摘　　要：分析离心压缩机组止推轴承瓦温高的原因,通过计算联轴节的预拉伸量,使膜片热态下的变形最小,根据实际情况增加或减少联轴节预拉伸量,以保证其轴承瓦温在正常范围。The reasons for high temperature occurred on thrust bearing bush in centrifugal compressor were studied. To get the minimum deformation of membrane under heat condition, the pre-tensioning strength on coupling should be calculated, which might be increased or decreased according to practical conditions to assure the bush temperature in a normal range.

关 键 词：止推轴承 瓦块温度高 联轴节膜片 预拉伸量
