Abstract
Disclosed is a novel mounting structure for a rotatable heat exchanger, sometimes known as a heat recovery wheel. The mounting structure includes a hub portion on at least one side of the wheel and axially aligned therewith with at least three radially movable shoes situated within the bore of the wheel and coupled to the hub portion. A torsion bar is connected to the hub which applies equal radial forces to each of the shoes whereby the shoes are biased against the wheel at the periphery of the bore and equally displaced from the axis of the wheel. The aforementioned arrangement provides a mounting which is self centering and yet which permits differential radial expansion of a metal hub with respect to a ceramic wheel.

A mounting device for a heat recovery wheel of the type having a ceramic disk with a central bore therein comprising:
- a first hub portion on one side of said wheel and axially aligned therewith;
- at least three radially movable shoes situated in said bore, and coupled to said first hub portion, said shoes being equiangularly spaced about the periphery of said bore;
- and
- cam-driven means for applying equal radial forces to each of said shoes whereby said shoes are biased against said wheel at the periphery of said bore and equally displced from the axis of said wheel.
A rotatable recovery wheel comprising:
- a round ceramic disk having a central bore therein;
- a first hub portion on one side of said disk at said bore, said first hub being axially aligned with said disk;
- at three radially movable shoes situated in and equiangularly spaced about said bore and coupled to said first hub potion;
- and
- cam-driven means for applying equal radial forces to said shoes whereby said shoes are biased against said disk and equally displaced from said axis upon rotation thereof.
