Title: (EN) SEALING DEVICE
(ZH) 密封装置
Abstract: front page image
(EN) Provided is a sealing device with which decreases in sealing performance can be avoided and friction resistance occurring in a lip member can be reduced. A sealing device (1) is provided with an annular lip member (10) made of a resin material, and an annular spring member (20) made of a metal material. The lip member (10) has a lip base (11), an outer peripheral lip (12), and an inner peripherallip (13). The spring member (20) has an annular spring base (21) encircling an axis line (x), an outer peripheral pressing part (22) for pressing on the outer peripheral lip (12), and an inner peripheral pressing part (23) for pressing on the inner peripheral lip (13), and the spring member (20) is accommodated in an accommodating groove (14). The outer peripheral pressing part (22) has a plurality of outer peripheral pressing pieces (24), and the inner peripheral pressing part (23) has a plurality of inner peripheral pressing pieces (25). The outer peripheral pressing pieces (24) have incisions (26) that extend along the axis line (x) and that do not reach a high-pressure-side edge (24a) of the outer peripheral pressing part (22), and the inner peripheral pressing pieces (25) have incisions (27) that extend along the axis line (x) and that do not reach a high-pressure-side edge (25a) of the inner peripheral pressing pieces (25).
(ZH) 本发明提供一种密封装置,其能够避免密封性能降低,并且减小唇部件产生的摩擦阻力。密封装置(1)具有树脂材料制的环状唇部件(10)、以及金属材料制的环状弹簧部件(20)。唇部件(10)具有唇基部(11)、外周侧唇(12)以及内周侧唇(13)。弹簧部件(20)具有绕轴线(x)呈环状的弹簧基部(21)、用于按压外周侧唇(12)的外周按压部(22)、以及用于按压内周侧唇(13)的内周按压部(23),并且被收纳在收纳槽(14)内。外周按压部(22)具有多个外周按压片(24),内周按压部(23)具有多个内周按压片(25)。外周按压片(24)具有沿轴线(x)延伸的未到达外周按压片(22)的高压侧缘(24a)的切口(26),内周按压片(25)具有沿轴线(x)延伸的未到达内周按压片(25)的高压侧缘(25a)的切口(27)。
