基于胀套联接结构的传动滚筒静力分析

Static Analysis of Driving Drum based on Expansion Sleeve Coupling Structure

为分析输送带张力对滚筒应力状态的影响,以带式散料输送机某一非标准传动滚筒为研究对象,建立了胀套联接结构形式传动滚筒的有限元分析模型,分别计算了仅考虑自重及胀套胀紧力条件下的应力与同时考虑自重、胀套胀紧力及输送带张力条件下的应力。计算结果显示传动滚筒的筒皮受输送带张力影响最大,其余部件受胀套胀紧力影响较大。

In order to analyze the influence of belt tension on the stress state of a non-standard drive drum of a belt bulk conveyor,a finite element model of a drive drum with expanded sleeve joint structure is established.The stress under the condition of self-weight and sleeve expansion and tightening force and the stress under the condition of self-weight,sleeve expansion and tightening force and belt tension are calculated respectively.The results show that the driving drum is most affected by the tension of the conveyor belt,and the other parts are greatly affected by the expansion and tightening force of the expanding sleeve.
