Description

自密封双列圆锥滚子轴承
技术领域
本发明涉及一种自密封双列圆锥滚子轴承，属于轴承技术领域。
背景技术
在某飞机部件中，用于旋转轴固定端支承的是自密封双列圆锥滚子轴承。该轴承主要可承受轴向力、径向力及倾覆弯矩，且轴承需密封，为尽量控制轴承重量、保证轴承载荷，鉴于以往的自密封双列圆锥滚子轴承，密封所用空间大，未能满足所需工况的使用要求，急需设计一种防污能力强、使用寿命长、受力性能好、占用空间少的自密封双列圆锥滚子轴承。
发明内容
鉴于已有技术存在的缺点，本发明的目的是解决现有技术无法同时满足防污能力强、使用寿命长、减少密封件占用空间等问题。
本发明采取的技术方案：一种自密封双列圆锥滚子轴承，包括双滚道外圈、双滚道内圈、内隔圈、滚子、保持架及密封圈，所述的密封圈钢骨架上部延伸并嵌套固定在轴承外圈止口上，密封圈橡胶圈采用三唇结构并与双滚道内圈挡边过盈配合。
本发明的有益效果：本发明的自密封双列圆锥滚子轴承不仅实现自密封，而且密封性能高，使用寿命长，受力能力好，最大限度地降低轴承重量。
附图说明
图1是本发明实施例的示意图；
图2是本发明实施例的密封圈局部放大图。
图中：1、双滚道外圈，2、双滚道内圈，3、内隔圈，4、滚子，5、保持架，6、密封圈。
具体实施方式
下面结合附图说明实施例：
用于飞机某部件的旋转轴固定端支承的自密封双列圆锥滚子轴承，包括双滚道外圈1、双滚道内圈2、内隔圈3、滚子4、保持架5及密封圈6；所述的密封圈6的钢骨架上部延伸并嵌套固定在轴承双滚道外圈1的止口上，密封圈6橡胶圈采用三唇结构并与双滚道内圈2挡边过盈配合，内外两唇的双层密封，有效防止油脂的流出和外部杂质的进入，提高密封性能；尖锐的唇形结构，降低了摩擦系数，减少对转速及寿命的影响；较窄的密封圈6橡胶圈节约了空间，降低了轴承重量。钢骨架与橡胶圈的合理结合，增强了密封圈6的强度和弹性，装配时可机压，并能有效压紧。
