Crankshaft for diesel engines comprises connecting rod pins and/or main bearings having bearing surfaces with a variable width, the surface pressure acting in a specific region of the bearing surface can be adjusted to the force

摘要

Crankshaft comprises bends consisting of connecting rod pins (1), crank arms (2a, 2b) and main bearings (3a, 3b). The bearing surfaces (1a, 3c, 3d) of the connecting rod pins and/or the main bearings have a variable width so that the surface pressure acting in a specific region of the bearing surface can be adjusted to the force acting on it. Preferred Features: Reduction of the variable width from the widest width of the bearing surfaces is carried out by transitions (4a, 4b) corresponding to a basket geometry. The basket geometry can be produced by grinding, cutting or eroding.
