(EN) PLAIN BEARING
(FR) PALIER LISSE
(JA) すべり軸受
Abstract
(EN)
 Provided is a plain bearing that is less susceptible to galling and also has an oil groove in the inner circumferential surface thereof. A cylindrical main bearing (2) that is formed by combining an upper bearing placed on the upper side and a lower bearing (20) placed on the lower side, and that rotatably supports a crank journal (1a) with an oil film formed between the crank journal (1a) and the main bearing (2), wherein the lower bearing (20) includes, among the inner circumferential surface of the lower bearing (20), an oil groove (23) formed in a low-load region (L) that is set in a range where the pressure from the oil film is low.
(FR)
 L'invention concerne un palier lisse qui est moins sensible au grippage et qui comporte également une rainure d'huile dans sa surface circonférentielle interne. L'invention concerne un palier principal cylindrique (2) qui est formé par la combinaison d'un palier supérieur placé sur le côté supérieur et d'un palier inférieur (20) placé sur le côté inférieur, et qui supporte de manière rotative un tourillon de vilebrequin (1a), un film d'huile étant formé entre le tourillon de vilebrequin (1a) et le palier principal (2), le palier inférieur (20) comprenant, parmi la surface circonférentielle interne du palier inférieur (20), une rainure d'huile (23) formée dans une région de faible charge (L) qui est définie dans une plage dans laquelle la pression issue du film d'huile est faible.
