Abstract
1474439 Supporting end windings in dynamo-electric machines BBC BROWN BOVERI & CO Ltd 1 July 1974 [2 July 1973] 29080/74 Heading H2A The rotor end winding of a high speed electrical machine is held in position by an end bell 1 comprising inner and outer rings 1À1, 1À2 surrounding the end winding, the outer ring being shrunk on to the inner ring and the inner ring being shrunk on to the end of the rotor body, the inner ring being locked in position to prevent axial movement relative to the rotor body. The locking is performed by a bayonet ring 2 whichis rotated until teeth 2.1, 2.2 on its inner surface are axially aligned with aligned teeth 3.1 and 1.3 on the rotor body and inner ring 1.1 respectively. The inner ring is made of high strength easily machinable material such as non-magnetic steel. The outer ring is of higher strength than the inner ring and has a high strength to weight ratio, suitable materials being titanium and carbon fibre reinforced material.
