摘要： Fixing device for a shaft sealing ring and transmission device having such a device. A fixing device for a shaft sealing ring is disclosed. Furthermore, a transmission device is disclosed, wherein the transmission device comprises a first transmission part which is rotatable about an axis of rotation, a sealing seat formed in the first transmission part, a shaft sealing ring fitted in the sealing seat and a second transmission part which extends through the first transmission part and the shaft sealing ring and is rotatable about the axis of rotation. A sealing lip is formed on the shaft sealing ring, the sealing lip engaging with an outer surface of the second transmission part and being pretensioned by a spring element arranged on the shaft sealing ring. The transmission device also has a fixing device for the shaft sealing ring.

摘要： A gerotor pump arrangement for extracting hydraulic fluid from a transmission housing of a transmission. A first gerotor set has a first inner rotor and a first outer rotor, and a second gerotor set has a second inner rotor and a second outer rotor. The first gerotor set forms a hydraulically drivable drive side of the gerotor pump arrangement, and the second gerotor set forms a pump side, driven by the first gerotor set, wherein the first and second inner rotors are rotationally fixedly mounted on a common shaft which is rotatable about a rotational axis. A transmission with such a gerotor pump arrangement is also disclosed.
