摘　　要：通过有限元分析,研究了950开坯机压下系统球面轴承表面正压力的分布情况,并据此提出了相应的改进措施。结果表明:如果将压下螺丝与轴颈的接触位置向外侧移置,可以使球面轴承表面正压力的分布趋向于均匀,从而使最大表面正压力产生明显的下降,使轴承的寿命得到提高。The positive pressure distribution on the bearing surface of screw down system of 950 primary mill was studied using FEM and the corresponding improvement way has been put forward. The results show that if the cantact position of the screw and the roll neck moves out side, the distribntion of the pressure on the bearing surface trends towards even. The largest surface pressure obviously descends ,and the bearing's lifetime increases.
