Description

托辊密封圈
技术领域
本实用新型涉及密封技术,具体是一种托辊密封圈。
背景技术
矿井下使用的皮带式输送机上安装有大量的托辊,在井下长期的运行过程中,托辊内部的轴承部位会附着上大量的灰尘,煤泥,水等物质,影响着轴承的正常工作,缩短轴承的使用寿命。而目前针对轴承的防尘、防水、防煤泥所采用的密封件存在密封预紧力不足、不能够自密封的问题。基于此,有必要发明一种具有自密封功能和强密封预紧力的新型密封件。
发明内容
本实用新型为了解决现有密封件密封预紧力不足和缺少自密封功能的问题,提供了一种托辊密封圈。
本实用新型是采用如下技术方案实现的:托辊密封圈,包括密封圏体,密封圏体的端面内侧设有内环形唇边,密封圏体的端面外侧设有外环形唇边;内环形唇边的高度小于外环形唇边的高度。
使用时,密封圏体套在托辊轴上,外环形唇边与托辊轴承的唇边接触,内环形唇边与托辊轴承的挡圈接触,外环形唇边与内环形唇边共同围成密封用气腔,密封用气腔不仅为轴承的密封提供了足够的密封预紧力,而且使得密封圏体具有了自密封功能。基于上述优点,本实用新型所述的托辊密封圈不仅能实现对灰尘、水、煤泥的有效密封,而且可以承担固定、往复和旋转运动的密封。
本实用新型结构简单,设计合理,有效解决了现有密封件密封预紧力不足和缺少自密封功能的问题,适用于托辊轴承的密封。
附图说明
图1是本实用新型的结构示意图。
图2是图1的A-A剖视图。
图中:1-密封圈体,2-内环形唇边,3-外环形唇边。
具体实施方式
托辊密封圈,包括密封圏体1,密封圏体1的端面内侧设有内环形唇边2,密封圏体1的端面外侧设有外环形唇边3;内环形唇边2的高度小于外环形唇边3的高度。具体实施时,密封圏体采用橡胶制成,具有耐老化、耐酸碱、耐高温、耐磨损、耐腐蚀的优点。
