Definitions

  • the invention relates to a turbomachine wheel with a shaft hub, the one Has inner part and an outer part, wing blades from the outer hub part stand away.
  • Such a turbomachine wheel comes at an uncontrolled one medium with hydraulic conditions or properties such as Sewage, faeces, with mud or the like freighted liquids or the like to Application, as a result of the changing consistency etc. Impacts on the fluid machine wheel cannot be avoided. These lead to unwanted vibrations and, in extreme cases, irreversible damage the turbomachine wheel or the associated drive motor, the gearbox, the brackets therefor, etc.
  • an impeller for a vacuum cleaner is known.
  • This known impeller has a shaft hub with a hub inner part and a hub outer part from the hub outer part are blades path.
  • DE-PS 759 535 describes a fan impeller whose blades are under Interposition of disks or the like. made of elastic rubber with a Motor shaft are connected. The blades are separate and separate from each other so attached to the rubber washers that their masses only are connected to each other via the rubber washers, but none among themselves To have touch.
  • This well-known fan impeller probably has a hub inner part on, but an outer hub part is not provided there. Much more there the wing blades are separate components.
  • the invention has for its object a turbomachine to create the type mentioned, in which bumps or blows cushioned and consequently vibrations at least reduced or damage be prevented.
  • a turbomachine wheel a submersible mixer or for a sewage, sludge, dirty water or Sewage pump or for a recirculation pump, with a shaft hub, the has a hub inner part and a hub outer part, from the wing blades stand away, the outer hub part and the inner hub part with each other are entangled and between the inner hub part and the outer hub part a hub damping element made of an elastic material is provided and / or wherein between the outer hub part and the respective wing blade Wing-leaf damping elements are provided from elastic material.
  • a hub damping element or only between the outer hub part and the respective wing blade, wing blade damping elements or both between the inner hub part and the Hub outer part a hub damping element as well between the Hub outer part and the respective wing blade, wing blade damping elements to provide.
  • the respective training is especially of it depending on which media the turbomachine wheel is used reached.
  • both corresponding torque as well as the respective thrust transmitted whereby Impacts or impacts due to uncontrolled hydraulic conditions or Properties of the respective medium through the hub damping element and / or by the blade damping elements in an advantageous manner cushioned and damped.
  • This has the advantage that unwanted vibrations or, in extreme cases, irreversible damage to the Turbomachine wheel according to the invention or the associated Drive motor, the gear, the brackets for this, etc. on simple Way can be prevented.
  • Hub outer part and the inner hub part are interlocked achieved that when the elastic spring force of the hub damping element is exceeded or if the same is worn - in particular after a long period of use Turbomachine wheel - the torque transmitting properties from the drive to the blades, i.e. between the shaft hub of the Turbomachine wheel and the blades remain guaranteed.
  • the turbomachine wheel according to the invention has two or more than two wing blades arranged equidistantly in the circumferential direction.
  • the hub damping element of the invention Turbomachine wheel can be annular or sleeve-shaped. It can be made from a cast elastomer, i.e. from a plastic or from consist of a rubber material. Likewise, it is possible that the hub damper has at least one spring element. This at least a spring element can, for example, as a ring spring or the like. be designed.
  • the wing blade damping elements can be annular. she can - like the hub damping element - from a plastic or consist of a rubber material. You can also use feathers such as Disc springs or the like, of sleeve elements made of an elastomer material or the like, be educated.
  • the wing-leaf damping elements are particularly advantageous if already Impacts or impacts on the blades due to uncontrolled hydraulic Conditions or properties of the respective medium partially intercepted, i.e. should be dampened to avoid shocks or blows in the area to reduce or to reduce the shaft hub of the turbomachine wheel minimize.
  • wing-leaf damping elements are also advantageous in known turbomachine wheels can be retrofitted.
  • known Turbomachine wheels are, for example Fluid machine wheels of submersible mixers, e.g. of the series "Maxiprop” and “Megaprop” by the applicant.
  • the turbomachine wheel according to the invention can advantageously are used for all types of impellers and propellers, for which the danger of an irregular hydraulic flow due to the medium consists.
  • the invention can Turbomachine wheel also with regular hydraulic flow Application.
  • the invention is used Turbomachine wheel especially with a submersible mixer or with a Pump such as a sewage, sludge, sewage or sewage pump or with a recirculation pump.
  • the invention Turbomachinery wheel is not on the last mentioned applications and Areas of application limited, as already stated.
  • FIGs 1, 2 and 3 show a first embodiment of the Turbomachine wheel 10 with a shaft hub 12, which is a hub inner part 14 and an outer hub part 16.
  • the hub outer part 16 has indentations 18 distributed equidistantly around the circumference, which are used to receive the Foot sections 20 of wing blades 22 are provided.
  • the wing blades 22 are with their foot sections 20 in the associated indentations 18 of the Hub outer part 16 fastened by screws, of which in the figures 2 and 3 only their center lines indicated by thin dash-dotted lines 24 are. These screws are evenly spaced along a pitch circle spaced apart.
  • the foot sections 20 of the wing blades 22 have one circular base or edge contour.
  • a hub damping element is located between the inner hub part 14 and the outer hub part 16 26 provided, for example by a cast Elastomer is formed.
  • the outer hub part 16 and the inner hub part 14 are together crossed.
  • the inner hub part 14 is radial protruding lugs 28 and the hub outer part 16 with inward oriented approaches 30 trained.
  • FIGs 4, 5 and 6 show a second embodiment of the Turbomachinery wheel 10.
  • This second training differs from the embodiment of the shown in Figures 1 to 3 Turbomachine wheel 10 esp.
  • Hub damping element 26 is provided, but that also between the heads 32 of the fastening screws 34, whose center lines are again designated with the reference number 24, and the inside 36 of the Bottom 38 of the indentations 18 wing-leaf damping elements 40 are provided are.
  • leaf damping elements 40 can also be found in those already on the market Turbomachine wheels 10 can be retrofitted to said To dampen vibrations or to avoid damage.
  • the shaft hub 12 can of course also be in one piece, i.e. the inner hub part 14 and the hub outer part 16 can then be formed in one piece.
