华东理工大学学士学位论文颚式破碎机的研究.doc

摘要 颚式破碎机俗称颚破，由动颚和静颚两块颚板组成破碎腔，模拟动物的两颚运动而完成物料破碎作业的破碎机。广泛运用于矿山冶炼、建材、公路、铁路、水利和化工等行业中各种矿石与大块物料的破碎。被破碎物料的最高抗压强度为320MPa，颚式破碎机的动颚直接悬挂在偏心轴上。由于动颚是偏心直接带动的，所以活动颚板可以同时做垂直和水平的复杂摆动，颚式破碎机对石块不但能起到压碎和劈碎的作用，还能起到碾碎的作用。随着科技的发展，矿石业的需求也大大增加，各种不同型号的颚式破碎机的设计显得尤为重要。 本毕业设计主要是对9501250（进料口尺寸（宽×长）Abstract Jaw crusher is commonly known as the broken jaw, by moving jaw and quiet jaw two jaw plate component crushing cavity, Simulate the movement of animals to complete two jaw crusher material crushing operation, Widely used in mining, building materials, smelting broken highway, railway, water conservancy and chemical industry, all kinds of ores and bulk materials. The highest compressive strength of broken material is 320MPa, jaw crusher’s jaw hang directly on the eccentric shaft. The movable jaw is eccentric driven directly, so the movable jaw plate can do complex swing vertically and horizontally at the same time, jaw crusher of the stone can not only play the role of crushing and breaking, but also play the role of ground. With the development of science and technology, ore industry demand also increases greatly, various types of jaw crusher design is particularly important. This graduation design is mainly to the 950x1250 (inlet size (width * length)) jaw crusher’s design,Split parts of the crusher above, draw all parts drawings, then draw the assembly drawing. Calculation the design of main parameters of jaw crusher and its main structure, the design content mainly includes jaw crusher jaw, eccentric shaft, a belt pulley, a front wall, a side wall, flange, end cover, and other important components, In addition,main parts ‘s working principle and characteristics of jaw crusher is introduced, At the same time on the machine parameters (spindle speed, production capacity, crushing force and power) were calculated and the eccentric shaft made the design. In addition, also introduce the significance and crushing process of crusher, jaw crusher operation and maintenance etc...
