Definitions

  • the invention relates to a radial piston compressor with a cylinder block rotatably mounted on a fixed axis, which has at least two piston chambers, in each of which a radially reciprocable piston is arranged, in which compressor the radial movement of the pistons by a guide ring arranged eccentrically to the axis of rotation of the cylinder block is controlled, on which the pistons are supported directly or via an intermediate part.
  • Such a compressor is known from DE-OS 31 20 812.
  • the pistons are supported on the guide ring by balls.
  • the guide ring is rotatably arranged, there is nevertheless a relative movement between the balls and the guide ring, which causes the guide ring to wear and fatigue accordingly.
  • the invention has for its object to develop a radial piston compressor of the type described above so that the life of the guide ring can be increased despite the wear and fatigue of the guide ring.
  • the object is achieved according to the invention in that the support points of the pistons or the intermediate parts on the guide ring lie on axially offset circumferential planes. Such an axial offset distributes the stress to different locations on the guide ring, so that the guide ring can be operated for a longer period of time without causing malfunctions due to wear and fatigue.
  • the axial offset of the support points is achieved in a particularly simple manner in that the piston spaces within the cylinder block are axially offset from one another.
  • the axial displacement of the piston chambers also ensures that the support forces always act vertically on the guide ring and thus no transverse components occur.
  • a further increase in the service life of radial piston compressors, in which the pistons are supported on the guide ring by balls, is possible in that several guide grooves are provided on the guide ring which are axially offset according to the axial displacement of the piston chambers. With such guide grooves, the osculation between the balls and the guide ring is improved and the load is thereby distributed over a larger area.
  • a cylinder block 2 is rotatably arranged on a fixed axis 1.
  • the cylinder block 2 has a plurality of cylindrical piston spaces 3 distributed uniformly over its circumference.
  • a freely movable piston 4 is arranged in each piston chamber 3 and is supported in each case on a guide ring 6 via a ball 5.
  • the guide ring 6 is in turn on a bell-shaped Carrying part 7 attached, which is rotatably mounted on an axis piece 8 offset on one side relative to the axis 1.
  • Arms 9 connected to the cylinder block 2 couple it to a drive motor.
  • the pistons 4 are moved back and forth in the piston chambers 3.
  • the medium to be compressed is sucked in via a suction line 10 formed in the axis extension 8 and in the axis 1 and is ejected via a pressure line 11 likewise formed in the axis extension 8 and in the axis 1.
  • the two piston spaces 3 shown in the drawing are axially offset from one another by the distance A.
  • the support points 12 and 13 of the two balls 5 on the guide ring 6 lie on different axially offset rotational levels.
  • the distance A is chosen so large that the deformation or stress fields of the individual raceways resulting from the pressure of the balls only touch or overlap with their weaker edge zones. This is the case when the distance A is about 4 to 10 of the ball diameter.
  • the tread 14 of the guide ring 6 is formed in a groove shape.
  • the balls 5 are thus with a larger area on the guide ring 6, so that this reduces the specific pressing forces.
  • the balls 5 rotating in each plane can also be assigned a separate guide groove.
