圓形振動篩的設計,圓形振動篩的設計,圓形,振動篩,設計 圓形振動篩的設計 摘要： 本設計主要介紹了圓振動篩的國內(nèi)外現(xiàn)狀及其分類和特點，通過對振動篩工作原理的分析及工藝參數(shù)的選擇與確定完成圓振動篩的總體設計。并在確定了設計方案的基礎上對電動機的選擇、主要零部件的結(jié)構設計等做了進一步的研究。 振動篩分機械是近20年來得到迅速發(fā)展的一種新型機器，目前已廣泛應用于采礦、冶金、水利電力、石油化工、煤炭、交通運輸、建筑和鐵道等工業(yè)部門中，用于完成各種不同的工藝過程。最近幾年，各國對振動篩分技術的研究很重視，如強化振動參數(shù)，設備大型化，篩機零部件的三化，自同部技術的推廣應用，新篩機的出現(xiàn)等都是圍繞著振動篩發(fā)展起來的。 設計首先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；篩面物料的運動理論分析；其次進行了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(jié)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；最后進行了主要零部件的設計與計算，包括軸承的選擇與計算，皮帶的設計計算與校核，軸的強度計算和校核，彈簧的設計計算。 關鍵詞： 振動篩 結(jié)構 篩分機械 激振器 指導老師簽名： Design of circular vibrating screen Abstract: This design is mainly introduced the situation at home and abroad and the circle vibrating screen classification and characteristics, and through the analysis of the operation of vibrating screen and the process parameters of the selection and be sure to complete circle vibrating screen of the overall design. In the design plan and determined on the basis of the choice of motor, main parts of the structure design, further research. Vibration screening machines the past 20 years the rapid development of a new machine, has been widely used in industrial sectors of mining, metallurgy, water conservancy, electric power, petrochemical, coal, transport, construction and railway used to complete a variety of different process. In recent years, countries right vibration screening technology very seriously, such as the strengthening of vibration parameters, equipment, sieve machine parts, to promote the use of the same technology, the new screen, and so on are around the shaker development. At the first ,the design analysis expositions design program , including vibrating screen of classification and features and determine of design program; the movement theory analysis of sieve surface material ;at the second, the design analysis dynamics of vibrating screen and the calculation of dynamics parameter; reasonable design vibrating screen of structure size; conduct the design and calculation of stress vibration device of eccentric block, , including original design parameter, motor design; at last, conduct main parts design and calculation, including select and calculation of bearing , design calculation and check of belt , strength calculation and check of axis , design calculation of mechanical spring .
