Title (EN) CONNECTING ROD AND CROSSHEAD-TYPE ENGINE PROVIDED WITH SAME
(FR) BIELLE ET MOTEUR DE TYPE À CROSSE LA COMPRENANT
(JA) 連接棒およびこれを備えたクロスヘッド型エンジン
Abstract:
(EN) The present invention suppresses pressure deformation of a bearing metal due to recessed parts such as an oil supply path or oil supply groove formed in a bearing surface at an end of a connecting rod, while preventing the bearing metal from being excessively thickened. A connecting rod (18) is provided with recessed parts (15, 16) which are formed in a bearing surface (8a) of an end (8A) of the connecting rod (18), and a bearing metal (11A) which is attached to the bearing surface (8a) and which has a half-cylindrical shape. When the opening width dimension of each of the recessed parts (15, 16) is defined as d and the thickness dimension of the bearing metal (11A) is defined as H, H is set so as to satisfy H>d·α and the range of the coefficient α is set so as to satisfy any one of: (a) α>0.6 in the case where the recessed parts are a hole and grooves and the opening width dimension d is less than 10 mm; (b) α=0.8 in the case where the recessed parts are a hole and grooves and the opening width dimension d is 10-40 mm; (c) α>0.5 in the case where all the recessed parts are holes and the opening width dimension d is less than 10 mm; and (d) α>0.6 in the case where all the recessed parts are holes and the opening width dimension d is 10-40 mm.
(FR) La présente invention concerne la suppression de déformation de pression d'un métal pour palier provoquée par des parties évidées telles qu'un trajet d'alimentation en huile ou une rainure d'alimentation en huile formé(e) dans une surface de palier au niveau d'une extrémité d'une bielle, tout en évitant que le métal pour palier ne soit excessivement épaissi. L'invention concerne une bielle (18) comprenant des parties évidées (15, 16) qui sont formées dans une surface de palier (8a) d'une extrémité (8A) de la bielle (18) et un métal pour palier (11A) qui est fixé à la surface de palier (8a) et qui présente une forme semi-cylindrique. Lorsque la dimension de largeur d'ouverture de chacune des parties évidées (15, 16) est définie comme d et que la dimension d'épaisseur du métal pour palier (11A) est définie comme H, H est défini pour satisfaire H>d·α et la plage du coefficient α est définie de manière à satisfaire l'une quelconque des équations suivantes : (a) α>0,6 au cas où les parties évidées sont un trou et des rainures et la dimension de largeur d'ouverture d est inférieure à 10 mm ; (b) α=0,8 au cas où les parties évidées sont un trou et des rainures et la dimension de largeur d'ouverture d est 10-40 mm ; (c) α>0,5 au cas où toutes les parties évidées sont des trous et la dimension de largeur d'ouverture d est inférieure à 10 mm ; et (d) α>0,6 au cas où toutes les parties évidées sont des trous et la dimension de largeur d'ouverture d est 10-40 mm.
(JA) 軸受メタルが過度に厚くなることを防止しながら、連接棒の端部の軸受面に形成されている給油通路や給油溝等の凹部による軸受メタルの圧力変形を抑制する。連接棒(18)は、その端部(8A)の軸受面(8a)に形成された凹部(15,16)と、軸受面(8a)に装着される半割り円筒状の軸受メタル(11A)とを備え、凹部(15,16)の開口幅寸法をdとし、軸受メタル(11A)の厚さ寸法をHとした場合に、H>d・αとなるようにHを設定し、係数αの範囲は、次のいずれかとした。 (a)凹部が穴と溝であり、開口幅寸法dが10ミリ未満の場合は、α>0.6。 (b)凹部が穴と溝であり、開口幅寸法dが10ミリ以上40ミリ以下の場合は、α=0.8。 (c)凹部が穴のみであり、開口幅寸法dが10ミリ未満の場合は、α>0.5。 (d)凹部が穴のみであり、開口幅寸法dが10ミリ以上40ミリ以下の場合は、α>0.6。
