Description

单向旋转深沟球轴承
技术领域
本实用新型涉及一种单向旋转深沟球轴承。
背景技术
深沟球轴承适用于高转速甚至极高转速的运行，而且非常耐用，无需经常维护。该类轴承摩擦系数小，极限转速高，结构简单，制造成本低，易达到较高制造精度。尺寸范围与形式变化多样，应用在精密仪表、低噪音电机、汽车、摩托车及一般机械等行业，是机械工业中使用最为广泛的一类轴承。主要承受径向负荷，也可承受一定量的轴向负荷。
在一些领域需要用到单向轴承，而普通的单向轴承承载能力有限，没有深沟球轴承高极限转速、低摩擦系数等优点，因此，提供一种单向旋转深沟球轴承是本领域所要解决的技术问题。
发明内容
本实用新型所要解决的技术问题是提供一种结构简单、极限转速高的单向旋转深沟球轴承。
为解决上述技术问题，本实用新型提供了一种单向旋转深沟球轴承，其包括：内圈、第一外圈、设于内圈与第一外圈之间一侧的数个钢球、设于钢球外侧的第一保持架、设于第一保持架外侧的密封圈、设于内圈与第一外圈之间另一侧的数个滚子、设于滚子与第一外圈之间的第二外圈、设于滚子外侧的第二保持架、设于第二保持架上用于抵住滚子的弹簧。
所述第二外圈的内侧设有用于限位滚子的多个契形槽，所述契形槽由半径不同、弧度不同的三个弧度段构成，第一弧度段半径小、弧度小，因此坡度较深，第二弧度段半径较大、弧度较大，因此坡度较平，第三弧度段的半径即为第二外圈无契形槽时的内半径，弧度可根据契形槽数量调整，在弹簧的配合下，契形槽用于限位滚子，使滚子只能单向旋转，逆向旋转时被卡住。
本实用新型的技术效果：本实用新型所述的单向旋转深沟球轴承，在原深沟球轴承的基础上进行了单向旋转的改进，因而具备深沟球轴承高极限转速、低摩擦系数等优点，而且该轴承具备良好的限位能力。
附图说明
为使本实用新型能更清楚的被理解，下面结合附图和具体实施例对本实用新型作进一步详细说明：
图1是本实用新型所述的单向旋转深沟球轴承的结构示意图；
图2是第二外圈的结构示意图；
图3是图2的局部放大图。
具体实施方式
如图1-3，本实施例的单向旋转深沟球轴承包括：内圈1、第一外圈2、设于内圈1与第一外圈2之间一侧的数个钢球3、设于钢球3外侧的第一保持架4、设于第一保持架4外侧的密封圈5、设于内圈1与第一外圈2之间另一侧的数个滚子6、设于滚子6与第一外圈2之间的第二外圈7、设于滚子6外侧的第二保持架8、设于第二保持8架上用于抵住滚子的弹簧9。
所述第二外圈7的内侧设有用于限位滚子的多个契形槽7-1，所述契形槽7-1由半径不同、弧度不同的三个弧度段构成，第一弧度段半径为r1=1.7±0.05mm、弧度为α=3.5°，因此坡度较深，第二弧度段半径为r2=37.2±0.05mm、弧度为β=11°，因此坡度较平，第三弧度段的半径即为第二外圈无契形槽时的内半径，为r3=38±0.05mm，弧度γ=8°, γ可根据契形槽数量调整，在弹簧的配合下，契形槽7-1用于限位滚子，使滚子只能单向旋转，逆向旋转时被卡住。
显然，上述实施例仅仅是为清楚地说明本实用新型所作的举例，而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而这些属于本实用新型的精神所引伸出的显而易见的变化或变动仍处于本实用新型的保护范围之中。
