Abstract
A mechanical clamping assembly and the method of its application for use on the stator end windings of large steam turbine generators is provided that can be fit in the mid-involute region of the end winding, including any existing machines as may be in use in the field as well as in original manufacture. The invention maintains pressure contact between coils and strain blocks and eliminates the freedom of the coils to vibrate relative to the total end basket assembly. The method comprises steps of forming a loop of impregnated banding material that extends through apertures of support blocks that span a pair of adjacent top and bottom coils, inserting pins in the ends of the loop, twisting a pin, curing the banding material, pulling on a pin to pretension the banding and shimming the pulled pin so that upon its release a tight assembly is provided.
