Shaft coupling development trend analysis

Shaft couplings are increasingly used in precision machines controlled by servo systems such as machine tools and semiconductor manufacturing machinery. In these fields, unlike general manufacturing machinery, the coupling must require that its output has a high followability relative to the input.
Especially when used on work machines that require high frequency forward and reverse rotation, high-precision positioning, and high-speed rotation of more than 20,000 r/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 the characteristics of high torque rigidity, zero slewing clearance, elastomer compensation for the radial, axial, angular deviation, clockwise and counterclockwise rotation characteristics of the two shafts produced by the manufacturing machine during transmission .
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 itself, in order to achieve higher performance, the familiarity of the coupling has been changed from a simple mechanical components are transformed into important mechanical elements that can control the function of the entire mechanical system.
Therefore, it is becoming more and more difficult to satisfy the requirements of users by relying solely on the product development of coupling manufacturers. Now, it has become a trend for users and manufacturers to work together to jointly develop couplings that meet the requirements of mechanical systems.
With the rapid development of automobile, construction machinery and other related fields, the technical requirements for the material, performance and strength of the supporting coupling have risen to a new level.
