Definitions

  • the e invention relates to a gear pump in which the one circumferential pump wheel is mounted axially displaceably in the pump housing and engages at least on one end wall of this pump wheel an axially displaceable sliding part which is able to cover the working space filled by the pump wheel with respect to the other, axially fixed pump wheel, whereby the sliding part on its, the other, fixedly mounted pump wheel facing part of its outer surface has an outline shape that is the same as the path tooth tips of this pump wheel.
  • gear pump is known for example from DEPS 375 986.
  • this construction has not found practical application in the past 60 years.
  • gear pumps, the z.3. effect the supply of lubricating oil to a motor vehicle or a machine tool, controlled or regulated as required with regard to their flow rate or pressure.
  • gear pumps have only been influenced in their delivery rate by means of a speed control, which is associated with relatively great effort.
  • the gear pump for the lubricating oil supply is permanently set to the maximum required delivery rate and operated constantly. Since a significantly lower delivery rate is required at high engine speeds than at low speeds, pressure relief valves are provided in the delivery lines, which reduce the excessive pump pressure. However, this means that the gear pump due to its rigid maximum design during an essential Part of their operating life is a power consumer, and is therefore uneconomical.
  • the pump housing on the, the pressure side of the pump between the pump impellers diametrically opposite through the axially displaceable impeller has a pocket-like recess which is hydraulically connected to the pressure side of the pump and that this recess on one Place of the pump housing is arranged., Which is also in the effective range of the pump wheels when the pump wheel is axially displaced.
  • An alternative or supplementary additional hydraulic relief of transverse forces is according to a value development of the invention is that in the sliding part axially on both sides of the pump wheel actuated by him and diametrically opposite that between the pump wheels Pocket-side recesses are provided on the pressure side of the pump, which are hydraulically connected to the pressure side of the pump between the pump wheels.
  • the impeller 2 is seated on a driven shaft 4.
  • the impeller 3 is loosely rotatable on a journal 5 of a sliding part 6 arranged in the pump housing 1 and guided in an axially displaceable manner the end of the pump wheels facing away from the sliding part 6 is limited and serves as a guide means.
  • 3 and 4 show an embodiment of this gear pump as a regulated pump.
  • Ver Sliding space 8 of the pump housing 1 is arranged as a control spring 9, preferably a prestressable compression spring, which is supported on the end face on a preferably axially adjustable base plate 10 on the one hand and on the end face 11 of the sliding part 6 on the other hand.
  • the other side 12 of the pump housing 1 is connected to the pressure side 13 (FIG. 7) of the gear pump, specifically at a point 14 where the two pump wheels 2, 3 are still at maximum mutual axial displacement overlap, ie where they are still effective as a pump.
  • a further possibility of hydraulic relief is shown. This consists in that, instead of in the sliding part 6 in the pump housing 1 itself, a pocket-like recess 19 is provided, which is hydraulically connected to the pressure side 13 of the pump via suitable bores 20.
  • FIGS. 7 and 8 show a further embodiment of a gear pump with its maximum or minimum delivery position.
  • the displacement space 8 and the side 12 of the pump housing 1 are each connected to a controller 22 which determines the axial position of the sliding part 6 as a function of a parameter.
  • the housing section 26 adjoining the housing section 25 is likewise slightly offset eccentrically with respect to the housing section 24. Its inside diameter corresponds to the tooth tip diameter of the pump wheel 34.
  • the pump delivery rate of the maximum setting shown in FIG. 12 is changed by axially displacing the pump wheel 34 and the sliding part 28 into a minimum position which corresponds to the axial length of the tooth engagement.
  • FIGS. 11-13 show an embodiment of a pump with a ring gear similar to FIGS. 11-13, but with the difference that here the ring gear 37 is relative. is axially displaced to the pump housing 23 and the driving pump wheel 34 rotates axially stationary in the pump housing 23.
  • This embodiment largely corresponds to that of FIGS. 14-16, but has some differences from it.
  • the pump housing 45 consists of a central cylindrical section 47 and two annular sections 46 and 48 adjoining it on both sides.
  • a sliding part 52 is arranged, which extends into section 48 and has an eccentric cylindrical recess 53.
  • the axially displaceable second pump wheel which is designed as an internally toothed ring gear 54, is rotatably and positively held in this recess 53.
  • a helical spring 55 located in the housing section 48 acts as a return or control spring.
  • the annular sliding part 52 sits centrally in the housing section 46 and has an eccentric bore 56.
  • the cylindrical pump housing 57 has a central recess 58 for receiving an internally toothed Eaton ring gear 59, the toothing of which is in meshing engagement with a pump wheel 60 which is firmly seated on an axially displaceable drive shaft 61 mounted eccentrically in the pump housing 57.
  • One end face of the pump wheel 60 rests on a collar 62 connected to the drive shaft 61, on which a return or control spring 63 arranged in the pump housing 57 engages.
  • the entire length of the impeller 60 meshes with the ring gear 59.
  • a sliding part 64 is mounted on the drive shaft 61 and is axially fixed to the drive shaft 61 by a collar 65 connected to the drive shaft 61. If pressure is exerted on the free end face of the sliding part 64, the drive shaft 61 and, with it, the sliding part 64 and the pump wheel 60 move to the left relative to the ring gear 59 (FIG. 22), so that the delivery rate is reduced.
  • the sliding part 64 is of circular cylindrical design and sits eccentrically on the drive shaft 61.
  • the outer diameter of the sliding part 64 corresponds to the inner diameter of the one outer housing section 66 and the ring gear 59, while the inner diameter of the other outer housing section 67 corresponds to the outer diameter of the pump wheel 60.
