Definitions

  • the invention relates to a compressor assembly consisting of a radial piston compressor and a drive motor, in which the rotor of the drive motor is connected to the cylinder block of the radial piston compressor and is guided radially by the latter.
  • Such an assembly is known from DE-PS 27 10 734.
  • the cylinder block is rigidly connected to the runner's arms.
  • the rotor does not have its own axle bearing on this side, but is guided radially by the cylinder block.
  • misalignments occur between the rotor of the engine and the cylinder block.
  • Such misalignments lead to a tilting of the cylinder block when the cylinder block is rigidly connected to the arms of the rotor.
  • the bearings of the cylinder block are loaded unevenly.
  • the invention has for its object to provide a compressor assembly consisting of a radial piston compressor and a drive motor so that on the one hand tilting of the cylinder block due to misalignment between the rotor of the drive motor and the cylinder block avoided, but on the other hand the radial guidance of the motor rotor through the cylinder block is guaranteed.
  • the object is achieved according to the invention in that the rotor and the cylinder block are connected to one another via a cardan joint. Radial forces, such as the magnetic pull of the rotor transverse to the axis, and its torque can be practically rigid via such a joint be transmitted. However, it allows misalignment between the cylinder block and the rotor of the drive motor due to misalignment.
  • a structurally particularly simple embodiment of the clutch arrangement is obtained according to a further embodiment of the invention in that leaf springs are provided as a cardan joint approximately in the central plane of the cylinder block, with one end of the cylinder block and the other end of projections or arms of the Runners are attached, wherein one of the ends of the leaf springs is fixed against rotation.
  • leaf springs are very stiff in the radial and tangential directions, but relatively soft in the axial direction, so that they allow a misalignment between the coupled parts without any further.
  • the rigidity in the radial and tangential direction can be increased further in that the leaf springs are V-shaped and the one leg of each leaf spring is fastened at two spaced apart locations.
  • a cylinder block 2 1 with a fixed axis is designated, on which a cylinder block 2 is rotatably mounted.
  • the inner stand 3 of a drive motor designed as an external rotor motor is also arranged on the fixed axis 1.
  • the outer rotor 4 of the drive motor has axially projecting arms 5. Its lower end is radially and axially by a roller bearing, its upper end radially by the coupling the cylinder block 2 out. This ensures an even engine air gap.
  • V-shaped leaf springs 6 The coupling between the arms 5 and the cylinder block 2 takes place via V-shaped leaf springs 6.
  • the leaf springs 6 are stacked in several layers.
  • the leaf springs 6 are fastened to the cylinder block 2 at two spaced locations 7 and 8. These attachment points are located approximately in the central plane of the cylinder block 2.
  • the leaf springs 6 With their other leg, the leaf springs 6 are connected to the arms 5 of the external rotor 4.
  • they become very rigid in the radial and tangential directions, so that they can transmit high forces in these directions without the leaf springs 6 being deflected or displaced. A separate storage of this side of the motor rotor 4 on the axis 1 is therefore unnecessary.
  • connection of the outer rotor 4 to the cylinder block 2 is relatively soft, in particular in the case of a multilayer arrangement of the leaf springs 6, so that the cylinder block 2 can adjust itself accordingly to the outer rotor 4 in the event of misalignments without the engine air gap being changed.
  • Such a coupling arrangement is particularly advantageous if, when the cylinder block 2 is mounted directly on the fixed axis 1, the gap between the cylinder block 2 and the fixed axis 1 has a decreasing cross-section in the direction from the suction slot to the pressure slot, to one from the suction slot Pressure slot to receive increasing oil pressure in the gap in accordance with the compression pressure. Due to the elasticity of the leaf springs 6 in the axial direction, the cylinder block 2 can always adjust so that ke . occurs in tilting of the cylinder block with respect to the fixed axis 1. Such tilting would result in an uneven gap in the axial direction which could not be adequately sealed by the oil introduced.
