Grinding process of front idler


The grinding of the front idler is a method of processing the front idler wheel when the other metal cutting methods fail to meet the surface accuracy of the front idler wheel. Because this method is very demanding, it is a precision machining process. For manufacturers without experience or technical skills, we do not recommend you to use the grinding process, because it may cause damage to the front idler.


The basic principle of grinding is between the workpiece and the workpiece, or between the grinding tool and the workpiece under a certain pressure and friction, and then cooperate with various abrasives to perform micro-cutting on the workpiece. Generally speaking, the greater the pressure, the more efficient the grinding will be. The higher the pressure is, the more precise the pressure control will be. If the pressure is applied a little, the front idler will be deformed. If the pressure is small, the expected effect will not be achieved. Therefore, mastering the force is the core of the grinding technology.

Analysis of Wear Causes of Front Idler of Excavator

    

Front idler shaft wear and sliding bearing sleeve burnout are caused by the deterioration of the lubrication condition between the front idler shaft and the sliding bearing sleeve, which is caused by the boundary lubrication conversion to a part of the dry friction state. In normal operation, there is a certain gap between the front idler shaft and the plain bearing shaft sleeve and there is an oil film, which forms liquid lubrication. The resulting heat is small and is taken away by the lubricating oil, so that the bearing operating temperature is normal . If the lubricating state of the bearing sleeve and the shaft deteriorates to form a part of the dry friction state, the friction power consumption increases sharply and a large amount of friction heat is generated; when the temperature exceeds  the melting point of the alloy on the surface of the sleeve, the surface of the sleeve starts to melt until it is completely burned
