Description

防水轴承
技术领域：本发明涉及一种机械领域使用的滚动轴承，特别是一种防水功能强的防水轴承。
背景技术：现有滚动轴承主要由外圈、内圈、滚动体和保持架四部分组成；它使用在各种机床、电机、水泵等作业机械上。在使用中，现有滚动轴承存在一个不足是，防水性较差，这使得在露天、水下、潮湿等环境作业机械中的轴承在运行中其内部常浸泡在水中，或水与杂质的混合体中，这不仅容易使轴承易生锈降低使用寿命，而且会常出现轴承被堵或卡住的情况发生，导致装置运行失常或酿成事故。
发明内容：本发明的目的在于，针对现有在滚动轴承在使用中存在的防水性能差，易生锈且易导致轴承使用寿命缩短或损坏的不足，而提出一种防水性能强，使用寿命长，运行平稳可靠的防水轴承。
通过下述技术方案可实现本发明目的，一种防水轴承，包括外圈、内圈、滚动体和保持架，其特征在于，还包括环状碟片形的密封盖片，外圈两个端面的内环设有台阶，内圈两端的圆周面上设有环形卡槽，密封盖片的内圆端卡在内圈的卡槽内，外圆端抵靠在外圈的端面上。
为便于安装，密封盖片的外径，小于外圈台阶端面的外径，大于外圈台阶端面的内径。
为提高防水性能，外圈内环台阶的端面的粗糙度不大于Ra0.4um。
为利于防水性能，密封盖片的厚度为0.10～0.2mm，密封盖片与外圈内环台阶端面的接触面为平面，其粗糙度不大于Ra0.4um。
本发明的效果在于：防水性能好，可有效防止水及杂质进入到轴承内腔，提高轴承的使用寿命，并使其能正常稳定运行,消除故障。这在于，本轴承在现有轴承的基础上，增加了环状碟片形的密封盖片及对外圈和内圈进行了相应的改进；密封盖片的内圆边端通过一定的压力压入内圈的环形卡槽内，外缘边端的平面抵靠在外圈的台阶端面上，因密封盖片较薄并具一定的弹性，其外缘边端能与外圈台阶端面紧密抵靠，从而使密封盖片能对轴承内腔形成一个良好的密封，达到本装置一个很好的防水效果。
下面结合附图及实施例对本发明进一步阐述：
附图说明：
附图1为本发明断面结构示意图；
附图2为本发明中密封盖片的平面示意图；
附图3为附图2中A～A处剖视图。
具体实施方式：
参见附图1、2、3，一种防水轴承，它主要由外圈1、内圈2、滚动体3、保持架4、密封盖片5组成。外圈1两个端面的内环设有台阶，台阶端面的粗糙度不大于Ra0.4um。内圈2两端的外圆周面上设上环形卡槽。密封盖片5为环状碟片形，其材料与轴承制作材料配备，其厚度为0.10～0.2mm，其与外圈1台阶端面的接触面为平面，其粗糙度不大于Ra0.4um。密封盖片5的内圆端卡在内圈2的卡槽内，外圆端抵靠在外圈1的台阶端面上。为便于安装，密封盖片5的外径小于台阶端面的外径，大于台阶端面的内径。密封盖片5的内径略小于内圈2的外径。
