| 摘 要： | 为了适应球磨机大型化的发展趋势,开发了MQY6095型球磨机。针对该球磨机的结构特点,用有限元方法计算得到了回转部的整体应力和变形,然后在中空轴处施加支撑力,计算中空轴和端盖圆角处的应力,最后用计算流体动力学方法计算得到了轴承油膜的压力分布和速度分布。现场应用表明,分析结果与实际观测值吻合得很好,说明该设计方法有效地保证了球磨机设计的可靠性。

| Abstract: | To adapt to the large-scale development trend of ball mills,MQY6095 ball mill has been developed.In the paper,based on the structural characteristics of the ball mill,stress and distortion of the rotary body are computed using FEM,and then the stress at the round corner of the end cover and the quill shaft are calculated by applying radial force to the quill shaft.Lastly the pressure distribution and the velocity distribution of the oil film of the bearing are calculated with computing fluid dynamics method... |
