Parametric Study for Design Factors on Engine Bearings by using TEHL Analysis 2002-01-0298

As the downsizing and lightening of the engine are designed, the compact and lightweight of the housing should be required. Therefore, both the engine bearing and the housing are greatly deformed under the severe condition, and a heat generation due to the friction loss increases in the bearings. In this study, on the connecting rod bearing for the automotive engine, the bearing design factors as the oil inlet temperature, the rotational speed, the bearing clearance and the bearing length, are changed as a parameter. The influences of the design factors for the performance of the connecting rod bearing are investigated by using TEHL analysis (Thermo ElastoHydrodynamic Lubrication theory analysis).
