What are the characteristics of a backlash-free elastic coupling

The following is XINLANCouplinganalysis:

The straight-tooth elastic body is installed under prestress, so that the surface of the elastic body bears a certain prestress, so that the rigidity of the coupling system is better.The elastic teeth can compensate the installation deviation and are supported by the built-in web in the radial direction, thereby avoiding excessive internal deformation during high-speed or accelerated rotation.The above features ensure the long-term stable operation of the coupling.The claw teeth of the shaft sleeve and the claw teeth of the elastic body are chamfered, which is convenient for "blind installation" during assembly.The small convex post on the tooth side of the elastic body is to reduce the contact area between the tooth side of the elastic body and the shaft sleeve.Ensuring the shaft sleeve spacing during installation can ensure the corrective ability of the coupling.The insertion force of the bushing during mating assembly depends on the hardness of the elastomer and the magnitude of the pre-stress.
