Definitions

  • the invention relates to an internal combustion engine with at least one piston which exerts strokes in a cylinder crankcase and cooperates by means of two connecting rods with two parallel synchronously rotating crankshafts in opposite directions.
  • a reciprocating unit EP 2 426 336 A2 which includes a reciprocating piston.
  • the reciprocating piston is connected by two connecting rods to two parallel crankshafts.
  • Each crankshaft is provided with a synchronizing gear, wherein both synchronizing gears are formed as spur gears and are mutually engaged in such a manner that said gears rotate in synchronism with the crankshafts in opposite directions.
  • the object of the invention is to design a high-level Hubkolbenaggregat with a reciprocating piston and two mutually parallel, connected by connecting rods with the reciprocating crankshaft and a means for compensating an asymmetry of the circulation of the crankshafts. It should ensure that the device can be easily implemented and contributes to a good function of the reciprocating piston unit.
  • the device for compensating a possible asymmetry of the course of the crankshafts contributes to the efficient operation of the internal combustion engine in an exemplary manner.
  • This is supported by the two scales setting cylindrical bearing washers and the piston pin, which are easy to manufacture in terms of structural design and favorable conditions.
  • the bearing washers are well received by the piston bores; as well as the first and second pin portions of the piston pins in the disc bores.
  • a step can be provided on the respective piston pin with a collar designed as a stop, which is supported on an inner side of an associated bearing disk.
  • the reversed arrangement of the piston pin ensures a targeted power transmission from the piston to the connecting rod.
  • the bearing washers For axial securing of the bearing washers are commercially available, cost-locking rings, which are effective between the piston bores and the bearing discs; corresponding retaining rings can also be used between the piston pin and the bearing discs. Due to the sophisticated constructive solution of the piston pin, i. the stage with trained as a stop collar is required for axial securing the piston pin in the pin holes only one locking ring. Finally, the bearing discs are provided in the region of the first and second pin portions to achieve an advantageous bearing base with disc thickening.
  • an outboard engine usable internal combustion engine 1 - Fig. 1 - Has at least one piston 2, which executes 4 strokes in the directions HRh and HRn in a piston bore 3 of a cylinder crankcase.
  • the internal combustion engine 1 operates as a four-stroke diesel engine with direct injection, and it is equipped with exhaust gas turbocharging - not shown.
  • the cylinder crankcase 4 carries a cylinder head 5, which defines a combustion chamber 6 together with the part of the piston bore 3.
  • at least one inlet valve 7 and one outlet valve 8 are provided, which are actuated by means of overhead camshafts 9 and 10.
  • the piston 2 is coupled to two connecting rods 11 and 12, which are in operative connection with two parallel crankshafts 13 and 14. Between the crankshafts 13 and 14 act two synchronization gears 15 and 16, which are mutually engaged via a spur gear 17. As a result, the synchronizing gears 15 and 16 rotate synchronously in opposite Dr1 and Dr2. Between the synchronization gears 15 and 16 extends a central longitudinal axis AA, which includes a central longitudinal plane of the piston 2 and the piston bore 3. On a piston bottom 18 of the piston 2 facing side, the connecting rods 11 and 12 bearing eyes 19 and 20 on. The latter are with the interposition of piston pin 21 and 22 with at opposite first and second outer sides 23 and 24 -. Fig.
  • the piston 2 provided first and second bearings 25 and 26 in operative connection.
  • the first and second bearings 25 and 26 together with the piston pins 21 and 22 shown as equal parts and the bearing eyes 19 and 20 of the connecting rods 11 and 12 each form a means 27 for compensating an asymmetry of the course of the crankshafts 13 and 14.
  • the device 27 has on the bearings 25 and 26 of the piston 2 via two substantially identical cylindrical bearing discs 28 and 29, which are rotatably mounted on the one hand in piston bores 30 and 31 and on the other hand disc bores 32, 33 and 34, 35 for receiving first and second bolt portions 36, 37th and 38, 39 of the piston pins 21 and 22.
  • the bolt portions 36 and 37, e.g. of the piston pin 21 are configured such that a diameter Du 1 of the first pin portion 36 is larger than a diameter Du 2 of the second pin portion 37 of the piston pin 21.
  • a step 40 with a as Stop 41 formed collar 42 is provided, which is brought adjacent to the second pin portion 37 to an inner side 43 of the associated bearing plate 29. With the interposition of a spacer ring 44, the collar 42 is supported on an inner side 45 of the bearing disk 29 directed towards the central longitudinal plane A-A.
  • the piston pins 21 and 22 are reversed to each other in the disc bores 32, 33, and 34, 35 used. Namely, in such a manner that the first pin portion 36 of the piston pin 21 moves in the disc bore 32 of the first bearing disc 28. In contrast, the first pin portion 38 of the piston pin 22 is received by the disc bore 35 of the second bearing disc 29.
  • first securing troughs 46 and 47 are used, which are provided by the sides 23 and 24 of the piston 2 in adjacent end portions 48 and 49 of the first pin portions 36 and 38 provided grooves 50 and 51 are.
  • the grooves 50 and 41 are in the Incorporated piston bores 30 and 31, and the retaining rings 46 and 47 are based on stops 52 and 53 of collars 54 and 55 of the bearing discs 28 and 29 from.
  • second locking rings 56 and 57 are provided. These are inserted near end portions 58 and 59 of the first pin portions 36 and 38 in grooves 60 and 61 of the disc bores 32 and 35 and in corresponding grooves of the pin portions 36 and 38, respectively.
  • bearing discs 28 and 29 are provided in the region of the first and second pin portions 36, 37 and 38, 39 with disc thickening 62 and 63 in order to achieve a targeted bearing base for the pin portions 36, 37 and 38, 39.
