摘要
对某进口煤机设备的改向链轮国产化开发后,针对使用过程中出现的铜套磨损严重、润滑油加注困难等问题进行了原因分析,并从设计和使用上提出了改进措施,如改变铜套材料、局部改进改向链轮结构、改变润滑油加注方式等,提高了改向链轮的润滑性能和耐磨性。改进后的改向链轮现场使用180 d后状态完好。
After the localization of the redirection sprocket of an imported coal machine equipment was development, aiming at the problems of serious wear of the copper sleeve and difficulty in filling lubricating oil, carried out the reason analysis, and proposed improvement measures from the design and use, such as changing the material of the copper sleeve, partially improving the structure of the redirection sprocket, changing the way of lubricating oil, etc. Improved the lubrication performance of the redirection sprocket and the wear resistance. The improved redirection sprocket is in good condition after 180 d of field use.
