PEF800×1000复摆颚式破碎机最后版.docx

PEF800×1000复摆颚式破碎机整体结构和动鄂部设计摘要目前，国内外使用的颚式破碎机种类很多, 复摆颚式破碎机结构简单，质量较轻，构件较少，结构更紧凑，生产率高，操作和维修方便等优点，所以在物料破碎作业中运用最广泛的仍然是复摆颚式破碎机。我设计了复摆颚式破碎机PEF800×1000（E：颚；P：破；F:复；800×1000：进料口宽度×长度），其工作原理是：电机驱动皮带，通过皮带轮带动偏心轴旋转。动颚与偏心轴相连，当偏心轴旋转时，动颚随之上下往复运动。当动颚向上运动时，肘板与动颚夹角变大，肘板推使动颚向前运动而靠近定颚，致使物料被挤压碾碎。当动颚向下运动时，肘板与动颚夹角变小，通过拉杆与弹簧装置，动颚离开定颚，物料被排排卸出去，从而达到连续生产的目的。设计内容主要包括了复摆颚式破碎机的动颚、偏心轴、皮带轮、动颚齿板、机架等一些重要部件；另外对颚式破碎机的工作原理及特点和主要部件作了介绍，包括保险装置、调整装置、机架结构、润滑装置等；同时对机器参数（主轴转速、生产能力、破碎力、功率等）作了计算，保证了安全的要求。关键词：颚式破碎机，工作原理，动颚。The design ofPEF800X1000 compound pendulum jaw crusher ’soverall structure and movable jaw ABSTRACTAt present, domestic and international use of many different types of jaw crusher,Jaw Crusher simple structure, the quality of light, fewer components, more compact structure, high productivity, easy operation and maintenance, etc., so the material crushing operation is the most widely used Jaw Crusher.I design a Jaw Crusher PEF800x1000（F stands forcompound;E stands for Jaw;P stands for Crusher; 800x1000 stands for the discharge port’s width and length）, its working principle is: the motor drive belt, pulley driven by the eccentric axis. Moving jaw and the eccentric shaft, when the eccentric shaft rotates, moving up and down reciprocating motion along the jaw. When the moving jaw moves upward, the angle between toggle plate and moving jaw becomes larger, fixed jaw bracket bringing forward movement close to the scale, causing the material to be extruded crushed. When the moving jaw moves down, the angle between toggle plate and moving jaw decreases, through the rod and spring mechanism, moving the fixed jaw to leave, the material is ranked discharge out. With the constant rotation of eccentric shaft, moving the jaw back and forth cycle of movement, constantly being broken disposing of the material, to achieve the purpose of continuous production. The content of this design totally include jaw crusher’s move jaw, eccentric shaft, belt pulley, toothed rack of move jaw, rack and some important compon
