ABSTRACT:
A buffing wheel hub device comprising telescoping male and female units having axially extending finger members supporting a plurality of buffing wheels thereon between end plates of said units to compactly support and drive said wheels rotatably by an arbor on which said units and buffing wheels are secured and mounted for rotation. The finger members each have arbor bore adjacent portions defined by radially inclined surfaces tapering toward each other and radially extending stems of substantially lesser transverse cross-sectional thickness than the transverse cross-sectional thickness of the bore adjacent portions, whereby flexing of the finger members under centrifugal force is generated, permitting improved engagement with the buffing wheels supported thereon. The end plates have openings transversely therethrough for passage of ambient cooling air into said hub and about said finger members. The finger members of one said unit are relatively shorter than the finger members of the other said unit.
