Static Analysis of Drive Roller Based on Interference Amount of Expansion Sleeve

传动滚筒是带式输送机的重要组成部件，其主要作用为传递功率。为分析带与滚筒之间摩擦力对胀套过盈联结滚筒所受应力的影响，以某一带式输送机非标滚筒为研究对象，根据胀套过盈计算建立有限元模型，基于有限元过盈配合理论分别对未工作无相对运动趋势的滚筒及工作有摩擦力的滚筒进行有限元计算，计算结果显示轴受带与滚筒间摩擦力的影响最大。The drive drum is a critical component of a belt conveyor, primarily responsible for transmitting power. To analyze the influence of friction between the belt and the drum on the stresses in the shrink-fit bushing interference fit of the drum, a non-standard drum from a specific belt conveyor was selected as the research subject. A finite element model was established based on shrink-fit interference calculations, and finite element analyses were conducted using interference fit theory for two scenarios: the drum in a non-operational state without relative motion tendencies, and the drum under operational conditions with friction. The results demonstrate that the shaft is most significantly affected by the friction between the belt and the drum.
