Fig, 4-.-View in Energy Station Showing GWestinghouse-Parsons Steam Turbine at the shaft is not rigidly confined, as in the ordinary tiglit-flttingbearing, and this slight latitude of motion of the shaft is animportant element in the functioning of this machine. This mo-tion requires care of the gyration which the most perfect balanc-ing that is practicable does not eliminate. To counteract the end thrust on the spindle, due to the im-pact of the steam on the blades, the shaft is held in equili-brium by signifies of three balancing discs at the steam finish ofthe spindle contained in the turbine casing and marked in Fig5. These are created steam tight with the cylinder, and the enerators, Exciter Units and Switchboard.Worl<s of The Westinghouse Air Bral<e Co. diameter of each and every disc is created equal to the imply diameter ofthe corresponding drum carrying the blades. These disc cham-bers are connected by cores via the cylinder casting, withthe spaces occupied by the corresponding drums. In this wayt
