The invention discloses a bearing assembling and decomposing device and method for a long-shaft part. The bearing assembling and decomposing device for the long-shaft part comprises an auxiliary support assembly surrounding the long-shaft part, and a bearing fixing assembly used for fixing a bearing penetrating in the long-shaft part from the small end of the long-shaft part, an assembling force application mechanism used for applying force to the large end face of the long-shaft part in the axial direction of the long-shaft part so as to propel the bearing assembling position of the long-shaft part to be in interference fit connection with the fixed bearing and a decomposition force application mechanism used for applying tensile force to the long-shaft part from the large end of the long-shaft part in the axial direction of the long-shaft part so as to propel the bearing assembling position of the long-shaft part to be separated out of the interior of the fixed bearing are arranged in the auxiliary support assembly. The mounting precision of the bearing is ensured; in the bearing assembling and decomposing process, no instantaneous acting force is generated, and the damage to the bearing and the long-shaft part is small. The bearing assembling and decomposing device is suitable for assembling and decomposing of the interference fit connection of various long-shaft parts in various aero-engines.
Description
Technical field [0001] The invention relates to the technical field of disassembly and assembly of aero engine parts, in particular to a bearing assembly and disassembly device for long shaft parts. In addition, the present invention also relates to a bearing assembly method for long shaft parts including the above-mentioned bearing assembly and disassembly device for long shaft parts. In addition, the present invention also relates to a bearing disassembly method for long shaft parts including the above-mentioned bearing assembly and disassembly device for long shaft parts. Background technique [0002] There are often some long shaft parts with very long axial length in aero engines, and support bearings need to be assembled at predetermined positions on them. The power turbine shaft assembly of a new turboprop engine has a shaft length of 1409mm and contains multiple bearing long interference surfaces (up to 25mm). Since the development of this model, the assembly of the bear...
