摘要 破碎机自发明以来，至今已有一百多年，在这一个多世纪里，发展出各式各类破碎机。在这种类繁多的破碎机中，当属复摆颚式破碎机最受人们的青睐。复摆鄂式破碎机之所以受到人们的青睐是因为它具有很多优点，由于其结构并不复杂，因此操作人员很容易上手，而且这种破碎机的价格还不高，因此许多企业都争相购买。因此该类型破碎机现在基本上成为大中型矿山的作业必备设备。 上述破碎机有机架、偏心轴、动颚板、定颚板、推力板五个主要机构。除此之外，固定齿板、衬板、挡罩、垫片、滑块、推力板、止动螺钉、锁紧装置等也属于破碎机不可缺少的一部分。 本次设计可以分为以下四个步骤，第一：对复摆颚式破碎机现状进行文献搜索，对其工作原理进行探究，结合本次设计要求，通过对破碎机的整体结构进行分析，得到所需的主要参数；第二：对破碎机再次进行更为细致的分析，进而确定全部参数；第三：对上述破碎机设备中所需计算部分进行设计计算；四：利用工程软件对破碎机的二维图纸进行绘制，利用三维建模软件建模。 关键词：复摆；颚式破碎机；偏心轴；动颚 Abstract Si

n this variety of crushers, the compou
nd pe
ndulum jaw crusher is the most popular. The reaso
n why compou

ndulum jaw crusher is favored by people is that it has ma
ny adva
ntages. Because its structure is
not complex, it is easy for operators to start. Moreover, the price of this crusher is
not high, so ma
