Coupling removal

     When disassembling the coupling, the connecting bolts are usually removed first. Before disassembling the coupling, make some marks on the positions of the coupling components 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 coupling, generally disassemble the connecting bolt 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 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 remove.
