Title (EN) PIN-BUSHING ASSEMBLY FOR ENHANCING A FLOW OF LUBRICATION IN A RECIPROCATING MECHANICAL SYSTEM
(FR) ENSEMBLE AXE-DOUILLE PERMETTANT D'AMÉLIORER UN ÉCOULEMENT DE LUBRIFICATION DANS UN SYSTÈME MÉCANIQUE À MOUVEMENT ALTERNATIF
Abstract: front page image
(EN) A pin-bushing assembly (10) for a connecting rod (12) is disclosed. The pin-bushing assembly (10) includes a connecting rod bushing (14) at least partially disposed within the connection rod (12); and a piston pin (16) at least partially disposed within the connecting rod bushing (14). One of the connecting rod bushing (14) and the piston pin (16) may include one or more segments (14a, 14b, 14c, 16a, 16b, 16c), and at least one of the connecting rod bushing (14) and the piston pin (16) includes a surface feature (26, 32, 38, 40) for enhancing delivery of lubrication at the interface between the connecting rod bushing (14) and the piston pin (16). The surface features can be, for example, circumferential lubricant grooves (26), axial grooves (32), dimples (38, 40), and the like. A connecting rod assembly (100) that includes the pin-bushing assembly (10) and an anti-rotation feature (46) is also disclosed.
(FR) L'invention concerne un ensemble axe-douille (10) destiné à une bielle (12). L'ensemble axe-douille (10) comprend une douille (14) de bielle disposée au moins partiellement à l'intérieur de la bielle (12) ; et un axe de piston (16) disposé au moins partiellement à l'intérieur de la douille (14) de bielle. La douille (14) de bielle et/ou l'axe de piston (16) peuvent comprendre un ou plusieurs segments (14a, 14b, 14c, 16a, 16b, 16c), et la douille (14) de bielle et/ou l'axe de piston (16) comprennent une caractéristique de surface (26, 32, 38, 40) servant à améliorer la distribution de lubrification au niveau de l'interface entre la douille (14) de bielle et l'axe de piston (16). Les caractéristiques de surface peuvent, par exemple, consister en des rainures circonférentielles (26) pour lubrifiant, des rainures axiales (32), des creux (38, 40), et analogues. L'invention concerne également un ensemble bielle (100) comprenant l'ensemble axe-douille (10) et une caractéristique antirotation (46).
