Definitions

  • the first carrier element comprises an annular disk with a hub for attachment to the drive shaft, a collar extending axially in the direction of the containment shell being provided on the annular disk.
  • thermoelectric element is designed essentially as a plate in the shape of a circular disk.
  • the hydraulic housing 3 has an inlet opening 8 for sucking in a pumped medium and an outlet opening 9 for ejecting the pumped medium.
  • the housing cover 4 is arranged on the side of the hydraulic housing 3 opposite the inlet opening 8 .
  • the bearing bracket lantern 5 is attached to the side of the housing cover 4 facing away from the hydraulic housing 3 .
  • the bearing carrier 6 is attached to the side of the bearing carrier lantern 5 opposite the housing cover 4 .
  • the bearing cover 7 is in turn fastened to the side of the bearing carrier 6 facing away from the bearing carrier lantern 5 .
  • An impeller shaft 13 rotatable about an axis of rotation A extends from a flow chamber 14 delimited by means of the hydraulic housing 3 and the housing cover 4 through an opening 15 provided in the housing cover 4 into the chamber 12.
  • An impeller 16 is fastened to a shaft end of the impeller shaft 13 which is within the flow chamber 14, and an impeller 16 is fixed to the opposite end of the shaft the chamber 12 arranged inner rotor 17 is arranged.
  • the inner rotor 17 is equipped with a plurality of magnets 18 which are arranged on the side of the inner rotor 17 facing the can 10 .
  • the second support element 32 is pushed over the collar 28, ie the area 29 of the first support element 25 with a reduced outer diameter, with the step 31 forming a stop device.
  • First and second carrier element 25, 32 are shown as two parts that can be connected to one another by means of a screw connection. Alternatively, the two parts can be joined together using shrink technology. In a further exemplary variant, the first carrier element 25 and the hollow-cylindrical part of the second carrier element 32 can be formed in one piece.
  • the first carrier element 25 has a heat blocking device 34 .
  • the thermal lockout device 34 is positioned within the collar 28 .
  • the heat blocking device 34 comprises a heat insulating element 35 and a heat reflecting element 36.
  • the heat insulating element 35 is designed essentially as a circular-cylindrical body and is made of a very poorly heat-conducting material, e.g. B. mica produced.
  • the heat reflecting member 36 is formed substantially as a disc-shaped plate and is made of a material having a high degree of heat reflection, e.g. B. a stainless steel alloy manufactured.
  • the length of the shank 44 is slightly smaller than the total thickness of the heat reflecting member 36 and the heat insulating member 35 when they are not yet installed. In this way, the heat reflection element 36 and the heat insulating element 35 can be fixed firmly to the annular disk 26 of the first carrier element 25 under a defined prestress.
  • the annular disc 26 of the outer rotor 24 at least one through hole 47, which is in overlap with the through hole 38 in the heat insulating element 35.
  • a on The threaded bolt-like fastening means 48 formed on the heat reflection element 36 extends through the through hole 38 and through the through hole 47 of the ring disk 26.
  • the fastening means 48 has a region 49 with a thread 50 at its free end.
  • the heat blocking device 34 can be fastened to the first carrier element 25 by means of a screw nut 51 which can be screwed onto the fastening means 48 .
  • Two or more through bores 38 are preferably provided in the heat insulating element 35 and in the annular disk 26 and a corresponding number of fastening means 48 are provided.
  • the drive shaft 20 is connected via a coupling device to the output shaft of a motor, not shown, in particular an electric motor.
  • a coupling device to the output shaft of a motor, not shown, in particular an electric motor.
  • the invention can also be used, for example, in a pump arrangement designed in the so-called block design, in which the first carrier element is fastened directly to the output shaft of the motor.
