Definitions
- the invention relates to an internal gear machine, in particular one Internal gear pump.
- Such machines are from numerous Publications known, for example DE 43 38 875 A1 or EP 0 563 661 A1.
- This pump has axially movable disks - so-called Axial disks attached to the rotating gear parts of the ring gear and of the pinion.
- These thrust washers are in the axial direction movable. They are derived from the working pressure Axial pressure pressed against the rotating gear parts. As a result, the gap between the housing and the toothing part compensated.
- Axial compensation is also required for use at high pressures necessary. Both axial pressure surfaces are mentioned Axial disks applied simultaneously; the associated with high pressure One side is under high pressure and the other side is under feed pressure pressurized, which is about 10 bar.
- the internal gear pump shown in Figure 1 comprises as essential Components a pinion 1 with an external toothing, a ring gear 2 with a Internal toothing, a filling of two filling pieces 3, 4, one 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. Through the two A dash-dotted straight line is drawn through the center points M1 and M2. This denotes a plane of symmetry, on its meaning below still to be discussed.
- the crescent-shaped space between the pinion 1 and the ring gear 2 is from filled in 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. How one see, the stop has two support surfaces 5.1, 5.2. The end faces of the two fillers 3, 4 are supported against the support surfaces 5.1, 5.2.
- the two filling pieces 3, 4 are also longitudinal in a manner known per se divided. They are thus made up of an inner part 3.1, 3.2 or 4.1, 4.2.
- the fillers 3, 4 could, however, just as well each 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. This is in the present case exactly in the plane of symmetry 7.
- FIGS. 3 and 4 show the following in detail: between the two walls of the housing 6 and the pinion 1 are located Axial disks 21, 22, respectively.
- Axial pressure fields 23, 24 each in the axial pressure plates 21, 22 themselves incorporated.
- the axial fields 25, 26 incorporated into the walls of the housing 6.
- the axial pressure fields mentioned can also be seen in FIG. 6 - see there the axial pressure fields 23.
- the axial disks 21, 22 have on their inner sides, that is those sides which face the pinion 1, control fields 27, 28 on. See also Figure 7.
- the control fields 27, 28 point according to the Invention a special feature. They are slotted - see the slots 30 in Figure 7. The arrangement is such that the recesses formed by the slots 30 with the Control fields 27, 28 formed recesses communicate. Furthermore through bores 31, 32 are provided - see FIGS. 6 and 7.
- Control slots 30 are designed such that the volume through them recesses created - from the top of each control slot increases towards the control panel. This builds up in the Control panels are relatively slow to apply pressure, so no excessive Wear or even destruction of the machine occurs.
