Definitions

  • the invention relates to a hydraulic vane machine with a stator and a rotor having a plurality of vanes, which are each radially displaceable in a guide in the rotor, abut against an inner circumference of the stator and with the rotor, the stator and one side wall at each axial end of the rotor limit working chambers whose volumes change with rotation of the rotor relative to the stator.
  • Such a vane machine is off US Pat. No. 6,684,847 B1 known.
  • the wings are provided at both axial ends with projections which are respectively guided in grooves provided in the stator. The course of the grooves determines the movement of the wings.
  • Such a vane machine can be used for example as a boost 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. One point on the surface of the rotor then once approaches the inner circumference in one revolution until a minimum distance is reached, and then moves away from the inner circumference until a maximum distance is reached. If the vane machine is used as a pump, then an outlet opening for the respective working chamber is provided in the region of the minimum distance, from which then water can be discharged at a higher pressure. If the vane machine is used as a motor, then there is a feed or supply port in this area, can be fed to the pressurized water.
  • the invention has for its object to have a certain freedom in the design of the inner circumference. This object is achieved in a hydraulic vane machine of the type mentioned above in that each wing has on its radially inner side a contact surface which rests radially outward on a cam.
  • the abutment surface is formed on at least one axial end of the wings.
  • the cam can arrange the cam 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.
  • the abutment surface is formed in a recess at the axial end of the wing. In this recess engages the cam. This makes it possible that the cam covers the wings slightly in the radial direction.
  • the wings project axially beyond the rotor.
  • the recess has a radial extent that is greater than a maximum stroke of the wing.
  • the cam thus covers the wings in the region of the recess over the entire stroke.
  • the cam thus serves with the axial sealing of the wings, so that leakage can be avoided or at least kept small.
  • the recess has an axial extent corresponding to an axial thickness of the cam.
  • the wings abut outside the recess with its axial end on the side wall and within the recess with its axial end on the cam. This results over the entire height of the wings in each angular position of the rotor relative to the stationary parts a sealing surface which extends over the entire radial length of the axial ends of the wings. This ensures a relatively good tightness.
  • the cam corresponds to the inner circumference of the stator reduced by twice the radial extent the wing plus twice the radial extent of the recess. This is a relatively simple design rule. You can form the cam so to speak as a reduced copy of the inner circumference of the stator.
  • the contact surface is rounded. This keeps friction between the wing and the cam small. It is practically unavoidable that the wing tilts in the guide. Although this tilting can be kept very small, problems could arise as a result of this tilting. Such problems are reliably prevented by the rounding of the contact surface.
  • the rotor is mounted centrically relative to the stator and a profile of a radial distance between the stator and the rotor has in the circumferential direction at least two maxima and two minima.
  • the rotor has a passage opening, which widens axially inward to a cavity, for receiving an axle.
  • the cavity serves to reduce the mass of the rotor.
  • the wings enter with their radial inner side in an inward stroke into the cavity. Then, while the cavity is filled with water when the machine is operated. But this is not critical, because the pressure of the water in the cavity can adjust to an average value.
  • the wings on a core of a steel and a coating of a steel friction-co-operating plastic.
  • the rotor and the stator can be made of steel. Since water has no lubricating properties, the friction reduction caused by a hydraulic oil in an oil-hydraulic machine is in this case effected by the friction-reducing plastic.
  • 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, polyethersulfones, polyetherimides, polyamideimides, polyacrylates, phenol resins, such as novolak, are used as the plastic for the coating Resins, or the like, wherein as fillers glass, graphite, polytetrafluoroethylene or plastic, in particular in fiber form, can be used. When using such materials, water can also be used as hydraulic fluid.
  • each vane in the region of the guide has a surface formed from the plastic with a low-friction cooperating plastic surface and the abutment surface is at least partially formed of a steel, wherein the cam at least in an area in which abuts the contact surface, a from a Having formed with plastic friction co-operating plastic surface.
  • the cam at least in an area in which abuts the contact surface, a from a Having formed with plastic friction co-operating plastic surface.
  • the cam is formed integrally with the side plate. It may for example be formed by a projection on the side plate.
  • At least one side wall has at least one opening which is bounded radially on the outside by a web on which the wings abut. Also in the region of the opening is thus achieved that the wings are supported in the axial direction radially inward and radially outward. A tilting of the wings 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 to each other by means not shown.
