First Claim
Patent Images
1. A gas-cooled turbine generator comprising:
- a rotor having baffles arranged in rings and defining a plurality of gas zones;
a stator core having stator slots and a bore in which said rotor is received, and a plurality of air gap baffle assemblies arranged in segmented baffle rings within said stator slots and cooperating with said baffles on said rotor, each of the air gap baffle assemblies comprising at least one baffle segment and an individual locking cam cooperating with a respective baffle segment and unconnected to other locking cams of the baffle segments in the respective segmented baffle ring and locking the baffle segment relative to a stator slot at which the baffle segment is positioned without locking other locking cams of the baffle segments in the respective segmented baffle ring.

Abstract
A gas-cooled turbine generator includes a rotor having baffles arranged in rings and defining a plurality of gas cooling zones. A stator core has stator slots in a bore in which the rotor is received. A plurality of air gap baffle assemblies are arranged in segmented baffle rings in the stator slots and cooperate with the zone rings on the rotor. Each of the air gap baffle assemblies includes at least one baffle segment and an individual locking cam cooperating with a respective wedge of the baffle segment to lock the baffle segment relative to a stator slot at which the baffle segment is positioned such that prior baffle “trains” are no longer required.

10. A dynamoelectric machine comprising:
-
a substantially airtight casing adapted to be filled with a cooling gas;
a stator core disposed within the casing and including a cylindrical bore and longitudinal stator slots formed therein;
a rotor positioned for rotation within said cylindrical bore and forming an air gap between said rotor and stator core;
a plurality of baffles positioned on said rotor in a ring within said air gap and defining a plurality of gas zones for cooling; and
a plurality of air gap baffle assemblies arranged in segmented baffle rings within said stator slots and cooperating with said baffles on said rotor, each of the air gap baffle assemblies comprising at least one baffle segment and an individual locking cam cooperating with a respective baffle segment and unconnected to other locking cams of the baffle segments in the respective segmented baffle ring and locking the baffle segment relative to a stator slot at which the baffle segment is positioned without locking other locking cams of the baffle segments in the respective segmented baffle ring. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
