Abstract

本发明涉及深沟球轴承，具体是一种新型球引导的深沟球轴承，所述轴承包括外圈、内圈、钢球、保持架，保持架由保持架座和保持架盖组成，所述保持架的兜孔为曲面兜孔，保持架座和保持架盖由铆钉铆合成一体后兜孔成椭圆形。本发明轴承实现钢球引导保持架，有利于润滑油脂进入兜孔，增加了兜孔内润滑油脂的存储空间，可以减小半保持架兜孔加工的等分误差。

Description

球引导的深沟球轴承
技术领域
本发明涉及深沟球轴承，具体是一种新型球引导的深沟球轴承。
背景技术
传统深沟球轴承的设计，实体保持架由两半组成，一般采用内引导或外引导的方式，在实际使用中经常出现引导表面磨损现象，容易造成轴承温升高，甚至早期失效。
发明内容
为解决上述技术问题，本发明提供一种新型球引导的深沟球轴承。
为实现上述发明目的，本发明采用以下技术方案：
一种球引导的深沟球轴承，包括外圈、内圈、钢球、保持架，保持架由保持架座和保持架盖组成，所述保持架的兜孔为曲面兜孔，保持架座和保持架盖由铆钉铆合成一体后兜孔成椭圆形。
与现有技术相比，本发明有益效果为：
1）实现钢球引导保持架；
2）有利于润滑油脂进入兜孔，增加了兜孔内润滑油脂的存储空间；
3）可以减小半保持架兜孔加工的等分误差。
附图说明
图1 本发明结构示意图；
图2 本发明保持架结构示意图；a. 右视图；b. 主视图；c. 保持架座和保持架盖合套后的主视图。
具体实施方式
以下结合附图对本发明做进一步说明。
一种球引导的深沟球轴承，包括外圈1、内圈2、钢球3、保持架，保持架由保持架座4和保持架盖5组成，所述保持架的兜孔为曲面兜孔，兜孔的曲率中心在轴向方向上是偏心的，保持架座和保持架盖由铆钉6铆合成一体后兜孔成椭圆形7。
上述深沟球轴承的引导方式为钢球引导，钢球和保持架兜孔的轴向间隙在0.3~0.5mm的范围内，保持架兜孔由传统的直兜孔改为曲面兜孔，并由铆钉铆合成一体形成椭圆形兜孔。
轴承各零件连接方法是：将内圈2放入外圈1中，把钢球3放入外圈1和内圈2之间的空隙中，使钢球3均匀分布，从两侧分别把保持架座4和保持架盖5扣在钢球3上，用铆钉6把保持架座4和保持架盖5联接铆合组成本发明轴承。
