Description

双向限位过桥轴承 技术领域：
本发明涉及一种轴承， 具体的说是一种双向限位的过桥轴承， 属于机械制造 技术领域。 背景技术：
目前常见的轴承， 按其所能承受的载荷方向可分为： ①径向轴承， 又称向心 轴承， 承受径向载荷。 ②止推轴承， 又称推力轴承， 承受轴向载荷。 ⑧径向止推 轴承， 又称向心推力轴承， 同时承受径向载荷和轴向载荷。 虽然径向止推轴承能 够同时承受径向载荷和轴向载荷，但是其与其它部件的连接方式单一， 且不能起 到双向限位连接的作用。 发明内容：
针对现有技术存在的不足，本发明所要解决的技术问题是， 提供一种双向限 位过桥轴承， 使之能够以多种连接方式将其它与其适配的部件双向限位连接。
为解决上述技术问题，本发明所采用的技术方案是，一种双向限位过桥轴承， 其包括外套、 内套和滚动件， 外套、 内套相适配； 其外套接触内套的侧面上设置 滚槽， 其内套接触外套的侧面上设置凸台； 所述凸台位于滚槽中部， 凸台的两个 侧面分别与相应的滚槽内侧面围成空腔， 滚动件设置在空腔内。
优化的，所述外套由分体的外套 I和外套 Π两部分构成， 外套 I和外套 II相 对面的内角部均设置弧形槽， 外套 I和外套 Π的弧形槽结合成滚槽。
所述滚动件优选滚珠、 滚针或滚子， 也可以是其它滚动承接部件。
所述外套与内套的接触面对齐或不对齐。
所述内套由分体的内套 I和内套 Π两部分构成，内套 I和内套 II相对接触外 套的侧面上整体组合设置凸台。
本发明的有益效果是： 因为使用了滚珠作为滚动件， 所以可以起到双向限位 的作用。 因为轴承内套和轴承外套的接触面既可以对齐， 又可以不对齐， 所以该 轴承与其它部件可以有多种适配方式。 附图说明：
