Abstract (en)
[origin: EP2354551A2] The machine (1) has a housing (2) in which two helical gear wheels (10, 12) and axial bearing bodies (26, 28) are accommodated. Shafts (8, 16) are accommodated in the bearing bodies, where axial force components of force, resulting from hydraulic and mechanical forces during operation of the machine, act on the gear wheels. Compensation bodies (60, 62) are arranged coaxial to the shafts for pressing the shafts with axial compensation forces (50, 51). The compensation bodies and the respective shafts are connected with each other in a torque-proof manner.
