Abstract (en)

[origin: EP2647793A1] The motor has a shaft (2) rotatably mounted at housing (1) by a roller bearing assembly with axially spaced roller bearings (3,4) arranged at a bearing space (47). A rotor ring is equipped with inner teeth (9) connected to external teeth of a rotor (5) arranged at a rotor chamber (46). Discs (12,13) are arranged at sides of rotor and rotor ring, to axially limit the rotor space. Hydraulic fluid chambers rotatably arranged between teeth, are connected to fluid supply and discharge conduits (33,38). The rolling bearing space is fluid-tightly sealed with the rotor space.
