Description

一种马鞍形滚动体推力轴承
技术领域
本发明涉及推力轴承，特别涉及一种马鞍形滚动体推力轴承。
背景技术
当前推力轴承结构形式按滚动体形状主要为推力球轴承、推力滚子轴承，推力球轴承优点为在承担一定轴向载荷的同时可以承担少量的径向载荷，缺点是承载能力不高；推力滚子轴承优点为承载能力较大，缺点是不能承担径向载荷且不佳的设计使用容易产生较大边缘应力。
现有技术中推力轴承存在不能同时承载轴向载荷和径向载荷，承载力低和产生边缘应力的问题。
发明内容
本发明为克服现有技术中推力轴承存在不能同时承载轴向载荷和径向载荷，承载力低和产生边缘应力的问题，从而提供一种马鞍形滚动体推力轴承。
本发明的技术方案是：
一种滚动体推力轴承，包括轴圈、座圈、保持架和多个滚动体，所述轴圈和座圈之间设置有保持架，所述多个滚动体安装在保持架上；
所述滚动体为马鞍形曲面回转结构，所述保持架端面加工有多个与滚动体相匹配的兜孔，所述保持架上的兜孔为马鞍形曲面回转结构，所述多个滚动体滚动安装在保持架的兜孔上，兜孔的数量与滚动体的数量对应，所述轴圈的一侧端面设置在多个滚动体一侧的曲面上，所述轴圈与滚动体曲面的接触处加工成圆弧，所述座圈的一侧端面设置在多个滚动体另一侧的曲面上，所述座圈与滚动体曲面的接触处加工成圆弧。
本发明与现有技术相比具有以下效果：
本发明将滚动体设置成马鞍形，轴圈和座圈与滚动体曲面接触处均设计与滚动体相匹配的圆弧结构，该结构轴承可以同时承担轴向和径向载荷，可允许一定的工作偏差，承载能力强且不产生边缘应力。
附图说明
图1是本发明的结构示意图；
图2是本发明剖视图；
图3是本发明滚动体的结构示意图；
图4是本发明保持架的结构示意图；
图5是本发明滚动体安装在保持架上的结构示意图。
具体实施方式
具体实施方式一：结合图1至图4说明本实施方式，本实施方式的一种滚动体推力轴承，包括轴圈1、座圈2、保持架3和多个滚动体4，所述轴圈1和座圈2之间设置有保持架3，所述多个滚动体4安装在保持架3上；
所述滚动体4为马鞍形曲面回转结构，所述保持架3端面加工有多个与滚动体4相匹配的兜孔5，所述保持架3上的兜孔5为马鞍形曲面回转结构，所述多个滚动体4滚动安装在保持架3的兜孔5上，兜孔5的数量与滚动体4的数量对应，所述轴圈1的一侧端面设置在多个滚动体4一侧的曲面上，所述轴圈1与滚动体4曲面的接触处加工成圆弧，所述座圈2的一侧端面设置在多个滚动体4另一侧的曲面上，所述座圈2与滚动体4曲面的接触处加工成圆弧。
具体实施方式二：结合图1至图4说明本实施方式，本实施方式的所述轴圈1另一侧端面的安装孔加工有内螺纹。设置成内螺纹比外螺纹容易安装。其他与具体实施方式一相同。
具体实施方式三：结合图1至图4说明本实施方式，本实施方式的所述座圈2另一侧端面的安装孔加工有内螺纹。设置成内螺纹比外螺纹容易安装。其他与具体实施方式一或二相同。
具体实施方式四：结合图1至图4说明本实施方式，本实施方式所述滚动体4的材质为高温轴承钢。其他与具体实施方式一或二或三相同。
具体实施方式五：结合图1至图4说明本实施方式，本实施方式所述保持架3的材质为塑料。
如此设置是因为保持架3是注塑成型的，保持架3很软，滚动体4用力挤压就可以进入兜孔5内。其他与具体实施方式一或二或三或四相同。
具体实施方式六：结合图1至图4说明本实施方式，本实施方式所述保持架3上兜孔5的个数为10、12或14个。其他与具体实施方式一或二或三或四或五相同。
具体实施方式七：结合图1至图4说明本实施方式，本实施方式所述滚动体4个数为10、12或14个。其他与具体实施方式一或二或三或四或五或六相同。
具体实施方式八：结合图1至图4说明本实施方式，本实施方式：所述保持架3上兜孔5为双凸出锁点马鞍形曲面回转结构。
如此设置可以锁紧滚动体防止从保持架中脱出又可以引导马鞍形滚动体稳定运转。其他与具体实施方式一或二或三或四或五或六或七相同。
本发明已以较佳实施案例揭示如上，然而并非用以限定本发明，任何熟悉本专业技术人员，未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施案例所做的任何简单修改、等同变化与修饰，均仍属本发明技术方案范围。
