Description

一种新型减速器外伸轴密封
技术领域
本发明涉及减速器密封,具体涉及一种新型减速器外伸轴密封。
背景技术
常用的各种减速器外伸轴密封与轴摩擦中任何时候都存在着渗漏的通道。轴径越大,通道就越多,即轴径越大渗漏量就越大。造成泄漏的原因主要有两方面:一是密封面上有间隙;二是密封两侧有压力差。
发明内容
本发明的目的,就是为了解决上述现有存在的问题,提供一种新型减速器外伸轴密封以减少密封两侧压力差从而减少渗漏。
为达到上述目的,本发明采用以下技术方案:一种新型减速器外伸轴密封,包括轴承环、减压孔、主密封、副密封;所述轴承环上开有减压孔与上箱盖或下箱盖轴承座上泄旁孔相通,降低密封面两侧的压力差,减少泄漏。轴承环上减压孔为均匀分布的若干个小孔,上箱盖和下箱盖轴承座上减压孔也为均匀分布的若干个连通小孔,同时,上箱盖和下箱盖轴承座上泄油孔与轴承环的配合面向内挖深2~3mm、宽4~5mm的越程槽与减压孔连通。所述外伸轴与轴承端盖处的主密封结构采用一道O形密封圈,一道L形密封环。所述副密封为带有副密封唇的防尘圈。

图2主密封结构,图中1-O形密封圈、2-L形密封环。
图3副密封结构。
具体实施方式
在使用时,应注意以下几点:
环境温度:在使用温度较高的情况下,应选用聚丙烯酯或硅、氟、硅氟橡胶。并应设法降低油箱中的油温。在使用温度过低的情况下,应选用耐寒橡胶;
压力:一般的油封承受压力能力差,压力过大时油封会变形。但此处,我们已经进行了减压,压力不会太高;
安装上的偏心程度:油封和轴配合时偏心过大,则其密封性会变差,特别是在轴转速高时尤为严重。如果偏心过大时,可采用“w”形断面的油封;
注意在油封的唇口应有一定量的润滑油,还要特别注意防止尘土浸人油封。
