φ2.2×6.5米球磨机系国内60年代的产品,在生产中,常出故障,影响磨机的正常运行,针对存在的问题,我们在结构上作了相应的改进。一、减速器的改进该机原动机功率为380千瓦,选配ZD70—9—Ⅰ型减速器。在运行过程中,用户反映减速器发热,尤其是夏季,温度可达80℃以上。分析原因主要是运行过程中减速器产生的热量与散发的热量不平衡。经计算,该机实需功率357千瓦,ZD70减速器连续工作时产生的热量 φ2.2 × 6.5 m ball mill is a domestic 60’s products in the production, often failure, affecting the normal operation of the mill, for the existing problems, we made the corresponding improvements in structure. First, the improvement of the reducer The engine prime mover power of 380 kilowatts, optional ZD70-9-I-type reducer. During operation, the user reflects the gearbox fever, especially in summer, the temperature can reach above 80 ℃. Analysis is mainly due to the operation of the reducer heat generated and the distribution of heat imbalance. After calculation, the aircraft real power 357 kilowatts, ZD70 reducer continuous work heat generated
