Description

托辊用注油式柱塞密封圈
本实用新型涉及一种托辊用注油式柱塞密封圈。
目前,皮带输送机托辊中的密封装置,一般采用迷宫式密封件。这种密封件由两个部件组成,一个部件装在轴上,与轴一起转动,另一个部件装在托辊的孔中并随托辊转动。这种密封件虽可以起到密封的作用,但由于两个部件之间的间隙较大,因此存在着密封性能不好、安装不方便和不能给轴承注油等缺点。
本实用新型的目的是提供一种密封性能好、安装方便且能给轴承注油的托辊用注油式柱塞密封圈。
本实用新型的任务是这样实现的:在柱塞密封圈的外表面上设有若干条锯齿状环形密封齿,内表面上设有梯形槽,在柱塞密封圈的端面上设有注油孔。
上述柱塞密封圈由橡塑材料制成。
由于本实用新型采用上述结构形式的柱塞密封圈,因此与背景技术相比,具有密封性能好、安装方便且能给轴承注油等优点。
下面结合附图和实施例对本实用新型作进一步的描述。
图1是本实用新型的结构示意图;
图2是图1的左视图。
如图1、图2所示,本实用新型的柱塞密封圈,在柱塞密封圈1的外表面上设有3条锯齿状环形密封齿2,内表面上设有梯形槽3,在柱塞密封圈1的端面上设有注油孔4。柱塞密封圈1由橡塑材料制成。外表面上设有的锯齿状环形密封齿2还可以在2~6条之间选择,以满足密封的要求。
本实用新型的工作原理是:柱塞密封圈上设置的注油孔直通托辊的轴承部位,当轴承缺油时,不需取下托辊,可用黄油枪从注油孔中直接注入黄油,可避免托辊因轴承缺油造成轴承干转而损坏。另外利用橡塑材料的弹性,把柱塞密封圈的外径与托辊轴承孔的内径过盈配合,使柱塞密封圈直接装入轴承孔中,将轴承密封严实。
