煤泥破碎机总体设计毕业设计说明书.doc

摘要 煤泥是由细微粒煤，粉化骨石和水组成的粘稠物，具有粒度细，微粒含量多，水分和灰分含量大，热量低，粘结性较强，内聚力大的特点。 本文主要是根据煤泥破碎时出现的粘性大，容易造成机器堵塞等问题设计一台煤泥破碎机。在文中详细讲解了一下破碎煤泥存在的问题，分析每一种破碎机构破碎煤泥会出现的问题，经过分析选择辊式破碎机构。结合设计参数，破碎机效率：50t/h，每天工作8小时，一年工作300天，设计一台齿辊破碎机。本文对工作参数进行了确定，然后进行了带传动，减速器齿轮，传动齿轮和齿辊轴的设计与校核，设计过程中验算了设计的参数，均合理。设计的破碎机中由一台电动机带动皮带，经过液力偶合器传递到减速器，减速器带动辊轴的转动来实现煤泥的破碎。由于齿辊轴是主要破碎机构，对其进行了校核。在破碎过程中会产生振动，我们选择了在大带轮和减速器之间加入了液力偶合器。然后对轴承进行了选择和校核。最后确定了减速器箱体的结构和箱体的基本尺寸。 关键词：煤泥 ；齿辊轴；破碎机 Abstract Slime is by fine coal particles, powder bone stone and water viscous material, with fine particle size, particle content, moisture and ash content are low in calories, strong adhesion, cohesion characteristics. The main purpose of this paper is according to viscous slime crushing of large, easily lead to jam the machine design of a coal crusher. In this paper explain in detail the a broken slime existing problems, analysis each kind of crushing mechanism slime crushing, through analysis and selection of roller crusher mechanism. Combined with design parameters, crusher efficiency: 50t/h, 8 hours a day, a year working 300 days, design a tooth roller crusher. The the working parameters were determined. The followed by a belt drive, gear reducer, transmission gear and the gear and shaft design and verification and design in the process of checking the design parameters are reasonable. Design of crusher is composed of a motor drive belt, after hydraulic coupling transfer to reducer, reducer so as to drive the roll axis of rotation to achieve slime crushing. Since the roller shaft is the main crushing mechanism, it is checked.. In the crushing process will produce vibration, we choose the large pulley and reducer between joined hydraulic coupler. Then the bearing is selected and checked.. Finally, the structure of the reducer box and the basic size of the box are determined.
