Definitions

  • radial seals are used as seals on rotating shafts. These radial sealing rings are provided with a sealing lip that rests on the shaft surface. The sealing lip is pulled onto the shaft surface by means of a spiral ring and a seal is achieved.
  • the sealing ability of these radial sealing rings depends on the circumferential speed of the shaft, which means that these sealing rings are only of limited suitability for high speeds. If, in addition to the rotation of the shaft, there is also an oscillating movement, considerable difficulties arise during sealing, so that only up to approx. 4 m / sec. a seal comes about.
  • a ball bearing 3 is pushed onto a collar 2 of the friction pin 1, which is supported on the one hand on a retaining ring 4 and on the other hand on a support ring 5.
  • the ball bearing 3 is closed to the grater side by a grease seal 6.
  • the ball bearing 3 is pressed with its outer ring into a guide housing 7 which is guided in the axial direction by means of a wedge 8 in a guide bar 9 and secured against rotation.
  • a radial sealing ring 10 is pressed, the sealing lip 11 of which acts on the actual journal 12.
  • an oil retaining ring 13 is also provided, which is also pressed into the guide housing 7.
  • a splash ring 14 is arranged as seen towards the center of the machine. This spray ring 14 does not rotate, so that the oil which is also conveyed by the friction pin during the oscillating friction movement and which sprays off the shaft at higher speeds is collected by this spray ring 14.
  • the bore 15 in the splash ring 14, through which the friction pin 1 leads, is slightly larger in diameter than the friction pin. The oil still penetrating through this gap reaches the sealing lip 11 of the radial sealing ring 10, which is connected to the friction device as described above.
  • this radial sealing ring does not rotate, but changes due to the construction together with the friction device, the sealing lip is always in the same place on the friction pin, so that the advantage arises that the sealing lip only has to seal in the radial direction and not in the axial direction . This ensures that a seal of the grater against oil leakage is achieved even at higher engine speeds by means of a conventional sealing system.
