| 摘要 |
The invention relates to an internal gear pump (1). For hydrodynamic lubrication, the invention proposes wedge gaps (24) between axial discs (16) and a ring gear (2) and a pinion of the internal gear pump and/or bores (25) through the axial discs (16), said bores communicating with a suction region (8) of the internal gear pump (1) and, when the ring gear (2) and the pinion are driven in rotation, form a lubricating film between the axial discs (16) and the ring gear (2) and the pinion in a comparable manner to hydrodynamic lubrication of an axial plain bearing. |
