Abstract

本发明涉及双向限位的过桥轴承，属于机械制造技术领域。能够以多种连接方式将其他与其适配的部件双向限位连接。本双向限位过桥轴承，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。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。

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。③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Ⅱ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Ⅱ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Ⅱ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。
