Description

一种密封滚轮轴承
技术领域
本实用新型涉及一种轴承，尤其是涉及可安装于叉车门架系统、内圈固定外圈旋转，低速运转轴承的一种密封滚轮轴承。
背景技术
常规的滚轮轴承，一般都有简单的密封圈，或防尘盖。防尘效果一般，由于内圈和防尘盖之间存在间隙，因此难以消除灰尘杂质进入滚道内，导致滚道阻塞而被卡死或降低轴承滚子和滚道的精度。同时，轴承内轮滑脂会从空隙流失，使得轴承经常因缺轮滑脂而发热甚至氧化。而且密封过程中密封圈容易脱落，导致防尘效果和寿命大大降低，无法满足某些工况要求。
发明内容
本实用新型的目的在于提供构简单合理、设计巧妙，不仅可以有效密封，而且提高轴承使用寿命的一种密封滚轮轴承。
本实用新型设有外圈、内圈、2排滚子、弹簧圈和防尘盖；
所述2排滚子的端面贴紧，内圈支撑滚子，外圈定位滚子，滚子、内圈和外圈三个部件紧密贴合在一起；弹簧圈外径与外圈孔径配合，设在防尘盖上的凹槽扣紧弹簧圈并装配在外圈的孔径上，防尘盖一端贴紧内圈并使防尘盖定位，外圈弹簧和防尘盖的配合。
本实用新型的有益效果是：
1、采用双排滚子，其滚子端面贴紧来作为转动核心，大大增加了滚轮轴承的冲击载荷能力，转动灵活，使得更高效地起支承和引导作用。
2、密封装置简单合理、设计巧妙，具有良好的防尘效果、密封性能和弹性性能，能隔绝外界飞尘杂质。同时，轴承运转过程能有效防止油脂流失，有效延长滚轮的工作寿命。
附图说明
图1为本实用新型实施例的结构剖视图。
在图1中，各标记：1——外圈，2——滚子，3——内圈，4——防尘盖，5——弹簧圈。
具体实施方式
如图1所示，本实用新型实施例设有外圈1、内圈3、滚子2、防尘盖4和弹簧圈5。两排滚子2端面互相贴紧，内圈3滚道支撑滚子2，外圈1定位滚子使得三个部件精密贴合在一起。弹簧圈5的外径能与外圈1的孔径孔轴配合，防尘盖（截面为凹形）4的凹槽上扣紧弹簧圈5，然后装配到外圈1的孔径上，防尘盖4一端贴紧内圈3，由于弹簧圈5被压缩和弹力作用，使得防尘盖4定位，而且不易脱落，外圈1弹簧圈5和防尘盖4的配合，使得整个滚轮轴承内部具有优良的密封防尘效果。而且设计新颖，经济效益高。
