摘　　要：分析了带式输送机改向滚筒表面的受力,以及在不同运行条件下,输送带对改向滚筒表面的作用情况,得出改向滚筒表面在不同输送带张力下的受力情况;通过分析橡胶产生摩擦磨损的过程,得出改向滚筒表面包胶磨损的特点及输送带张力、外界条件等因素对改向滚筒包胶磨损的影响。This paper analyzes, under different operating conditions, the stress which is bore by the redirection roller, obtained under different conveying belt tension roller surface stress characteristics; Through the analysis of rubber friction wear process, we draw some characteristics that the rubber of the surface of redirection roller wears and discover that conveyor belt tension, external conditions are important factors which affect the rubber of redirection drum wear.

关 键 词：带式输送机 改向滚筒 受力 线路布置
