Connecting rod-bearing combination for adjusting and reducing oscillating masses of a connecting rod-piston-combination and method for producing a connecting rod-bearing combination of this type

摘要

The invention relates to a connecting rod-bearing combination comprising a bearing (1) for a small connecting rod eye (6) of a connecting rod (5) 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 (6) during which material is removed from 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 (6) during which material is removed to the extent of the determined mass.
