Solution for rough surface of front idler axle
There are many metal peaks on the surface of the front idler shaft, which destroys the integrity and continuity of the lubricant film between the shaft and the sliding bearing. During operation, a large amount of metal grinding debris will be generated in the lubricating oil, which will increase the surface roughness of the shaft and the bearing, and the lubrication condition will worsen, causing the front idler shaft and the sliding bearing to be severely worn.
During the wear of the track pins and pin sleeves, the track pitch is gradually extended, resulting in poor meshing between the drive wheel and the pin sleeve, resulting in damage to the pin sleeve and abnormal wear of the tooth surfaces of the drive wheels, which can cause snakes, flaps, and impacts. Greatly shorten the life of the walking mechanism. When the pitch cannot be restored by adjusting the tension, the track pins and pin sleeves need to be turned over to obtain the correct track pitch. At the scene, there are two times when the track pin and pin sleeve are turned over; one method of maintaining the excavator is to check the time when the track pitch is 3mm longer; the other method of maintaining the bulldozer is to check the outer diameter of the pin sleeve At the time of wear of 3mm.
Lubricating oil is injected from the screw hole at the end of the front idler wheel and then gradually fills the entire cavity. In actual operation, if there is no special tool for oil injection, it is difficult for the lubricating oil to pass through the cavity around the front idler wheel only under the effect of its own gravity. And the gas in the cavity is not smoothly discharged, and it is difficult to fill the lubricating oil. The oil filling space of the original machine cavity is too small, causing a serious shortage of lubricating oil.
