SPLIT BEARING ARRANGEMENT IN A MACHINE HOUSING, ESPECIALLY A CRANKSHAFT SLIDING BEARING FOR RECIPROCATING PISTON MACHINES

摘要

A split bearing arrangement in a machine housing, particularly a crankshaft journal bearing for piston machines. The split bearing arrangement including a bearing block and a bearing cover that are made of materials of different hardnesses. In order to provide a material anchoring between the bearing cover and the bearing block that can be subjected to high loads and is cost-effective to produce, the bearing arrangement provides the bearing cover, which is made of an iron material, with cutting-edge like projections protruding above its clamping faces and, furthermore, provides grooves in the corresponding clamping faces of the bearing cover and the bearing block. These grooves in an initial mounting of the bearing cover with the required force serve to receive the material of the bearing block that is displaced in the pressing-in process when the projections are pressed into the opposite clamping faces of the bearing block, which is made of a light metal.
