Description

全密封免维护托辊
技术领域:
本实用新型涉及皮带输送机中的托辊,具体的说是一种全密封免维护托辊。
背景技术:
目前工矿企业中的托辊,使用寿命短、转动不灵活且跌落后有较大的轴向窜动现象。在输送皮带机中托辊一但出现问题直接影响整个输送环节的正常工作,而且托辊长期在这类恶劣的环境下工作,水和脏物会沿轴头侵蚀到轴承组件内部。
发明内容:
本实用新型的目的是提供一种全密封免维护托辊,其密封性能好,使用寿命长,转动灵活,且防轴向窜动。
本实用新型的技术方案如下:
全密封免维护托辊,包括有辊筒、轴,以及固定安装在辊筒两端的轴承座,所述的轴承座内设有环形槽,其特征在于:所述的环形槽内壁上由内向外依次安装有与轴配合的轴承、锁紧式轴封、挡圈,所述的锁紧式轴封内孔壁上伸有数层斜环形唇齿与轴过盈联接。
所述的挡圈上设有一个环形分布的凸台。
本实用新型的优点为:
本实用新型的密封性能好,使用寿命长,托辊转动灵活,且托辊无轴向窜动。
附图说明:
图1为本实用新型的结构示意图。
具体实施方式:
下面结合附图说明本实用新型的具体实施方式,参见图1:
全密封免维护托辊包括有辊筒1、轴3,以及固定焊接安装在辊筒1两端的凹槽状的轴承座2,轴承座2内设有环形槽,环形槽内壁上由内向外依次配合有安装与轴上的轴承4、锁紧式轴封5、挡圈6,锁紧式轴封5内孔壁上伸有数层斜环形唇齿与轴3过盈配合,挡圈6内孔圈外侧有轴向延伸凸台,其作用为首次密封。
