摘　　要：磨煤机承担着火力发电厂动力供应的重要作用,其工作的稳定性直接影响锅炉的出力。磨煤机的正常运行和安装质量密切相关。,本文基于对METSO公司生产的磨煤机的长期安装调试的实践,侧重于磨煤机的关键部件-台板和大齿轮的安装技术研究,提出了合理运用垫铁调整台板的水平度和大齿轮螺栓上不锈钢垫片厚度调整大齿轮轴向窜动的方法,以提高齿轮的啮合效果,为磨煤机的安全、低噪稳定运行提供技术支撑,并且对METSO磨煤机关键设备的初安装和检修工作具有重要的指导意义。In coal power plant, coal mill is an important part of the pulverizing system, which plays a great influence on the boiler outlet and the unit load, the safe operation of coal mill is closely related to the installation quality. In China, there are more than one hundred coal mill made by METSO. Based on the practice of installation and commissioning of coal mill, much attention was paid on the installation techniques of baseplate and large scale gear, the proper procedure and method were put forward by the author. To obtain the minimum error and improve the meshing effect, the horizontal adjustemt by using pad iron and the axial float of large scale gear by adjusting the thichness of stainless steel gaskets on the bolts for large scale gear were performed. All the work had been done provide technical support for safe and low noise operation of coal mill. In addition, all the work had been done is useful for the maintenance of coal mill.
