Definitions
- the invention relates to a hydraulic vane machine with the features of the preamble of claim 1.
- Such a vane machine is out EP 0 247 001 A2 known. It is designed as a vane pump which can be used to convey pasty foods, in particular sausage meat
- a vane machine that has a vane with a steel core surrounded by a plastic sheath is out DE 10 2011 116 869 A1 known.
- FR 1 315 068 A describes an internal combustion engine with a rotary piston, which is mounted in a stator.
- the rotary piston has a plurality of vanes, each of which can be displaced radially in a sliding guide.
- the vanes rest against an inner circumference of the stator and, with the rotary lobe, the stator and sealing plates, delimit an internal cavity at each axial end of the rotary lobe, the volume of which changes when the rotary lobe rotates.
- Each wing has on its radially inner side a contact surface which lies radially on the outside on a guide surface.
- DE 35 24 275 A1 shows a rotary piston type rotary piston machine with a central housing with a cylindrical drum.
- the cylindrical drum has several radial slides which can be displaced radially in radial slots.
- the radial slides rest on an inner circumference of the center housing.
- the radial slides delimit interstices closed with the central housing of the cylindrical drum, which continuously enlarge and reduce.
- Each radial slide has a contact surface on its radial outside, which abuts a building 8 radially outside.
- US 4,454,844 A shows a 4-cycle rotary piston machine with an eccentrically arranged rotor.
- the machine has a rotor structure with two rotors, which are arranged in a housing.
- the rotor structure has a plurality of vanes, which are each arranged radially displaceably in a guide.
- the wings rest on an inner circumference of the housing and, with the rotor structure and the housing, delimit working chambers, the volumes of which change when the rotor structure rotates relative to the housing.
- Each wing has a contact surface on its radial inside, which lies radially on the outside against a guide element.
- DE 2 316 529 A1 shows an engine in the form of an internal combustion engine or a hydraulic motor or a pump.
- the machine has a cylindrical barrel body with radial slots in which slides can be displaced radially.
- the sliders rest on an inner circumference.
- the slides have a control rod with a guide roller which engages in a guide curve of a stationary guide disk.
- the sliders are made of plastic with inner steel mesh reinforcement to achieve sufficient strength.
- a vane machine can, for example, be used as a booster pump in a reverse osmosis system and then acts as a water-hydraulic machine.
- the rotor is mounted eccentrically to the inner circumference of the stator. A point on the surface of the rotor then approaches the inner circumference once with one revolution until a minimum distance is reached, and then moves away from the inner circumference again until a maximum distance is reached.
- the vane machine is used as a pump, then an outlet opening for the respective working chamber is provided in the area of the minimum distance, from which water can then be dispensed under a higher pressure.
- the vane machine is used as a motor, there is a feed or feed connection in this area, at which water can be fed under pressure.
- the invention has for its object to have a certain freedom in the design of the inner circumference.
- the contact surface is formed on at least one axial end of the wing.
- the cam disc can thus be arranged on an axial end face of the rotor, so that the structure of the rotor is not disturbed or impaired by the use of the cam disc.
- the contact surface is formed in a recess at the axial end of the wing.
- the cam engages in this recess. It is therefore possible for the cam disc to somewhat cover the wings in the radial direction.
- the recess can have a radial extension that is greater than a maximum stroke of the wing.
- the cam disc covers the wings in the area of the recess over the entire stroke.
- the cam disc also serves to axially seal the wings, so that leakage can be avoided or at least kept small.
- the blades project axially beyond the rotor. You can then partially or even completely axially arrange the cam outside of the rotor, which has the advantage that the cam and the rotor do not interfere with each other.
- the recess preferably has an axial extent which corresponds to an axial thickness of the cam disk. In this case, it can be ensured that the wings rest outside the recess with their axial end on the side wall and inside the recess with their axial end on the cam. This results in a sealing surface over the entire height of the blades in every angular position of the rotor with respect to the stationary parts, which extends over the entire radial length of the axial ends of the blades. This ensures a relatively good seal.
- the cam disc preferably corresponds to the inner circumference of the stator minus twice the radial extent the wing plus twice the radial extent of the recess. This is a relatively simple design rule.
- the cam disk can be designed, so to speak, as a reduced copy of the inner circumference of the stator.
- the contact surface is preferably rounded. This keeps friction between the wing and the cam disc small. It is practically unavoidable that the wing tilts in the guide. Even if this tilting can be kept very small, problems could arise from this tilting. Such problems are reliably avoided by rounding off the contact surface.
- the rotor is mounted centrally relative to the stator and a course of a radial distance between the stator and the rotor has at least two maxima and two minima in the circumferential direction.
- the wings enter with their radial inside during an inward stroke into the cavity. Then the cavity is filled with water when the machine is operated. However, this is not critical because the pressure of the water in the cavity can adjust to an average.
- the wings have a core made of steel and a covering made of a plastic that interacts with steel with low friction.
- the rotor and stator can be made of steel.
- water since water has no lubricating properties, the friction reduction that is caused by a hydraulic oil in an oil-hydraulic machine is caused by the friction-reducing plastic.
- the plastic used for the coating is, in particular, materials from the group of high-strength thermoplastics based on polyaryl ether ketones, in particular polyether ether ketones, polyamides, polyacetals, polyaryl ethers, polyethylene terephthalates, polyphenylene sulfides, polysulfones, polyether sulfones, polyetherimides, polyamideimides, polyacrylates, phenol-urethanes, and phenol-urethanes, such as phenol-polyols Resins, or the like, where glass, graphite, polytetrafluoroethylene or plastic, in particular in the form of fibers, can be used as fillers. When using such materials, water can also be used as the hydraulic fluid.
