Abstract
A tool for removing a component from a turbomachine is provided. The tool includes a body having an alignment portion and a connection portion. The alignment portion defines a longitudinal axis and a cross sectional shape complementary to a slot defined in a rotor wheel of the turbomachine. When the tool is positioned in the slot, the connection portion is configured to contact the component. The tool additionally includes a force section connected to the body and configured to transfer a force to the connection portion in a direction substantially parallel to the longitudinal axis of the alignment portion.
Claims20
A tool for removing a component of a turbomachine, comprising:
- a body, the body comprising
- a connection portion configured to contact the component;
- and
- an alignment portion defining a longitudinal axis and a cross-sectional shape, the cross-sectional shape being a dovetail shape complementary to a slot defined in a rotor wheel of the turbomachine;
- and
- a force section connected to the body and configured to transfer a force to the connection portion of the body in a direction substantially parallel to the longitudinal axis of the alignment portion.
A method for removing a component of a turbomachine, comprising:
- positioning a tool into a slot defined in a rotor wheel of the turbomachine such that a
- connection portion of the tool contacts the component, the tool defining a longitudinal axis;
- applying a force to a force section of the tool, the force being transferred from the force section to the connection portion in a direction substantially parallel to the longitudinal axis of the tool;
- applying the force to the component of the turbomachine using the tool.
An assembly for removing a component in a turbomachine, comprising:
- a first rotor wheel, the component being slidably coupled to the first rotor wheel;
- a second rotor wheel positioned adjacent to the first rotor wheel, the second rotor wheel defining a slot;
- and
- a removal tool comprising
- a body, the body comprising
- a connection portion in contact with the component;
- and
- an alignment portion positioned in the slot defined in the second rotor wheel, the alignment portion defining a longitudinal axis and a cross-sectional shape, the cross-sectional shape being complementary to the slot defined in the second rotor wheel;
- and
- a force section connected to the body and configured to transfer a force to the connection portion of the body in a direction substantially parallel to the longitudinal axis of the alignment portion.
