关节轴^^具有关节轴^的连接结构
技术领域 本发明涉及轴 领域, 更具体地, 涉及一种关节轴 及具有关节轴 的连 接结构。 背景技术 目前一般的关节轴^结构如图 1 所示, 关节轴 10 由外圏 11与内圏 12 组成, 装配时直接将销轴 30打入关节轴^内圏 12 , 其装配结构图如图 2所示, 销轴 30与关节轴承内圏之间为过渡配合。 零件 40与销轴 30连接, 零件 50与 外圏 11连接, 在装配和使用中存在如下问题: 1、 如果销轴 30与关节轴承 10之间配合较紧, 在长期的使用过程中可能 导致销轴 30与关节轴承内圏 12之间产生胶合现象, 使销轴难以拆下, 关节轴 承无法更换与维护;
2、 如果销轴 30与关节轴承 10之间配合较松, 在使用一段时间后, 销轴 30与关节轴^内圏 12之间容易产生相对滑动、 产生异响, 导致销轴 30局部磨 损, 产生凹槽, 使销轴无法拆下, 关节轴 10无法更换与维护;
3、 特别是当图 2所示的 B端区域有障碍物时, 无法从 B端区域施力, 销 轴只能从 A端区域顶出, 此时销轴 30与关节轴承 10如果胶合或磨损, 则销轴 更加无法拆下, 关节轴承无法更换与维护。 发明内容 本发明旨在提供一种关节轴承, 以解决销轴难以从现有的关节轴承中拆卸 等问题。 根据本发明的一个方面, 提供了一种关节轴承, 该关节轴承包括: 外圏与 设置在外圏中的内圏, 还包括轴套, 其中, 内圏套设在轴套外。 进一步地, 轴套为铜套或铝套。 进一步地, 轴套的内壁上设置有润滑油槽。 进一步地, 轴套包括轴向上依次衔接的分体设置的第一段轴套和第二段轴 套,第一段轴套的第一端和 /或第二段轴套的第一端设有卡在内圏端部上的止动 台阶。 进一步地, 止动台阶为圆环形。 进一步地, 第一段轴套的第二端和 /或第二段轴套的第二端设有拆卸槽。 根据本发明的另一个方面, 还提供了一种具有关节轴承的连接结构, 该连 接结构包括: 外圏、 设置在外圏中的内圏、 轴套、 销轴、 第一零件、 第二零件; 内圏套设在轴套外; 第一零件包围轴套的两端; 销轴穿过轴套与第一零件, 连 接轴套与第一零件; 第二零件与外圏连接。 进一步地, 销轴上设有注油孔, 轴套的内壁上设置有润滑油槽, 注油孔与 润滑油槽连接。 进一步地, 轴套包括轴向上依次衔接的分体设置的第一段轴套和第二段轴 套,第一段轴套的第一端和 /或第二段轴套的第一端设有卡在内圏端部上的止动 台阶, 止动台阶夹设在第一零件与内圏之间。 进一步地, 第一段轴套的第二端和 /或第二段轴套的第二端设有拆卸槽。 由于关节轴承釆用轴套, 内圏套设在轴套外, 关节轴承使用时, 可以通过 销轴与轴套之间的间隙配合, 以使销轴容易从关节轴承中拆装, 因而克服了销 轴难以从现有的关节轴 中拆卸的问题。 如果轴套发生磨损, 可以通过更换轴 套而不必更换内圏, 从而保全了关节轴 的内圏, 进而达到了便于销轴更换与 便于关节轴 维护的效果。 附图说明 构成本说明书的一部分、 用于进一步理解本发明的附图示出了本发明的优 选实施例, 并与说明书一起用来说明本发明的原理。 图中: 图 1示出了现有的关节轴承的结构; 图 2示出了现有的具有图 1所示关节轴承的连接结构的装配结构; 图 3示出了根据本发明实施例的关节轴承的结构; 图 4示出了根据本发明实施例的具有关节轴承的连接结构的装配结构; 图 5示出了根据本发明实施例的关节轴承的轴套的侧视结构; 以及 图 6示出了根据本发明实施例的关节轴承的轴套的剖视结构。 具体实施方式 需要说明的是, 在不冲突的情况下, 本申请中的实施例及实施例中的特征 可以相互组合。 下面将参考附图并结合实施例来详细说明本发明。 如图 3所示, 居本发明实施例的关节轴承 10包括: 外圏 11、 设置在外 圏 11中的内圏 12、 以及轴套 60, 其中, 内圏 12套设在轴套 60夕卜, 即轴套 60 设置在内圏 12中。 轴套 60与内圏 12之间可以为过渡配合, 装好后轴套 60与 内圏 12成为一个整体。 如图 4所示, 具有本发明实施例的关节轴承的连接结构包括: 外圏 11、 设 置在外圏 11中的内圏 12、 轴套 60、 销轴 30、 第一零件 40、 第二零件 50; 内 圏 12套设在轴套 60外。 第一零件 40包围轴套 60的两端, 例如, 第一零件 40具有一定的腔体, 将轴套 60夹设在第一零件 40内部。 销轴 30穿过轴套 60与第一零件 40, 连接 轴套 60与第一零件 40。 