Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a screw compressor bearing dismounting device and a dismounting method. Background technique [0002] During the operation of the screw compressor, the cylindrical roller bearings at both ends of the rotor enable the rotor to achieve radial positioning, and bear the radial force during the operation of the compressor, reducing the load friction moment of the rotor during operation, so that the rotor rotates flexibly and has a certain The supporting accuracy and ensure the rotation accuracy of the rotor. [0003] Bearings need to be dismantled and replaced with new ones after a certain period of use, or during routine repair and maintenance, the bearings often need to be disassembled and replaced. The existing method for dismounting bearings generally uses a puller disassembly device, which has a complex structure, heavy weight, high cost, inconvenient operation, large site r...
