Our company's cleaning, cleaning and quality assessment of all parts of plum coupling products is an important task after the coupling is disassembled.The evaluation of components refers to comparing the existing conditions of the size, shape and material properties of each component with the quality standards determined by the component design to determine which components can continue to be used and which components should be used. After repairing, which parts belong to the parts that should be scrapped and updated.

　　Before disassembling the plum blossom coupling, make some marks on the coordinated positions of the various parts of the coupling for reference when reassembling.For couplings used in high-speed machines, the connecting bolts have been weighed and marked clearly and cannot be mistaken.

　　When removing the coupling, the connecting bolt is usually removed first.Because a layer of grease, corrosion products and other deposits are deposited on the surface of the thread, the bolt is not easy to disassemble, especially for the heavily corroded bolt, it is very difficult to disassemble.Choose suitable tools for the disassembly of the connecting bolts, because the bearing surface of the outer hexagon or inner hexagon of the bolt has been slipped and damaged, and the disassembly will be more difficult.For bolts that have been rusted or have a lot of grease, solvents (such as rust loosening agents) are often used to spray the joints of the bolts and nuts to allow the solvent to penetrate into the threads, which will be easy to disassemble.

　　In the process of disassembling the plum coupling, the difficult task is to remove the hub from the shaft.For the hub of the coupling, a three-legged puller or a four-legged puller is generally used for disassembly.The selected puller should match the outer dimensions of the wheel hub, and the right-angle hooks of each foot of the puller should be properly combined with the rear side of the wheel hub, so that the imagination of slippage will not occur when exerting force.This method is only used for disassembly of hubs with relatively small interference. For hubs with relatively large interference, heating methods are often used or combined with hydraulic jacks for disassembly.
