Definitions

  • the invention relates to a machine housing, in particular a cylinder head for an internal combustion engine, with the features of the preamble of patent claim 1.
  • Object of the present invention is to show a simplified lubricant supply for the bearings of a generic machine housing.
  • the machine housing has a wall that emerges in the installed position of the machine housing from a bearing and / or spilled lubricant in the machine housing, wherein another bearing is at least partially disposed in the collected lubricant.
  • the manufacturing costs for a generic machine housing are reduced because the processing of lubricant holes or the use of additional lubricant spray nozzles deleted.
  • the machine housing according to the invention has a reduced lubricant delivery requirement, whereby a smaller lubricant pump can be used. This also leads to lower production costs, and to a reduced fuel consumption of the internal combustion engine.
  • the embodiment of the invention is suitable in particular for largely parallel to the camshaft arranged waves according to claim 2.
  • the water emerging from the bearing of the camshaft lubricant can be collected in the geodetically lower trough.
  • a part of the lubricant splashed during operation of the internal combustion engine, for example, by the cam of the camshaft in the trough is collected.
  • the proposed embodiment is particularly suitable for variable stroke valve trains with a stroke height adjustment by an eccentric shaft.
  • Fig. 1 shows the top view of a three-dimensionally illustrated engine housing 1 with a camshaft 2, in the present case, a cylinder head for an internal combustion engine.
  • the view is directed to a dividing plane 1 'of a recognizable in Fig. 2 bearing 3 another shaft 4.
  • the further shaft 4 has on its outer circumference a gear segment 4 'with an outer toothing 4 ".
  • This gear segment 4' serves to rotate the further shaft 4 during operation of the internal combustion engine, in the present embodiment an eccentric shaft, by means of a worm wheel (not shown) 4 'is arranged in sections in a geodetically deeper depression 6 and protrudes into a lubricant collected in the depression 6.
  • the depression 6 is formed by three outer walls 1 "of the machine housing 1 and a wall 5 which according to the invention is oriented largely vertically in the installed position in the embodiment between two outer walls 1 "extends, represented by a double arrow ..
  • a part of the bearing 3 is arranged in the collected in the trough 6 lubricant.
  • the depression 6 in the present embodiment is filled up with lubricant sprayed by the valve drive and lubricant injection nozzles.
  • a further bearing can be arranged geodetically above the trough 6, in which case the trough 6 is additionally filled with lubricating lubricant exiting from this bearing and, depending on the structural design.
  • the further shaft 4 as already briefly noted above, an eccentric shaft for a variable-stroke valve drive, wherein the further shaft 4 is arranged parallel to the camshaft 2.
  • the wall 5 may also be cup-shaped, free-standing formed on a bottom surface of the machine housing 1, without having a direct contact with the side walls 1 '.
  • the trough 6 is formed only by the wall 5 and the bottom surface of the machine housing.
  • Fig. 2 shows the same structure of Fig. 1, but without camshaft 2 and without further shaft 4. For the same components apply the same reference numerals.
  • the manufacturing or manufacturing costs for a generic machine housing are reduced, since no lubricant bores or separate lubricant spray nozzles are necessary for the bearing 3 and / or the external teeth 4 "
  • the energy requirement of a smaller lubricant pump is lower, which reduces fuel consumption is reduced during operation of the internal combustion engine.
