Description

一种防漏油的自润滑减速机 技术领域
本发明涉及减速机领域，具体涉及一种防漏油的自润滑减速机。
背景技术
在减速机领域中，对于高速运转的减速机，由于转轴转速较大，轴承的发热量大，需要油润滑及透气帽透气降温。现有的较常见的润滑方式为自润滑，即由齿轮在转动过程中将油甩出，将甩出的油收集后导向轴承进行润滑。这样的润滑方式通常存在的缺陷是，由于轴承也是在高速转动，轴承会将润滑油向轴端甩出并从轴承端盖处的油封溢出，造成污染。同时部分甩出的油容易自透气帽内溅出，造成污染和浪费。
发明内容
为解决现有技术中的不足，本发明的目的在于提供一种防漏油的自润滑减速机。
本发明采取的技术方案为：
一种防漏油的自润滑减速机，包括箱体、箱盖和多根转轴，转轴穿接于箱体，箱盖安装于箱体的顶部，所述箱体的前、后箱壁上均设有轴承孔，轴承孔内安装有轴承，箱体的外壁上安装有覆盖轴承孔的轴承端盖，转轴的两端支承于轴承内孔并穿接轴承端盖，转轴与轴承端盖间经油封密封，转轴上安装有齿轮，所述箱盖的内壁上设有集油槽，集油槽的底部设有通向轴承孔的通道，所述轴承孔内设有挡油板，所述挡油板串接于转轴，挡油板设置于轴承与轴承端盖之间，所述箱盖的侧壁的上部设有弯管透气帽。
进一步地，所述透气帽包括弯管和帽体，弯管竖直安装于箱盖侧壁的上部，帽体安装于弯管的顶部，所述帽体的内侧设有联通弯管及外侧的曲线通道。
再进一步地，所述弯管内设有一道以上的挡板，多道挡板在弯管内形成折线通道，所述挡板的底面上设有间隔的隔挡。
采取以上技术方案后，本发明的有益效果为：
1.轴承端盖、轴承机轴承孔形成一个腔体，通过自润滑的方式将油导引进腔室内对轴承润滑，为避免轴承甩油溢出，在轴承与轴承端盖间设置挡油板，将轴承的甩油遮挡，有效避免外泄；
2.采用弯管式透气帽，相对直管而言弯管为弯曲通道，弯管的内侧设有多个挡板，挡板在弯管内形成折线通道，挡板的底面上设有隔挡，当有溅至挡板时，隔挡有个起到缓冲和导向作用，避免有的反射和飞溅；以上技术方案结合能够更有效地避免润滑油的溅出。

图2为本发明弯管透气帽结构示意图。
