Axial spacer for a rotational assembly
DCFirst Claim
1. A one-piece monolithic axial spacer for a rotational assembly, comprising:
- a body having an outer ring, wherein the outer ring includes a top surface and a bottom surface, an inner ring, wherein the inner ring includes a top surface and a bottom surface, and further wherein the inner ring is spaced apart from the outer ring, a plurality of reinforcing members extending between the inner ring and the outer ring, and a plurality of web members extending between adjacent reinforcing members and the inner and outer ring;
means for attaching the spacer to a rotational assembly, the attaching means comprising an opening extending through at least a plurality of the plurality of reinforcing members; and
means for centering the spacer relative to the rotational assembly, wherein the centering means comprises a centering flange disposed on an inner surface of the inner ring, wherein the centering flange includes a top surface and a bottom surface, and wherein the centering flange is offset relative to the inner ring such that the bottom surface of the flange is positioned between the top and bottom surface of the inner ring and the top surface of the flange is positioned above the top surface of the inner ring, and such that a step is formed by the centering flange relative to the inner ring.

Abstract
An axial spacer for a rotational assembly comprising a body, a rotational assembly attaching member and a centering member. The body comprises an outer ring, an inner ring and a plurality of reinforcing members extending between the inner ring and the outer ring. The reinforcing members each comprise an annular reinforcing rim extending from the outer ring and a connecting beam extending from the annular reinforcing rim to the inner ring. A plurality of web members extend between adjacent reinforcing members and the inner and outer ring, to, in turn, substantially couple adjacent reinforcing members with the inner and outer ring therebetween. The attaching means comprises an opening extending through at least a plurality of the plurality of reinforcing members. The centering member centers the spacer relative to the rotational assembly.
