Abstract
The invention relates to a connecting rod-bearing combination comprising a bearing for a small connecting rod eye of a connecting rod which serves to receive a piston pin that supports a piston. The invention also relates to a method for producing a connecting rod-bearing combination of the aforementioned type. The aim of the invention is to be able to exert an influence on the connecting rod-piston combination whereby enabling a fine tuning of the oscillating masses. To this end, the invention provides a connecting rod-bearing combination, which is post-machined in the area of the small connecting rod eye during which material is removed form a mass that corresponds to the difference between the oscillating mass of the connecting rod-bearing combination and a stipulated oscillating mass. The method for producing the connecting rod-piston combination is characterized in that during the removal of material, it is determined how much material mass on the connecting rod-bearing combination is to be removed in order to obtain a stipulated connecting rod-piston combination of a specified mass and mass distribution. The connecting rod-bearing combination is subsequently post-machined in the area of the small connecting rod eye during which material is removed to the extent of the determined mass.
