- Housing part of the transmission is arranged.
- the advantage here is that the spatial area of the transmission is separated by means of the bearing from the spatial area of the gear pump arrangement. Because this arrangement is attachable to the shaft end.
- at least one housing part of the conveying device receives a bearing of the shaft and is also housing-forming for a transmission, which comprises a toothed part rotatably connected to the shaft.
- the conveyor has an integrated transmission.
- the gear housing includes not only gearing parts of the transmission but also the
- the feed channel and / or the discharge channel has a recess which extends in the circumferential direction over less than 180 °
- the recess is substantially semicircular and / or
- Control disk which is arranged axially adjacent to the channel regions, an axially continuous recess of the control disk over the supply or AbGermankanal Scheme can be positioned - depending on the rotational position.
- supply channel and discharge channel are spaced from each other.
- the housing part has a sleeve-shaped portion, to which a cover part is tightly and detachably connectable, so that the conveyor is surrounded by the housing forming part and cover part.
- the advantage here is that the sleeve-shaped portion can be shortened depending on the desired flow rate and thus depending on the desired axial length.
- a plurality of gears axially in succession on the shaft rotatably provided and a plurality of gears are arranged with the other gear on a common axis one behind the other, in particular wherein the housing part has a sleeve-shaped portion to which a cover member is tightly and detachably connectable, so that the conveyor, comprising the gears, is surrounded by the section and cover part forming the housing.
- the gear pump assembly is integrated housed in the gear housing.
- the conveyor is arranged at an axial end portion of the shaft and is connected at the other axial end portion with a rotor shaft directly or via a coupling device, in particular wherein the rotor shaft drives the shaft and thus rotatably connected thereto provided gear of the conveyor.
- Gear promotion at the shaft end integrated in the housing of the transmission is providable and does not need its own drive but runs along with the shaft.
- End region of the shaft is arranged.
- the advantage here is that a shaft end pump can be realized.
- the number of axially successively arranged gears is selected, wherein the number 1 or larger is selected, a housing part of a blank, in particular raw casting, with a
- sleeve-shaped portion ie tubular extension is made by the section is cut to length according to the selected number, in particular cut off and / or turned off.
- sleeve-shaped, ie tubular housing portion can be accommodated.
- FIG. 1 shows a side view of the shaft end pump arrangement according to the invention.
- FIG. 2 shows an associated oblique view.
- FIG. 3 shows an associated plan view.
- FIG. 4 shows a cross section.
- FIG. 5 shows a further outward cross-section.
- cross section is shown, which lies between the cross sections of Figures 4 and 5.
- FIG. 8 shows a cross section twisted about the shaft axis for this purpose.
- a shaft 47 is mounted via a bearing 48 in the housing part 3.
- the housing part 3 is preferably associated with a transmission and the shaft 47 is a driving shaft of the transmission, so a fast rotating operable shaft.
- the shaft 47 is a driving shaft of the transmission, so a fast rotating operable shaft.
- At an axial end region of the pump assembly is provided integrated.
- the pumping arrangement operates in the manner of a gear pump.
- a gear 53 is rotatably connected to the shaft 47 at the shaft end, which is in engagement with a gear 52 which is mounted on an axis in a connecting plate 43 with recesses (45, 46) and connection openings (20, 40, 41 , 42) and is mounted in a bearing plate 70.
- the engaged gears (52, 53) convey a medium, such as lubricant of the transmission or water from an upstream feed channel 55 to a discharge channel 56.
- a medium such as lubricant of the transmission or water from an upstream feed channel 55 to a discharge channel 56.
- Each of these channels leads in the axial direction through a respective hole 65 of a control disk 61 in a respective recess 44 and 45 respectively.
- the control disk 61 is rotatably supported by means of a bearing 63 on the shaft 47. Due to friction, the control disk 61 is taken in the respective direction of rotation of the shaft 47.
- the control disk 61 is only in one provided for them
- the medium After striking the control disk 61 to the stop disk 66, the medium is supplied in the feed or discharge channel depending on the rotational position of the control disk 61. Because the hole 65 is located axially above the recess 45 or alternatively over the recess 46 of the connection plate 43. These recesses extend in the circumferential direction in each case by less than 180 °.
- a flow through possibility between recess 44 and a hole 65 of the control disk 61 or between recess 45 and a hole 65 of the control disk 61 is effected.
- the removal of the medium in the other of the recesses (44, 45) is changed. But since the direction of rotation of the
- Gear wheels (52, 53) is changed, the conveying direction is also changed, so that the medium is always supplied via the connection opening (41, 42) to the recess 45 and is led out via the recess 44 into the connection opening (20, 40).
- connection opening 41 of the two merged connection openings (41, 42) serves to selectively supply the medium from an internal piping or external piping.
- lubricant is then drawn from the oil sump of the transmission and from the gear pump comprising the gears
- the output side conveyed into a pipe from which lubrication points are fed with the conveyed lubricant.
- the engagement region of the gears is lubricated and / or a bearing lubricated.
- the medium is supplied from an external pipe and discharged from another pipe.
- Lubricant is then returned to the transmission and can be used to lubricate and / or cool parts of the transmission.
- the spacing of the recesses 44 and 45 in the circumferential direction is smaller than the angular amount by which the control disk 61 can reciprocate.
- the control disk has on its stop side a small groove 62 extending in the axial direction, which allows an axial outflow of the amount of medium to be displaced during the rotation direction change.
- a faster switching of the gear pump is possible.
- the recesses 46 screws are axially feasible, which are also used as a safeguard against rotational movement of the connecting plate 43.
- the gear pump is also modular, so that it can be produced with scalable performance.
- the sleeve-shaped portion 1 of the housing part 3 is tapped from the blank at such a location that the desired length is reached.
- the parts are provided according to the desired performance.
