Abstract
A crosshead-pin bearing equipped with axial oil grooves in a two-stroke cycle diesel engine cannot form an oil film adequate to keep the bearing trouble free at all times, because the bearing is subjected to high load in a single direction besides a low oscillating speed. This paper refers to a theoretical analysis of the lubrication of a crosshead-pin bearing system with a circular journal and an elliptical bearing. The bearing with a proper bearing ellipticity produces a considerably thick oil film and is superior in load-carrying capacity and oil-film exchanging ability to the conventional bearing, since the wedge film action greatly increases due to the presence of two converging-diverging clearance shapes in the load-carrying film.
