XINLAN analyzes the method of disassembling the plum blossom coupling

two toPlum couplingIf you need to disassemble due to its own failure, you must first carefully inspect the entire coupling (especially for the damaged coupling), and find out the cause of the failure.
    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 must be weighed, and the markings must be clear and not to be mistaken.
    When removing 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.The disassembly of the connecting bolts must be done with suitable tools, because the bearing surface of the bolt's outer hexagon or inner hexagon has been slipped and damaged, and the disassembly will be more difficult.For bolts that have been rusted or with a lot of grease stains, solvents (such as rust loosening agents) are often used to spray the joints between the bolts and the nuts, so that the solvent can penetrate into the threads, which 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 must have the same specifications as the original bolts. The newly replaced bolts used for high-speed equipment couplings must also be weighed so that the new bolts have the same weight as the connecting bolts on the same set of flanges.

    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 the comparison of 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.

    In the process of disassembling the plum coupling, the most difficult job 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 hub, and the right-angle hooks of each leg of the puller should be properly combined with the rear side of the hub, so that no slippage will occur when you apply force.This method is only used for the disassembly of hubs with relatively small interference. For hubs with relatively large interference, heating methods are often used, or at the same time with hydraulic jacks for disassembly.
