一种密封圈以及使用该密封圈的分离轴承组件和汽车

Abstract

本实用新型涉及一种密封圈以及使用该密封圈的分离轴承组件和汽车,密封圈包括本体和唇部,唇部设置在本体一侧,本体与唇部的接合处设置有弧形过度段,唇部向径向外部延伸使得密封圈的开口逐渐变大。分离轴承组件包括轴承、左右卡簧以及滑套,轴承通过左右卡簧联接在滑套的端部上,在滑套与轴承之间设置有密封圈,密封圈的本体过盈地套接在滑套的端部,密封圈的唇部与外圈内壁间隙配合。密封圈有效减少滚道油脂和外界杂质及灰尘经由内圈与滑套间的间隙相互流动,以提升分离轴承组件的使用稳定性,延长其使用寿命。分离轴承组件具有质量轻、生产及装配工艺简单、防尘及防油渗漏性能良好等特点,可以广泛地使用在汽车发动机等部件上。
The utility model relates to a sealing washer and use release bearing subassembly and car of sealing washer, sealing washer include body and lip, and the lip is provided body one side, and the junction of body and lip is provided with the excessive section of arc, and the lip radius vector is extended to the outside makes the opening grow gradually of sealing washer. The release bearing subassembly includes bearing jump ring and sliding sleeve about, the bearing about through the jump ring hookup be provided with the sealing washer between sliding sleeve and bearing on the tip of sliding sleeve, the body interference ground of sealing washer cup joints the tip at the sliding sleeve, the lip and the outer lane inner wall clearance fit of sealing washer. The sealing washer effectively reduces raceway oil and fat and external impurity and dust and flows each other via the clearance between inner circle and sliding sleeve to promote the stability in use of release bearing subassembly, prolong its life. The release bearing subassembly has that the quality is light, production and assembly process is simple, dustproof and grease proofing seepage characteristics such as functional, can use on parts such as automobile engine widely.
