Abstract
In turbo-generators with hydrogen-cooled rotor windings, one-piece end casings are used to avoid complicated sealing positions. These end casings are strongly ribbed in a radial direction and present difficulties when installing the shaft seal (19). Furthermore, they do not permit any inspection openings in the ribbed end casing. Both have the final result of causing an increase in the machine length. Due to the pot-type design of the end casing (1) with a vertically extending channel-type recess (9) having a width greater than the rotor outer diameter, the assembly of the splert ring (19) is facilitated. The channel walls (7, 8) stiffen the end casing and provide niches which are accessible from the end face of the machine via inspection openings.
