Installation and maintenance of coupling

The radial and axial dimensions of the coupling should be within the installation space allowed by the machine and equipment. Choose a coupling that is convenient for assembly and disassembly, no maintenance, long maintenance period or easy maintenance, replacement of wearing parts without moving the two shafts, and easy centering adjustment. Shaft.

It is difficult to adjust the alignment of the two shafts of large machinery and equipment, so you should choose a coupling that is durable and easy to change wearing parts.Flexible couplings with metal elastic elements generally have a longer service life than flexible couplings with non-metal elastic elements.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,

Gear couplings are commonly used in the high-speed end of rolling mill transmission systems in metallurgical enterprises in my country. Although gear couplings theoretically transmit large torque, they can only work for long periods of time 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 working time, and affects the production efficiency.Diaphragm couplings with long service life and no need for lubrication and maintenance have been commonly used to replace drum-shaped gear couplings, which not only improve economic efficiency, but also purify 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 low price.
