应用有限元程序分别对圆形瓦和扇形瓦推力轴承在中心支承条件下的性能进行了计算。并根据计算结果对两种瓦形的轴承性能作了比较。其结果和实验结论比较一致。最后得出圆形瓦轴承比扇形瓦轴承在某些方面有一定的优越性。 The finite element program was used to calculate the performance of circular and fan-shaped thrust bearings under the condition of central support. According to the calculation results, the bearing performances of the two kinds of tile are compared. The result is consistent with the experimental conclusion. Finally, the conclusion is that circular tile bearing has some advantages over fan-shaped tile bearing in some aspects.
