Abstract

本实用新型涉及双列、四列圆柱滚子轴承的内圈,它由外圈、圆柱滚子、保持架和内圈组成,圆柱滚子均布在外圈的滚道,并由保持架分隔支承,内圈一端有径向的凸肩即单挡边,内圈插入圆柱滚子形成的孔内,除承受径向负荷外,也可承受少量的单向轴向负荷。它结构紧凑,径向尺寸小,承载能力高,适用于开式炼胶机和压延机使用。

Description

圆柱滚子轴承
本实用新型涉及双列、四列圆柱滚子轴承的内圈。
目前开放式炼胶机和压延机辊筒支承用铜瓦或尼龙瓦,属于滑动轴承,其接触面大,产生的摩擦也大,能量消耗高,轴瓦使用寿命短,而且生产的产品制造精度低。
本实用新型的目的在于:设计一种能够在承载较大或大的径向负荷的同时,还能够承受少量的单向轴向力的双列、四列圆柱滚子轴承。
本实用新型是这样实现的:它由外圈、圆柱滚子、保持架和内圈组成,圆柱滚子均布在外圈滚道内,并由保持架均匀分隔,内圈一端有径向的凸肩(即带单挡边),内圈插入圆柱滚子形成的孔内,使其上的凸肩(单挡边)紧靠此端的圆柱滚子端面。
本实用新型与现有技术相比具有下列优点:1)由于内圈一端有径向的凸肩,因此能承受少量单向轴向载荷满足主机要求;2)该种结构紧凑,径向尺寸小,适宜于主机选用;3)该轴承内圈可互换,按装拆卸方便;4)主机由原来的轴瓦改为滚动轴承后,摩擦力减小,能耗降低,本品为节能产品;5)主机采用滚动轴承后,提高了辊筒的运转精度,使产品制造精度得到提高。
下面结合附图进行详细说明:
图1为本实用新型四列圆柱滚子轴承剖视图。
图2为本实用新型双列圆柱滚子轴承剖视图;
本实用新型由外圈3、圆柱滚子4、保持架1和内圈2组成,如图1所示,有两个外圈3,其中每个外圈3上有两个滚道,其内分别装入圆柱滚子4,圆柱滚子4由保持架1分隔支承。内圈2一端有径向凸肩5即单挡边,内圈2插入圆柱滚子4形成的孔内,使其上的凸肩5紧靠此端的圆柱滚子4端面。双列圆柱滚子轴承如图2所示,它与四列圆柱滚子轴承结构基本相同,只是圆柱滚子4为双列。
