Abstract

本实用新型提供一种抗冲击角接触球轴承，采用与内部零件等寿命的特殊保持架，以满足抗冲击要求。本实用新型轴承由外圈、内圈、钢球、保持架组成；其中在保持架(1)兜孔(3)的圆柱形表面的外径侧或内径侧加工有环状凸台(2)；钢球直径为轴承径向截面直径的23％～26％；内圈及外圈沟道的曲率半径为钢球直径的0.505倍、0.51倍、0.52倍、0.53倍或0.535倍；内圈与钢球对外圈接触角为20°、30°、36°或42°。本实用新型的保持架具有兜孔锁点，钢球压入兜孔后不掉出，保持架不会损害变形；轴承承载能力大。

Description

抗冲击角接触球轴承
技术领域
本实用新型涉及角接触双列滚动体轴承，具体涉及一种抗冲击角接触球轴承。
背景技术：
轧辊止推部位所使用的角接触球轴承是一种紧凑型双列滚动体轴承，可承受双向轴向负荷，能大幅减小相配轴及轴壳孔轴向尺寸；工作时只承受轴向力，受到轴向冲击很频繁。普通设计的角接触球轴承钢球数量少，承载能力低，且在装配过程中通过凿印的方式锁住钢球，使保持架产生损害变形，影响轴承寿命。
发明内容
本实用新型提供一种抗冲击角接触球轴承，采用与内部零件等寿命的特殊保持架，以满足抗冲击要求。本实用新型轴承由外圈、内圈、钢球、保持架组成；其中在保持架(1)兜孔(3)的圆柱形表面的外径侧或内径侧加工有环状凸台(2)；所述钢球直径为轴承径向截面直径的23％～26％；所述内圈及外圈沟道的曲率半径为钢球直径的0.505倍、0.51倍、0.52倍、0.53倍或0.535倍；所述内圈与钢球对外圈接触角为20°、30°、36°或42°。
本实用新型的保持架具有兜孔锁点，钢球压入兜孔后不掉出，保持架不会损害变形；由于增加钢球量和增大接触角，轴承承载能力增大。
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是保持架结构图；
图2是保持架径向剖视图。
图中：保持架1、环状凸台2、兜孔3。
具体实施方式
本实用新型轴承由外圈、内圈、钢球、保持架组成。如图1、2所示，在保持架兜孔3的圆柱形表面的外径侧或内径侧加工有环状凸台2，使保持架1具有兜孔锁点，钢球压入兜孔3后不掉出，保持架1不易损害变形，与内部其它部件保持等寿命；采取钢球尺寸大小为轴承径向截面直径的23％～26％、内圈及外圈沟道的曲率半径为钢球直径的0.505倍、0.51倍、0.52倍、0.53倍或0.535倍、内圈与钢球对外圈接触角为20°、30°、36°或42°；由于保持架、外圈及内圈结构的改变，轴承承载能力增大。
