Application of diaphragm coupling in precision machinery

Couplings are increasingly used in precision machinery controlled by servo systems, such as machine tools and semiconductor manufacturing machinery. In these fields, different from general manufacturing machinery, couplings require high precision, stable connection and high-quality standards, especially when used on working machines requiring high-frequency positive and negative rotation, high-precision positioning and high-speed rotation of more than 20000r/min, couplings must not only have high rigidity, but also have the ability to withstand repeated torsional loads with high elastic fatigue limit, so as to adapt to high-speed operation. Therefore, the coupling must have the characteristics of high torque rigidity, zero rotation clearance, elastomer compensation, radial, axial and angular deviations generated by the two shafts in the transmission process of manufacturing machinery, and equal clockwise and counterclockwise rotation characteristics. In the past, people only considered the coupling as a mechanical component. However, with the diversification of the uses of the mechanical devices using the coupling, in order to achieve higher functions, the familiarity with the coupling has changed from a simple mechanical component to an important mechanical element that can affect the function of the whole mechanical system. Our company specializes in the production of universal couplings

The coupling is used with various host products, and the surrounding working environment is relatively complex, such as temperature, humidity, water, steam, dust, sand, oil, acid, alkali, corrosive medium, salt water, radiation and other conditions, which is one of the important factors to be considered when selecting the coupling. For the working quality of high temperature, low temperature, oil, acid and alkali media, flexible couplings with general rubber as elastic element materials should not be selected, and flexible couplings with metal elastic elements should be selected, such as diaphragm couplings, serpentine spring couplings, etc.
