【技术实现步骤摘要】
本技术涉及一种立装式搅拌机用密封轴承座。
技术介绍
参见图1,顶插立装式搅拌机设计的难点在于:搅拌机工作在浆料池(槽)中,翻滚飞溅的浆料易于进入轴承壳内,轴承壳内的润滑油也容易于泄漏到浆料中。因此,轴和轴承壳的密封非常重要。通常的解决方法是在采用高效动密封元件的同时,限制搅拌容器里浆料的高度,使得轴承壳端面远高于浆料液面。从图1中可以看出,其一,轴承壳和轴之间的环形间隙垂直向下,极易漏油,再好的动密封件时间长了还是要漏油的。其二,搅拌机轴悬臂支承,搅拌机浆叶装在轴的最外端。旋转时,浆叶产生的不平衡离心力会把轴摔弯。而且,转速越高、轴的旋臂越长这种趋势就越大。
技术实现思路
本技术的目的在于克服现有技术中存在的上述不足,而提供一种结构设计合理的立装式搅拌机用密封轴承座,解决了轴承壳漏油和浆液飞溅污染润滑油的问题,且可使得搅拌机浆叶转动所产生的不平衡离心力对搅拌轴的弯矩大大减小。本技术解决上述问题所采用的技术方案是:一种立装式搅拌机用密封轴承座,其特征在于:包括上轴承座、轴承、上防尘盖、下轴承座、轴承壳、防尘套、外防尘盖和里防尘盖;上轴承座内开有上安装孔,上安装孔的孔壁上设置有上轴承安装区;轴承的内圈固定在上轴承座的外周上;上防尘盖固定在上轴承座的外周上,并将轴承覆盖住;下轴承座位于上轴承座的正下方;下轴承座内开有下安装孔,下安装孔的孔壁上设置有下轴承安装区;里防尘盖中开有密封孔;外防尘盖中开有外防尘盖孔;外防尘盖与里防尘盖固定;轴承壳上端与上轴承座固定,下端与下轴承座固定;防尘套活动套装在轴承壳外;防尘套的上端与轴承的外圈固定,下端与外防尘盖固定。本技术所述的轴承 ...
