摘 要
爐頂旋轉布料溜槽傳動齒輪箱是大型煉鐵高爐極為重要的部件，它的運行狀況直接關系到高爐煉鐵生產的安全、正常進行。盡管該設備部件在設計時考慮得比較細致、周全，使用單位還不斷加大檢修力度，但是在使用過程中仍然難免發(fā)生意外故障甚至嚴重事故。生產實踐表明，有必要對旋轉溜槽傳動齒輪箱進行運動故障仿真，對生產過程中會發(fā)生的故障進行診斷，防患于未然，并給維修提供正確的信息，提高經濟效益。
本文通過分析高爐布料齒輪箱的結構特點和傳動關系，研究了布料溜槽在轉動而不傾動、傾動而不轉動、同時轉動和傾動等情況下的運動特性。利用ADAMS軟件建立了布料溜槽傳動系統(tǒng)的虛擬樣機模型，在虛擬樣機基礎上進行了各種傳動形式的運動學仿真。根據布料溜槽運動特征及驅動電機的動力特征分析了在各種條件下的運動征兆，為故障點的評判與確定提供依據，再結合機組的運行工況、歷史資料及專家的經驗知識對故障發(fā)生的部位做出準確判斷，以縮短維修時間。

ABSTRACT
The transmission gearbox of distributor chute on BF top is a key equipment of iron plant.It’s condition concern the normal production of iron-smelting directly .Although the design of the equipments is very careful and the overhaul is getting stronger ,the accidental fault is still unavoidable. The production practices is showing that It is essential for gearbox to Fault simulation campaign. By analysing the signal , We can prevent trouble before it happened and change maintaining regularly into foreseeing maintaining.
This article through the analysis blast furnace cotton material gear box's unique feature and the transmission relations, has studied the cotton material chute, in rotation, but not preferential motion, preferential motion but does not rotate, simultaneously rotates and situation and so on in preferential motion cotton material characteristics. Has established the cotton material chute transmission system's dummy specimen model using the ADAMS software, has carried on each transmission form kinematics simulation in the dummy specimen foundation. And actuated electrical machinery's dynamic characteristic according to the cotton material chute movement characteristic to analyze under each kind of condition movement indication, provided the basis for the fault point judgment and the determination, the recombination unit's operating condition, the historic information and the domain expert's experience knowledge the spot which occurred to the breakdown makes the accurate judgment

Key words：Gearbox ，F(xiàn)ault diagnosis ，ADAMS , Simulation
