Summary:The turbine has, arranged between the rotor and a generator, a bevel gear transmission in a housing which is penetrated by the turbine shaft. A hydraulic servomotor for the blade adjustment is arranged on the side of the transmission housing facing away from the rotor. The cylinder of the servomotor is fastened on the transmission housing. The piston of the servomotor is connected in a rotationally fixed manner to a connecting rod which penetrates the turbine shaft coaxially, rotates at the rotor speed and is intended for the blade adjustment.

LA TURBINA TIENE UN REDUCTOR DE RUEDAS CONICAS DISPUESTO ENTRE EL RODETE Y UN GENERADOR, EN UN ALOJAMIENTO QUE ES ATRAVESADO POR EL ARBOL DE LA TURBINA. UN SERVOMOTOR HIDRAULICO PARA EL AJUSTE DE LAS PALAS ESTA DISPUESTO SOBRE EL LADO DEL ALOJAMIENTO DEL REDUCTOR ALEJADO DEL RODETE. EL CILINDRO DEL SERVOMOTOR ESTA SUJETO EN EL ALOJAMIENTO DEL REDUCTOR. EL EMBOLO DEL SERVOMOTOR ESTA UNIDO FIJO EN ROTACION CON UNA BIELA QUE ATRAVIESA COAXIALMENTE EL ARBOL DE LA TURBINA Y QUE GIRA CON EL NUMERO DE REVOLUCIONES DEL RODETE, PARA EL AJUSTE DE LAS PALAS.
