Description

万向滚珠 技术领域
本发明涉及一种万向滚珠， 尤其涉及一种具有进气通道的万向滚珠。 背景技术
如图 1 所示， 现有的万向滚珠包括： 一本体 100、 一第一滚动体 200、 及设于本体 100与第一滚动体 200之间的数个第二滚动体 300, 本体 100一端设有容置槽 110从而形成容置槽侧壁 112, 该第二滚动体 300可 滚动地设置于容置槽侧壁 112上， 在本体 100另一端设有连接部 120, 该 容置槽侧壁 112在自由端相对延伸设置一挡沿 114以供第二滚动体 300抵 靠。 当该万向滚珠应用于粉尘较多的场合例如玻璃基板切割机时， 粉尘会 掉到第一滚动体 200与挡沿 114之间的缝隙中， 使得第一滚动球 200与第 二滚动球 300之间的滚动摩擦变为滑动摩擦， 增加了摩擦力， 影响了万向 滚珠的使用效果， 且缩短了万向滚珠的使用寿命。 发明内容
本发明的目的在于提供一种万向滚珠， 其可防止粉尘落入其内部， 保 证其使用效果， 且延长使用寿命。
为实现上述目的， 本发明提供一种万向滚珠， 其包括： 一本体、 一第 一滚动体、 及设于本体与第一滚动体之间的数个第二滚动体， 本体一端设 有容置槽从而形成容置槽侧壁， 该第二滚动体可滚动地设置于容置槽侧壁 上， 且本体上设有与容置槽连通的进气通道， 容置槽侧壁对应该进气通道 向外延伸设置抵靠部， 抵靠部的侧面设有出气口。
所述进气通道一端设于本体的侧面， 另一端设于容置槽中心处。
所述出气口均匀设置于抵靠部侧面。
所述出气口为通孔或凹槽。
本发明的有益效果： 本发明所提供的万向滚珠， 其设有与容置槽连通 的进气通道， 进气通道用于通入气体以将容置槽侧壁的异物如粉尘吹掉， 保证万向滚珠的顺利使用， 延长使用寿命。
为了能更进一步了解本发明的特征以及技术内容， 请参阅以下有关本 发明的详细说明与附图， 然而附图仅提供参考与说明用， 并非用来对本发 明加以限制。 附图说明
下面结合附图， 通过对本发明的具体实施方式详细描述， 将使本发明 的技术方案及其它有益效果显而易见。
附图中，
图 1为现有万向滚珠的示意图；
图 2为本发明万向滚珠的立体示意图；
图 3为图 2中的万向滚珠的 A-A向剖视图；
图 4为图 3中 C部分的放大示意图；
图 5为图 2中的万向滚珠的 B-B向剖视图。 具体实施方式
为更进一步阐述本发明所釆取的技术手段及其效果， 以下结合本发明 的优选实施例及其附图进行详细描述。
如图 2-5 所示， 本发明提供一种万向滚珠， 其包括： 一本体 21、 一 第一滚动体 22、 及设于本体 21 与第一滚动体 22之间的数个第二滚动体 23 , 本体 21一端设有容置槽 24从而形成容置槽侧壁 241 , 该第二滚动体 23可滚动地设置于容置槽侧壁 241上， 且本体 231上设有与容置槽 24连 通的进气通道 25 , 容置槽侧壁 241对应该进气通道 25向外延伸设置抵靠 部 26 , 抵靠部 26的侧面设有出气口 261 , 该出气口 261可均匀设置于抵 靠部 26侧面， 该出气口 261可为通孔或凹槽。
该容置槽侧壁 241 在自由端相对延伸设置一挡沿 242 , 该数个第二滚 动体 23排列于该挡沿 242与抵靠部 26之间。
优选地， 该进气通道 25—端设于本体 21 的侧面， 另一端设于容置槽 24中心处。
本发明在工作时通过进气通道 25通入干洁空气（ Clean Dry Air ) 以将 容置槽侧壁的异物如粉尘吹掉， 避免异物卡在缝隙间使万向滚珠的滚动摩 擦变为滑动摩擦而影响使用效果， 从而延长使用寿命。
以上所述， 对于本领域的普通技术人员来说， 可以根据本发明的技术 方案和技术构思作出其他各种相应的改变和变形， 而所有这些改变和变形 都应属于本发明权利要求的保护范围。
