Abstract
Gear pump with intermeshing gearwheels enclosed by a housing with bearing journals on shaft axes projecting laterally from the gear wheels mounted in the housing by slide bearings each having a slide bearing length, each having a lubrication pocket with radial expansion. The lubrication pocket is spaced from a gear-side end face of the respective slide bearing by a first distance, having a first bar with a first bar width with axial expansion corresponding to a slide bearing surface. The lubrication pocket is spaced apart by a second distance from the bearing end face opposite the gear end face. A second bar with a second bar width with axial extension corresponds to a slide bearing surface, a bore leads through the slide bearing and communicates with the lubrication pocket at an injection point. The bore is operatively connected to a conveying device for conveying lubricating medium into the lubrication pocket.
