Definitions

  • the invention relates to a hydraulic combination unit, with a rotating driven pump and one with its drive axis coaxial to the axis of rotation of the Pump arranged and thus rotatably connected drive motor.
  • the Combination unit includes, for example, in addition to the pump and its Drive motor often also the tank as well as various controls, valves and the like, the mutual arrangement of the individual elements for Taking into account the respective requirements can be very different.
  • different capacities and for the various purposes so that sizes of the individual elements are required there is a total of one large number of manufacturers of such units in stock or on request elements to be kept ready, for example only a number of different ones Drive motors together with otherwise essentially the same To be able to use components.
  • the object of the present invention is to overcome the disadvantages mentioned to avoid known arrangements of the type mentioned and in particular to design such a hydraulic combination unit so that combinations different parts as simple as possible and with little additional effort can be realized.
  • the centering between The output axis of the drive motor and the axis of rotation of the pump are advantageously implemented Way directly between the sealing flange and centered on the pump housing the housing of the drive motor, so that the attachment of the drive motor on Carrier flange and its independent attachment to the sealing flange on it cannot have a negative impact.
  • the Carrier flange at least two independent fasteners, preferably with Through holes interacting with screws, for the sealing flange on the one hand and the drive motor on the other hand and that concentric with the axis of rotation of Pump and drive motor separate centering elements on the carrier flange on the one hand and on the sealing flange and drive motor on the other hand compared to the direct Centering between drive motor and sealing flange having greater play Assembly pre-centering are provided.
  • this one to the output axis Has concentrically protruding centering that in a to the axis of rotation Pump concentric recess on the sealing flange that the Recess on the sealing flange in turn in a protruding centering approach is formed, which has a concentrically arranged precentering surface on the outside precentering interaction with a precentering surface on the Has through bore of the support flange, and that the centering of the Sealing flange is recessed like a groove at at least two spaced locations, wherein in these grooves from the precentering surface of the carrier flange for the Sealing flange starting with inward centering approaches for the Engage the pre-centering of the carrier flange on the centering shoulder of the drive motor.
  • a shaft seal can be arranged, which in the axial Direction on the one hand from a gradation of the through hole and on the other hand from Centering approach of the inserted drive motor is held and thus on very simple way the pump side is reliable in relation to the drive and the environment seals.
  • the Flange unit preferably the support flange alone, for fastening Additional elements, such as an engine cover or electrical or electronic peripheral elements, with extensions, fasteners and provided the same, which is also very simple and for many variants a wide variety of designs requiring as few different parts as possible or allows the consideration of various requirements.
  • Fig. 1 shows one Combination unit according to the invention in a section along the line A-A in FIG. 2
  • 2 shows the combination unit according to FIG. 1 in side view
  • FIG. 3 shows one Section along the line B-B in Fig.1.
  • the combination unit shown consists essentially of a rotating driven pump 1 and one with its output axis 2 coaxial to the axis of rotation 3 the pump 1 arranged and thus rotatably connected drive motor 4th
  • the pump housing 5 which, for example, also not shown here Way the tank of the unit or control or regulating valves or the like may contain - and drive motor 4 is one of the output axis 2 of the Drive motor 4 sealed through flange unit 6 arranged, which one the pump housing 5 sealing and against this and the axis of rotation 3 of the Pump 1 centered sealing flange 7 and one hand on the sealing flange 7 and on the other hand, has a carrier flange 8 detachably fastened to the drive motor 4.
  • the carrier flange 8 has two independent screws according to Figure 3 interacting through holes 9, 10 for attachment to the sealing flange 7 on the one hand and on the drive motor 4 on the other.
  • Concentric to the axis of rotation of Pump 1 and drive motor 4 are separate centering elements 11, 12 on the carrier flange 8 arranged on the one hand and on the sealing flange 7 and drive motor 4 on the other.
  • Sealing flange 7 is thus a larger game pre-centering assembly between the carrier flange 8 and the drive motor 4 on the one hand and between given the carrier flange 8 and the sealing flange 7 on the other hand.
  • this has one Drive axis 2 concentrically protruding centering projection 13 on which in a Rotation axis 3 of the pump 1 concentric recess 14 on the sealing flange 7 is insertable.
  • This recess 14 on the sealing flange 7 is in turn in one protruding centering projection 15 formed, which is concentric on the outside arranged pre-centering surface 16 (see Figure 3) for pre-centering interaction with a pre-centering surface 17 on the through bore of the carrier flange 8 has.
  • the centering projection 15 of the sealing flange 7 is (as also from FIG.
  • a shaft seal 21 which in the axial direction on the one hand from a step 22 of the through hole 20 and on the other hand from the centering projection 13 of the inserted drive motor 4 is held.
  • the flange unit 6 and in particular the support flange 8 for attaching additional elements such as Example of an engine cover 23 or of electrical or electronic peripheral elements 24 may be formed, for which purpose a bent extension 25 on Carrier flange 8 is provided, which corresponding mounting holes or the like can wear.
