弹性金属塑料轴瓦是大型水轮发电机推力轴承的关键性部件，其性能的好坏直接影响到整个系统运行的动态品质。本文通过对金属塑料轴瓦实际模型的压缩性能进行实验研究，发现其压缩弹性模量与巴氏合金轴瓦等金属材料者不同，不是一个固定的常数，而是随着压力的增大，其弹性模量也逐渐地增大。 Flexible metal plastic bearing bush is a key component of large hydrogenerator thrust bearing, the performance of a direct impact on the dynamic performance of the entire system. In this paper, through experiments on the compressive properties of the actual model of the metal plastic bearing bush, it is found that the compressive elastic modulus is different from the metal materials such as the Babbitt bearing bush, which is not a fixed constant, but with the increase of the pressure, The amount is also gradually increased.
