复摆鄂式破碎机 姓 名： 指导老师： [摘要]国内使用的颚式破碎机类型很多,但常见的还是传统的复摆颚式破碎机。复摆颚式破碎机的出现已有140多年的历史,经过人们长期的实践和不断完善与改进,其结构型式和机构参数日臻合理, 结构简单、制造容易、工作可靠、维修方便，故在冶金、矿山、建材、化工、煤炭等行业使用非常广泛。随着现代化的发展，各工业部门对破碎石的需求进一步增长，研究复摆鄂式破碎机具有很重要的意义。本毕业设计主要是为满足生产需求：进料口尺寸：；出料口尺寸：；进料块最大尺寸：；产量：。而研究的。主要研究复摆颚式破碎机的运动分析、V带的选择，鄂板、齿板磨损的分析，各种工作参数的选择，工作机构的优化。重点研究传动的设计和系统的优化。 [关键词] 复摆鄂式破碎机 传动 磨损 Jaw-fashioned Crushe [ABSTRACT] The domestic use jaw type breaker type are very many,But common traditional duplicate pendulum Jaw-fashioned Crushe. The duplicate pendulum jaw type breaker appearance had more than 140 years history,And consummates and the improvement unceasingly after the people long-term practice,Its structure pattern and the organization parameter are day by day reasonable, The structure simple, the manufacture is easy, the work reliably, the service convenient, therefore in profession use and so on the metallurgy, mine, building materials, chemical industry, coal is extremely widespread. Along with the modernized development, various industry sector further grows to the broken crushed stone demand, studies the duplicate pendulum Jaw-fashioned Crushe to have the very vital significance. This graduation project mainly is for meets the production need:Feed head size: ; Discharge hole size: ; Feeding block greatest size: ; Output: .Mainly studies the duplicate pendulum Jaw-fashioned Crushe the movement analysis, V belt choice, the analysis which the Jaw-fashioned Crushe, the toothed rack wears, each kind of operational parameter choice, operating mechanism optimization. Key research transmission design and system optimization.

Blake发明的。自第破碎机的生产效率鄂式破碎机结构简单、制造容易、工作可靠、使用维修方便等优点，所有在冶金、矿山、建材、化工、煤炭等行业使用非常广泛。80年代以来，我
