Definitions

  • FIG? INTERNAL COMBUSTION ENGINE WITH SOUND-PROOF V-BELT PULLEY
  • the invention relates to an internal combustion engine comprising a vee-belt pulley in a sound-proof sheathing arranged in front of the crank wheel cover.
  • the sound-absorbing sheathing of the vee-belt pulley comprises a sheathing member elastically attached to the crank wheel cover in a sound-proof manner and partly embracing same and a cover removably attached to the sheathing member and located in front of the vee-belt pulley, both the sheathing member and the cover presenting sound-absorbing inserts at the passages of the vee-belt(s), said inserts combining to form an absorption-type silencer closely encompassing the vee-belts.
  • the sound-projection from the belt apertures of the sheathing of the vee-belt pulley is reduced to the minimum so that the acoustic effect of the sheathing is in no way impaired by the presence of belt apertures.
  • the low production costs, long service life and convenient accessibility of the vee-belt(s) deserve also mentioning.
  • FIG. 1 shows a partially vertical cross-sectional view of an internal combustion engine according to the invention
  • FIG. 2 shows a front-end view of the internal combustion engine according to FIG. 1.
  • a sleeve-like intermediate piece 3 is attached by means of bolts 2 and extends through the crank wheel cover 4 of the engine and comprises a fixing flange 5 to which the vee-belt pulley 6 for the drive of the cooling air blower 7 and the generator 8 is attached by means of bolts 9.
  • the vee-belt pulley 6 is located inside a sound-proof sheathing 10 consisting of a sheathing member 11 elastically and sound-proofingly adjoining the crank wheel cover 4 and a cover 12 attached thereto by means of rapid-locking devices 13 in such a manner as to be readily removable.
  • both the sheathing member 11 and the cover 12 are provided with sound-absorbing inserts 16, each of which is combined with the other to form an absorption-type silencer closely encompassing the vee-belt 15. Therefore, only a narrow gap is left at the passages 14 between the vee-belt 15 and the soundabsorbing inserts 16, as a result of which the projection of sound at these passages is considerably reduced.
  • An internal combustion engine having a crankshaft, a crank wheel and further comprising a vee-belt pulley arranged in front of the crank wheel cover and non-rotatably connected with the crankshaft, a soundproofing sheathing encompassing said vee-belt pulley and consisting of a sheathing member elastically attached to said crank wheel cover so as to provide sound-proof sealing and partly embracing said vee-belt pulley, and a cover located in front of the vee-belt pulley and removably attached to said sheathing member, vee-belts extending through said sound-proof sheathing at two passages, sound-absorbing inserts being provided on said sheathing member and said cover at the passages of the vee-belt, said sound-absorbing inserts combining at each passage to provide an absorptiontype silencer closely encompassing the vee-belt.
