Abstract

1444646 Cooling dynamo-electric machines BLACK & DECKER MFG CO 5 Aug 1974 [9 Aug 1973] 34394/74 Heading H2A A fan 39 has a stepped axial bore of which a first portion 47 is press-fitted to an armature shaft 34 and a second portion 52 is adhesively secured to an electrically insulating sleeve 36 fast with the shaft. The portion 52 of the fan bore is formed with a plurality of circumferentially spaced recesses 54, Fig. 2 (not shown), containing adhesive. The armature 20 shown is part of the electric motor of a hand drill.
