探入式轴承密封组件
技术领域
本发明涉及一种高转速、低噪音、耐高温探入式轴承密封组件，该密封组件用于高速电机轴承上，属于滚动轴承技术领域。
背景技术
随着市场经济的迅猛发展，用户对轴承质量的要求越来越高，特别是电机市场对密封轴承高转速时的温升，异常声，漏脂及能耗提出了更高的要求。
作为精密密封电机轴承，技术含量高，加工精度高，附加值高，要求在运转中具有较高的综合性能，一般深沟球轴承的密封为接触式密封和非接触式密封两种。接触式密封用在电机上，摩擦力矩大，非接触式密封又漏油。急需研究一种密封结构介于接触与非接触之间。满足电动轴承的启动力矩及不漏油的功能。
发明内容
根据现有技术存在的缺陷，本发明的目的是提供一种能够满足密封效果，结构简单；装配方便的探入式轴承密封组件。
为达到上述目的，本发明所采用的技术方案为：一种探入式轴承密封组件，密封组件一端嵌入到轴承外圈内径，另一端延伸到轴承内圈外径，所述轴承内圈外径设置沟槽，密封组件靠近轴承内圈的一侧设置有第一密封唇和第二密封唇，第一密封唇与轴承内圈外径间隙配合，第二密封唇伸入沟槽内，并且第二密封唇的侧壁与沟槽侧壁接触配合。
进一步地，所述密封组件为包裹着刚性骨架的橡胶密封体。
进一步地，所述橡胶密封体为氢化丁腈橡胶密封体。
进一步地，所述密封组件应用于电机用深沟球轴承。
本发明的有益效果为：本发明结构上采用非接触式独特的手枪式形状密封，该结构具有轴向、径向多层密封，密封效果完全达到接触式密封效果。且具有启动力矩低，噪音低，能耗低等特点。

具体实施方式
为了使本发明的结构的功能更加清晰，下面结合附图和具体实施方式对本发明的技术方案作进一步说明。
一种探入式轴承密封组件，应用于电机用深沟球轴承，所述密封组件一端嵌入到轴承外圈2内径，另一端延伸到轴承内圈1外径，所述轴承内圈外径设置沟槽7，密封组件4靠近轴承内圈的一侧设置有第一密封唇5和第二密封6唇，第一密封唇5与轴承内圈1外径间隙配合，第二密封唇6伸入沟槽7内，并且第二密封唇6的侧壁与沟槽7侧壁接触配合。
进一步地，所述密封组件4为包裹着刚性骨架的橡胶密封体。
进一步地，所述橡胶密封体为氢化丁腈橡胶密封体。具有耐热性、耐油性及耐候性，比传统的丁腈橡胶性能更加优良。
本专利发明了该结构的密封形式，侧面与内圈沟槽贴合，起到了密封的作用，阻力小，又不漏油。
本专利为贴合式接触，第二密封唇的侧壁与沟槽侧壁接触配合，并保证在轴向上具有一定的压缩量。
本专利密封密封结构远离钢球的一侧与轴承外圈、内圈为间隙配合，第二密封唇侧壁与内圈沟槽贴合，第一密封唇与轴承内圈外径间隙配合，摩擦阻力很小。
本发明轻量化设计，异型结构，创新设计出有利于轴承装配和热胀冷缩要求的新结构型式。采用ZWZ品牌长寿命专用润滑脂，提高轴承使用寿命。
以上列举的仅是本发明的最佳实施例。显然，本发明不限于以上实施例，还可以有许多变形。本领域的普通技术人员能从本发明公开的内容直接导出或联想到的所有变形，均应认为是本发明的保护范围。
