Definitions

  • the present invention relates to a gear pump for pumping liquids.
  • the present invention relates to an electrically operated gear pump which can advantageously be used to feed fuel to an internal combustion engine. This is a use to which the text which follows will make explicit reference, without thereby losing generality.
  • a number of models of electrically operated gear pumps for liquids comprise: an annular stator unit capable of generating a rotating magnetic field; a ring gear with inner toothing, which is inserted/fitted in an axially rotatable manner on the inside of the stator unit; and finally a gear wheel, which is fitted in an axially rotatable manner on a support pin positioned eccentrically on the inside of the ring gear and meshes on the inner toothing of the ring gear.
  • the rotation of the ring gear on the inside of the stator unit creates a movable volume that is capable of transferring a predetermined quantity of fuel or other liquid from the intake port of the pump to the delivery port of said pump.
  • the flow of the liquid exiting the pump obviously depends on the speed of rotation of the ring gear.
  • the gear pump is finally also equipped with a tubular bush, which is interposed between the outer surface of the ring gear and the inner surface of the stator unit in such a way as to reduce the wear of the two components and at the same time facilitate the insertion of the two gears into the stator unit.
  • the tubular bush is generally fixed immovably on the inside of the stator unit by means of the adhesive which is injected into the interstitial space between the bush and the stator unit.
  • the mechanical play present between the bush and the stator unit is reduced to such an extent as to make it extremely difficult for the adhesive to penetrate between the two components, and therefore the adhesive is injected into the interstitial space between the bush and the stator unit by means of particularly complicated and expensive machinery.
  • the present invention also provides a method for assembling a gear pump.
  • FIG. 1 is a sectional view of a gear pump formed according to the requirements of the present invention.
  • FIG. 2 is a partially exploded perspective view of the gear pump shown in FIG. 1 , with parts removed for clarity.

  • a substantially cylindrical outer tubular jacket 10 which is preferably made of a metallic material and extends coaxially with the longitudinal axis A in such a way as to surround the polar cores 8 of the stator unit 2 and the bush 4 .
  • each polar core 8 further forms a link and/or extends in a cantilevered manner from the tubular jacket 10 towards the bush 4 positioned in the centre of said tubular jacket 10 .
  • the tubular jacket 10 is also preferably formed by a stack of laminations, which are placed closely next to one another and are preferably made of a ferromagnetic material, and the polar cores 8 are preferably formed in one piece with the tubular jacket 10 .
  • the metallic laminations which form the outer tubular jacket 10 are cut in such a way as to also form the polar cores 8 .
