| description | The invention belongs to the technical field of disassembling tools of gas turbine engines, and particularly relates to a method and tool structure for disassembling an interference fit structure of a turbine rotor. The tool structure comprises a hard cushion piece, an arc-shaped abutting piece and an ejection screw. The flange part of the arc-shaped abutting piece can abut against the outer edge of the shaft neck disc part of the turbine shaft. The ejection screw can abut against the front cushion face of the hard cushion piece. A flange plate part is arranged on the front side of the disc face of the turbine disc, and the flange plate back groove is formed between the flange plate part and the disc face of the turbine disc. The ejection screw is in threaded fit with the arc-shaped abutting piece and can push the arc-shaped abutting piece away from the hard cushion piece. According to the scheme, the tool structure and the disassembling method have the advantages of being simple, good in manufacturability, l |
