Connection stability of diaphragm coupling

　　Diaphragm couplings are increasingly used in precision machinery controlled by servo systems, such as machine tools and semiconductor system manufacturing machinery.In these fields, unlike general manufacturing machinery, diaphragm couplings require high precision, stable connection, and high quality standards, especially for high-frequency forward and reverse rotation, high-precision positioning, and high-speed rotation above 20000r/min. When used on a machine tool, the diaphragm coupling must not only have high rigidity, but also have the ability to withstand repeated torsional loads and a high elastic fatigue limit to adapt to high-speed operation.Therefore, the diaphragm coupling must have high torque rigidity, zero rotation clearance, and elastic body compensation for the radial, axial, angular deviation, clockwise and counterclockwise rotation characteristics generated by the two shafts during the transmission process of the manufacturing machinery. Equality characteristics.In the past, people only considered the coupling as a mechanical part. However, with the diversification of the use of the mechanical device using the diaphragm coupling, in order to achieve high performance, the understanding of the diaphragm coupling has been changed from A simple mechanical component is transformed into an important mechanical element that can influence the function of the entire mechanical system.
