摘要：目前，機立窯存在二大技術和工藝難點：一是立窯煅燒熱工不穩，嚴重影響水泥各項物理性能；二是立窯單窯產量低，不能適應當今各行各業的發展形勢。因此，JLY3809機立窯在這種情況下應運而生。而機立窯的傳動裝置在機立窯的整體結構中起到極其重要的作用。在對生產現場全面調研的基礎上，對生產現狀進行了有效分析，確定了傳動裝置的總體設計方案。為了提高水泥生產中機立窯的傳動效率，滿足生產工藝和生產量的需求，應用最優化方法，確定速比係數的分配，大、小齒輪的設計。設計了軸的結構，進行了軸的強度校核計算。確定了機立窯轉速，選擇合理的潤滑形式。另外，大立軸是傳動的主要部分，帶動塔篦子低速轉動，承受巨大的載荷，是保證機立窯正常工作的關鍵,因此需要有高的可靠性、良好的穩定性和合理的經濟性。通過幾種方案的比較，軸承的選擇採用了最優的設計方案，從而增加機立窯的傳動平穩性和使用壽命，大大提高了機立窯運轉率。機體工作運行平穩，安裝維修方便。

The overall and transmission device design of 3809 mechanical upright kiln
Abstract: There are two main difficulties of mechanical upright kiln presented both on technology and on process. First, the hot working of the kiln is unsteady, which seriously affects the physical performance of the cement; second, the output of the single kiln is low, which cannot adapt to the intensified development situation in various professions. As a result, 3809 mechanical upright kiln is appeared in this situation. The transmission device plays a vital role in the whole configuration of the kiln. On the basis of comprehensive investigation and study, the present production situation has been analyzed and the transmisson device has been designed in order to enhance transmission efficiency of the kiln in the cement production, satisfy meet production process and productivity demands. By using optimization method, the definite transmission ratio,ball gear and pinion gear have been designed at first.Then the axis structure and intensity examination computation have been completed too. After determining the kiln rotational speed, chooses the reasonable lubrication form. Moreover, the large vertical spindle is the main part in the transmission, it impetuses the cone type to discharge grate at a low speed and withstands huge load, which is the key to ensure the normal work of the kiln. This calls for high reliability, good stability and reasonable economical efficiency. By comparing several plans, the optimization method was confirmed on the choice of bearing, thus increases the transmission stability and the service life of the kiln, enhancing the kiln operating efficiency greatly.It is smooth and reliable in operation,convenient in installation and maintenance.
