Plug device for gas turbine engine shaft

摘要

A device for plugging an axially-aligned bore in a shaft of a gas turbine engine comprises a plug. A sealing body of the plug is sealingly received in a bore of the shaft. Legs project from the sealing body and are displaceable between a normally contracted position in which the legs are radially inward relative to a periphery of the bore, and a deployed position in which the legs project radially outward and engage with shaft projections within the bore of the shaft. A wedge is operatively engaged to the plug for movement of the wedge relative to the plug. The wedge comprises a portion in operative contact with the legs of the plug unit to displace the legs between positions as a response to movement of the wedge. A gas turbine engine and a method for plugging a shaft are provided.

1. A device for plugging an axially-aligned bore in a shaft of a gas turbine engine, comprising:
a plug comprising a sealing body shaped to be sealingly received in a bore of the shaft, and legs projecting from the sealing body and being displaceable between a normally contracted position in which the legs are radially inward relative to a periphery of the bore, and a deployed position in which the legs project radially outward and are adapted to engage with shaft projections within the bore of the shaft; a wedge operatively engaged to the plug for movement of the wedge relative to the plug, the wedge comprising a portion in operative contact with the legs of the plug unit to displace the legs between said positions as a response to said movement of the wedge; and wherein the sealing body is an annular body, and the wedge is matingly engaged in the annular body, at least one seal being between the wedge and the annular body.
