Definitions
- the invention relates to a single-wing vacuum pump with a cup-shaped housing, a rotor rotatably mounted eccentrically in the housing, a rotatably mounted in the rotor orthogonal to the axis of rotation and a wings receiving working space with an inner peripheral surface, against which the two opposite sealing edges of the wing, wherein the Wing divided the working space into a suction chamber and a pressure chamber.
- Vacuum pumps with such a structure are known (DE 100 46 697 Al). As a rule, they serve to provide a vacuum for a vacuum consumer, for example in a motor vehicle, by causing the rotor to rotate and sucking air out of a vacuum line via the suction space.
- the working space of this vane pump is designed so that the wing with its two opposite ends on the inner circumferential surface slides along. The wing separates the suction chamber, which is connected to the suction port, from the pressure chamber, which is connected to the pressure port. In order to achieve high efficiency, the wing must be permanently attached to the inner peripheral surface, since the suction chamber is otherwise ventilated.
- a known solution proposes to build the wing in two parts and to insert a spring between the two wing parts, which urges the two wing parts outward in the direction of the circumferential surface. This will ensures that the sealing edges of the wing are permanently attached to the inner circumferential surface.
- a disadvantage is considered that this wing is subject to considerable wear due to the contact pressure, which not only reduces the efficiency, but also maintenance intervals are shortened.
- a vane pump has become known in which a plurality of blades are arranged eccentrically in the rotor. The wings are acted upon at their wing tip and the wing bottom with the pressure prevailing in the pressure chamber.
- a lubricating device for fast-running rotary body is known in which the lubricating film distributing wing is chamfered on its front.
- the invention is therefore based on the object to provide a single-wing vacuum pump, which has a better efficiency.
- the ends of the wing are rounded in a cylindrical shape and lie on a central contact or surface line of the cylinder on the inner peripheral surface of the working space.
- the end of the wing is partially flattened on the pressure side, whereby the pressure forces acting on the wing are changed in their direction.
- the flattened section increases the radial component of the compressive force which counteracts the centrifugal force of the wing.
- the centrifugal force of the wing which the wing to the circumferential surface presses the working space, so is reduced by the opposing pressure force from the pressure chamber. The wing is thus pressed less strongly to the Uinfangs realization.
- the flattened portion is planar.
- Such trained wing tips are relatively easy to produce, since this flattened portion, for example, attached by a milling process, can be produced.
- the section has a deviating from 0 ° angle to the longitudinal surface of the wing.
- the wing is located off-center on the inner peripheral surface.
- the contact line thus has a distance to the median plane of the wing, whereby the advantage is achieved that the flattened portion can be made larger. As a result, the tangential component of the compressive force can be further reduced.
- the surfaces bounding the portion or adjacent to the portion are partially cylindrical. This provides the advantage that the contact line can relatively easily move along the surface of the wing tip. Since the angle of attack of the wing during a complete revolution of the rotor changes permanently, and the contact line of the wing tip migrates slightly, the cylindrical design of the wing tip ensures uniform wear.
- a harmonious course and thus a simple production of the wing tip is achieved in that the surfaces on the wing tip steadily pass into the flattened section.
- the surfaces and the section at the transition points can have the same tangents exhibit.
- the processing tools can produce the wing tip in a single operation or can be easily and inexpensively manufactured in an injection-molded wing tip injection mold.
- the wing has a wing body and two terminal attachments. At these essays, the flattened portion is formed and these essays are applied to the inner circumferential surface of the working space.
- This has the significant advantage that worn wings can be maintained by replacing the attachments, which attachments may preferably be made of plastic, whereas the wing body is made of metal, for example.
- the wing body is a die-cast or injection-molded element and the attachments are injection-molded.
- the wing body at its the tips receiving ends each have a slot which is orthogonal to the longitudinal broad side of the wing body.
- the article has a U-shaped or C-shaped cross-section formed by two parallel legs.
- the legs flank a ridge, wherein the legs are formed semicircular even at its free end and engage in a corresponding semi-circular Auf founded at the ends of the wing body.
- Both the bridge and leg support prevent the attachments from making undefined movements during operation of the pump. In particular, a flutter or rattle is prevented In addition, noise developments are prevented.
- the essays are pushed under low bias on the ends of the wing body.
- Figure 1 is an exploded view of the vacuum pump
- Figure 2 is a perspective view of
- Figure 3 is a perspective view of a wing body
- Figure 4 is a perspective view of an essay
- FIG. 5 is a plan view of one end of the wing, showing the pressure distribution.
- a vacuum pump in which the housing 12 is shown without housing cover.
- the housing 12 has a suction port 14, which opens into an interior 16.
- a generally designated 18 rotor in which a wing 20 is mounted orthogonal to the axis of rotation 21 slidably.
- the wing 20 divides the working chamber 22 formed by the interior 18 into a suction space 24 and a pressure space 26.
- the wing 20 rests with its two ends 28 against an inner peripheral surface 30 surrounding the working space 22.
- the wing 20 is formed by a wing body 32 and two attachments 34.
- FIG. 3 shows the wing body 32, wherein FIG. 4 shows one of the attachments 34.
- the wing body 32 is made of metal in the embodiment and is a die-cast part, but it may also be injection-molded.
- the article 34 is made of plastic and is injection molded.
- cavities 36 which are designed either continuously or as a blind hole.
- the wing body 32 each have a slot 40 which extends on the one hand in the direction of the longitudinal axis 42 of the wing 20, on the other hand orthogonal to the broad side surface 44.
- the longitudinal axis 42 of the wing 20 is located between the two broad side surfaces 44 and the contact line 68 is located between the longitudinal center plane 70 and the suction side 42 facing broad side surface 44th
- the two broad side surfaces 44 are provided in the region of the ends 38 with substantially semicircular recesses 46, in which leg 48 (see Figure 4) of the Attachment 34 can be inserted.
- the two legs 48 flank a web 50, which also extends in the direction of the longitudinal axis 42 of the wing 20 and has the shape of the slot 40. Both the slot 40 with web 50 and the recess 4 ⁇ prevent the attachment 34 can be displaced in the direction of the axis 52.
- the legs 48 engaging around the end 38 prevent the attachment 34 from dodging in the direction of the axis 54. This means that the attachment 34 is fastened on the wing body 32 so as to be displaceable only in the direction of the longitudinal axis 42.
- FIG. 5 shows a plan view of the wing body 32 with attached attachment 34.
- the attachment 34 touches the inner peripheral surface 30, so that the suction chamber 24 are below and the pressure chamber 26 above the wing 20.
- the vane 20 rotates in the direction of the arrow 56 and, at its rear side facing the suction space 24, merges into the broad side surface 44 of the wing 20 at an angle different from the 90 °.
- the attachment 34 has a flattened section 66 on which the pressure force 60 acts.
- This pressure force 60 is composed of the pressure force 58 and an additional pressure force 62, which arises because the contact line 68 has a distance A from the center plane 70 of the wing 20. Since the pressure force 60 actually acting on the wing 20 due to the displacement of the contact line 68 is greater than the pressure force 58 in a conventional wing, and also the negative pressure in the suction chamber 24th originating forces 74 are smaller than in a conventional wing, the contact pressure at the contact line 68 is substantially reduced, whereby the wear is reduced.
- the contact line 38 is located on a partially cylindrical portion 72 of the attachment 34.
- the partially cylindrical portion 72 is continuous with the same tangent in the flat portion 66 on. This provides the advantage that lubricating oil located on the pressure side of the blade 20 is evenly distributed over the portion 66 and then evenly over the portion 72, so that the contact line 68 is wetted over its entire length.
