In recent years, due to the rapid development of the servo motor industry, the need to adapt to high-speed and high-precision control has been increasingly exaggerated. Couplings are increasingly used in machinery controlled by servo systems. In these fields, the coupling differs from general manufacturing machinery in that it must require the output to have a high following line relative to the input.  

Recently, couplings have been 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, the coupling must require its output to have a high degree of followability with respect to the input.  

Especially when used on machine tools that require high-frequency forward and reverse rotation, high-precision positioning, and high-speed rotation above 20000r/min, the coupling must have high rigidity and high elasticity that can withstand repeated torsional loads. Ability to limit fatigue to adapt to high-speed operation. Therefore, the coupling must have high torque rigidity, zero backlash, and elastic body to compensate the radial, axial, angular deviation, clockwise and counterclockwise rotation characteristics of the two shafts produced by the manufacturing machinery during the transmission process. .  

In the past, people only considered the coupling as a mechanical component. However, with the diversification of the use of the mechanical device using the coupling, in order to achieve higher functions, the familiarity with the coupling has changed from a simple Mechanical components are transformed into important mechanical elements that can influence the function of the entire mechanical system.

Therefore, it is becoming more and more difficult to meet the requirements of users solely by coupling manufacturers' independent product development. Now, it has become a trend that users and manufacturers work together to jointly develop couplings that meet the requirements of mechanical systems.
