Abstract
Abstract A contact wheel hub assembly for a surface finishing machine is provided with cooling fluid conduits to remove heat generated by the contact wheel and a cooperating abrasive belt during grinding, sanding, buffing and similar finishing operations. The contact wheel of the assembly is composed of a rotatable support sleeve and a contact wheel tread over which the abrasive belt moves in driving contact. The support sleeve is provided with a plurality of axially extending internal grooves which serve as conduits for a cooling fluid supplied to the wheel during a finishing operation. The cooling fluid exhausts to the ambient environment through the grooves to remove heat generated by the finishing operation from the sleeve and contact wheel tread.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
78 words
A fluid cooled hub assembly adapted for mounting the resilient tread of a contact wheel including: a rotatable support member having a generally cylindrical outer tread mounting surface and a coaxial inner surface, both the inner and outer surfaces extending coaxially with the axis of rotation of said member and a cooling fluid conduit defined by a groove extending in the axial direction along at least one portion of said inner surface beneath the outer tread mounting surface.
Claim 2
Dependent Claim
78 words
A fluid cooled hub assembly adapted for mounting the resilient tread of a contact wheel including: a rotatable support member having a generally cylindrical outer tread mounting surface and a coaxial inner surface, both the inner and outer surfaces extending coaxially with the axis of rotation of said member and a cooling fluid conduit defined by a groove extending in the axial direction along at least one portion of said inner surface beneath the outer tread mounting surface.
Claim 3
Dependent Claim
70 words
A fluid cooled hub assembly as defined in claim 1 wherein the rotatable support member has an axial end face at one end, the inner and outer surfaces of the member extending axially of the member to the axial end face; and the inner surface has a plurality of the grooves extending axially of the member to the axial end face to define a plurality of the cooling fluid conduits.
Claim 4
Dependent Claim
91 words
A fluid cooled hub assembly as defined in claim 1 wherein said rotatable support member is a support sleeve; and wherein a mounting shaft extends coaxially within said support sleeve and a plurality of axially spaced Journal bearings are interposed between said mounting shaft and said support sleeve, said mounting shaft having a cooling fluid conduit extending axially along at least a portion of its length and at least one generally radial port extending therefrom to provide communication between its conduit and the grooves in said support sleeve between said bearings.
Claim 5
Dependent Claim
58 words
A fluid cooled hub assembly as defined in claim 3 further comprising a hub support arm having a mounting aperture for said mounting shaft and a cooling fluid conduit opening into the mounting aperture, said mounting shaft being positioned in the mounting aperture and having a port interconnecting the cooling fluid conduits of said shaft and said arm.
Claim 6
Dependent Claim
122 words
A fluid cooled contact wheel assembly comprising: a rotatable support sleeve having an external tread mounting surface and a generally cylindrical internal surface defining a plurality of fluid conducting grooves extending axially along the sleeve; an annular tread member formed from a resilient material mounted to the external tread mounting surface of the support sleeve; a support shaft extending coaxially within the support sleeve and having a cooling fluid conduit extending from one end portion of the shaft to a radial port exposed to the axially extending grooves on the internal surface of the sleeve; and a plurality of journal bearings interposed between the support shaft and support sleeve and axially spaced along the shaft at opposite sides of the radial port.
Claim 7
Dependent Claim
122 words
A fluid cooled contact wheel assembly comprising: a rotatable support sleeve having an external tread mounting surface and a generally cylindrical internal surface defining a plurality of fluid conducting grooves extending axially along the sleeve; an annular tread member formed from a resilient material mounted to the external tread mounting surface of the support sleeve; a support shaft extending coaxially within the support sleeve and having a cooling fluid conduit extending from one end portion of the shaft to a radial port exposed to the axially extending grooves on the internal surface of the sleeve; and a plurality of journal bearings interposed between the support shaft and support sleeve and axially spaced along the shaft at opposite sides of the radial port.
Claim 8
Dependent Claim
70 words
The fluid cooled contact wheel assembly according to claim 5 further including a support arm having a mounting aperture accommodating said one end portion of the support shaft and a cooling fluid conduit extending along the arm to the mounting aperture, said one end portion of the support shaft having fluid porting communicating the fluid conduit of the shaft with the fluid conduit of the arm at the mounting aperture.
