钢球煤磨机结构设计摘 要钢球磨煤机用于干式粉磨各种硬度的煤炭之用，本机器用于热电厂加工固定燃料——煤粉，是热电厂制粉系统中主要设备，它只有借助于热风（热风温度不得超过300℃）的干燥和运输，才能良好的工作，当煤粉细度可磨性系数变化时，机器出粒相应修改。本次煤磨机的结构和原理设计来源于生产实际，因此，依照经济、高效、操作方便等原则，除对煤磨机的总体结构进行优化设计，主要包括传动装置和回转装置的设计。由于主要参数的设计和制定对机器本身的影响很大，所以在煤磨机原理设计方面，主要针对参数设计进行了探讨。在完成设计任务的同时，画出传动装置和回转装置的装配图、煤磨机总图、齿圈和端盖零件图。。关键词：轴承部 传动部 转速 功率 筒体应力 Design of ball coal mill sectorABSTRACTBall mill for dry grinding of coal use in a variety of hardness, the machine used for processing fixed-fuel thermal power plants - coal is the major thermal power plant equipment, milling system, it is only by means of hot air (air temperature must not exceed 300 ℃) dry and transport to the good work, when the fineness of grinding coefficients change, the machine out of tablets amended accordingly. The coal mill structure and principle of design from production practice, therefore, in accordance with the economic, efficient and convenient operation principles, in addition to the overall structure of the coal mill to optimize the design, including gear and the rotary device. As the main parameters of the design and development of a significant impact on the machine itself, so in principle the design of coal mill, the main design for the parameters discussed. Complete the design task in the same time, draw gear, and rotating equipment assembly drawings, general layout of coal mill, ring gear and the end cap part drawing.
