摘　　要：对引起带式输送机跑偏故障的原因进行归纳总结,并采用ADAMS对调心托辊纠偏特征进行模拟分析。研究表明:(1)带式输送机跑偏故障是输送带受力不均衡、托辊及滚筒故障等多因素综合作用结果。(2)调心托辊在偏转12°以内时具有较强的纠偏能力,但是偏转超过12°后纠偏能力呈显著降低趋势。(3)在带式输送机现场应用时,应将输送带跑偏量控制在较小范围内,当跑偏量较大时应采用人工辅助纠偏方式降低输送带跑偏量,从而降低输送带跑偏影响。研究成果可为矿井带式输送机跑偏故障的处理及预防提供一定借鉴。The causes of conveyor belt misalignment are first analyzed and summarized,and a simulative study is conducted of the correction performance of ADAMS self-aligning idler rolls. The study reveals that:( 1) Belt conveyor misalignments occur as a result of a number of factors,including: imbalanced belt load,mal-functionary idlers and pulleys.( 2) The correction performance of selfaligning idlers is quite strong when their flip is within 12°,but declines notably when the flip is greater than 12°.( 3) In field application,therefore,belt misalignment should be controlled within a small range. When the misalignment is great, human interference is required to limit the misalignment impact. The study can serve as a useful reference for the handling and prevention of belt conveyor misalignments in mine shafts.
