Abstract

三排圆柱滚子轴承的保持架，属于轴承保持架制造领域。保持架的内径、外径分别镶嵌铜块，保持架两个端面焊接铁块。其有益效果是：保持架内径、外径分别镶嵌铜块用于支撑和引导，保持架两个端面焊接铁块防止保持架翘曲，减少保持架与套圈的摩擦，不影响滚子在套圈中的工作。

Description

三排圆柱滚子轴承的保持架
技术领域    本实用新型涉及三排圆柱滚子轴承的保持架，属于轴承保持架制造领域。
背景技术    盾构机是一种隧道掘进的专用工程机械，用其进行隧道施工具有自动化程度高、节省人力、施工速度快等优点；用于盾构机主轴的三排圆柱滚子轴承尺寸大，立式使用，轴承会出现长轴与短轴，影响轴承正常工作；采用一体式保持架满足轴承立式使用工况的需要，轴承工作时保持架长轴与短轴的差值比轴承套圈长轴与短轴的差值大，短轴处保持架内径、外径极易与套圈的挡边直径接触，增加保持架与套圈摩擦，影响滚子在套圈中的工作。
发明内容    鉴于已有技术存在的缺陷，本实用新型的目的是提供一种三排圆柱滚子轴承的保持架。
为实现上述目的，本实用新型所采用的技术解决方案是：三排圆柱滚子轴承的保持架，其特征在于：保持架的内径、外径分别镶嵌铜块，保持架两个端面焊接铁块。
三排圆柱滚子轴承的保持架，其有益效果是：保持架内径、外径分别镶嵌铜块用于支撑和引导，保持架两个端面焊接铁块防止保持架翘曲，减少保持架与套圈的摩擦，不影响滚子在套圈中的工作。
附图说明
图1是三排圆柱滚子轴承的保持架的局部结构图。
图1附图标记如下：1、保持架，2、铜块，3、铁块。
具体实施方式
在图1出示的三排圆柱滚子轴承的保持架的结构简图中，其主要结构包括：保持架1的内径、外径分别镶嵌铜块2，保持架1两个端面焊接铁块3。
三排圆柱滚子轴承的保持架，保持架1内径、外径分别镶嵌铜块2用于支撑和引导，保持架1两个端面焊接铁块3防止保持1架翘曲，减少保持架1与套圈的摩擦，不影响滚子在套圈中的工作。
