这种布置有若干缺点, 包括: 梅花圏和垫片较为昂贵, 没有减震作用 等。
为此, 需要一种改进的电机外壳与轴承的布置。 实用新型内容
在本实用新型的一个方面, 提供了一种轴承套, 该轴承套用于放置在 外壳中, 并包括: 用于放置轴承的内孔。
根据本实用新型的实施例, 该轴承套为塑料制成。
根据本实用新型的实施例, 该轴承套还包括一封闭的端部。
根据本实用新型的实施例, 该轴承套上还设置有用于与外壳周向固定 的固定装置。
根据本实用新型的实施例, 所述固定装置为轴承套端部的凸出部分, 所述凸出部分用于与外壳上的凹陷部分形状配合, 从而将轴承套与外壳周 向固定。
根据本实用新型的实施例, 所述凸出部分包括圆周上的若干凸耳, 所 述凸耳用于与外壳上的凹陷部分的相应凹坑形状配合, 从而将轴承套与外 壳周向固定。
根据本实用新型的实施例, 所述轴承套的圆周壁上有若干纵向槽, 从 而在圆周上形成若干纵向爪。
根据本实用新型的实施例, 在该轴承套的一端设置有用于与外壳定位 的突出部。
根据本实用新型的实施例, 所述内孔的表面为球面, 以用于放置球面 轴承。
根据本实用新型的实施例, 该轴承套用于汽车座椅用电机中。
在本实用新型的另一个方面, 还提供了一种电机, 该电机包括: 外壳; 轴承; 以及根据上述任何一个实施例的轴承套; 其中, 该轴承套放置在外 壳中, 该轴承放置在该轴承套中。
根据本实用新型的实施例, 该电机为汽车座椅用电机。
本实用新型的一个或多个实施例具有如下一个或多个优点:
价滅廉;
省去了用于减少轴承与外壳之间的摩擦和磨损的垫片,省去了梅花圏, 从而节省了成本并简化了结构;
塑料轴承套可以在一定程度上减震。 附图说明
图 1示出了现有电机中外壳与轴承的布置;
图 2示出了根据本实用新型的实施例的轴承套的透视图;
图 3示出了根据本实用新型的实施例的轴承套的另一个透视图; 图 4示出了根据本实用新型的实施例的轴承套与外壳的布置; 以及 图 5 示出了根据本实用新型的实施例具有与轴承套配合的结构的外 壳。 具体实施方式
现参照附图描述本实用新型的实施例。 应指出的是, 尽管在以下描述 中包含了大量细节, 但这些细节仅是示例性的, 而不是对本实用新型的限 制。 本实用新型的特定实施例中, 可以不包含其中一些细节。
图 2示出了根据本实用新型的实施例的轴承套的透视图。 图 3示出了 根据本实用新型的实施例的轴承套的另一个透视图。 图 4示出了才艮据本实 用新型的实施例的轴承套与外壳的布置。 图 5示出了才艮据本实用新型的实 施例具有与轴承套配合的结构的外壳。
如图所示, 在本实用新型的一个方面, 提供了一种轴承套 3, 该轴承 套 3用于放置在外壳 1中, 并包括: 用于放置轴承 4的内孔 5。 也就是说, 该轴承套 3置于外壳 1与轴承 4之间。
根据本实用新型的实施例, 该轴承套 3为塑料制成。 当然, 在本实用 新型的其他实施例中, 该轴承套 3也可以为其他材料制成, 例如其他塑性 材料, 或诸如金属等刚性材料制成。 由塑料或其他塑性材料制成的轴承套 可具有一定程度的减震功能。 所述塑料或其他塑性材料优选为耐热材料。
根据本实用新型的实施例, 如图 3所示, 该轴承套 3还包括一封闭的 端部 6。 也就是说, 在该轴承套 3与外壳 1壁接触的一端为封闭的, 而另 一端为敞开的, 以便放置轴承 4。 由于所述轴承套 3的封闭的端部 6可将 轴承 4与外壳 1壁分隔开, 这样, 就不再需要现有技术中的垫片。
根据本实用新型的实施例, 该轴承套 3上还设置有用于与外壳周向固 定的固定装置, 以防止在轴的旋转过程中轴承套 3的旋转。 通过使用带有 固定装置的轴承套 3, 可以将轴承 4固定在外壳 1上, 这样就不再需要现 有技术中的梅花圏 2, 从而节省了成本。
根据本实用新型的实施例, 所述固定装置为轴承套端部 6的凸出部分 7,所述凸出部分 7用于与外壳 1上的凹陷部分 8形状配合,从而将轴承套 3与外壳 1周向固定。 例如, 该凸出部分 7为从端部突出且小于端部外廓 的非圆形 (例如三角形) 凸出部分 7, 该非圆形凸出部分与外壳 1壁上相 同形状的非圆形凹陷部分 8相配合, 以将轴承套 3周向固定在外壳 1上。
根据本实用新型的实施例, 如图 3所示, 所述凸出部分 7包括圃周上 的若干凸耳 9, 所述凸耳 9用于与如图 5中所示的外壳 1上的凹陷部分 8 的相应凹坑 10形状配合, 从而将轴承套 3与外壳 1周向固定。
根据本实用新型的实施例, 如图 2和 3所示, 所述轴承套 3的圆周壁 上有若干纵向槽 11,从而在圆周壁上形成若干纵向爪 12。与整体圆筒形的 圆周壁相比, 由纵向槽 11和纵向爪 12构成的圆周壁结构更为轻巧, 且节 省了材料和成本。
根据本实用新型的实施例, 如图 2所示, 在该轴承套 3的一端设置有 用于与外壳 1定位的突出部 13。 也就是说, 在轴承套 3的与外壳 1壁接触 的一端 6的相对端上设置有用于与外壳定位的突出部 13。在轴承套 3包括 纵向爪 12的本实用新型的实施例中, 该突出部 13位于一个所述纵向爪 12 上。 该突出部 13便于在将轴承套 3安装在外壳 1上时正确地将轴承套 3 与外壳 1周向定位。
根据本实用新型的实施例, 所述内孔 5的表面为球面, 以用于放置球 面轴承。在轴承套 3包括纵向爪 12的本实用新型的实施例中,每一个纵向 爪 12的内表面均为球面的一部分。
根据本实用新型的实施例,该轴承套 3用于汽车座椅用电机中。 当然, 根据本实用新型的实施例的轴承套 3也可以用于其他电机中, 或用于其他 包含轴承的装置中。
在本实用新型的另一个方面, 还提供了一种电机, 该电机包括: 外壳 1; 轴承 4; 以及根据上述任何一个实施例的轴承套 3; 其中, 该轴承套 3 放置在外壳 1中, 该轴承 4放置在该轴承套 3中。
根据本实用新型的实施例, 该电机为汽车座椅用电机。
以上参照附图描述了本实用新型的实施例, 应指出的是, 以上描述仅 为示例, 而不是对本实用新型的限制。 通过以上描述, 本领域技术人员可 以做出很多修改和变形, 而不超出本实用新型的精神和范围。 本实用新型 的范围仅由所附权利要求限定。
