Definitions

  • the present invention relates to a device according to the preamble of claim 1 and a use the device.
  • Magnetic clutches are used for torque transmission between not touching waves, i.e. one to be sealed Rotary union, as for example for the from the Housing out with a gear pump Drive shaft is necessary with a gear pump with magnetic coupling not required.
  • Using magnetic couplings driven pumps only have statically acting Seals on, which is why they are hermetically sealed apply and therefore especially for extreme environmentally hazardous or toxic fluids are suitable.
  • Known magnetic couplings consist of a bell-like External rotor, the single- or double-walled containment shell and the Inner rotor.
  • the outer rotor usually sits on one Motor shaft or a transmission output shaft and the Inner rotor is located on the out of the pump housing led out drive shaft of the gear pump.
  • the Torque is transmitted by magnets, which are on the inner surface of the outer rotor and on the Outer surface of the inner rotor.
  • Magnetic clutches this known type are because of the mentioned Application benefits more and more often and preferably also used for ever larger services to be transferred.
  • the present invention is therefore based on the object based on a device with a magnetic coupling indicate which of the above disadvantages do not having.
  • the invention has the following advantages: By the shaft driven by the drive unit with the drive-side rotor is articulated and by the Axis of the drive-side rotor via fixing elements, which are preferably designed as roller bearings, radially is fixed, the axes of the driven shaft and that of the drive-side rotor does not coincide. Rather, these may be misaligned, without the function of the overall system being impaired.
  • Another embodiment variant of the invention in which the storage locations, i.e. the rolling bearings, radial to the containment shell the magnetic clutch are arranged, also points the advantage that when assembling the magnetic coupling whose outer rotor, guided by the fixing elements, over the can can be pushed without a Misjudgment is possible.
  • This embodiment of the invention also has the advantage that the outer rotor bearing closer to the containment shell and thus to the place where a precise positioning, especially in the radial direction, is crucial.
  • gear pump 1 shows a gear pump 1, a magnetic coupling 2 and a universal joint 14 is shown, wherein to drive the Gear pump 1 is a drive unit (not in Fig. 1 shown) is connected to the universal joint 14.
  • the gear pump 1 consists essentially of a Pump housing 21, consisting of two intermeshing gears 3 and shaft bearing 6, in which the gears 3 supporting Shafts 4 are stored.
  • One of the waves 4 is from the Pump housing 21 led out for driving the pump.
  • An outer rotor 12, which also on its inner surface is equipped with magnets 19, is radial to the inner rotor 17 arranged, between the inner and the outer
  • a so-called containment shell 16 is provided for the rotor 17 or 12 that enables a complete seal.
  • On the drive side i.e.
  • the shaft section 11 is further over a Universal joint 14 with a drive shaft 13, i.e. preferably first with an inner part of a Drive shaft, which inner part over a second Universal joint (not shown in Fig. 1) with the actual drive shaft of a drive unit (in FIG. 1 not shown) connected.
  • the magnetic coupling 2 thus forms with respect to the radial one Mobility one unit with the gear pump 1 or with whose housing 21, which advantageously achieved is that the drive shaft 7 of the gear pump 1 with the Drive axis 13 of the drive unit is not exact must coincide.
  • At least one of the drive shaft sections i.e. the Drive shaft section in front of the first universal joint 14 and / or between the two universal joints and / or after the second universal joint, is telescopic and can be extended or shortened as required.
  • the fixing element 8 is detachable Fasteners 15, preferably made of screws exist, attached to the pump housing 21.
  • the fixing element 8 tubular and closes the magnetic coupling 2 to the outside from, ventilation holes 9 are provided.
  • roller bearings 10 being radial to the containment shell 16 are arranged. This is the storage of the outer rotor 12 closer to the containment shell 16 and thus to the Place where precise positioning is critical is.
  • Fig. 2 shows essentially the magnetic coupling 2. From the Gear pump 1 are only individual parts, namely that Pump housing 21 and cutouts of the shaft bushing Drive shaft 7 shown.
  • roller bearings 10 In addition to the mentioned advantage regarding an ideal Force absorption in radially arranged roller bearings 10 has the further embodiment also has the advantage that assembly can be carried out in a simple manner. So the outer rotor 12 becomes simple at the end of the assembly pushed onto the can 16 without touching it is because the roller bearings 10 ensure that the magnets 19 of the outer rotor 12 and the containment shell 16 continuously are spaced.
  • FIG. 3 in a schematic representation, three shaft sections 31, 32 and 33 of the drive shaft shown, the first shaft portion 31 with the second shaft section 32 via a first flexible Coupling 34 and the second shaft section 32 with the third shaft section 33 via a second flexible Coupling 35 are connected.
  • the shaft section 33 corresponds to the rigid, out of a drive unit 30 guided drive shaft.
  • the outer rotor 12 FIGGS. 1 and 2) of the magnetic coupling 2 (FIG. 1 and 2) connected to the first shaft section 31.
  • the Flexible couplings 34 and 35 are in one of those discussed Form realized.
  • the second is Shaft section 32 formed telescopically.
