德兴铜矿f7500×2800自磨机是国内最大的自磨机,经过多年使用,其大、小齿轮均磨损严重,如果全部更新,生产成本将大大增加。自磨机大齿轮材质为 ZG35,重量为61815kg,齿根圆至轮缘内侧的壁厚达175mm,如图1所示。综上原因,为了降低生产成本,保证设备正常使用,对自磨机的大齿轮进行 Dexing copper mine f7500 × 2800 self-mill is the largest self-mill, after years of use, its large and small gear are severely worn, if all the updates, the production cost will be greatly increased. Self-grinding machine gear material for the ZG35, weight 61815kg, the root circle to the rim inner wall thickness of 175mm, as shown in Figure 1. In summary, in order to reduce production costs, to ensure the normal use of equipment, the self-grinding machine gear
