Problems solved by technology

[0002] In electromechanical equipment, there are ring-shaped parts such as bearings, gears, couplings, and motor wind fins. These ring-shaped parts are tightly sleeved on the shaft of the electromechanical equipment. , A large number of these ring-shaped parts are disassembled from the shaft. Since the cooperation between the ring-shaped parts such as bearings, gears, couplings, motor wind fins and the shaft is a transition fit, it is very difficult to disassemble. , sometimes it is disassembled with an ordinary disassembler, because there are many types of electromechanical equipment, and the shafts of different equipment and the ring-shaped parts on the shaft vary greatly in size, shape and position, and ordinary disassemblers cannot be well adapted to electromechanical equipment. The above-mentioned disassembly work during equipment maintenance

In the prior art, there is no combination that is convenient to use during the maintenance of electromechanical equipment and is suitable for disassembling bearings, gears, couplings, motor wind fins and other circular parts of different sizes, shapes and positions on the shafts of different electromechanical equipment. In the maintenance process of electromechanical equipment, when installing and disassembling bearings, gears, couplings, motor wind fins and other circular parts, because there is no suitable disassembler, maintenance personnel sometimes use hand hammers, sled rods, etc. Hard knocking and prying tools such as tools often cause damage to electromechanical equipment or components
