Definitions

  • the invention relates to a reciprocating piston internal combustion engine, preferably a four-cylinder type, with at least one vibration-damping balance shaft, which is rotatably mounted in a bearing housing held on a cylinder crankcase by means of a screw connection.
  • support between the bearing housing and the crankcase is to be achieved in that the cheeks of the bearing housing are supported on walls of a recess in the crankcase.
  • the cheeks of the bearing housing are supported on walls of a recess in the crankcase.
  • the object of the invention is to fasten the bearing housing of the balance shaft to the crankcase in such a way that the rotating inertial forces are supported in a functional manner while avoiding complex manufacturing measures.
  • the main advantages achieved with the invention are the fact that the conical approach of the screw or the nut and the chamfer on the bearing housing support the occurring forces acting transversely to the screw axis in a functional manner.
  • the stud screw has a conical projection which cooperates with a chamfer on the crankcase for support, as a result of which notch effects are kept away from the threaded stud of the stud screw.
  • a reciprocating piston internal combustion engine 1 comprises a cylinder crankcase 2, on the longitudinal side 3 of which a balancer shaft 4 extends, which serves for vibration damping (inertial forces, gas forces).
  • the balance shaft 4 has balance weights 5, 6 and rotates at double the crankshaft speed in a bearing housing 7, which is formed by two housing halves 8, 9.
  • the housing halves 8, 9 are held in position by means of screws 10, 11.
  • the bearing housing 7 is also held by means of screws 12, 13 which are arranged at a distance from one another and are provided at 14 and 15 (FIG. 3). 7 mounting sections 16, 17 are attached to the cylinder crankcase 2 for receiving the bearing housing.
  • the screw 12 (at 14) and the screws, not shown, at 15 are formed by conventional hexagon screws.
  • the screw 13 is represented by a stud 24, the threaded pin 25 of which is screwed into a threaded bore 26.
  • the threaded pin 25 is supported by means of a conical projection 27 on a corresponding chamfer 28 of the cylinder crankcase 2, whereby forces acting on the threaded pin 23 are supported.
  • a screw nut 29 of the stud screw 22 has a conical projection 30 which interacts with a corresponding chamfer 31 of the bearing housing 7.
  • the screw nut 29 is accessible via a recess 32 in the bearing housing 7.
