喀拉通克铜镍矿Φ5.5 m×2.7 m自磨机,出料端轴承部位冒烟,解体检查轴瓦和中空轴,发现出料端的轴颈表面上光洁度有问题,出料端轴颈表面上存在成片的麻点,致使轴颈表面与轴瓦接触面积不够,形成轴瓦面上承载能力不足,接触面上正压力过大,轴与瓦之间的润滑油形不成油膜,成了干摩擦。在轴颈和轴瓦的接触点上造成局部高温,达到了油的燃点发生冒烟。利用打磨的方法解决了缺陷,使设备正常运转。
Kalatongke copper and nickel ore Φ5.5 m × 2.7 m from the mill, the discharge end of the bearing smoke, disintegration check bearing and hollow shaft and found that the discharge end of the journal surface finish problems, the discharge end journal There is a piece of pitting on the surface, resulting in journal surface contact with the bearing area is not enough to form the bearing capacity of the bearing surface is insufficient, the contact surface is too large pressure, the oil between the shaft and the tile can not form a film, became dry friction. In the journal and bearing contact point caused by local high temperature, reached the ignition point of oil smoke. The use of grinding method to solve the defect, so that the normal operation of equipment.
