Definitions

  • the invention relates to an internal-axis rotary lobe machine according to the preamble of patent claim 1.
  • a machine of this type is known for example from DE-HA-34 32 915. It is comparable to the arrangement of a hollow gear and a pinion arranged in it.
  • the parts of the external rotor are usually relatively thin-walled in addition to its control openings in the radial direction and can therefore be bent out by the pressure of the working medium and in particular by centrifugal forces.
  • the entire engaging parts of the external rotor especially when the machine is elongated, are subjected to bending forces.
  • the diameter of the outer rotor can be increased. However, this also leads to an increase in the harmful spaces present in the control openings.
  • the outer rotor diameter is therefore not increased overall, but rather only by ring-like webs which connect the engagement parts of the outer rotor to one another and which are preferably narrow, i.e. like an annular disc.
  • the inside diameter of the Housing shell are brought up to the unexpanded outer diameter of the outer rotor, so that no additional harmful spaces are created.
  • the stiffening web or webs bring about a small reduction in the control cross sections of the external rotor, very high rotational speeds and any axial extension of the rotary piston machine are possible due to the invention.
  • the at least one stiffening web can be an integral part of the outer rotor or can consist of a ring which is freely placed, for example shrunk on.
  • the latter is either designed in a split manner or sleeve-shaped filler pieces are inserted axially into the spaces on both sides of the stiffening web and between the circumference of the outer rotor and the housing shell.
