Title (EN) SEALING STRUCTURE OF HYDRAULIC CYLINDER
(FR) STRUCTURE D'ÉTANCHÉITÉ DE VÉRIN HYDRAULIQUE
(ZH) 一种液压油缸的密封结构
Abstract: front page image
(EN)A sealing structure of a hydraulic cylinder is provided. The cover of the hydraulic cylinder includes a dustproof ring (4), support rings (7,9), a sealing ring (8), a cushion ring (10) and sliding sleeves (6,11), wherein two support rings are symmetrically arranged at two sides of the sealing ring. The sealing structure can protect the sealing ring and a piston rod better, and reduce the deflection of the piston rod.
(FR)La présente invention a trait à une structure d'étanchéité d'un vérin hydraulique. Le couvercle du vérin hydraulique inclut une bague étanche aux poussières (4), des bagues de soutien (7, 9), un joint d'étanchéité (8), une bague d'amortissement (10) et des manchons baladeurs (6, 11), deux bagues de soutien étant disposées symétriquement sur deux côtés du joint d'étanchéité. La structure d'étanchéité permet de mieux protéger le joint d'étanchéité et une tige de piston, et de réduire la déviation de la tige de piston.
(ZH)一种液压油缸的密封结构,在该液压油缸缸盖上包括有防尘圈(4)、支承环(7,9)、密封环(8)、缓冲环(10)、滑动轴套(6,11),其中,在密封环两侧对称安装两个支承环。该密封结构能够更好地保护密封环和活塞杆,减少活塞杆挠曲变形。
