Title (EN) HALVED BEARING
(FR) DEMI-PALIER
(JA) 半割軸受
Abstract:
(EN) A halved bearing (10) according to an embodiment comprises: a semi-cylindrical bearing body (19) having an inner circumferential surface (12) that slides against a counterpart shaft; and a first groove (111) formed in the inner circumferential surface (12) along a circumferential direction of the inner circumferential surface (12). In a cross section of the bearing body (19) passing through the first groove (111) and being parallel to the circumferential direction, an angle θ formed between a line connecting an end, on the inner circumferential surface side, of a mating surface on the downstream side in the rotating direction of the counterpart shaft and a center of an arc forming an outer circumferential surface (11) and a line connecting the center and an end, in the circumferential direction, of the first groove (111) on the upstream side in the rotating direction of the counterpart shaft satisfies 90°≤θ≤105°.
(FR) Un mode de réalisation de la présente invention concerne un demi-palier (10) comprenant : un corps de palier semi-cylindrique (19) ayant une surface circonférentielle interne (12) qui coulisse contre un arbre homologue; et une première rainure (111) formée dans la surface circonférentielle interne (12) le long d'une direction circonférentielle de la surface circonférentielle interne (12). Dans une section transversale du corps de palier (19) traversant la première rainure (111) et étant parallèle à la direction circonférentielle, un angle θ, formé entre une ligne reliant une extrémité, sur le côté surface circonférentielle interne, d'une surface d'accouplement, sur le côté aval, dans la direction de rotation de l'arbre homologue à un centre d'un arc formant une surface circonférentielle externe (11) d'une part et une ligne reliant le centre à une extrémité, dans la direction circonférentielle, de la première rainure (111) sur le côté amont dans la direction de rotation de l'arbre homologue d'autre part, s'inscrit dans l'encadrement 90° ≤ θ ≤ 105°.
(JA) 一実施形態に係る半割軸受(10)は、半円筒形状であって相手軸と摺動する内周面(12)を有する軸受本体(19)と、内周面(12)において内周面(12)の周方向に沿って形成された第1溝(111)とを備え、軸受本体(19)の、周方向に平行でありかつ第1溝(111)を通る断面において、相手軸の回転方向下流側にある合せ面の内周面側の端と外周面(11)を形成する円弧の中心とを結ぶ線と、第1溝(111)の周方向の端であって相手軸の回転方向上流側の端と中心とを結ぶ線とのなす角度θが90°≦θ≦105°を満たす。
