- the invention relates to a pump or a motor for liquid or gaseous media according to the preamble of the main claim.
- a known machine of this type (DE OS 42 41 320)
- the working part is driven via the shaft, wherein the work spaces between the work surfaces to promote the medium reduced according to a machine with spur gearing, or be increased.
- such a machine can also serve as a motor by medium is pumped into the work spaces under pressure, which generates a drive of the shaft by enlarging the work spaces.
- two working parts are rotated in the machine housing with correspondingly high demands on the pivot bearing and thrust bearing and with a significant performance limitation in terms of working pressure.
- the problem underlying the invention has for its object a pump or a motor for liquid or gaseous media, namely to develop a related machine, with the much higher working pressures of the media without disadvantage are acceptable and can be produced without a considerable manufacturing effort.
- the machine according to the invention with the characterizing features of the main claim and the dependent claims 10, 13 and 15 has the advantage that with a simple structure and correspondingly low cost, a machine for high working pressures is created in the advantageous effect of the known machines by radial load disadvantageous Pressures are now predominantly diverted into the more easily controllable axial direction. Due to the stationary arrangement of the other working part opposite the working surface delimiting working surface, bearing forces of a second working part also fall away, so that only the working part has a bearing surface towards the shaft on the oblique sliding plane and predominantly only the shaft has an axial bearing and only a small extent or in particular according to claim 15 must have no loaded radial bearing. The rotation of the shaft corresponds to the tumbling of the working part.
- the central axis of the stationary working surface is equal to the axis of rotation of the shaft.
- the partially tumbling inner wall receiving the tumbling working part merges into a cylindrical opening of the housing, the diameter of which corresponds to the diameter of the working part.
- the central axis of the stationary working surface is arranged coaxially to the shaft, on the one hand results in a favorable Auflagerung the working part on the static work surface, but also a working space separating large teilkugelige overlap area between the working part and the housing.
- the teeth of the oppositely arranged spur toothing formed as a cycloid toothing with power and Absperrteil with a cycloidal development of the tread.
- a configuration is known (DE 42 41 320), but in an embodiment in which the opposing work surfaces rotate in each case.
- the advantages of cycloidal processing are retained if only as in the invention, a work surface rotates. The advantages of cycloidal processing as such can be seen in the prior art.
- valves plate valves serve as valves plate valves with an outer and an inner ring having holding part and arranged between the rings, attached to one of the rings resilient valve plates.
- Such plate valves are extremely inexpensive to produce and work in the manner of a check valve.
- the shaft to the inclined sliding plane with respect to its stored portion toward an enlarged diameter, wherein in the step formed in the shaft serving as an inflow or outflow co-rotating channels run.
- the co-rotating channels corresponding openings in the working surface of the working part are present, which are controlled by the mouths of the channels in the inclined sliding plane.
- the shaft for forwarding the liquid or gaseous media from and to the workrooms a running in the shaft connecting channel to radial loads on the shaft by the fluids to both the housing as also to the pivot bearing to avoid.
- this embodiment plays a crucial role, since only by radial relief of the bearing forces of the shaft, the working pressure and thus the power range of the machine can be increased accordingly.
- openings are present at the bottom of the work spaces, which leads to a slated sliding plane and back of the Lead working part existing collecting space, wherein the collecting space is closed radially outward and leads directly to the connecting channel.
- Material tapers present, so as to compensate for the formation of the inclined plane without mass balance resulting unilateral mass accumulation by material tapers. This avoids that one-sided mass accumulations in the region of the inclined plane on the shaft creates unilateral radial forces.
- FIG. 2 is a view of the machine of FIG. 1 according to the arrow B,
- FIG. 4 shows a longitudinal section of the machine according to FIG. 1 with a first variant of the working part
- FIG. 5 shows a longitudinal section through a working part corresponding to the section C-C in Fig. 6,
- FIG. 6 is a view corresponding to the arrow D in Fig. 5,
- FIG. 9 is a view of the pump housing of FIG. 8 corresponding to the arrow F fifth
- valve plate 10 is a plan view of a valve plate
- valve plate of FIG. 10 in a perspective view
- Fig. 12 shows a second variant of the embodiment and Fig. 13, the shaft of this variant in perspective view.
- FIG. 1 an embodiment of the invention is shown in longitudinal section, as it is then shown in Fig. 3 in a perspective view.
- This is a machine that can be used depending on the application as a pump or motor for liquid or gaseous media, which, as particularly Fig. 3 removable, the cross section of the mounting housing 1 is cylindrical in order to use the machine in corresponding holes can ,
- round cord rings 2 form the required seal of the mounting housing 1, to which the machine receiving part, such as a pipe but also a hole in a machine receiving this machine.
- a shaft 4 is rotatably supported via a radial bearing 3, wherein the shaft is slightly loaded in the axial direction via a leaf spring 5 and a locking ring 6 and is correspondingly displaceable.
- a round cord ring 7 between shaft 4 and a housing insert 8, which is supported via a thrust bearing 9 on the mounting housing 1 and on which the leaf spring 5 acts.
- the housing insert 8 is entrained with leaf spring 5 and O-ring 7 for reasons of friction, wherein the housing insert 8 on its side facing away from the thrust bearing 9 has a labyrinth seal, which partially engages in corresponding recesses of the mounting housing.
- a non-co-rotating working space housing 10 is arranged coaxially with the shaft 4 centrally and sealed by a O-ring 11 to the installation housing 1 out.
- This working space housing 10 accommodates a working space 12, which is bounded on the other hand by a rotating working part 13.
- the shaft 4 has on the side facing the working part 13 an inclined sliding plane 14, so that a rotation of the shaft 4 leads to a tumbling of the working part 13.
- the glide plane 14 facing away from the end face of the working part 13 is toothed in the manner of a cycloid toothing, which engages in accordance with existing in a working housing 10 static teeth in the opposite wall surface of the working space 12.

- the working part 13 also has on its side facing the surface 16 a corresponding partial spherical surface 17, as well as a larger diameter 15 of the partial spherical surface section Due to this spherical overlap not only is there a very favorable distribution of the axial forces of the shaft 4 on the working space housing 10, but there is also a very favorable separation of the working space to working space or working space to other machine channels and this particular during the Operation, ie the Taumeins of the working part 13th
- the working space housing 10 is fastened via a screw ring 19 in the installation housing 1, wherein a valve plate 20 is clamped between the screw ring 19 and the working space housing 10.
- connection channels 21 are arranged for the working medium centrally symmetrical about an axis X of the machine, leading to the work spaces 12.
- the axis X is at the same time the axis of rotation of the shaft 4 and passes through the center M of the spherical surfaces accordingly.
- annular space 23 To the working spaces 12 there is a connection via control channels 22 to a shaft surrounding the annular space 23 for the working fluid, the annular space 23 depending on the application serves as inflow or outflow channel.
- this annular space 23 communicates via radial channels 24 with an outer annular space 25 in connection, as particularly Fig. 3 can be removed.
- an annular space 25 is then brought into coincidence with at least one channel for the medium.
- the illustrated in Fig. 4 first variant of the embodiment has only a pin 26 on the working part, which is inserted into a bore 27 of the shaft, said pin coaxially runs to the axis of the working part.
