Definitions

  • the invention relates to a pump for conveying a fluid, with a in a housing housed conveyor, with the housing on one side is closed by a housing cover and there is a bearing flange on the other side connects, with a drive shaft the bearing flange, the conveyor and penetrates the housing cover and in a formed in the bearing flange Passage is stored and being between the conveyor and the Inner wall of the bearing flange is supported on the inner wall, the Drive device in the housing centering side plate is arranged.
  • Pumps of the generic type are used, for example, in power steering systems and promote a special oil to support the steering wheel of a Motor vehicle to be applied steering force. It is preferably These are vane pumps that are provided outside of the pump Draw in the reservoir, for example from an external tank, oil.
  • Such Pumps are usually equipped with a flow control valve through which oil is released the high pressure area - pressure side - in the suction area - suction side - the Pump can be directed. From a certain pump speed and at a flow rate, the flow control valve opens an outflow hole, through which oil under high pressure can escape. The oil gets into the Suction area of the conveyor.
  • a generic pump is known per se, where the drive shaft penetrates the bearing flange and there from suitable Storage is held.
  • On the inside of the housing arranged end of the Drive shaft is rotatably mounted in a pressure plate carrier.
  • the printing plate carrier is by a suitable compression spring, which is on the one hand in the pressure plate carrier and, on the other hand, supported on the housing, pressed against a pressure plate, which in turn rests against a rotor that accommodates several blades.
  • the Wings are radially slidably mounted in corresponding slots in the rotor are incorporated.
  • Rotor - On the side facing the bearing flange of the non-rotatably connected to the drive shaft Conveyor device - in this case it is a Rotor - is the side plate that is on its side facing away from the rotor Bearing flange supported.
  • the side plate - For centering the side plate and thus the conveyor or the rotor is the side plate - in a conventional manner - with special Centering means provided, specifically as centering pins on the bearing flange facing side of the side plate are formed and in corresponding holes protrude into the bearing flange.
  • the present invention is therefore based on the object of a pump of the generic type Kind to design and develop in such a way that a simple Centering of the side plate or side plates while reducing reference tolerances to the shaft center or middle of the bearing is possible.
  • the pump according to the invention achieves the above object through the features of claim 1.
  • a pump of the generic type characterized in that the side plate on the side facing the bearing flange is centered directly in the passage for the drive shaft.
  • the conventional Centering of the side plate has to go off using centering pins, in order to avoid reference tolerances effectively reduce to the center of the shaft or the center of the bearing can.
  • the passage in the bearing flange should have the Align the passage in the side plate exactly.
  • the generic pump according to DE 41 38 516 A1 the drive shaft through the bearing flange into the conveyor or extends through the conveyor and on the opposite End is stored.
  • the Drive shaft not only through the conveyor, but on the Bearing flange opposite side of the conveyor through the Housing cover extends through.
  • the housing cover is similar as in the bearing flange - a passage or a hole is formed through which the drive shaft protrudes through.
  • the drive shaft is under one such design not only in the passage of the bearing flange, but also in Passage of the housing cover mounted, being between the conveyor and the inner wall of the bearing flange and also the housing cover one each is arranged on the inner wall supporting side plate, so that the drive device on both sides of a side plate - in the printed version of the Technology often called pressure plate - limited and therefore centered.
  • the side plate not only on the side facing the bearing flange, but also on the side facing the housing cover directly in the Passage for the drive shaft is centered, namely when the drive shaft completely through the housing and thus also through the housing cover extends.
  • this on the side facing the passage is at least largely circumferential Centering collar and inserted with the centering collar in the passage is.
  • the centering collar limits the passage in the side plate, so that with inserting the centering collar into the passage of the bearing flange and if necessary of the housing cover automatically centering or positioning the side plate is reached.
  • the centering collar could be partially or zonally or circumferentially his.
  • the side plate comprises an anti-rotation device.
  • the centering collar itself, namely if this in is designed to prevent rotation.
  • the Centering collar could itself serve as a rotation lock, namely if Passage - for inserting the centering collar - with appropriate measures is equipped to stop the partially formed centering collar.
  • the anti-rotation device on the side facing the passage Side of the side plate comprises special engagement means, said engagement means can also be formed directly in the region of the centering collar. there it can, for example, be a matter of engagement noses which fit into corresponding recesses in the inner wall of the bearing flange or the housing cover and / or the Grasp passage.
  • Fig. 1 shows a simplified representation of a generic pump in one sectional side view, here specifically a vane pump with a rotation group 1 or conveyor not described here is.
  • a rotating group 1 is only referred to DE 41 38 516 A1 as an example.
  • the pump shown here comprises - as essential components - a housing 2 and a conveying device accommodated in the housing 2, whereby it is is the rotation group 1 already mentioned.
  • the front is on one side a housing cover 3 that closes the housing 2 and on the other side - on the side opposite the housing cover 3 - one on the housing 2 subsequent bearing flange 4 is provided.
  • the seal acting against the housing cover 3 5 is inserted in a groove 8 formed in the end face 7 of the housing 2.
  • the seal 6 is assigned to the bearing flange 4 or inserted into a groove 9 machined into the bearing flange 4.
  • the groove 9 could also be incorporated into the end face 10 of the housing 2.
  • a drive shaft 11 penetrates the bearing flange 4, the conveyor 1 and the housing cover 3.
  • the housing cover 3 represents the bore or the passage 15 itself the storage Radial roller sealing rings 13 are provided on the inside.
  • the bearing is formed in the passage 14 of the bearing flange 4. Also radial roller sealing rings 12 are connected inwards here.
  • the Conveyor 1 arranged in the housing 2 centering side plate 16, 17.
  • the Side plates 16, 17 serve, among other things. to center the conveyor 1, especially but also for the separation between suction and pressure side.
  • the side plate 16 is on the side facing the passage 14 equipped with a circumferential centering collar 18, the side plate 16 with the centering collar 18 in the bearing flange 4 or in the passage 14 there the radial roller sealing ring 12 is inserted.
  • the side plate 16 further includes torque support shown in FIGS Figures - because of a clear and simple representation - is not shown. Specifically, these are torque support lugs, that of the side plate 16 are permanently assigned. These torque support lugs engage in corresponding ones Recesses in the inner wall of the bearing flange, so that an unwanted Rotating the side plate 16 is effectively avoided.
