  • Patent number: 7495575
    Abstract: A gear pump for the dosed conveyance of pigmented lacquers or paints and which is adapted for use with a painting robot. The gear pump comprises two toothed wheels meshing with one another and which are mounted within a pump housing in such a manner that they can be rotated by a driven drive shaft and a fixed bearing shaft. For this, the drive shaft is mounted by a bearing section at multiple points in a pump housing and a coupling section of the drive shaft projects out of the pump drive to connect to a drive. In order, on the one hand, to avoid wear due to high pressure forces and, on the other hand, to absorb a pronounced load from the outside, a supporting bearing for the radial and axial support of the drive shaft is formed on the drive shaft's coupling section projecting outside of the pump housing.
