Flexible diaphragm couplings are increasingly used in machinery controlled by servo systems

The installation error of the elastic diaphragm coupling should be strictly controlled, usually requiring that the installation error should not be greater than half of the allowable compensation amount. Pay attention to check the alignment of the connected two shafts after operation, the relative displacement should not be greater than the allowable compensation amount, and the relative displacement should be reduced as much as possible when used, which can effectively extend the service life of the connected mechanical or elastic diaphragm coupling.

For couplings with lubrication requirements, such as gear couplings, it is necessary to regularly check the oil amount, quality and sealing condition of the lubricating oil, and if necessary, it should be supplemented or replaced. For the elastic diaphragm coupling on high-speed rotating machinery, it is generally subject to dynamic balance test and assembled according to the mark. The weight difference between the connecting bolts is strictly limited and cannot be replaced at will.

Diaphragm flexible couplings are increasingly used in machinery controlled by servo systems. Unlike ordinary manufacturing machinery in these fields, the output of diaphragm couplings is required to have a high dependence on the input. Couplings are increasingly used in machine tools and semiconductor systems, manufacturing machinery and other precision machinery controlled by servo systems.

The motor output shaft has a bearing in the motor connection end face, equivalent to a cantilever beam, is not able to withstand the bending moment, if directly connected to the motor shaft sprocket, in the working process, due to the tension of the chain, will give the motor shaft a large bending moment, so that the motor shaft bearings do not work properly, the shaft of the sprocket will be supported on another frame, while also requiring the coaxiality of the assembly.
