US 11,353,067 B2 · Elastomer series coupling damper for supercharger

Abstract

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger includes a first hub, a second hub, a central hub, and a plurality of coupler pins. The first hub can be mounted with the input shaft. The second hub can be mounted with the rotor shaft. The central hub can be disposed in between the first and second hubs. The central hub can have an elastomeric body that defines a series of passages therein. The passages can taper inwardly throughout and provide incremental dampening against the first and second plurality of pins. The plurality of coupler pins can be received in the central hub bores. The first and second plurality of pins can be received by the passages in the elastomeric body.

Dependent claims

A coupling assembly arranged between an input shaft and a rotor shaft of a supercharger, the coupling assembly comprising:

a first hub having a first plurality of openings therein, the first hub mounted for concurrent rotation with the input shaft;
a first plurality of coupling pins extending from the first plurality of openings;
a second hub having a second plurality of openings therein, the second hub mounted for concurrent rotation with the rotor shaft;
a second plurality of coupling pins extending from the second plurality of openings;
and
a central hub disposed intermediate the first and second hubs, the central hub having an elastomeric body that defines a series of passages therethrough, wherein the passages taper inwardly from a first end providing incremental dampening against the first and second plurality of pins, the first plurality of pins and the second plurality of pins are alternately received by the series of passages of the elastomeric body.
