The bearing bush, which is a main part of the sliding bearing, directly contacts and rubs with the journal, and is required to have good frictional wear performance and mechanical properties, and is the most easily damaged part, in which both ends of the bearing bush are most easily worn.
Because the working condition of the engine frequently changes, the engine is frequently started and stopped, and boundary friction easily occurs, at the moment, two friction surfaces respectively adsorb a layer of lubricating oil film with the thickness of a few molecules by virtue of intermolecular attraction, and the metal surface is completely separated by the layer of boundary oil film. When the common main shaft bushing is under high load, a boundary oil film is easy to break, so that metal generates dry friction, strong abrasion is caused, even the surfaces are melted and mutually bitten and stuck together, and the damage source of the main shaft bushing is realized. Therefore, oil storage bodies are added at two end parts of the bearing bush, and the surfaces of the oil storage bodies are provided with ripples so as to continuously supply oil to boundaries and prevent oil films from breaking. However, the surface of the bearing bush is strip-shaped corrugation, and lubricating oil can only permeate along one direction, so that the lubricating oil on the inner surface of the bearing bush is insufficient, and the bearing bush is easy to damage.
