摘要分析了回转窑大齿圈及小齿轮轴密封失效的原因，提出了将轴端密封改为迷宫式挡油圈加石棉盘根压紧密封形式的解决方案，有效防止了润滑油渗漏，大幅降低了润滑成本，避免了缺油造成的齿面损伤。

Abstract: The reason of seal failure of big gear ring and small gear shaft of rotary kiln is analyzed. The solution of changing shaft end seal to labyrinth oil baffle with asbestos packing is put forward, which would effectively prevent the leakage of lubricating oil, greatly reduce the cost of lubrication, and avoid the tooth surface damage caused by lack of oil.

Key words: big gear ring small gear shaft seal transformation
