Gear pump with intermeshing gear wheels enclosed by housing with bearing journals arranged on shaft axes and use thereof

Gear pump with intermeshing gear wheels (1) enclosed by a housing with bearing journals (5, 6) arranged on shaft axes (9), each projecting laterally from the gear wheels (1), which are mounted in the housing by means of slide bearings (3), having a slide bearing length (L), the slide bearings (3) being lubricated with pumped medium, characterized in that:

• a filling pocket (2) with radial expansion is incorporated in each of the slide bearings (3) in a region of a pump pressure side, the filling pocket (2) being spaced apart from a gear-side end face (7) of the respective slide bearing (3) by a distance (d), so that a bar (11) with a bar width (D) with axial expansion corresponding to a slide bearing surface is formed;
• and
• a lubricating groove (4) with a tampering cross-section is provided in each of the slide bearings (3), the lubricating groove (4) starting from an end on a gearwheel side towards a slide bearing end and starting at the filling pocket (2) on the gearwheel side and communicating therewith.
