In recent years, due to the rapid development of the servo motor industry, the need for high-speed and high-precision control has been increasingly emphasized. Couplings are increasingly used in machinery controlled by servo systems. The difference between these fields and general manufacturing machinery is that the output must have a high followability relative to the input, so that it can operate with zero clearance. The need to adapt to high-speed and high-precision control is increasingly emphasized. In order to rapidly strengthen the development of my country's coupling industry, it is important for coupling factories to cooperate and promote each other.

Couplings are more and more widely used:

In recent years, couplings have been increasingly used in precision machinery controlled by servo systems such as machine tools and semiconductor manufacturing machinery. In these fields, unlike general coupling manufacturing machinery, the output must be required to have a high followability with respect to the input.

Coupling positioning and speed refinement degree:

For working equipment that requires high-frequency forward and reverse rotation, high-precision positioning, and high-speed rotation with a speed higher than 20000r/min, the coupling must not only have high dynamic balance, but also must be able to withstand repeated torsional loads. The ability of high elastic fatigue limit to adapt to high-speed frequent positive and negative rotation. Therefore, in addition to high torque rigidity and good dynamic balance performance, the coupling must also have zero rotation clearance and elasticity to compensate the radial, axial, and angular deviations of the two shafts during the installation process of the mechanical equipment to ensure The characteristics of clockwise and counterclockwise rotation are the same.

As people’s understanding of couplings has changed, couplings have become more and more important:

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 coupling, in order to achieve higher performance, the understanding of the coupling has changed from a simple The mechanical components are transformed into important mechanical elements that can influence the performance of the entire mechanical system.
