摘　　要： 高炉罐式炉顶齿轮箱主要故障点是旋转支撑、倾动箱及行星减速机。旋转支撑承受载荷大,通过增加滚动体、均匀内部间隙等措施,优化回转支撑;倾动箱蜗轮齿易局部磨损、蜗轮轴与溜槽挂架易抱死,通过在蜗轮花键轴处增加氮气吹扫与冷却、加强密封、强制干油润滑等,消除了倾动箱故障;行星减速机各轴承因各种杂质形成回转卡阻,通过加设稀油冷却及油过滤装置、及时清理油污等,防止了轴承失效。优化改造后,齿轮箱运行稳定性提高,隐患部位大幅度减少。 Main troubles of the pot-type furnace top gear box were the rotary support, tilting box and planetary reducer. Because of powerful support force, we adopt some measures to improve rotary support： increasing rolling elements, homogenizing internal clearance and so on. Because worm gear of tilting box produced partial abrasion easily and worm shaft with chute rack stuck easily,we adopt some measures to eliminate troubles of tilting box： increasing nitrogen purge and cooling, strengthening seal, enforcing grease lubrication and so on. Because impurities caused each bearing of planetary reducer jamming, we adopt some measures to prevent bearing failure： adding thin oil cooling and filter, cleaning oil stains timely. After these optimization measures, gear box＇s stability raises and hidden parts reduces significantly.
