锤式破碎机机械结构设计
MECHANICAL STRUCTURE DESIGN OF HAMMER CRUSHER
摘要
在各类基础建设中会用到大量的石块、沙粒，第一代的破碎机是在各种动力机械技术较为成熟后逐渐制造出来的，比如：蒸汽机技术、电动机技术。
破碎机的作用是对破碎料进行破碎使其变成一定尺寸的机器，破碎机的研发，生产效率有了相当大的提高，生产效率提高且安全性能也提高了。锤式破碎机一般会根据有多少个转子分为拥有一个转子的锤式破碎机与拥有两个转子的锤式破碎机，根据转盘上锤头的排数可以分为一排锤头的锤式破碎机和多排锤头的锤式破碎机，根据转子拥有的转向个数分为单转向不可逆式锤式破碎机和双转向可逆式锤式破碎机。还有结构较为简单的锤式破碎机，例如：十字粉碎机，链环式碎煤机等。
本设计的内容主要是，在对机器整体设计初步完成之后，对机器中较为重要的零部件的创新、位置确定、装卸等问题与对机器中一些零部件强度校核与试验的研究。其中单附章节，对锤头寿命延长进行细致的分析。每个个零部件的研发设计，都会包括选择材料、确定尺寸、确定加工方案，满足结构工艺性，及与其他部件之间的配合问题等。校核强度是使用相关公式，对主要部分进行解析、查表、查表、作图等。在整体的安装与工作开始到工作结束过程中进行检查，并同时对维修与保险装置进行检查，本设计的后半部分主要是对机器中主要零件加工时的精度与所使用公差类型、数值的选择的分析，保证最后设计出的破碎机具有可靠性与经济性的双重优势。

Abstract
A large number of stones and sand grains will be used in all kinds of infrastructure construction. The first generation of crusher is made gradually after the maturing of various power and machinery technology, such as steam engine and motor technology.
The function of the crusher is to break the crushing material into a certain size machine. The crusher's R & D, the production efficiency has been greatly improved, the production efficiency is improved and the safety performance is also improved. A hammer crusher is usually divided into a hammer crusher with a rotor and a hammer crusher with two rotors on the basis of the number of rotors. According to the number of hammer heads on the turntable, a hammer crusher and a hammer crusher with multiple rows of hammers can be divided into a single steering irreversible number according to the steering number of the rotors. Hammer crusher and double steering reversible hammer crusher. There are also simple Hammer Crushers, such as cross grinder, chain type coal crusher, etc.
The main content of this design is to study the innovation, position determination, loading and unloading of the more important parts in the machine and the strength checking and test of some parts in the machine after the overall design of the machine is completed. Among them, the single attached chapter is a detailed analysis of the prolongation of the life of the hammer. The research and design of each component will include the selection of material, the determination of the size, the determination of the processing scheme, the technical nature of the structure, and the coordination with other components. Checking strength is to use relevant formulas to parse, look up, look up and map out the main parts. The final part of this design is mainly the analysis of the precision of the main parts in the machine and the selection of the type of tolerance and the value of the tolerances used in the machine, which ensures the reliability of the final crusher. The dual advantages of the economy.
