<p>A furnace fan assembly includes a unique bearing arrangement which materially simplifies the fan structure while permitting the fan assembly to rotate at relatively high speeds without transmitting damaging vibrations to the fan mounting structure. The assembly includes a shaft with a fan wheel adjacent one end thereof. The shaft is journaled at its opposite end in a first bearing and a second bearing is positioned between the first bearing and fan wheel. The second bearing is mounted in a resilient support.</p> |
