Φ2.4x11中心传动球磨机滑履轴承支承设计 摘 要 球磨机在建材行业应用广泛，是目前工业上广泛使用的细磨机械。磨机能粉末各种硬度的物料，在矿场和发电厂均有应用。球磨机不但在建材工业中广泛应用，而且在冶金、选矿、化工、电力等工业中也广泛采用. 作为粉磨设备的球磨机，目前一般采用滑动轴承作为主轴承，它比传统的支承方式相比具有很大的优势。轴承衬采用巴氏合金，引起具有良好的摩擦相容性、顺应性和嵌入性，非常适合像球磨机这样的重载、低速，并伴有冲击现象的机械设备的要求，因此在生产中已被广泛使用。 关于滑履支承，国外早以在磨机上采用。我国江南水泥厂湿法生料磨机已在进料端采用该支撑方式。由于磨机的大型化发展，其轴承负荷也俞来俞大，另外烘干兼粉磨的磨机，其进料口要大，而且气流温度高，主轴承就不适合，这样，采用滑履支承教为适合。球磨机大型化后, 首先不能满足中空轴的通风面积(尤其是对于带烘干仓的球磨机) , 其次就是传统的进出料螺旋筒不能满足畅通地大量喂料和卸料的要求。本次主要设计滑履支承，并对托瓦、凸球面体、凹球面体等进行工作分析，载荷计算，形状尺寸设计。 关键词：球磨机 滑履轴承支承 分析设计 The design of mill sliding shoe bearings supporting forΦ2.4x11m ball mill ABSTRACT Ball mill in building materials industry at present, it is widely used in industry of fine grinding machine. The function of grinding materials, various hardness powder in the mines and power plants. Only in the building materials industry of ball mill, and widely used in metallurgy, dressing, chemical, electric power industries also widely used As the ball mill grinding equipment, the general sliding bearing as the main bearings, supporting it than the traditional method has great advantages compared. Bearing lining using pasteurized alloy, has a good cause friction compatibility, compliance and embedded, as the ball mill is very suitable for such a heavy load, low-speed and impact of the phenomenon with the requirements of the machinery and equipment, has been in production Widespread use. About sliding shoe supporting, foreign in grinding machine adopts earlier. The wet cement slurry in jiangnan already in the feed mill by the support. Because of the large-scale development of grinding machine, the bearing load is big, the other to yu yu grinding mill and drying machine, its mouth to feed and air temperature is high, the bearing is not suitable, using sliding shoe, such as supporting teaching. After the first large-scale mill, cannot satisfy the hollow shaft ventilated area (especially for the ball with drying, secondly, the traditional) and cannot satisfy the smooth feeding tube feeding a
