螺旋线油槽构造销轴

Spiral line oil groove structure pin shaft

Abstract

本实用新型涉及轮式装载机铲斗举升臂连接销轴的改进,是一种螺旋线油槽构造销轴,它设有销轴,销轴上分别设有注油孔及油槽,销轴的注油孔位于销轴的轴端安装有注油嘴,销轴的注油孔延伸至销轴的圆弧面上是与销轴上的油槽连通;特别是:所述的油槽在销轴的圆弧面上是呈螺旋线构造布置,螺旋线构造油槽的轴向两端分别连通有两道环形油槽;本实用新型解决了现有的轮式装载机铲斗举升臂连接销轴所存在的销轴圆弧面的一侧因润滑状况较差容易产生磨损的问题,主要是用于现有的轮式装载机铲斗举升臂连接销轴的改进。
The utility model relates to the improvement of a connecting pin shaft of a lifting arm of a bucket of a wheel loader, in particular to a spiral line oil groove structure pin shaft which is provided with the pin shaft. The pin shaft is provided with an oil filler hole and an oil groove, the oil filler hole of the pin shaft, placed at an shaft end of the pin shaft, is provided with an oil filler port, and the oil filler hole of the pin shaft extends to the arc surface of the pin shaft and is communicated with the oil groove of the pin shaft. The spiral line oil groove structure is characterized in that the oil groove is arranged on the arc surface of the pin shaft in a spiral line structure mode, and two axial ends of the oil groove which is in the spiral line structure are respectively communicated with two annular oil grooves. The spiral oil groove structure pin shaft solves the problem that abrasion happens easily because one side of the arc surface of the pin shaft is bad in lubricating condition in an existing connecting pin shaft of the lifting arm of the bucket of the wheel loader, and is mainly used for the improvement of the connecting pin shaft of the lifting arm of the bucket of the existing wheel loader.
