Description

混凝土输送泵的S管密封机构
技术领域
本实用新型涉及一种混凝土输送泵的S管密封机构,属于建设机械工程技术领域。
背景技术
现有的混凝土输送泵在长期工作中,其S管花键轴与轴承座间的密封件和轴承经常发生磨损故障,导致出现漏浆现象。
发明内容
本实用新型的目的是提供一种混凝土输送泵的S管密封机构,针对现有拖式混凝土输送泵S管花键轴与轴承座间的密封件和轴承经常发生磨损故障的不足,通过本实用新型防止混凝土细小颗粒进入S管花键轴和轴承座间的间隙细缝内,有利于延长密封件和轴承的使用寿命。
本实用新型的目的是通过以下技术方案实现的,一种混凝土输送泵的S管密封机构,包括S管花键轴,套置在S管花键轴上的轴承座,轴承座端的密封件,其特征是,S管花键轴、轴承座及轴承座端的密封件外套置密封环。
所述密封环的截面似呈亚铃状,与套置的轴承座、密封件、S管花键轴相吻合,即两端部的直径大于中部直径。
所述密封环采用耐酸碱夹布橡胶。
本实用新型是对现有混凝土输送泵S管花键轴与轴承座间的密封件和轴承经常发生磨损故障的结构改进,主要特点是在S管花键轴和轴承座之间套置一个密封环,本实用新型结构非常简单,成本又低廉,可有效防止混凝土细小颗粒进入S管花键轴和轴承座间的间隙细缝内,有利于延长密封件和轴承的使用寿命,本实用新型实用性很强,可用来改造现有混凝土输送泵。
附图说明
图1为本实用新型结构示意图;
图中,1轴承座,2密封环,3S管花键轴。
具体实施方式
结合附图和实施例进一步说明本实用新型,如图1所示,本实用新型在S管花键轴3、轴承座1及轴承座1端的密封件外套置密封环2;密封环2的截面似呈亚铃状,与套置的轴承座1、密封件、S管花键轴3相吻合,即两端部的直径大于中部直径;密封环采用耐酸碱夹布橡胶.混凝土输送泵在长期工作中,由于搅拌轴不断的旋转搅拌,使料斗内混凝土细小颗粒从S管花键轴3与轴承座1配合处的间隙渗透到轴承座内部,容易造成密封件和轴承磨损而发生故障,在S管花键轴3、轴承座1及轴承座1端的密封件外套置密封环2,防止混凝土细小颗粒进入S管花键轴3和轴承座1间的间隙细缝内,有利于延长密封件和轴承的使用寿命.
