The outer dimensions of the coupling, 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 middle. It is difficult for large machinery and equipment to adjust the two shafts. A coupling that is convenient to replace wearing parts.Flexible couplings with metal elastic elements generally have a longer service life than flexible couplings with non-metal elastic elements. Couplings that need to be sealed and lubricated and do not need to be used for a long time will inevitably increase 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 It can only work for a long time under the conditions of good lubrication and sealing, and it is necessary to frequently check the sealing condition and fill with 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.
In developed countries in the world, diaphragm couplings with long service life, no lubrication and maintenance have been widely 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 me are used, which not only has the advantages of the diaphragm coupling, but also has a good cushioning effect and a low price.
