ABSTRACT:
A large turbine generator is provided with a stator end winding assembly that includes a large conical member outside the coils which is joined by banding with adjusting rings radially inside the coils, with an adjusting means for each banding location that includes a wedge extending through an aperture in a portion of the adjusting ring that extends away from the coil and having a fastener that is joined to the wedge so that upon the tightening of the fastener, the wedge will be forced in the axial direction bearing against the banding and hence tightening it; and in addition, the conical member is provided with projections serving as torque splines that fit within apertures of the core so as to prevent its rotational movement in operation.
