Description:
Flexible membrane, as applied in
couplings and collars, refers to a bendy disc that has become highly popular because of torsional rigidity, predictable axial flexibility, and immunity from the environment. The flexible membranes were developed to replace the early designs that used radial spokes because they lacked radial flexibility. Because all the spokes contribute to torque transmission in the early models, a destructive overload can shear them and make the entire coupling to be considered ‘fail-safe'.
The new flexible membrane features a unique design where
bolts that attach to the membrane of the rigid members are eliminated. They are replaced by controlled resistance welding. Therefore, the attachment of the flexible membrane to the system spacers does not have bolts. Besides, the spokes on the outer end are welded to the ring that is bolted to the hub. This means that when using peripheral link couplings, there is no need for bolt tightening procedures. To see the full list of flexible membrane options, make sure to visit our page.