销轴 30与轴套 60之间例如可以为间隙配合。 第二零 件 50与外圏 11连接, 例如为固定连接。 其中, 第一零件 40、 第二零件 50是关节轴承要连接的两个使用部件, 它 们可以为各种相关的部件, 可以具有各种合适的结构。 工作时, 轴 的外圏 11 与内圏 12之间主要起左右摆动作用, 销轴 30与轴套 60之间进行相对回转运 动。 通过关节轴^ 10的连接, 第一零件 40可以相对于第二零件 50转动。 由于关节轴^ 10釆用轴套 60, 内圏 12套设在轴套 60 夕卜, 关节轴 10 使用时, 可以通过销轴 30与轴套 60之间的间隙配合以使销轴 30容易从关节 轴承 10中拆装, 因而克服了销轴 30难以从现有的关节轴承中拆卸的问题, 如 果轴套 10发生磨损, 可以通过更换轴套 60而不必更换内圏 12 , 从而保全了关 节轴 的内圏 12和销轴 30, 进而达到了便于销轴 30更换与便于关节轴^ 10 维护的效果。 进一步地, 轴套 60为铜套或铝套,销轴 30—般釆用钢制材料制成, 这样, 由于轴套 60的材质硬度较软, 轴套 60与销轴 30的配合中, 轴套 60更容易磨 损, 从而保护销轴 30, 因而, 不会产生由于销轴 30磨损而难以更换销轴的现 象, 便于关节轴^的维护。 此外, 轴套 60 还可以为其他材质较软的金属或合 金制成, 只要硬度低于销轴 30的硬度即可。 进一步地, 如图 4所示, 轴套 60 包括轴向上依次衔接的分体设置的两段 轴套, 即第一段轴套 61和第二段轴套 63。 第一段轴套 61的第一端(图 4中第 一段轴套 61的左端) 和 /或第二段轴套 63的第一端 (图 4中第二段轴套 63的 右端)设有卡在内圏 12端部上的止动台阶 65。 止动台阶 65可以夹设在第一零件 40与内圏 12之间。 止动台阶 65可以起 到限位的作用, 便于第一段轴套 61和第二段轴套 63的装入, 同时还可避免关 节轴 的内圏 12的两侧与零件 40的内侧直接接触而导致的内圏 12的异常磨 损, 可以保护内圏 12 , 增加内圏 12的使用寿命。 优选地, 为了保证第一段轴套 61和第二段轴套 63的止动台阶 65同时卡 在内圏 12的两端, 通常在装配时, 使第一段轴套 61和第二段轴套 63之间具 有一定的间隔。 进一步地, 止动台阶 65为圆环形。 这样, 具有与零件 40的内侧连接的圆 环面, 便于保持和零件 40 的内侧连接的稳定, 也便于装配时从各个方向都能 保证均勾一致的限位作用。 进一步地, 销轴 30上设有注油孔 31 , 如图 6所示, 轴套 60的内壁上设置 有润滑油槽 69 , 注油孔 31与润滑油槽 69连接。 这样, 在关节轴承与使用部件 装配形成具有关节轴 的连接结构后, 通过销轴 30上的注油孔 31可以向具有 关节轴承的连接结构注入润滑油, 加强润滑, 减少磨损, 消除异响。 进一步地, 如图 5所示, 第一段轴套 61的第二端 (即第一段轴套 61上与 止动台阶 65相反的一端 )设有拆卸槽 67或豁口。 拆卸槽 67例如为矩形槽, 其作用是在拆卸第一段轴套 61时, 能够通过在第二端上施加轴向向外的冲力, 以将第一段轴套 61从内圏 12中顶出。 通过拆卸槽 67可以为顶出第一段轴套 61提供施力处, 否则, 由于第一段轴套 61的端部为光滑表面, 没有合适的施 力处, 如果在光滑表面上施加外力, 则会在第一段轴套 61 的端部产生施力的 工具打滑的现象, 对第一段轴套 61从内圏 12中顶出造成较大的困难。 此外, 第二段轴套 63的第二端 (即第二段轴套 63上与止动台阶 65相反 的一端 )也可以具有拆卸槽 67, 其结构和作用与第一段轴套 61的拆卸槽 67相 同。 另外, 第一段轴套 61与第二段轴套 63的结构可以相同, 二者可以互换, 以便制作和安装。 从以上的描述中, 可以看出, 本发明上述的实施例实现了如下技术效果: 本发明提供的关节轴承及相应的连接结构能使销轴易于拆装、 轴承维护方 便, 且能消除轴承异响、 延长轴承使用寿命。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领 i或的技术人员来说, 本发明可以有各种更改和变化。 凡在本发明的 ^"神和原则 之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之 内。
