What should be paid attention to when disassembling the coupling
The coupling is related to the transmission and operation of the mechanical equipment, but if the coupling fails for a long time, it needs to be disassembled and replaced in time. The coupling disassembly process should pay attention to avoid damage to the mechanical equipment. What are the matters for the disassembly of the coupling? requires attention?
The installation and disassembly of the coupling must be performed in the correct process and manner to avoid damage to the coupling or equipment. The following coupling manufacturer Ying Feite will share with you the precautions of the disassembly process:
Coupling
1. If the coupling needs to be disassembled due to the failure of the coupling itself, it is recommended to perform a detailed inspection of the entire coupling, especially for the coupling that has been damaged, to find out the cause of the failure to avoid such failures in the future.
2. Before disassembling the 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.
3. When disassembling the coupling, the connecting bolt is usually disassembled 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 severely corroded bolt.
4. For bolts that have been rusted or have a lot of grease, it is recommended to spray the joint between the bolt and the nut with a solvent (such as rust loosening agent), so that the solvent can penetrate into the thread, so that it will be easier to disassemble.
5. Choose suitable tools for the disassembly of the connecting bolts. Otherwise, the outer or inner hexagonal bearing surface of the bolt will be slipped and damaged, and the disassembly will be more difficult.
6. After removing the connecting bolts, remove the plug pin and the spring ring, remove the motor, and loosen the two pressure plate nuts. At this time, the coupling may not be loosened, and two crowbars can be used to hold the end cover of the sealer facing towards Pry the coupling outside, and then remove the two pressure plate screws after the coupling is loosened, then the coupling and the half-round key can be removed.for reference only.
