Definitions

  • the invention relates to a disc separator for the purification of gases, in particular blow-by gases of the crankcase ventilation of motor vehicles with an upper housing part and a lower housing part.
  • Plate separators are in the truck sector as Feinölabscheider in series.
  • the blow-by gas with fine droplets of oil passes through the rotor equipped with rotating conical plates in the disk separator. This rotates at up to 10,000 revs / min.
  • the oil droplets are thrown against the underside of the plates and separated due to the centrifugal forces occurring.
  • the purified blow-by gas is discharged via a blow-by output and fed back to the engine intake.
  • the separated oil is returned to the engine via an oil drain line.
  • the rotors of such a plate separator are usually driven by an electric motor or an oil turbine. These rotors are usually used in machined aluminum housings, which are closed by cover and bottom lid.
  • the aluminum housing are expensive to edit. Housing, rotor holder and cover are usually assembled and screwed together with gaskets.
  • the heavy aluminum housing is able to absorb the shrinkage and thus to dampen the noise. With imbalances this can lead to vibrations. Therefore, a rigid construction of the housing is important. A vibration insulation by mass is undesirable when installed in a car.
  • a Tellerseparator for the purification of gases, in particular blow-by gases of the crankcase ventilation of motor vehicles with an upper housing part 1 and a lower housing part 2, which is characterized in that the upper housing part lund the lower housing part 2 each comprises a plastic material, in particular.
  • the weight of the plate separator according to the invention can be significantly reduced if a plastic, in particular a fiber-reinforced, particularly preferably a glass fiber and / or a carbon fiber reinforced polyamide is used as the material for the upper housing part 1 and / or the lower housing part 2.
  • a plastic in particular a fiber-reinforced, particularly preferably a glass fiber and / or a carbon fiber reinforced polyamide is used as the material for the upper housing part 1 and / or the lower housing part 2.
  • the plastic material has only about 50% of the density of the aluminum, it is recommended that the housing upper and lower shell made of plastic, preferably made of glass fiber reinforced polyamide and thus save considerable weight.
  • the modulus of elasticity of the plastic material at about 10,000 N / mm 2 is significantly lower than that of aluminum at 70,000 N / mm 2 . Therefore Structural modification makes structural stiffening meaningful in order to obtain a solid component that withstands vibration excitations.
  • the upper housing part 1 and the lower housing part 2 of the TellerseparatorgePFuses be welded to the adjacent plastic components.
  • two shells 1.2 closed hollow body can arise, which achieve a much greater rigidity than sprayed individual shells.
  • the upper housing part 1 and / or the lower housing part 2 are welded to the adjacent flange 3, as shown in Fig. 1.
  • Fig. 1 also shows the plate separator according to the invention with the essential properties.
  • the upper housing part 1 is welded to the lower housing part 2.
  • the rotor 5 is located in the rotor bearing 6, which is integrated in the rotor carrier 4.
  • the flange 3 is welded to the lower housing part 4 here.
  • the drive paddle wheel 8 and the plate 9 of the plate separator can be seen.
  • the plate separator is connected via the flange 3 to the engine block 7.
  • a further stiffening results from welding the rotor carrier 4 into the housing lower part 2, as shown in FIG.
  • the various welding levels are shown.
  • the weld between the flange 3 and the lower housing part 2 is shown.
  • the welding of the housing lower part 2 with the rotor support 4 carries the reference numeral 11, while the welding of the housing upper part 1 is provided with the housing lower part by the reference numeral 12. If the upper housing part 1, the lower part lgesch dip, we obtain a one-piece housing with a closed bearing surface.
  • the rotor axis 5 is mounted in a preferred manner with ball bearings in the rotor carrier 4 made of plastic. It is possible to inject a ball bearing directly into the rotor carrier 4 and press the second, especially if the rotor carrier 4 is also made of the same plastic material.
  • Another possibility is to inject a metal sleeve 13 into the plastic rotor carrier 4 and to mount both rotor bearings in this sleeve 13.
  • This designed as a cantilever rotor bearing has the advantage that the rotor 5 has no direct contact with the outer housing and thus vibrations from the rotor 5 are not passed directly.
  • a further advantageous embodiment is to encase a steel bushing 14 for the bearing support, for example with an elastomer, and to insert it into the rotor support 4 in order thereby to decouple the rotor bearing from the housing.
  • This embodimentm is shown in FIG. 5 is shown.
  • housing seal Another advantage of the housing seal is that no elastomer seals between the housing parts are needed to the to seal the oil-carrying disc separator to the environment. The same applies to inner seals of the rotor support 4 to the housing. Again, oil spaces must be separated from each other tightly. The weld is oil-tight, a seal is no longer required.
  • the component according to the invention can be bolted as a closed structural body directly to the engine and can thus use the mass of the engine block as a fixed bearing.
  • the vibration amplitudes and deformations are greatly reduced by the stiffness of the welded housing structure.
  • a one-piece housing is obtained by welding, which carries the rotor bearing 6 in its interior.
  • the welded plastic housing design makes it possible to produce a light plate separator with a weight of less than 500 g. This can be flanged directly to the engine. Welded oil and gas transport channels can be integrated. Due to the rigid welded housing, the disk separator is firmly bolted to the heavy engine block, wherein the rotating rotor 5 is mounted inside the housing.
