Abstract
Disclosed is an improved ceramic heat recovery wheel driven on a shaft containing a metal hub which may be driven without slippage between the wheel and the hub. The wheel includes a splined metal shaft which mates with the disk including a plurality of radially extending keys equi-angularly spaced about its circumference. The ceramic disk includes an equal plurality of radially extending keyways which mate with the keys. In one embodiment, the keys are situated on only one side of the bore of the ceramic disk and the keyways do not extend through the bore. On the opposite face of the disk, a retainer plate surrounds the shaft. An axial force is applied to the retainer plate for restraining movement of the wheel in the axial direction.
Claims9
A rotatable heat recovery wheel comprising:
- a round ceramic disk having a first face and a second face parallel thereto;
- a splined metal shaft mating with said disk for rotatably driving the same without slippage between said shaft and said disk;
- said splined shaft including a plurality of radially extending keys equi-angularly spaced thereabout;
- and
- said disk including an equal plurality of radially extending key ways in and open at at least one face thereof, but not extending to the other face thereof, and equi-angularly spaced thereabout for mating with said keys.
