Definitions

  • the present invention relates to a method for mounting a crank mechanism, comprising a crankshaft and at least one connecting rod, in a crankcase of a reciprocating compressor. Furthermore, the invention also relates to a reciprocating compressor itself, which is produced by such a method.
  • Reciprocating compressors of the type of interest here are usually coupled to a drive unit - usually an electric motor - to compress air via the rotary motion generated hereby by means of a crank mechanism and an oscillating linear motion piston.
  • the piston compressor formed by the piston compressor with drive unit is used for example in the vehicle sector for the production of compressed air, which is required for the operation of vehicle-specific pressure medium units - such as brakes or the like.
  • the cylinder head contains inlet and outlet valves for sucking in or expelling the compressed air.
  • the crankshaft is mounted so that the preassembled crankshaft with connecting rod can be inserted therein for mounting the crank mechanism, ie for mounting the at least one connecting rod on the crankshaft.
  • crankcase or the connecting rod are designed to be split, a correspondingly high manufacturing outlay is required by milling contact surfaces of the crankcase or the connecting point on the connecting rod end. Furthermore, for the screw corresponding threaded holes to make and additional components, such as gaskets and screws are necessary.
  • the object is achieved on the basis of a method for assembling a crank mechanism according to the preamble of claim 1 in conjunction with its characterizing features.
  • the object is achieved by claim 4.
  • the invention includes the procedural teaching that for assembling a crank mechanism, comprising a crankshaft and at least one connecting rod in a crankcase, the following method steps are carried out:
  • a one-piece connecting rod is inserted through a cylinder opening of the one-piece crankcase, - a crankshaft is inserted through a crankshaft bearing opening of the one-piece crankcase,
  • the crankshaft is threaded with the end located in the interior of the crankcase in an opening of the connecting rod until the connecting rod is in the mounted position relative to the crankshaft and in this case forms a press connection with the connecting rod bearing seat of the crankshaft.
  • the advantage of the solution according to the invention lies in the fact that a division of crankcase and / or connecting rod for mounting the crank mechanism can be completely eliminated.
  • the end of the crankshaft in the opening of the connecting rod in the interior of the crankcase, the cylinder opening and the crankshaft bearing opening are to be dimensioned accordingly.
  • the crankshaft bearing opening is provided for
  • crankshaft bearings Inserting the crankshaft bearings.
  • the need for Einfädelmontage is observed.
  • By saving a split crankcase and / or a split connecting rod piston compressor of the invention takes a total of less space, since less material for threaded holes in the crankcase is required. Incidentally, it does not matter if first the crankshaft through the
  • Crankshaft opening is inserted into the interior of the crankcase or the connecting rod through the cylinder opening.
  • Hub journal bearing is preassembled on the crankshaft or connecting rod before the crankshaft and connecting rod are inserted into the interior of the crankcase.
  • the Hubzapfenlager may be formed as a permanently lubricated roller bearing. A particularly simple assembly results when the Hubzapfenlager is first mounted on the connecting rod, before the connecting rod velvet
  • Hubzapfenlager is mounted on the crankshaft over the bearing inner ring of the Hubzapfenlagers.
  • the other alternative variant may be useful.
  • balance weights - if necessary - are releasably secured to the crankshaft and preferably can be fixed thereto by screwing.
  • the one-piece crankcase is manufactured by prototyping. It can consist of cast iron or aluminum alloys. Through the production by prototyping, in particular casting - and the minimal machining reworking, which is required in view of the solution according to the invention, the crankcase can be produced in a particularly simple manner.
  • FIG. 2 shows a schematic diagram of a method for assembling the crank mechanism at the beginning
  • FIG. 3 shows a schematic diagram of a method for assembling the crank mechanism to the end.
  • the dry-running reciprocating compressor shown in Fig.l consists essentially of an undivided crankcase 1, at the Zylinderöffhung 2, a cylinder 3 is mounted for a here axially guided piston 4.
  • the cylinder 4 is closed by a cylinder head 5.
  • a crankshaft 6 is arranged rotatably mounted within the crankcase 1.
  • the crankshaft 6 acts via a Hubzapfenlager 7 formed in the manner of a permanently lubricated bearing to form a crank mechanism with a one-piece, undivided connecting rod 8 via the connecting rod 9 together.
  • the crankshaft 6 carries dynamic balance weights 10 bolted thereto.
  • the one-piece connecting rod 8 is first introduced through the cylinder opening 2 of the likewise one-piece crankcase 1 for mounting the crank mechanism. Thereafter, the crankshaft 6 is inserted through a crankshaft bearing opening 11 of the crankcase 1 in the interior, that the inner end of the
  • crankshaft 6 within the crankcase 1 in the opening of the connecting rod 9 of the connecting rod 8 can be threaded.
  • the crankshaft 6 is shaped such that the opening of the connecting rod 9, which is already preassembled with the - not shown here - Hupzapfenlager, can thread to the big end bearing seat of the crankshaft 6.
  • the connecting rod 8 is in the fully assembled position relative to the crankshaft 6, wherein the connecting rod 8 via the crank pin bearing with the crankshaft 6 forms a press connection.
  • This press connection is realized by appropriate fit dimensions of the components to be connected.
  • the connecting rod 8 can be heated so that it expands temporarily; Furthermore, the crankshaft 6 can also be cooled, so that the material contracts slightly during assembly.

Abstract

L'invention concerne un procédé pour le montage d'un embiellage, comprenant un vilebrequin (6) et au moins une bielle (8) présentant une tête de bielle (9) côté vilebrequin, dans un carter de vilebrequin (1) d'un compresseur à piston. Le procédé selon l'invention comprend les étapes suivantes : introduction d'une bielle monobloc (8) à travers un orifice de cylindre (2) du carter de vilebrequin monobloc (1) ; introduction d'un vilebrequin (6) à travers un orifice de palier de vilebrequin (11) du carter de vilebrequin monobloc (1) ; enfilage du vilebrequin (6), par l'extrémité se trouvant à l'intérieur du carter de vilebrequin (1), dans un orifice de la tête de bielle (9) jusqu'à ce que la bielle (8) se trouve dans la position montée par rapport au vilebrequin (6) et forme ainsi une liaison par emmanchement avec le siège de palier de bielle du vilebrequin (6).
