PE250×400颚式破碎机的设计研讨.doc

摘要 洛阳理工学院毕业设计（论文） PAGE IV  PAGE 1 PE250×400颚式破碎机的设计 摘 要 目前国内使用的破碎机类型很多，主要有鄂式破碎机、锤式破碎机、圆锥破碎机、反击式破碎机和辊式破碎机。复摆式颚式破碎机与简摆式相比较，其优点是：质量较轻，构件较少，结构更紧凑，破碎腔内充满程度较好，所装物料块受到均匀破碎，加以动颚下端强制性推出成品卸料，故生产率较高，比同规格的简摆颚式破碎机的生产率高出20-30%； 本设计需求参数为进料口尺寸：250×400mm；最大进料粒度：210mm；处理能力：3-13m/h；偏心轴转速：300r/min；排料口调整范围：20-60mm；电动机功率：11-15KW。设计分析了破碎机的发展现状和研究颚式破碎机的意义及复摆颚式破碎机机构尺寸对破碎性能的影响，计算确定了PE250×400的机构参数，设计内容主要包括复摆颚式破碎机的动颚、偏心轴、皮带??、动颚齿板、定颚齿板、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的作用作了介绍。 关键词：复摆颚式破碎机，带传动，飞轮 Design of PE250×400 Jaw-fashioned Crusher ABSTRACT Currently ，the type of the crusher is multitudinous in domestic, mainly including jaw crusher, hammer crusher, cone crusher,impact,breaker,and roll,crusher,Compared with fine impact crusher，SBM（swinging jaw break machine）′s advantage is: quality is lighter, less compact structure component, broken filled with degree is good, with materials by uniform broken, to block bottom mandatory move jaw is unloading, launch finished higher, than with specifications productivity of fine impact crusher 20-30% higher than the productivity; This design is done for：the feeding port size is 250×400mm; Maximum feeding granularity is 210mm; Production efficiency is 3-13m3/h; Eccentric shaft speed is 300r/min; Discharging mouth adjustment range 20mm to 60mm; Motor power is 11-15KW. This design analysis of the current development of the crusher,the meanings of researching the crusher,how the dimensions of jaw crusher effect on the performance of the broken, calculate and determine the PE250 x 400 structure parameters, the design content mainly includes swing jaw, eccentric shaft, pulley, seeing jaw gear plate, and settled jaw gear plate and frame and some other important components; In addition, jaw crusher principle and characteristics and main component function is introduced。 KEY WORDS: Jaw crusher,Belt drive,Flywheel 前言 目　录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc452645231 前　言  PAGEREF _Toc452645231 \h 1  HYPERLINK \l _Toc452645232 第1章 绪论  PAGEREF _To
