摘　　要：本文介绍了三峡左岸电站4F、5F、6F、10F、11F机组推力轴承的安装工艺,对12F、13F、14F机组推力轴承安装工艺进行改进。以12F、13F机组推力轴承安装为例,介绍使用改进后的工艺后,各推力瓦温差由原来的4.2℃降为2.9℃、2.1℃,机组运行稳定。This paper presents the 4E 5E 6F, 10F, 11F thrust bearing assembling process of Three Gorge left bank units, and introduces an improved technic on the 12E 13E 14F thrust bearing assembling. The 12E 13F thrust bearing, for example, have been erected by the new method and the temperature difference of thrust pads has been decreased from original 4.2℃ to 2.9℃ and 2.1℃, and so that the unit is operating stably.
