The PC100 front idler is composed of a guide wheel, a 0-shaped seal ring, a PC100 front idler plug plate, a cylindrical pin, a PC100 front idler body, an iron sleeve, and a bimetallic sleeve. The PC100 front idlers are installed at the front of the trolley frame, and are used to guide the running direction of the track and keep the track tight with the help of the buffer device to reduce the runout of the track in operation, thereby reducing the impact load and additional power loss, and Prevent track derailment.

Cause of damage of PC100 front idler assembly


The cause of damage to the PC100 front idler assembly is mainly caused by poor lubrication of the PC100 front idler shaft. The reasons are as follows:

 

1. It is the difference between the biaxial sleeve bearing of the PC100 front idler that has different axial degrees, and the track walking generates vibration and impact. Once the geometric size is too poor, the gap between the PC100 front idler shaft and the sleeve is too small or no gap, and the thickness of the lubricant film is not enough No lubricant film.


2. the surface roughness of the PC100 front idler axle is extremely poor. There are many metal peaks on the shaft surface, which destroys the integrity and continuity of the lubricant film between the shaft and the sliding bearing. During work, 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 serious wear of the PC100 front idler shaft and the sliding bearing.


3. there is a defect in the original structure. Lubricating oil is injected from the screw plug hole at the end of the PC100 front idler, 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 PC100 front idler only by its own gravity, and The gas in the cavity is not discharged smoothly, 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.


4. It is because the lubricating oil in the gap between the wheel shaft and the sleeve is unable to take away the heat generated by the work of the bearing because there is no oil passage, which causes the bearing's operating temperature to rise, the viscosity of the lubricating oil, and the thickness of the lubricating oil film to decrease.
