Definitions

  • the invention relates to a rotary displacement machine with at least two externally toothed conveyor gears for conveying a fluid and with at least two feed channels with feed openings in the area of the conveyor gearwheels Feeding the fluid to the feed gears, each feed mouth so is formed that the intended operation of the Rotary displacement machine fluid exiting the feed mouth either only to the teeth of a single feed gear or only to the teeth can get such conveyor gears that rotate in the same direction.
  • the invention further relates to a housing for such a machine.
  • Rotary displacement machines of the type in question here can be used both as Pumps, i.e. as pressure generators, as well as motors, i.e. as pressure consumers, be used. If the rotary displacement machine is used as a motor, then the fluid conveyed is usually a hydraulic oil. Will the Machine used as a pump, different fluids, but especially Liquids such as oil, water and the like are promoted.
  • a rotary displacement machine with the features mentioned is from GB 2 161 861 known.
  • a similar machine is also shown in FR 948 868.
  • rotary displacement machines are e.g. from DE 195 33 215 A1 or US 1,250,927 in the form of gear pumps with two in one housing arranged conveyor gears known, each one of the conveyor gears is driven by a drive gear arranged in the housing.
  • Gear pumps are known from DE 196 38 332 A1 and DE 328 963 C1 two conveyor gears arranged in a housing are also known, in each of which one of the feed gears is guided out of the housing Shaft is driven.
  • the object of the invention is particularly easy running, easy-to-seal rotary displacement machine of low weight specify.
  • turbulence in the feed area i.e. the area in which the medium to be conveyed from the feed channels into the delivery chambers is largely avoided and the filling of the delivery chambers is improved become.
  • the task is solved by a rotary displacement machine at the beginning mentioned type, in which the feed gears in the form of by one fixed axis rotatably mounted conveyor toothed rings are formed.
  • toothed rings instead of classic gears, there are toothed rings, sometimes called Gear rings are referred to used to promote the fluid. in the In the following, these toothed rings are therefore referred to as conveyor toothed rings.
  • the toothed rings can be stored in a particularly simple manner, and at Gears necessary rotating shafts can be omitted. Depending on the size and Training of the toothed rings, one bearing per toothed ring can suffice during rotating shafts must always be stored at both ends.
  • a rotary displacement machine designed according to the invention have two intermeshing feed gears, each then Conveyor gear is assigned at least one feed mouth.
  • Conveyor gear is assigned at least one feed mouth.
  • a basic idea in the rotary displacement machine according to the invention is Appropriate steering of the fluid flows, resulting in a significant improvement the efficiency of rotary displacement machines can be achieved.
  • Rotary displacement machine In a structurally particularly simple embodiment of a Rotary displacement machine is only one feed channel with a number of Feed mouths are provided, which corresponds to the number of feed gears.
  • a such a rotary displacement machine can be in a simply designed housing be arranged, which is only an inlet for introducing fluid into the Must have feed channel.
  • a plurality of feed channels are provided, preferably as many as Feed gears are provided.
  • Each feed channel can then have its own Inlet be provided, so that such a machine simultaneously with fluid
  • Different pressure sources can be operated when used as a motor is, and can suck fluid from different reservoirs if they are as Pump is used.
  • the rotary displacement machine can then also advantageously serve as a mixer.
  • the feed gears are in one Housing arranged in which the feed openings and / or the or Feed channel (s) are formed by appropriate shaping. On separate components and / or seals to form the feed openings and Feed channels can then be dispensed with.
  • At least one connecting channel is provided, which Combing area with at least one between the teeth of a feed gear and directly or indirectly connects the delivery chamber formed inside the housing.
  • Such a connecting channel then enables the transfer of fluid from the Combing area in at least one between the teeth of a conveyor gear formed delivery chamber, so that the filling of the chamber is further increased.
  • Circulating displacement pumps known to date are partial in the combing area connection channels are also available, but these are with the respective Reservoir from which fluid is sucked, connected, so that at the previous known machines the pressure generated in the combing area is used to to convey the fluid to where you actually want to extract it.
  • connection channel (s) can be connected via corresponding lines or directly connected to one or more delivery chambers. Especially It is advantageous to use the appropriate connection channel (s) Forming the housing to form, in particular in that on the Conveyor gears surrounding the inside of the housing one or more grooves be introduced.
  • a gear ratio between the drive gear and driven (driven) conveyor gear greater than 1: 3 and lies especially between 1: 4.5 and 1: 6.5. This not only reduces that in the case of Use as a pump to apply torque, it has also been shown that such a gear ratio is advantageous for reducing the Running noise contributes.
  • Rotary displacement machine shown, in which two here as conveyor toothed rings 12th and 14 designed feed gears are arranged in a housing 16 in such a way that they comb each other in one area.
  • the conveyor toothed rings can each be rotated about a fixed axis 18 or 20 stored.
  • Balls 22 or 24 provided, only a few balls for reasons of clarity were drawn, of which only one is provided with a reference number has been.
  • Drive gear 30 which meshes the conveyor toothed ring 12 and approximately has six times smaller diameter than the same conveyor toothed ring 12.
  • the drive gear 30 is in the housing 16 between the Conveyor toothed rings 12 and 14 are arranged so that it is against incoming fluid is encapsulated.
  • Feed channels 32 and 34 there are two separate ones for supplying fluid Feed channels 32 and 34 are provided, the feed channel 32 of the conveyor toothed ring 12 and the feed channel 34 is assigned to the conveyor toothed ring 14 and only in each case forms a feed mouth.
  • On the outside of the housing 16 are per se Known and therefore not shown connections for introducing fluid into the Feed channels 32 and 34 are provided.
  • a Outlet 36 To discharge the pumped fluid is a Outlet 36 provided.
  • FIG. 2 shows a section of a housing 40 for a Orbital displacement machine shown in which, as by the dashed lines 42 and 44 indicated, two feed channels for feeding fluid to be conveyed are formed.
  • the feed channels have one common inlet 46, but open into two separate areas 48 and 50 of the Housing, which each hold a feed gear or Serve toothed ring. there is also an outlet 52 in the housing for drainage conveyed fluids provided.
  • FIG. 3 shows a schematic cross section through one in its entirety with 60 designated rotary displacement machine with two intermeshing Feed gears 62 and 64.
  • the feed gears are in a housing 66 arranged in which two connected to a common inlet 68 Feed channels 70 and 72 are formed, with the feed channel 70 on the feed gear 62 and the feed channel 72 opens on the conveyor gear 64.
  • the housing has also via an outlet 74.
  • the special feature of this embodiment according to the invention is the dotted arrows 76, 78, 80 and 82 depicting the through connecting channels enabled fluid flow from the meshing area in which the feed gears 62 and 64 comb with each other to an area where the between the Housing inner wall and the teeth of each conveyor gear formed Swipe the funding chambers, hint.
  • the Connection channels can e.g. through grooves on the conveyor gears facing inside of the housing can be realized inexpensively.
