Abstract

本实用新型公开了一种圆锥滚子轴承，由外圈（1）、保持架（2）、滚子（3）和内圈（4）组成，内圈（4）大挡边结构为凸圆弧内圈大挡边结构。本实用新型的一种圆锥滚子轴承，将现有圆锥滚子轴承锥形内圈大挡边结构或凹圆弧形内圈大挡边结构改进为凸圆弧内圈大挡边结构，在无载荷状态下为点接触，在载荷作用下为面接触，减少摩擦，提高轴承旋转速度和轴承寿命，降低轴承能量损失。

Description

圆锥滚子轴承
技术领域
本实用新型属于轴承技术领域，尤其涉及一种圆锥滚子轴承。
背景技术
目前圆锥滾子轴承内圈大挡边有锥形和凹圆弧形两种结构，在轴承旋转时分别存在应力集中和摩擦大等缺陷。
发明内容
本实用新型的目的是提供一种消除应力集中，减少摩擦的圆锥滚子轴承。
本实用新型为实现上述目的所采用的技术方案是：一种由外圈（1）、保持架（2）、滚子（3）和内圈（4）组成，内圈（4）大挡边结构为凸圆弧内圈大挡边结构。
本实用新型的一种圆锥滚子轴承，将现有圆锥滚子轴承锥形内圈大挡边结构或凹圆弧形内圈大挡边结构改进为凸圆弧内圈大挡边结构，在无载荷状态下为点接触，在载荷作用下为面接触，减少摩擦，提高轴承旋转速度和轴承寿命，降低轴承能量损失。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步说明。
图1是现有圆锥滚子轴承锥形内圈大挡边结构示意图。
图2是现有圆锥滚子轴承凹圆弧形内圈大挡边结构示意图。
图3是本实用新型圆锥滚子轴承结构示意图。
图4是本实用新型圆锥滚子轴承凸圆弧内圈大挡边结构示意图。
图中：1、外圈；2、保持架；3、滚子；4、内圈。
具体实施方式
如图1和图2所示，现有的圆锥滚子轴承的内圈大挡边结构为锥形内圈大挡边结构或者凹圆弧形内圈大挡边结构，这种内圈结构的圆锥滚子轴承在旋转时存在应力集中和摩擦较大的缺陷。如图3和图4所示，本实用新型的圆锥滚子轴承，由外圈1、保持架2、滚子3、内圈4组成，本实用新型针对滚子3大端面与内圈4大挡边接触部位进行改进，将内圈4大挡边结构改进为凹圆弧内圈大挡边结构，这种内圈大挡边结构在无载荷状态下为点接触，在载荷作用下为面接触，减少摩擦，提高轴承旋转速度和轴承寿命，降低轴承能量损失。
