Definitions

  • the invention relates to a pump, in particular vane pump or roller-cell pump, wherein the wing or roller-cell pump has a zwehübigen contour ring and a rotor, are stored in the radially displaceable wings or rollers, with at least one, optionally two side plates which laterally seal the rotation group, with a housing and a housing cover, wherein the rotor is driven by a shaft and the shaft is mounted in the housing and optionally in the lid.
  • the invention relates to a double-vane vane pump, this double-flow vane pump by dividing into two pump halves at high speeds turn off a pump half demand and the funded amount of this pump half can be returned to the intake.
  • This shutdown is that the rotor and the stroke ring of the pump in the radial direction are no longer pressure balanced, since in the switched-off pump half almost no pressure is built up.
  • lifting rings mounted on pins are pushed radially more strongly out of their original position due to the bending of the pins as the operating pressures increase.
  • the mounted on the shaft rotor is moved because of the shaft deflection in the opposite direction from its original position.
  • a pump in particular a vane pump or roller-cell pump, having the features of claim 1.
  • a second side plate is positioned by a third pin to the housing or the lid to each other, wherein the third pin does not penetrate the second side plate and also has no contact with the contour ring.
  • the third pin in the same passage opening, but arranged in different components.
  • a pump in which the first and second, optionally the third pin each protrude into the middle of the respective side panel thickness. Furthermore, a pump is preferred in which the first and the second, if appropriate, the third pin are arranged in a so-called “genoa hole”, that is to say that they constitute a so-called “gene connector connection” in a round hole.
  • a further pump according to the invention is characterized in that a fourth and a fifth pin are arranged in a so-called “elongated hole", wherein slots are formed in the plates and in the cover or possibly in the housing and in the cam ring holes, and that the fourth pin in principle, as the first pin and the fifth pin are in principle designed and arranged like the second pin.
  • Another pump according to the invention is characterized in that the second, third and fifth pin have a different diameter than the first and the fourth pin and therefore, the holes in the side plates are made discontinued. Furthermore, a pump is preferred in which the housing is cup-shaped. Also, a pump is preferred in which the rotation group is fixed to the cover. A pump according to the invention is characterized in that the shaft is additionally mounted in the lid.
  • FIG. 1 shows a rotation group of a vane cell pump with only one pressurized region under transverse force.
  • a rotor 3 which contains radially movable vanes 5 in slots and is rotationally driven by a shaft 7. Between the wings 5, the contour ring 1 and the rotor 3 form vane, which increase or decrease accordingly upon rotation.
  • the wing cell 9 z. B. is a tikfördemde cell, which, seen in the direction of rotation 17, reduced by the "case” 18 and thus promotes pressurized fluid.
  • the pressure range of the vane pump is additionally represented in this position by the pressure range 9.1 and 9.2. So it includes three cells in this position.
  • the lower pressure kidney 11 of the vane pump should be switched in this case to non-pressurized circulation, so that no pressure builds up here.
  • the pressure build-up in the upper pressure region 9 causes a reaction force 19 on the contoured ring 1 to shift the contoured ring 1 upwards, while on the other hand a compressive force component 21 on the rotor 3 wants to displace it downwards and thus to an inadmissibly large deflection of the shaft 7 can lead if it does not have a corresponding high strength.
  • the contour ring 1 and not shown here Side plates contain through holes 23 and 25, with which they are connected by means of pins with each other and with a housing, not shown here, in which the shaft 7 is mounted, so that closes here the circle of forces.
  • a vane pump is shown in cross section.
  • the shaft 7 is mounted by means of a bearing 29 and sealed by a seal 37.
  • the housing is closed by a housing cover 31, in which the shaft 7 is mounted in a second bearing 33.
  • the contour ring 1, the rotor 3 with wings not shown here and the side plates 39 and 41 form the rotation group.
  • the rotor 3 is axially fixed by a locking ring 35 on the shaft.
  • the cam ring 1 is connected to the side plates 39 and 41 above a first pin 43.1 and below via a fourth pin 43.4.
  • the side plate 39 is further connected to the housing 27 with a short third pin 43.3.
  • the side plate 41 is connected via a short second pin 43.2 and a short fifth pin 43.5 with the housing cover 31.
  • Figures 3.1 and 3.2 the displacement of the three-piece Weglink system is shown due to the games
  • Figure 3.2 is a variant with remote pins according to claim 11. It can be seen that the contour ring 1 is displaced upward relative to the central pin 43.1 and rests against the pin 43.1 from below.
  • the Game of the gene hole connection is represented by the upper gap 45.
  • the pin 43.1 again engages in the side plates 39 and 41 at the top, so that in each case a lower gap 46 and 47 is formed here.
  • the plate 39 in turn lays against the underside of the pin 43.3, which in turn comes to rest on the upper side in the housing 27 and thus forms a lower gap 48.
  • an internal gear pump of the orbit pump type is shown by way of example in FIG.
  • an internally toothed ring gear 50 which also represents the outer contour of the pump part
  • a gear 51 is arranged.
  • an eccentric 52 is rotatably mounted, which can rotate with respect to the gear 51 slidably and during this rotational movement, the gear 51 successively pushes into the tooth spaces of the external gear 50.
  • the eccentric 52 is arranged on an eccentric shaft 53.
  • the Pumpenkammem which just perform compression work while building pressure, are marked with hatched areas 54.
  • the individual Wegstatte are arranged as follows in the pump.
  • a Wegstatt 43.3 is fixed in the pump housing 27 in a hole (round hole) and positioned the side plate 39 in the rotational group space of the pump housing. This Wegstatt 43.3 extends halfway into the round hole in the side plate 39.
  • Another Wegstatt 43.1 inserted continuously in the cam ring 1 also in a round hole and projects in each case half in the side plate 39 and in the side plate 41 in a round hole connection.
  • Another Wegstatt 43.2 extends halfway into the side plate 41 and is fixed in the lid 31 in a round hole.
  • a “slot pin” 43.5 is fixed in the lid 31 in a round hole and extends halfway into the slot in the side plate 41.
  • Another “slot pin” 43.4 inserted continuously in the cam ring 1 in a round hole and protrudes halfway into the slot in the side plate 41 and half in the slot in the side plate 39th
  • the two pins 43.2 and 43.5 which are mounted in the lid 31, and the pin 43.3, which sits in the housing 27, should be made with the same diameter and the same length.
  • the two pins 43.1 and 43.4, which sit in the lifting ring, should also have the same diameter and have the same length.
  • the holes of the second side plate 41 and the first side plate 39 can be carried out in accordance with Figure 3.2 approximately in the center of the plate and the diameters are different according to the different pin diameters. Since with appropriate pin arrangement, the "slot pins" 43.4, 43.5 only need to absorb the torque and thus only small forces occur, you can also omit the division of the pins here.
