ニサイクル機関クロスヘッドピン軸受の潤滑 : 軸受面の形状がだ円の場合

抄録

The crosshead-pin bearing equipped with axial oilgrooves in a two-stroke cycle diesel engine cannot produce such a thick oilfilm as to hold the bearing to be always free from troubles since the bearing is subjected to high load in a single direction besides a low speed. This paper refers to a theoretical analysis on the lubrication of a crosshead-pin bearing with an elliptical bearing and a circular journal. This bearing can remarkably increase the oilfilm thickness and is superior to the conventional bearing in load-carrying capacity and oilfilm exchanging ability as the wedge film action greatly increases due to the presence of two converging-diverging film shapes in load-carrying film.
