the tie rod and to cover at least a portion of the outer circumferential surface extending from the distal end;
- and
- a support part configured to be installed radially outward from the outer circumferential surface of the tie rod so as to be disposed below the insertion part, the support part including a moving part to move the tie rod upward and downward while supporting the insertion part.
