锤式破碎机的设计 摘要 锤式破碎机大量应用于水泥厂、电厂等各个部门，所以，它的设计有着广泛的前景和丰富的可借鉴的经验。其设计的实质是，在完成总体的设计方案以后，就指各个主要零部件的设计、安装、定位等问题，并对个别零件进行强度校核和试验。并在相关专题中，对锤头的寿命延长进行比较详细的分析。在各个零部件的设计中，要包括材料的选择、尺寸的确定、加工的要求，结构工艺性的满足，以及与其他零件的配合的要求等。在强度的校核是，要运用的相关公式，进行危险部位的分析、查表、作图和计算等。并随后对整体进行安装、工作过程以及工作后的各方面的检查，同时兼顾到维修、保险装置等方面的问题，最后对两个主要工作零件的加工精度、公差选择进行分析，以保证破碎机最终设计的经济性和可靠性。 关键词：锤式破碎机；锤头；强度；公差 Abstract Hammer type breakers are applied to such each department as the cement plant, power plant, etc. in a large amount, so its design has an extensive prospect and experience that can be used for reference. Its design essence is, formerly after total conceptual design, a design which points each main spare part, question of installing and making a reservation etc., and carry on the intensity to check and test to the specific part, and in relevant thematic parts, analysis of comparing question that the life-span of very beginning of the hammer lengthens in detail. In the design of each spare part, should include the choice, sureness, demand processed, structure craft satisfication of the size of the material, and the demand for cooperating with other parts, etc.. When the intensity is checked, should use relevant formulae, carry on the analysis of the dangerous position, need to check form, mapping, calculation, etc.. Then to install , work course , work situation after predict that carries on more overall inspection whole, give consideration to the question in such respects as maintaining and safety ,etc. at the same time. Finally, choose to analyse in machining accuracy, public errand to two groundwork parts, economy and dependability that the breaker soed as to ensure is designed finally. Keywords: Hammer type breakers, hammer, intensity, tolerance 不要删除行尾的分节符，此行不会被打印目录 摘要 I Abstract II 第1章 绪论 1 1.1 课题背景 1 1.2 选题分析 1 1.3 国内外现状 1 1.3.1 国内发展情况 1 1.3.2 国外发展情况 2 第2章 原理及其设计方案的确定 3 2.1 破碎机的结构及原理 3 2.1.1 破碎原理 3 2.1.2 破碎机的主要结构 3 2.2 设计方案 4 2.3 本章小结 4 第3章 锤式破碎机的电动机功率的计算和选择 5 3.1破碎机电动机功率的计算 5 3.1.1 综合各种因素计算功率 5 3.1.2 根据生产实践以及引用
