Claw type surface to surface design, has the function of protecting, vibration and shock can produce effective damping and reduce the running in process. Claw type teeth two sleeve are offset in the circumferential direction, in the gap in a quincunx elastic body of involute. When small deviations in the installation, the elastic body avoids the stress concentration. Can effectively compensate the axial, radial and angular displacement. Column pin coupling elastomer old-fashioned type of large volume, shear effect, easy to damage, while the elastic body new claw type couplings only under the extrusion pressure, so it can withstand greater load, better wear resistance, longer service life. And both the level of installation, and can be installed vertical.
