Abstract

本实用新型涉及的耐用油封适用于作汽车、摩托 车减振系列的密封件,为内含换环状金属骨架的耐油 橡胶体,其特征在于所述环状金属骨架(2)的截面为 J形,密封唇的表面附着有聚四氟乙烯保护层(1)。 本实用新型由于具有所述技术特征而具有较强的抗 变形能力,及具有耐高温,耐磨性,耐磨蚀性好等优 点,因而使用寿命长。

Description

本实用新型涉及的密封件,特别是一种用于汽车、摩托车减振系列的密封垫。
现有技术中用于汽车、摩托车减振系列的密封垫存在不耐高温、不耐摩擦和腐蚀的缺陷,需要经常更换。此外,由于密封垫的骨架结构不合理,使密封垫容易变形。
本实用新型的目的是提供一种既耐高温、又耐摩擦和腐蚀的骨架式耐用油封。
本实用新型的上述目的是通过这样的结构实现的,即它为内含环状金属骨架的耐油橡胶圈体,其密封唇外周的沟槽内套有螺旋弹簧圈,其特征在于所述环状金属骨架的截面为J形,密封唇的表面附着有聚四氟乙烯保护层。
本实用新型的上述结构由附图进一步说明。
附图为本实用新型的剖面示意图。
参见附图,在耐油橡胶圈体1内有一个截面为J形的环状金属骨架4,耐油橡胶圈体内的密封唇外周的沟槽内套有螺旋弹簧圈2,密封唇表面附着有聚四氟乙烯保护层1。所述聚四氟乙烯保护层系采用模具结构组合到密封唇表面的。
本实用新型由于采用了所述骨架结构,因而具有较强机械强度和抗变形能力;由于在密封唇上附着了聚四氟乙烯保护层而具有摩擦系数小,耐高温,耐磨性,耐腐蚀性能好等优点,延长了密封垫的使用寿命。
