XINLAN analyzes common fault maintenance of coupling

CouplingThe overall dimensions, that is, the maximum radial and axial dimensions, must be within the installation space allowed by the machine and equipment.Choose a coupling that is convenient for assembly and disassembly, does not require maintenance, has a long maintenance period or is convenient for maintenance, does not need to move the two shafts to replace the wearing parts, and is easy to adjust the centering.

　　It is difficult to adjust the alignment of the two shafts of large machinery and equipment, so you should choose the coupling that is durable and easy to replace the wearing parts.Metal elastic element flexible couplings generally have a longer service life than non-metal elastic element flexible couplings.The need to seal and lubricate and the use of undurable couplings will inevitably increase the maintenance workload.For occasions with long-term continuous operation and high economic benefits, such as the high-speed end of the rolling mill transmission system of my country's metallurgical enterprises, gear couplings are currently commonly used. Although gear couplings theoretically transmit large torque, they must be Durable work can only be done under conditions of good lubrication and sealing.In addition, it is necessary to frequently check the sealing condition and inject lubricating oil or grease. The maintenance workload is large, which increases the auxiliary working hours, reduces the effective working time, and affects the production efficiency.Developed countries in the world have generally selected diaphragm couplings with long service life and no lubrication and maintenance to replace drum-shaped gear couplings, which not only improves economic efficiency, but also purifies the working environment.In the rolling mill transmission system, the flexible movable pin coupling and the sector-shaped elastic coupling developed by our country are selected, which not only has the advantages of the diaphragm coupling, but also has a good cushioning effect and a cheaper price.
