Definitions

  • the invention relates to a motor pump unit comprising an electric motor and a pump.
  • the motor and pump are nested; the engine envelops the pump.
  • EP 0 611 887 A1 describes another motor pump unit.
  • the rotor of the engine is an independent component, but rotatably connected to the cylinder block of a piston pump.
  • the invention has for its object to further improve a motor pump unit of the type mentioned, in particular with respect to the manufacturing costs and space requirements.
  • the entire motor pump unit comprises two axially aligned internal gear pumps and an electric motor which is associated with the one of the two pump.
  • the adjacent pumps are assigned to each other such that they can be driven by a single electric motor. It can thus achieve a high delivery volume and / or a high delivery pressure.
  • a big advantage is that the two pumps are inside a single housing are arranged so that they are enclosed in the operation of the entire unit of oil and therefore no seals are needed.
  • the two pumps can be completely identical. But they can also have different diameters in the conveying area, i. where the conveyor tooth boundary is located.
  • the invention can be applied to internal gear pumps.
  • the pump forms a completely independent, self-sufficient unit. It can be manufactured separately, tested separately and installed completely in the space enclosed by the stator of the electric motor.
  • the engine is cooled with oil.
  • the motor pump unit comprises an electric motor 1 with a laminated stator core 1.1, a winding 1.2 and a rotor 1.3.
  • first internal gear pump 2 This has a pinion 2.1, a relative to this eccentric ring gear 2.2 and a pinion shaft 2.3.
  • the pinion shaft 2.3 is mounted in side windows 2.4, 2.5.
  • plain bearings 2.4.1, 2.5.1 are provided.
  • the two elements motor and first pump are enclosed by a common housing 3.
  • a common housing 3 In the housing 3 there is an inlet 3.1 and a first outlet 3.2 for the medium to be pumped.
  • the rotor 1.3 of the engine 1 is cup-shaped. In the present axial section, it appears U-shaped.
  • the pinion shaft is 2.3 with the rotor 1.3 via a tooth 2.3.1 in rotary connection.
  • the web 1.3.1 of the U namely an internal toothing
  • the pinion shaft has a corresponding external toothing. Internal teeth and external teeth mesh with each other.
  • the rotor 1.3 is mounted on the first pump 2, more precisely on the ring gear 2.3 and the side windows 2.4, 2.5.
  • a second internal gear pump is provided. This is arranged axially adjacent to the first pump 2, in such a way that the axes of the two pumps are aligned.
  • the housing 3 is led out beyond the first pump 2 and also flows around the second pump 20.
  • the second pump 20 is identical in construction to the first pump 2. It accordingly has a pinion shaft 20.3, which with the pinion shaft 2.3 is identical and which is also about a toothing 20.3.1 with the rotor 1.3 in rotary connection.
  • the housing 3 has a second outlet 3.3.
  • the second pump 20 is fixed to the right lid of the housing 3.
  • the pot-shaped rotor 1.3 drives the two pinion shafts 2.3, 20.3.
  • the course of the oil is shown by the bold arrows.
  • the oil is sucked in at inlet 3.1, shown in the figure on the left, passes through the gap between stator lamination 1.1 and rotor 1.3 in the space between the two pumps 2 and 20. There, the oil flow is divided. A partial flow passes through the pump 2 and at the first outlet 3.2 again, and a second partial flow passes through the second pump 20 and the second outlet 3.2 from.
  • the motor pump unit thus has a suction port and two pressure ports.
