Definitions

  • the invention relates to a reciprocating piston engine, in particular an internal combustion engine with a V-shaped arrangement of the cylinders or rows of cylinders, with transverse screws between the engine block and the main bearing brackets attached to the engine block with main bearing high screws in the region of an apron of the engine block for lateral support of the main bearing bracket, and with an oil pan.
  • transverse screw connection of which is carried out at an angle of approximately 90 ° in the direction of the main bearing screw connection, see e.g. DE-OS 35 42 135.
  • the use of transverse screws allows good lateral support of the bearing forces, but due to the rigid connection to the apron of the engine block, increased vibration is introduced into the engine housing, since the noise excitation occurs primarily via the piston connecting rod - crankshaft - Main bearing - apron is made. In particular, all vibrations of the main bearing walls or brackets are transmitted almost undamped due to the rigid lateral integration in the skirt.
  • the object of the invention is to avoid these disadvantages, and to provide a reciprocating machine in which the result of Using the transverse screw connection, increased vibration excitation of the apron and the co-excitation of the oil pan can be avoided.
  • the engine block in the area of the main bearings on both sides of the longitudinal plane pointing in the direction of the engine vertical axis within the skirt in the direction of the oil pan has extensions of the main bearing wall, between which the main bearing brackets are attached and of which in the main bearing brackets seated transverse screws are interspersed, and that the skirt is arranged in a serving to form an exemption between the transverse screws and the inside of the skirt from the extensions of the main bearing wall.
  • the engine block is preferably designed in such a way that the apron covers the bores of the transverse screws and openings are provided in the apron for operating the transverse screws, which openings can be sealed oil-tight against oil leakage with sealing caps or locking screws or the like.
  • a lead frame is arranged between the skirt of the engine block and the oil pan for additional stiffening of the skirt.
  • the apron ends above the holes in the cross screws and is extended by a removable part over the holes in the cross screws.
  • the removable part is the oil pan, the walls of which are extended like an apron in the direction of the engine vertical axis.
  • the removable part is a ladder frame designed like an apron in the direction of the engine vertical axis, which is provided between the apron of the engine block and the oil pan.
  • the internal combustion engine comprises an engine block 1, in the engine block 1 reciprocating piston 2, a rotating in the main bearings 3 crankshaft 4, between the piston 2 and crankshaft 4 the connecting rod 5 transmitting the cylinder pressure forces, the Main bearing 3 supporting main bearing bracket 6, the main bearing high screws 7 for absorbing the bearing forces in the direction of high screwing Z, the transverse screws 8 for absorbing the inclined bearing forces and the oil pan 10 mounted on the apron 9. Furthermore, between the transverse screws 8 and the inside 9 'of the apron 9 the exemptions 12 are drawn.
  • the vibration isolation is particularly effective in combination with a lead frame 14 shown in FIGS. 3 and 4, screwed between the apron 9 and the oil pan 10, with cross bars 14a like rungs and rungs under the main bearing brackets 6 between the lead bars 14b running in the longitudinal direction of the engine.
  • FIG. 5 and 6 show an embodiment with a shortened apron 9 ending above the bores of the transverse screws 8; After dismantling the oil pan 10 equipped with walls 10a extended upwards, the cross screws can be operated.
  • the combination with a lead frame 14 is very advantageous, as shown in FIGS. 7 and 8.
  • the lead frame 14 has lead frame walls 14c elongated upwards. After disassembling it, the cross screws can be operated.
  • the invention is an effective means of reducing the noise emissions from reciprocating piston machines of the type mentioned at the outset, preferably internal combustion engines, but also advantageously in the case of compressors.
