A turbine generator includes a plurality of spaced and parallel, transverse webs interconnected by plates to define an integral generator housing-base. Each transverse web in the generator section thereof includes a central, circular opening through which the generator rotor extends, and a plurality of apertures extending about the opening. Each transverse web further includes a walkway flange which, in association with the plates, forms a walkway, and also includes a superstructure lattice at the top thereof for supporting air cooling structure. A turbine is bolted to the integral generator housing-base, and is coupled to the generator rotor. Due to the integral generator housing-base, resonant vibrations of the base portion thereof at the generator operating frequency and at twice the generator operating frequency are eliminated, the weight and size of the turbine generator are reduced, and the turbine generator has greater structural integrity and rigidity.

Integral generator housing and base for a turbine generator

A support arrangement is disclosed for supporting an annular diaphragm in a turbine casing. The support arrangement allows the diaphragm to be vertically aligned with respect to the turbine casing and rotor and comprises in its most basic form the combination of a horizontally mounted bifurcated lug and a vertically mounted dumbbell shaped adjusting screw.
