行走马达浮动油封

1、浮动油封浮动油封常用于工程机械行走部分的行星减速器，对该部件端面进行动态密封由于其可靠性高，近几年也用作挖泥船斗轮输出轴的动态密封此类密封属于机械密封，一般由铁合金材料的浮环及配套的丁腈橡胶0形密封圈组成浮环成对使用，一个随旋转部件转动，一个相对静止.浮动油封的密封原理是：两个浮环靠0形密封圈受轴向压缩 后的变形，产生对浮环密封端面的压紧力 随着密封端面的均匀磨损，这种由0形密封圈 储存的弹性能量逐步释放，从而起到轴向补偿作用在设定的时间内密封面能保持良好 的贴合,一般密封寿命在 4000h以上浮动油封是一种特殊型式的机械密封，是为适应恶劣的工作环境而发展起来的一 种紧凑型的机械密圭寸方式，它

2、具有抗污染能力强，耐磨,耐冲击，工作可靠，端面磨损自 动补偿，结构简单等优点，在工程机械产品上应用最为普遍，在各种输送机，砂处理设备混凝土设备上也应用广泛目前在煤矿机械上主要用于刮板输送机的链轮，减速器以及采煤机的传动机构和摇臂，滚筒等处.此类密封产品在工程机械设备应用较为普遍和成 熟,但在其他行业由于用量少，缺乏基础理论数据和使用经验 ，使用过程中失效现象较 为普遍,难以达到预期效果.性质：非接触式密封的一种。结构特点及其密封原理如图所示，浮环与转动轴之 间保持一定的间隙，可以自由浮动，但不能与转轴一起转动，只能作径向滑移浮动， 并在重力作用下与轴中心保持一定的偏心。当转轴转动时，从浮动油封

3、外界输入密封液（常采用油液）在转轴与浮环的间隙处形成油膜。因受轴转动时产生油楔动力的作用，使油膜内保有一定的油膜压力，使浮环能自动维持与轴中心“对 中”，从而使间隙量大大减小，有效地实现了对流体介质泄漏的密封。其优点是密封性能稳定，可靠，寿命长；密封的工作参数范围较宽（工作压力可达30兆帕，工作温度为-100200C ）;特别适合对离心式压缩机中气体介质的密封，还可实现对大气环 境不泄漏，适宜易燃 、易爆、有毒、贵重气体介质的密封。缺点是浮环加工要求高， 需要专门的密封油系统；存在较多的内部泄漏，但本质上仍属内部循环性质的泄漏， 这与机械密封的泄漏有质的区别。广泛应用于离心式压缩机的动密封品牌
