Definitions

  • the invention relates to a gerotor pump for liquid media with a arranged in a pump housing, driven by a drive shaft wheelset.
  • Toothed ring pumps are self-priming liquid pumps with a very compact design, which produce a continuous pump flow rate, which is relatively insensitive to the pressure fluctuations occurring in the connecting lines.
  • the impeller set used in gerotor pumps consists of an externally toothed inner rotor, which is rotatably connected to the drive shaft, and an internally toothed outer rotor which is rotatably mounted in a cylindrical chamber of the pump housing so that the teeth of the inner rotor, which is mounted eccentrically to the outer rotor and having fewer teeth than the outer rotor, partially mesh with the teeth of the outer rotor.
  • kidney-shaped pump chambers pressure and suction kidneys
  • connection channels arranged pressure and suction connection lines and ensure that the liquid to be pumped from the suction line via the wheelset in pressure connection line is pressed.
  • Toothed ring pumps are used in the design of gerotor pumps, for example, as an electric motor driven fuel pumps, which is housed in a housing in addition to the gerotor pump at the same time a DC motor.
  • Such a gear pump used as a fuel pump is known whose axial play with the aid of a gerotor axially evasive adjacent arranged, ring surface side pressurizable, axial Abdichtringhunt, with recesses for fluid inlet and outlet, can be varied.
  • gerotor pumps in the design of gerotor pumps are also housed in separate pump housings.
  • the pump housing require due to the built-in these construction and functional elements, such as the required seals, the bearings for drive shaft and outer rotor, the pump chambers and their connection channels, etc., a high manufacturing and assembly costs, which due to the efficiency severely affecting gap geometry with smaller As the size increases, it increases disproportionately.
  • the housing of the gerotor pumps such as those of gerotor pumps, are also assembled from several components.
  • the arranged between the adjacent components Elastdomerdichtonne are also used to compensate for tolerances.
  • residual stresses occur at such an elastic tolerance compensation, which then lead to moments of friction on the front sides of the wheelset, or if between the adjacent components remain tolerances caused by gaps, leakage losses may occur at the front of the wheelset, the efficiency, in particular in very small-built gerotor pumps (such as for small gerotor pumps), strongly affect.
  • the invention is therefore based on the object to develop a highly dynamic gerotor pump, which eliminates the aforementioned disadvantages of the prior art, i. Even with very small size is inexpensive to produce, it always robust, reliable and trouble-free under all operating conditions and even in a small size (eg with external dimensions of about 40 mm x 40 mm x 40 mm and a flow rate of about 8 l / min ) always reliably ensures a high overall efficiency.
  • ring gear pump in the design of a gerotor pump has a plurality of housing parts formed pump housing 1 in which a driven by a drive shaft 2 wheelset 3 is arranged, which consists of a rotatably connected to the drive shaft 2 externally toothed inner rotor 4 and an internally toothed outer rotor 5 which rotates is mounted in a cylindrical rotor bearing 6 of the pump housing 1.
  • a suction kidney 8 and in the pressure region of the pump housing 1 are arranged in the suction region of the pump housing 1.
  • the suction kidney 8 is connected to the arranged in the pump housing 1 SauganQuerykanal 10 and the pressure kidney 9 with the arranged on the pump housing 1 pressure port channel 11 so that the liquid to be pumped from the suction port 10 via the wheelset 3 is pressed into the pressure port channel 11.
  • a bearing bore 14 is arranged, in which the drive shaft 2 of the wheelset 3 is rotatably mounted.
  • the control piston 17 is arranged eccentrically on the balance piston 13, in the region of the pressure kidney / n 9.
  • a leveling pin 23 is arranged on the balance piston 13 which is arranged axially displaceably in a arranged next to the control piston guide pin guide bore 24, wherein in addition to the pin guide bore 24, an outlet bore 25 is arranged, which via a return passage 26 with the pin guide bore 24 and the / the Saugniere / n 8, and the suction port 10 is connected.
  • Characteristic is how in the Figures 2 . 3 and 4 shown that the drive shaft 2 on the one hand in the bearing bore 14 on the balance piston 13 and On the other hand, is mounted in a bearing seat 35 in the bearing housing 34 of the pump housing 1, wherein both between the bearing bore 14 on the balance piston 13 and the pressure kidney 9 on the balance piston 13, as in the FIG. 5 shown, and also between the bearing seat 35 in the bearing housing 34 of the pump housing 1 and the pressure kidney 9 in the bearing housing 34 of the pump housing 1, as in the FIG.
  • This arrangement ensures, under operating conditions with minimal manufacturing effort, a robust, reliable, trouble-free, safe and low-friction displacement of the compensating piston 13 while at the same time optimally sealing the compensating piston 13 in the compensating piston guide 12.
  • This control piston sealing ring 33 causes a reliable, störunan administrate, dynamic displacement of the balance piston thirteenth
  • the pump housing as in the FIGS. 1 to 4 shown, constructed in a modular manner and sandwiched together, and from a bearing housing 34 with a bearing seat 35, a seal seat 36, a suction kidney 8, connected to this return flow channel 26, connected to the suction kidney 8 Saugan gleichkanal 10 and between the chamber with the Sealing seat 36 and the suction kidney 8 and the Saugan gleichkanal 10 arranged remindströmkanal 26, a pressure kidney 9 and connected to this pressure connection channel 11 and connected to the pressure kidney 9 and or the pressure port channel 11 pressure channel 18, a seal seat 36 for receiving a shaft seal 38, a Ring groove 37 for receiving a sealing ring 39 (O-ring) and a plurality of threaded holes 40 consists.
  • a work casing 41 having through holes 42 is disposed adjacent thereto; in which the wheelset 3 is mounted, this work housing 41 is adjacent a control housing 43 with mutually arranged annular grooves 37; a plurality of through holes 42, the balance piston guide 12 and the control piston guide 15 is disposed adjacent to this control housing 43 then a housing cover 44, again with through holes 42, and in the final assembly state in the annular grooves 37 each have a sealing ring 39 (O-rings) is arranged , wherein the through holes 42 in the final assembly state are aligned with each other, and the sandwich-shaped pump housing 1 is clamped over the entire surface by means of dowel sleeves 45 and through-connection screws 46 along the side walls facing each other.
  • O-rings sealing ring 39
