Abstract

本实用新型涉及一种轧机用双列圆柱滚子轴承,由外圈、内圈、密封环、滚子和弹簧挡圈组成。轴承取消了保持架,在外圈和内圈之间的两边设有密封环。本实用新型的有益效果是,由于取消了保持架,两边又加上了密封,使用寿命提高了5~6倍。

Description

轧机用双列圆柱滚子轴承
技术领域
本实用新型属于轴承技术领域,涉及轧机用双列圆柱滚子轴承,主要应用于轧机粗轧。
背景技术
粗轧机特点是冲击负荷大,转速低,一般四列圆柱滚子轴承是难以接受的,原轧机的粗轧机用四列圆柱滚子轴承均存在寿命短的问题。
发明内容
为适应粗轧机冲击负荷大、转速低的特点,本实用新型的目的提出一种轧机用双列圆柱滚子轴承。
本实用新型的技术方案是,轧机用双列圆柱滚子轴承,由外圈1、内圈2、密封环3、滚子4和弹簧挡圈5组成。该轴承取消了保持架,在外圈1和内圈2之间的两边设有密封环3。
本实用新型的有益效果是,由于取消了保持架,两边又加上了密封,使用寿命提高了5~6倍。
附图说明
图1是本实用新型的轧机用双列圆柱滚子轴承结构装配示意图。
图中,1、外圈,2、内圈,3、密封环,4、滚子,5、弹簧挡圈。
具体实施方式
本实用新型由外圈1、内圈2、密封环3、滚子4、和弹簧挡圈5组成。在外圈1和内圈2之间的两边设有密封环3,取消了保持架,增加了滚子数量,两边又设有密封环3使该轴承能适应粗轧机冲击负荷大、转速低的使用状态。
