Abstract

本实用新型属于轴承技术领域，涉及一种外圈无中挡边的四列圆柱滚子轴承，原FCDP结构外圈存在中挡边，滚子与挡边有持续的变应力作用，易使挡边产生应力集中，长时间会发生失效断裂，轴承寿命降低。本实用新型取消了中挡边，由外圈、内圈、滚子、第二滚子、保持架座、保持架盖、中挡圈及外挡圈组成。应力主要集中在外挡圈和中挡圈上，同时增加了滚道长度，延长了轴承的使用寿命。

Description

一种外圈无中挡边的四列圆柱滚子轴承
技术领域
本实用新型属于轴承技术领域，涉及一种外圈无中挡边的四列圆柱滚子轴承，主要应用于冶金行业。
背景技术
轴承在工作中高速运转并受到冲击负荷的作用，现有的FCDP型四列圆柱滚子轴承的外圈存在中挡边，滚子与中挡边有持续的变应力作用，易使中挡边产生应力集中，长时间会发生失效断裂，轴承寿命降低。
发明内容
针对以上不足，本实用新型的目的是提出一种外圈无中挡边的四列圆柱滚子轴承，延长轴承的使用寿命。
本实用新型的技术方案是：一种外圈无中挡边的四列圆柱滚子轴承，它由外圈1、内圈2、滚子3、第二滚子4、保持架座5和保持架盖6组成，外圈1的两个外端面上分别设有外挡圈8，外圈1中间设有中挡圈7，中挡圈7和外挡圈8为活动挡圈。
本实用新型的有益效果是：取消了轴承外圈的中挡边，一方面减少了磨加工工序并极大地降低了磨加工难度，避免了磨加工过程中可能出现的相关磨削裂纹问题；另一方面使应力主要集中在中挡圈7和外挡圈8上，并使滚道长度增加了原有长度的15％以上，使滚子的整体有效长度增加，轴承承载能力随之增强，轴承寿命得到大幅度提高。
附图说明
图1是本实用新型的结构示意图。
图中，1、外圈，2、内圈，3、滚子，4、第二滚子，5、保持架座，6、保持架盖，7、中挡圈，8、外挡圈。
具体实施方式
如附图1所示，本实用新型由外圈1、内圈2、滚子3、第二滚子4、保持架座5和保持架盖6组成，外圈1的两个外端面上分别设有外挡圈8，外圈1中间设有中挡圈7，中挡圈7和外挡圈8为活动挡圈。本实用新型取消了现有FCDP型四列圆柱滚子轴承的外圈的中档边，使应力主要集中在外挡圈8和中挡圈7两个活动挡圈上。
