Abstract

303,906. British Thomson-Houston Co., Ltd., (Assignees of Reist, H. G.). Jan. 13, 1928, [Convention date]. Yokes and carcass structures.-To prevent centrifugal stresses in a dynamo rotor from being transferred to the hub the pole pieces are carried on a ring which is connected to spokes &c. by means which allow of radial motion but prevent relative tangential movement. In the arrangement shown the ring 11 is built up of a number of overlapping arcuate plates secured by bolts. The spokes 14 are of a built up I cross section. Pins 16 secured to the ring 11 and sliding in holes 17<a> in angle brackets 17 secured to the spokes attach the ring 11 to the spokes. The whole is secured by keys 11<a> in keyways 17<b> in the brackets 17. The spokes 14 are secured to the hub 13 by annular plates 15 and bolts, as shown. In a modification the plates forming the ring 11 are at right angles to the axis and are carried by annular plates bolted to the hub, the pole-pieces, the ring and the annular plates being secured together by keys and keyways. The keys are driven home to such an extent as to subject the ring 11 to such an initial tension that it will not elongate sufficiently under centrifugal stress to unseat the keys. Specifications 22362/00 and 6486/03 are referred to.
