Multi Disc Couplings are the multi-piece flexible shaft couplings, which are used for making connection between driving and driven pipes in mechanical power transmission constructions. They are utilized to counter the unavoidable misalignment and have advanced function to absorb the shock. These are functional as the scalloped-edged metal as well as multiple round elements which have limited flexibility and work without backlash as well as lubricant. They are finer than mechanically flexible couplings as these provide definite benefits over gear connectors in high-speed applications.
