Spring coupling connects two shafts through elastic spring elements, can buffer vibration damping, compensation of axial / radial / angular deviation, compact structure, easy to install, suitable for high speed, shock load mechanical transmission scenarios (such as electric motors, pumps, fans, etc.), can effectively reduce the vibration of the shaft system and torsional deformation, is the commonly used parts of the mechanical transmission to achieve a flexible connection.
