Abstract
A steam turbine-driven generator for generating electric power is comprised of an electric generator having a vertical shaft journalled for rotation between bearings contained in a generator housing. An axial flow impulse turbine wheel with peripheral vanes is secured to an unsupported upper end of the shaft protruding from the top of the generator housing. The turbine wheel is enclosed within a turbine housing secured to the top of the generator housing. The turbine housing includes an inlet and an outlet for accommodating a through flow of steam, with internally arranged nozzles for directing the steam flow against the vanes of the turbine wheel.

A steam turbine-driven generator for generating electric power, comprising:
- an electric generator having a vertical shaft journalled for rotation between bearings contained in a generator housing, said vertical shaft having an unsupported upper end protruding from the top of said generator housing;
- an axial flow impulse turbine wheel having a central hub and peripherally arranged vanes;
- clamping means for securing the central hub of said turbine wheel to the unsupported upper end of said vertical shaft;
- a turbine housing supported by said generator housing, said turbine housing defining a chamber containing the upper end of said vertical shaft and the turbine wheel secured thereto, said turbine housing having an inlet and an outlet positioned to accommodate a downward flow of steam through said chamber;
- and
- nozzle means for directing said steam flow against the vanes of said turbine wheel to rotatably drive said vertical shaft.