- polyaryl ether ketones in particular polyether ether ketones, polyamides, polyacetals, polyaryl ethers, polyethylene terephthalates, polyphenylene sulfides, polysulfones, polyether
- each wing has a surface formed from the plastic which interacts with steel with low friction and the contact surface is at least partially formed from a steel, the cam plate being at least in one area against which the contact surface rests has steel formed with low friction interacting plastic surface.
- the cam plate being at least in one area against which the contact surface rests has steel formed with low friction interacting plastic surface.
- the cam disc is preferably formed in one piece with the side plate.
- it can be formed by a projection on the side plate.
- At least one side wall has at least one opening which is delimited radially on the outside by a web against which the wings rest. Also in the area of the opening it is achieved that the wings are supported radially on the inside and radially on the outside in the axial direction. Tilting of the blades in a direction parallel to the axis of rotation can thus be reliably avoided.
- a vane machine 1 has a stator 2 and a rotor 3, which are rotatably mounted with respect to one another by means not shown.
- the rotor 3 has a plurality of vanes 4, which are each radially displaceable in a guide 5 in the rotor 3.
- the wings 4 rest on an inner circumference 6 of the stator.
- a side wall 7 is arranged at each axial end of the stator. Openings 8, 9 can be provided in the side wall 7, which can be used for supplying or removing water. In Fig. 1 only one side wall 7 is shown.
- the stator 2 On the axially opposite end face, the stator 2 likewise has a side wall, which, however, is not shown. In this other side wall, the openings 8, 9 can possibly be omitted.
- the openings 8, 9 do not extend radially outward to the stator 2.
- Ridges 10, 11 are provided radially on the outside, against which the vanes 4 can rest in the axial direction when the rotor rotates. Also in the area of the openings 9, 10, the wings are supported radially inwards and radially outwards in the axial direction.
- a through opening 12 is provided in the rotor 3, through which a shaft can be guided, for example, by means of which the rotor 3 is rotatably mounted relative to the stator 2.
- the through opening 12 widens axially in the middle to form a cavity 13.
- the wings 4 enter with their radial inner sides 14 into the cavity 13 when they are pressed radially inward by the inner circumference 6 of the stator 2.
- a cam disk 15 is arranged on each of the two axial end faces of the rotor 3.
- the cam plate 15 can be fastened to the side wall 7 or can be formed in one piece with the side wall 7. It has a shape that corresponds to the inner circumference 6 of the stator, but in a reduced version, as will be explained in more detail below.
- the wings 4 each have a recess 16 at their two axial ends.
- the cam disc 15 engages in this recess 16.
- Each recess 16 has an axial extent which corresponds to the axial thickness of the cam plate 15.
- the vanes 4 protrude axially beyond the rotor 3 by this axial extent, so that it is possible to have the vanes 4 and the cam plate 15 flush with one another in the axial direction.
- the recesses 16 can have an extension in the radial direction that is greater than a maximum stroke of the wing.
- the cam 15 then covers the wings 4 over their entire radial stroke in the region of the recess 16.
- the inner circumference 6 of the stator is twice the radial Extension of the wings 4 is reduced. Double the radial extent of the recesses 16 is added.
- a cam disk 15 designed in this way ensures that the vanes 4 always lie against the inner circumference 6 of the stator 2 and ensure an adequate seal there.
- the wings 4 rest with their end faces either on the side wall 7 or on the cam plate 4, so that an adequate seal is also provided there.
- a sealing radially inwards results from the interaction of the wings 4 with the guides 5.
- the vane machine 1 shown there has two working cycles per revolution.
- Fig. 3 and 4th show the vane machine 1 in a perspective view.
- the same parts have the same reference numerals as in the 1 and 2 Mistake.
- Fig. 3 and 4th can be seen more clearly that the radial inner sides of the wings 4 are rounded in the region of the recesses 16, which form contact surfaces 17 of the wings 4 on the cam disk 15.
- the cam plate 15 is designed here as a separate element. However, it can also be formed in one piece with the side wall 7.
- cam 15 is designed as a separate element, then you can dimension its two end faces or pressure application surfaces on the two end faces, which can be defined, for example, by seals (not shown), in such a way that there is a force balance across the rotor in the axial direction. This allows you to minimize play and accordingly keep leakage small.
- the wings 4 have a core made of a steel and a covering made of a plastic which interacts with steel with low friction.
- the blades 4 are thus designed such that they can interact with the stator 2 and the guides 5 in the rotor 3 with low friction. A reduced friction also results on their end faces, which bear against the side wall 7 formed from steel.
- plastics from the group of high-strength thermoplastics based on polyaryl ether ketones, in particular polyether ether ketones can be used as plastics.
- Polyamides Polyamides, polyacetals, polyaryl ethers, polyethylene terephthalates, polyphenylene sulfides, polysulfones, polyether sulfones, polyetherimides, polyamideimides, polyacrylates, phenol resins, such as novolack resins, or the like, where glass, graphite, polytetrafluoroethylene or plastic can be used as fillers, in particular in fiber form . When using such materials, water can also be used as the hydraulic fluid.
- the cam disc 15 should also be provided with a corresponding plastic, at least in the area where the rotor 3 rests with its end face.
- the recesses 16 are expediently milled out of the wings 4 after the plastic has been applied .
- the rounded shape of the contact surface 17 also means that contact between the plastic of the wing 4 and the plastic of the cam plate 15 can be practically avoided.
- the wing 4 then also has an end face 18, which is formed by the recess 16, which likewise essentially consists of the steel of the core of the wing 4 exists. This surface 18 then bears axially against the cam plate 15, so that a pairing of plastic and plastic is avoided here too and a pairing of steel and plastic is achieved.
