%X 针对矿用防爆大功率永磁同步电动滚筒在实际使用过程中隔爆外壳持续承受动态载荷&#65292;从而导致转轴隔爆接合面易发生形变、隔爆性能不稳定等特点&#65292;通过对实际工况进行受力分析&#65292;测算各零部件受力后的位移尺寸链&#65292;并结合有限元分析仿真&#65292;提出了考虑长期径向载荷影响的电动滚筒转轴隔爆面设计方案。本文进一步结合电动滚筒实际运行工况&#65292;提出了隔爆外壳带载状态的隔爆型式试验方法&#65292;并进行了试验验证。最后&#65292;基于本文研制的矿用防爆大功率永磁同步电动滚筒在矿山井下工业性试验中表现良好&#65292;经测量各项隔爆参数正常&#65292;隔爆性能稳定。<br>In view of the flameproof shell of the explosion-proof high-power permanent magnet synchronous electric drum used for mining continues to bear dynamic loads during actual use, which leads to the flameproof joint surface of the rotating shaft being prone to deformation and unstable flameproof performance, the displacement dimension chain of each component under stress is calculated through force analysis of the actual working conditions, and combined with finite element analysis and simulation, the design scheme of flameproof surface of electric drum shaft considering the influence of long-term radial load is presented. In this paper, a flameproof type test method of flameproof shell under load state is proposed and verified by the test. Finally, the explosion-proof high power permanent magnet synchronous electric roller developed in this paper has a good performance in the industrial test in the underground mine, the measured flame-proof parameters are normal, and the flame-proof performance can be stable.
