摘　　要：基于对现行带式输送机托辊的使用工况及结构特点的分析和研究,提出了托辊使用寿命短的原因,得出了其失效破坏形式主要是密封设计不合理,因而造成轴承产生极度磨损和锈蚀,不能灵活运转。认为可靠有效的密封是提高托辊寿命最有效最经济的途径,介绍了高效长寿命的密封设计方法。Based on the research and anaylsis of the working condition and structure features in current conveyor, the reason of low life in use was pointed out. Then the unreasonable seal design was the damaged form of failure, extreme wear and rust in bearings was caused. Efficient and long life＇s seal design was put forward. Using reliable and efficient seal design was the most economical way to increase bearings＇ life expectancy, the conveyor＇s operating costs was reduced greatly.
