  • Coupling for supercharger
    Patent number: 9803697
    Abstract: A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger can include a first coupling, a second coupling, a central hub and a plurality of coupler pins. The first coupling can be mounted for concurrent rotation with the input shaft. The second coupling can be mounted for concurrent rotation with the rotor shaft. The central hub can be disposed intermediate the first and second couplings. The central hub defines central hub bores therein. A plurality of coupler pins can be received in the central hub bores. A first plurality of elastomeric inserts can receive first portions of the plurality of coupler pins. A second plurality of elastomeric inserts can receive second portions of the plurality of coupler pins. The first and second elastomeric inserts can provide dampening between (i) the first coupling and the central hub and (ii) the second coupling and the central hub.
