949,527. Core constructions. MASCHINENFABRIK OERLIKON. Jan. 24,1962 [Feb. 15, 1961], No. 2691/62. Heading H2A. An arrangement for clamping a stack of core laminations 1, Fig. 5, for a dynamo-electric machine comprises end segments 4, bolts 2 which pass through the end segments externally of the stack, supports 7 on the segments, and, at each end, at least one straining device 8 which applies a force C to balance the reaction B produced by the laminations when the bolts are tightened. As described, the arrangement is applied to a stator cone and the straining device 8 comprises a ring, a second ring 9 being provided to exert an outward force. If the segments 4 abut each other in the form of an arch, this second ring may be. omitted. The supports 7 may be, as shown, in the form projections on the end segments, or alternatively in a modification, Fig. 10, the end segments 41 may be suitably shaped to co-operate with the rings 8, 9 and also to support the coil winding 10 attached to sliding blocks 12. Cooling passages may be provided through the end members and stack, Fig. 9 (not shown). |
