The characteristics of diaphragm coupling installation and maintenance

       The characteristic of the diaphragm coupling is a bit like a bellows coupling. In fact, the way the coupling transmits torque is similar. The diaphragm itself is very thin, so it is easy to bend when the relative displacement load is generated, so it can withstand up to The deviation of 1.5 degrees, while producing lower bearing load in the servo system, the diaphragm coupling is often used in the servo system. The diaphragm has good torque rigidity, but it is slightly inferior to the bellows coupling. , Diaphragm coupling is very delicate, if it is misused or not installed correctly during use, it is easy to damage, so it is very necessary to ensure that the deviation is within the tolerance range of the normal operation of the coupling.

       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 couplings that are easy to assemble and disassemble, do not require maintenance, have a long maintenance period or are easy to maintain, replace wearing parts without moving the two shafts, and are easy to adjust the alignment. It is difficult for large machinery and equipment to adjust the alignment of the two shafts. You should choose to use durable and The couplings that are convenient to replace wearing parts. Metal elastic element flexible couplings generally have a longer service life than non-metal elastic element flexible couplings. Sealing and lubrication and the use of non-durable couplings will inevitably increase maintenance. Workload, for long-term continuous operation and high economic benefits, such as the high-speed end of the rolling mill transmission system of China's metallurgical enterprises, gear couplings are currently commonly used. Although the gear couplings theoretically transmit large torques, But it can only work under the conditions of good lubrication and sealing, and the sealing condition needs to be checked frequently, lubricating oil or grease is injected, the maintenance workload is large, the auxiliary working hours are increased, the effective working time is reduced, and the production efficiency is affected.
