Definitions

  • the invention relates to a fastening arrangement for Cover on machines in the preamble of the claim 1 explained Art.
  • connection between two housing parts known by a rubber-elastic profile strip against the transmission of structure-borne noise from one the other housing part is insulated.
  • the rubber-elastic profile strip includes an outward facing Edge of one housing part and lies in a recess of the other housing part, where it is sealed by a holding plate is tensioned.
  • the known connection has the disadvantage that at least a housing part encircling recesses for receiving of the profile strip must be provided and that at the First assemble the profile strip onto the edge of the placed on a housing part and only then in the recess must be introduced.
  • From DE-PS 40 01 470 is an internal combustion engine with one Oil-repellent part known, with a circumferential flange a vulcanized sealant made of elastic material is provided, which is both on the top and on extends the underside of the flange and at least in certain areas extends through openings in the flange.
  • the object of the invention is a fastening arrangement for lids on machines, which is in the preamble of the claim 1 explained type to create, with little construction easy assembly and safe decoupling ensures against the transmission of structure-borne noise.
  • this object is achieved by a fastening arrangement for covers on machines in the generic term of claim 1 explained type in the characterizing part of claim 1 features shown.
  • a circumferential sealing surface 2 is on a machine component 1 plan processed and has a variety of e.g. Tapped holes 3 for receiving fastening bolts 4.
  • a cover 5 for the machine in the present embodiment a valve cover of an internal combustion engine is e.g. manufactured as a pressed sheet metal part or as an aluminum casting and must on the machine component 1, in the present case the cylinder head the internal combustion engine, against a transmission of Structure-borne noise can be decoupled and sealed.
  • the cover 5 is provided with a circumferential flange 6, which in certain areas with extensions 7 for inclusion the fastening bolt 4 is provided.
  • the flange 6 is in the area of the extensions 7 with through openings 8 provided.
  • the flange 6 of the lid 5 is on its sealing side 9 and its fastening side 10 with a vulcanized rubber-elastic Provided profile strip 11, which on the Sealing side 9 of the cover 5 as a circumferential, with sealing ribs 12 provided seal extends while on the mounting side 10 formed as supports 13 only in partial areas is that of clamping pieces 14, 15 and 16 by means of Fastening bolts 4 are clamped.
  • the pads 13 and the clamping pieces 14, 15 and 16 are here the extended areas 7 with corresponding bulges 17, 18 and 19 adapted and extend over a such area dimension, that by means of the two provided or the one fastening bolt 4 a bracing of the Lid 5 allows with a corresponding biasing force which ensures a secure seal.
  • the fastening bolts 4 are known per se Way as fastening screws with collar or as fastening screws with collar and sleeve.
  • the rubbery one Profile strip 11 occurs in the area of passage openings 8 in the flange 6 for the fastening bolts 4 of the Sealing side 9 of the flange 6 of the cover 5 to the fastening side 10 through and shields them as collar bolts Spacer sleeves trained mounting bolt 4 against physical contact with the lid 5.
  • the clamping pieces 15 and 16 are at least compared to their bulges 18 and 19 with bevels 20 and 21 provided and the upper supports 13 are executed so that they are one in Fig. 3 in dash-dot lines have indicated bead 22 which the clamping pieces 15 and 16 against twisting and come to rest on the lid 5 supports.
  • fastening bolts 4 instead of using fastening bolts 4 also an attachment of the lid by itself known C-shaped spring clips or by knee lever or the like possible.
