Description

Laufradnabe mit-verstellbaren-Schaufeln für Wasserturbinen. Die bisher bekannten Laufradkonstruktionen lassen die Möglichkeit zu, daß sowohl Wasser in die Nabe eintritt als auch das Schmiermittel oder Luft aus der Nabe austreten kann.Impeller hub with adjustable blades for water turbines. The so far known impeller designs allow the possibility that both water in the hub enters as well as the lubricant or air can exit the hub.

Beide Nachteile werden gemäß vorliegender Erfindung dadurch beseitigt, daß die Fuge, welche zwischen den drehbaren Schaufeln und ihrem Lager stets vorhanden ist, durch eine Dichtung abgedichtet wird. Diese Dichtung kann als Stopfbüchse oder Dichtungsring an beliebiger Stelle der Lagerung ausgeführt werden.According to the present invention, both disadvantages are eliminated by that the joint between the rotatable blades and their bearing is always present is sealed by a seal. This seal can be used as a stuffing box or Sealing ring can be carried out at any point in the bearing.
