Definitions
- the invention relates to an internal gear machine, in particular an internal gear pump.
- Such machines are from numerous items.
- This pump has axially movable disks - so-called axial disks, which adjoin the rotating toothed parts of the ring gear and the pinion. These axial disks are movable in the axial direction. They are pressed against the rotating gear parts by means of an axial pressure derived from the working pressure. This compensates for the gap between the housing and the toothed part.
- a constant pump can be turned into a control pump by means of speed control.
- Such a pump has considerable advantages over a control piston pump. It develops a much lower noise level during operation, has a longer service life and consumes less
- FIG. 1 shows a sectional view perpendicular to the axis
- Figure 2 shows a circuit with an inventive
- Figure 3 shows an axial section of a section of a
- FIG. 4 again shows an axial section of a detail from an internal gear pump in a second version.
- FIG. 5 shows an axial disk in an axial section - corresponding to the illustrations in FIGS. 3 and 4.
- Figure 6 is a top view of the left surface of the thrust washer of FIG.
- FIG. 7 is a top view of the right side of the axial disk according to FIG.
- the internal gear pump shown in FIG. 1 comprises as essential components a pinion 1 with an external toothing, a ring gear 2 with an internal toothing, a filling of two filling pieces 3, 4, a stop pin 5 and a housing 6.
- Pinion 1 is mounted eccentrically with respect to ring gear 2. See the center point M1 of the pinion and M2 of the ring gear. A dash-dotted straight line is laid through the two center points M1 and M2. This denotes a plane of symmetry, the meaning of which will be discussed further below.
- the crescent-shaped space between the pinion 1 and the ring gear 2 is filled with a filling.
- the filling comprises the two filling pieces 3, 4.
- the stop 5 is mounted in the housing 6 with a certain amount of play. As you can see, the stop has two support surfaces 5.1, 5.2. The end faces of the two filler pieces 3, 4 are supported against the support faces 5.1, 5.2.
- the two filling pieces 3, 4 are also divided lengthways in a manner known per se. They are thus made up of an inner part 3.1, 3.2 or 4.1, 4.2. However, the filler pieces 3, 4 could just as well consist of a single part.
- the housing has two pressure connections 6.1, 6.2.
- the two pressure connections are on both sides of the plane of symmetry 7.
- the housing also has a leakage outlet 6.3. In the present case, this lies exactly in the plane of symmetry 7.
- FIGS. 3 and 4 show the following in detail: there are axial disks 21, 22 between the two walls of the housing 6 and the pinion 1.
- the first version according to FIGS. 3 and 4 shows the following in detail: there are axial disks 21, 22 between the two walls of the housing 6 and the pinion 1.
- the axial fields 25, 26 are incorporated into the walls of the housing 6.
- the named axial pressure fields can also be seen in FIG. 6 - see the axial pressure fields 23 there.
- the axial disks 21, 22 have control fields 27, 28 on their inner sides, that is to say those sides which face the pinion 1. See also FIG. 7.
- the control fields 27, 28 have a special feature according to the invention. Namely, they are provided with slots - see the slots 30 in FIG. 7. The arrangement is such that the recesses formed by the slots 30 communicate with the recesses formed by the control fields 27, 28.
- Through holes 31, 32 are also provided - see FIGS. 6 and 7.
- control slots 30 are designed such that the volume of the recesses created by them increases from the top of each control slot to the control field. This builds up in the
- Control fields only a relatively slow pressure so that no excessive wear or even destruction of the machine occurs.
- a so-called axial piston can be provided between the axial pressure fields 23, 24 and the relevant walls of the housing 6, or between the axial pressure fields 25, 26 and the axial disks 21, 22. This has essentially the same shape as the relevant control field 23 itself shown in FIG. 6.
