Abstract
1,231,692. Axial-flow fans. ETUDES TECHNIQUES ET REPRESENTATIONS INDUSTRIELLES. March 20, 1969 [March 29, 1968] , No. 14705/69. Heading F1C. [Also in Division H2] An axial fan comprises a casing 1 carrying a force-fitted stationary shaft 12 and a stator 9 of a squirrel cage motor whose internal rotor 35 has short-circuit end rings 36, 37 receiving ball bearings 13 fitted between them and the shaft 12. The rings are of aluminium and are cast integrally with the rotor. The inner ball races are located by shoulders and a spring on the shaft, Fig. 3 (not shown) and the outer races are bonded directly to the rings or to bushing 15 secured in position during casting of the rotor. The impeller 3 is fitted directly to the rotor and receives a sealing disc 21.
