自定中心振動篩設計 學生姓名：劉城建 班級：0781052 指導老師：吳暉 摘要：目前我國各種選煤廠使用的設備中,振動篩是問題較多、維修量較大的設備之一。這些問題突出表現(xiàn)在篩箱斷梁、裂幫,稀油潤滑的箱式振動器漏油、齒輪打齒、軸承溫升過高、噪聲大等問題,同時伴有傳動帶跳帶斷帶等故障。這類問題直接影響了振動篩的使用壽命,嚴重影響了生產(chǎn)。自定中心振動篩可以很好的解決此類問題，因此本次設計的振動篩為自定中心振動篩，該系列振動篩主要用于煤炭行業(yè)中物料分級、脫水、脫泥、脫介等作業(yè)。其工作可靠，篩分效率高，但設備自身較重。設計分析論述了設計方案，包括振動篩的分類與特點和設計方案的確定；對物料的運動分析，對振動篩的動力學分析及動力學參數(shù)的計算，合理設計振動篩的結構尺寸；進行了激振器的偏心塊等設計與計算，包括原始的設計參數(shù)，電動機的設計與校核；進行了主要零部件的設計與計算，皮帶的設計計算與校核，彈簧的設計計算，軸的強度計算，軸承的選擇與計算，然后進行了設備維修、安裝、潤滑及密封的設計，最后進行了振動篩的環(huán)保以及經(jīng)濟分析。 關鍵詞：振動篩；激振器；自定中心 指導老師簽名： Custom Design Center Shaker Student name: Liu Chengjian Class:0781052 Supervisor: Wu Hui Abstract: At present, China's coal preparation plant all the equipment used in the shaker is more problems, maintenance of one of the larger equipment. These issues in sieve outstanding performance me off beam, crack help, lubrication oil dilute the box-type vibrator oil spills, fighting tooth gear, bearing temperature rise too high, major issues such as noise, accompanied by dancing with broken belts, such as fault zone. Such issues directly affecting the life of the shaker, which has seriously affected the production. 2YAH1548-round good shaker can solve such problems, so this shaker designed for round 2 YAH1548-shaker, the series of major shaker in the materials used in the coal industry classification, dehydration, desliming, such as referrals from Operations. Its reliable, efficient screening, but their heavy equipment. Design analysis on the design options, including the classification and shaker features and design programmes to be confirmed; materials on the movement of the shaker and the dynamics of the parameters, to design the structure of vibrating screen size; conduct The eccentric block of the exciter, such as design and calculation, including the original design parameters, motor design and verification; were the main components of the design and calculation, belts and check the design and calculation, the design of spring, the axis of Strength, the choice of bearings and calculation and then proceed to the maintenance of equipment, installation, lubrication and seal the design, a shaker final environmental and economic analysis.
