Definitions

  • the invention relates to a vacuum pump with a wing, a pump housing and a rotor rotatably mounted therein, wherein the wing has a constant length and is slidably mounted in the rotor and the wing tips on both sides protrude radially from the rotor and abut the inner peripheral surface of the pump housing, whereby the Wing defines a suction chamber and a pressure chamber.
  • a vacuum pump which has a pump housing in which a rotor is arranged.
  • This rotor supports a wing, which rests against the inner peripheral side of the housing.
  • the wing is constructed in two parts, so that it can take different lengths. This ensures that the wing always rests against the inner peripheral surface and divides the pump room into a pressure chamber and a suction chamber.
  • the wing tips are provided with inserts, which consist of a hard material.
  • inserts consist of a hard material.
  • the invention has for its object to provide a vacuum pump in which the wear is minimal.
  • the housing of the vacuum pump is made of steel, which has the advantage that the housing can absorb high forces and yet is easy to work.
  • the wing is made of a metal which is harder than the housing of the vacuum pump, in particular harder than the inner peripheral surface of the pump housing.
  • the wing is for example titanium or a titanium alloy, steel, stainless steel, aluminum or brass.
  • Optimal pressure forces of the wing on the inner peripheral wall are achieved by the fact that the wing is flattened in the region of its wing tip on the pressure side, wherein the flattening is at an angle to the longitudinal axis of the wing.
  • the inner peripheral surface of the pump chamber is a circular cylindrical surface.
  • the sash then makes a sinusoidal reciprocation within the slot of the rotor.
  • the distribution of forces or the load changes the tip of the wing is then continuous and not abrupt.
  • recesses or openings are provided parallel to the wing tip and the wing is slightly more elastic due to the recesses or the openings in the longitudinal direction.
  • the wing can adapt to a heat-related expanding pressure chamber, so that the tightness is still guaranteed both in cold and in hot vacuum pumps.
  • 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 22 slidably.
  • the wing 20 has a constant length, which is matched to the inner diameter of the housing 12.
  • the rotor 18 passes through the housing 12, in particular a bottom 26 of the interior 18, and protrudes with a non-illustrated portion on the back of the housing 12, over which it is rotated (by means of a drive, not shown) in rotation.
  • the interior 16 is delimited by a substantially circular cylindrical inner circumferential surface 32, against which the tips 34 of the wing 20, which divide the interior into a suction chamber 54 and a pressure chamber 56, since the outer peripheral surface 44 of the rotor 18 permanently abuts against the inner peripheral surface 32.
  • the wing tips 34 have a flattened side 30 and a rounded side 36.
  • the flattened side 30 is located on the pressure side, which means that the wing 20 shown in FIG. 1 rotates in the direction of the clockwise direction.
