Description

具有分体式保持架的深沟球轴承 技术领域
本发明涉及轴承技术领域，尤其是一种具有分体式保持架的深沟球轴承。
背景技术
深沟球轴承中通常设置有保持架，保持架通常装配于内圈和外圈滚道之间，保持架通常具备环状主体结构和沿圆周均匀分布的球兜孔。球兜孔通常采用和球轴承的滚动体类似且曲率半径略大的凹球状面，并且在保持架主体的内径面和外径面分别开口。但是在使用过程中，在急加速或急减速的高速工况下，容易产生较高的温升，使得保持架出现融化裂解，以及保持架在兜孔或者其它位置容易产生冲击断裂，需要关注保持架滚珠的润滑状态，及时对保持架进行补油，但是现有的保持架补油困难，组装也非常不便，降低保持架整体的使用效果，不利于提高生产加工效率。
发明内容
针对现有技术的不足，本发明提供了一种具有分体式保持架的深沟球轴承，其结构简单，整体结构安装便捷，具有更高的稳定性，提高整体结构的使用效果和生产加工效率。
