Excavator bushing is one of the consumable parts of excavator,
there are many styles of bushing, so it becomes necessary
to choose the right bushing.
There must be a lubricating oil groove on the inner wall of the bushing.
The lubrication of the bushing is very important.
1.Figure 1 shows the deep oil tank bushing.
2.Figure 2 shows the graphite bushing.
3.Figure 3 shows the point bushing flange bushing of excavator.
If there is no oil tank to add lubricating oil to dry the bucket shaft and bushing,
the bucket shaft and the bucket bushing will soon be damaged or even
broken and deformed due to excessive heat, which will reduce the
impact on the service life of the excavator. Due to the large amount
of excavator working environment Dust and sand will easily enter the
gap between the bucket shaft and the bushing, which will cause abnormal
noise of the excavator bucket and accelerate the wear of the bucket shaft and bushing.
Therefore, it is necessary to add lubricant to the bushing regularly to extend the bucket.
The use time of the shaft and the bushing increases
the working efficiency of the excavator,
