摘　　要：分析了火电厂筒式钢球磨煤机传动齿轮磨损的机理,介绍了堆焊、热喷涂和润滑处理3种磨损防护方法,结合火电厂的实际应用,根据磨损程度的不同,提出端面换向法、等离子喷涂法、堆焊修复法与高级重负荷工业齿轮润滑油润滑处理配合应用,可较好地解决煤机齿轮磨损问题.This paper analyzed the mechanism of gear wear of barrel-shaped steel ball coal mill, and introduced three methods, such as surfacing, thermal spraying and lubrication to protect the gear from being abraded. According to the different degree of abrasions and the practical using experiences in thermal power plants, this paper introduced how to solve the gear wear problem of coal mill effectively by applying the methods of changing directions at end faces, plasma spraying and surfacing renovation, together with lubrication with advanced heavy load industrial gear lubrication oil.
