PLEUEL MIT EINEM MEHRLAGIGEN THERMISCH GESPRITZTEN PORÖSEN LAGERSCHICHT

摘要

Bearing shells are inserted into the connecting rod eyes of connecting rods in internal combustion engines. The insertion of the bearing shells increases the complexity of the production process which can lead to errors being made. The aim of the invention is to provide a method for producing connecting rod bearings which are easier to install. According to the invention, a microporous aluminium bronze plasma-coating is applied to the large connecting rod eye (3). The connecting rod eye is then opened by removing the bearing cover (9), thus breaking the plasma coating (16). The cover (9) is subsequently screwed back on and the actual lining finished by fine spindling. The plasma coating (16) has an annular groove (32) to improve the oil retention volume. The invention is suitable for use in internal combustion engines.