  • the rotor 3 has a plurality of wings 4, which are each radially displaceable in a guide 5 in the rotor 3.
  • the wings 4 abut against an inner periphery 6 of the stator.
  • a side wall 7 is arranged.
  • openings 8, 9 may be provided, which can be used for the supply or for the discharge of water.
  • Fig. 1 only one side wall 7 is shown.
  • On the axially opposite end side of the stator 2 also has a side wall, which, however, is not shown. In this other side wall you can omit the openings 8, 9 under certain circumstances.
  • the openings 8, 9 extend radially outward not quite to the stator 2. Rather, radially outward webs 10, 11 are provided, on which the wings 4 can rest in the axial direction when the rotor rotates. Also in the region of the openings 9, 10 so the wings are supported radially inward and radially outward in the axial direction.
  • a through hole 12 is provided, through which, for example, a shaft can be guided, with which the rotor 3 is rotatably mounted relative to the stator 2.
  • the passage opening 12 widens to a cavity 13.
  • the wings 4 enter with their radial inner sides 14 in the cavity 13 when they are pressed by the inner periphery 6 of the stator 2 radially inward.
  • a cam 15 is arranged in each case.
  • the cam 15 may be fixed to the side wall 7 or formed integrally 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 its two axial ends. In this recess 16, the cam 15 engages. Each recess 16 has an axial extent corresponding to the axial thickness of the cam 15. The wings 4 are about this axial extent axially over the rotor 3, so that it is possible to make the wings 4 and the cam 15 in the axial direction flush with each other.
  • the recesses 16 may have an extent in the radial direction, which 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 about twice the radial Extension of the wings 4 reduced. Added twice the radial extent of the recesses 16. With such a shaped cam 15 ensures that the wings 4 always rest on the inner circumference 6 of the stator 2 and there ensure adequate sealing.
  • the wings 4 abut with their front side either on the side wall 7 or on the cam 4, so that even there is given a sufficient seal.
  • a seal radially inward results from the interaction of the wings 4 with the guides 5.
  • the vane machine 1 shown there has two cycles per revolution.
  • the result is a minimum distance between the inner periphery 6 of the stator 2 and the rotor 3 at points of the rotor 3, which point upwards and downwards, and a maximum distance at points which point to the left and to the right. Since a "delivery stroke" can always be realized when the maximum distance to the minimum distance decreases, the result in Fig. 2 illustrated embodiments two cycles per revolution. This possibility is provided by the cam 15.
  • FIGS Fig. 1 and 2 show the vane machine 1 in perspective view. Same parts are denoted by the same reference numerals as in FIGS Fig. 1 and 2 Mistake.
  • the cam 15 is formed here as a separate element. However, it may also be formed integrally with the side wall 7.
  • cam 15 If one forms the cam 15 as a separate element, then you can dimension their two faces or pressure application surfaces on the two end faces, which can be defined for example by seals, not shown, so that there is a force balance on the rotor in the axial direction. This allows you to minimize a game and accordingly keep a small leak.
  • the wings 4 have a core of a steel and a coating of a plastic friction-co-operating with steel.
  • the wings 4 are designed so that they can interact with low friction with the stator 2 and the guides 5 in the rotor 3. Also at their end faces, which bear against the side wall 7 formed of steel, results in a reduced friction.
  • plastics it is possible to use, for example, 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, polyethersulfones, polyetherimides, polyamideimides, polyacrylates, phenolic resins such as novolak resins or the like, which may be glass, graphite, polytetrafluoroethylene or plastic, especially in fibrous form, as fillers , When using such materials, water can also be used as hydraulic fluid.
  • polyaryl ether ketones polyether ether ketones
  • the cam 15 should be provided with a corresponding plastic, at least in the area where the rotor 3 rests with its front side.
  • the recesses 6 are expediently milled out of the wings 4 after the plastic has been applied , This results in the contact surface 17, an area which is at least partially formed of a steel and then rests against the plastic of the cam 15. Due to the rounded shape of the contact surface 17 can also be achieved that a contact between the plastic of the wing 4 and the plastic of the cam 15 can be practically avoided.
  • the wing 4 then also has an end face 18, which is formed by the recess 6, which also consists essentially of the steel of the core of the wing 4 exists. This surface 18 then abuts axially on the cam 15, so that a pairing plastic - plastic is avoided and a mating steel - plastic is achieved here.
