Flexibility for the connection between turbine and pinionis obtained by the use of a flexible coupling, and in addi-tion to this a slender turbine shaft extension is carried This type of reduction gear has been under process ofdevelopment during a considerable period by the Westing-house Machine Company. The first installations were madefor the propulsion of ships, but later the possibilities ofapplication to electric generation became apparent andabout two years ago the first turbine driving a direct-current generator through reduction gearing was Geared D.

Turbo-Generators—General View of RigidlyAligned Type of Gear, Showing Casing andOil Piping through the hollow pinion shaft, driving it through a con-nection at the end opposite to the turbine, and through itsflexibility permitting wide variations in alignment. Verticaladjustment of gear and pinion is effected through varia-tions in the quantity of oil contained in the cylinders overthe pistons.

The distinctive feature of the new gear is the main-tenance of correct tooth contact whatever the exigenciesof opera
