Abstract

Abstract: The bearing burnout fault was occurred frequently in mill B of boiler No.6 of Tianjin Junliangcheng Power Generation Corporation Limited. The reasons of main bearing burnout of mill were analyzed. Combining with the technical characteristics of rocker style main bearing, the reasons of adopting rocker style bearing were discoursed, and the concrete construction scheme was proposed. The economical efficiency after replacing the mill bearing and before that was compared and analyzed.

Key words: mill, rocker style bearing, scheme, effect
