How to disassemble the plum blossom coupling

　　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 clearly marked and cannot be mistaken.

　　When disassembling the torx 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.Removal of connecting bolts Choose suitable tools, because the bearing surface of the bolt's outer hexagon or inner hexagon has been slipped and damaged, and it will be difficult to disassemble.For bolts that have been rusted or have a lot of grease, solvents (such as rust loosening agent) are often used to spray the joints between the bolts and the nuts, so that the solvent can penetrate into the threads, so that it will be easy to disassemble.If the bolts cannot be removed, the heating method can be used, and the heating temperature is generally controlled below 200°C.By heating, the gap between the nut and the bolt is enlarged, the rust is also easy to fall off, and the bolt disassembly becomes easier.If none of the above methods work, only damage the bolts, cut or drill the bolts, and replace them with new bolts when assembling.

　　The new bolts have the same specifications as the original bolts. The new bolts used for high-speed equipment couplings are also weighed so that the new bolts have the same weight as the connecting bolts on the same set of flanges.Due to the failure of the plum blossom coupling itself, it needs to be disassembled. First, the entire coupling must be carefully inspected (especially for the damaged coupling), and the cause of the failure should be found out.

　　Cleaning, cleaning and quality assessment of all parts of the plum blossom coupling is an extremely 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 ones are new parts that should be scrapped.
