Abstract
A bulb type turbine generator in which upper and lower stay vanes house upper and lower oil tanks. The upper oil tank is connected to the rotary shaft bearing portion of the generator through an oil conduit and the lower tank is connected to a bearing portion. The oil conduits are disposed in the interior of the outer case so that oil passing through is cooled by the fluid flow. The outer casing together with the upper and lower stay vanes are divided to facilitate transportation and installation.

In a bulb type tubular generator having an outer casing, a generator housed in an inner bulb type casing within the outer casing, and a turbine coupled to said generator and protruding in a flow space between said inner and outer casing, the improvement comprising;
- generator lubrication means disposed inside of the outer casing, means for mounting said inner casing in a spaced relationship from said outer casing, lubrication reservoir means disposed in said mounting means, said mounting means comprising a first set of stay vanes disposed on opposite sides of said bulb, and wherein said lubrication reservoir means comprises first and second chambers disposed in said first set of stay vanes.
In a bulb type of tubular generator having an outer casing, a generator housed in an inner bulb type casing within the outer casing, and a turbine coupled to said generator and protruding in a flow space between the inner and outer casings, the improvement comprising;
- said outer casing being diametrically split to divide the same into first and second compatible component parts;
- and further comprising first and second sets of stay vanes coupling said inner casing to said outer casing, said sets of stay vanes being disposed on opposite sides of said diametric split, wherein said first set of stay vanes include means for generator lubrication including first and second lubrication chambers disposed therein.
