| 摘要:本设计为PFK-1212可逆反击式破碎机的设计，主要研究内容：转子的机 构设计；板锤的设计；反击板的设计。 本设计由转子型号入手，参考PFK-1212反击式破碎机的相关参数，初步根据已知的转子的转速，从而确定线速度、板锤大小、数量等相关数据。在保证生产率和破碎粒度的前提下完成总体结构的设计，然后根据总体结构，从而确定本设计的破碎机各个主要零部件的设计。5031 本文在传统破碎机的基础上研制了一种新型的可逆反击式破碎机，重点介绍了可逆反击式破碎机的工作原理，并通过对关键零部件的强度校核计算优化了破碎机的整体结构，同时还分析了它的优缺点以及应用范围，然后对整个破碎机的结构进行了设计，其主要是对机架的设计、反击板的设计以及对转子的设计及锤头材料的选择提供了合理的参数，从而可缩短整个产品的开发周期，提高产品的可靠性，最后对整个机器的操作、安装、文护进行了详细的说明，可为选煤企业破碎机的选择和使用提供参考。 关键词：反击式破碎机；研究内容；结构；计算；毕业论文 Reversible Crusher Design Abstract：The specification of the design is theReversiblecrusher design, And it mainly contents: the institutional design of the rotor; plate hammerstructural design; plate counterattack design. The design starts from the specifications of the rotor, and it references the relevant parameters of PFK-1212 crusher. Initially it sets the rotor speed, so that I can design the board hammer size, number and other relevant data with the rotor speed. Productivity and size of the crushed materials should be ensured before the overall structure of the design finished, according to the whole structure, I could determine the design of all the major components of the design. The design in the article introduced a new Reversible crusher beyond the traditional one, It highlighted the working principle of Reversible crusher, and through the main parts of the strength calculation which optimized the overall structure of the Reversible crusher, moreover, analyzed its advantages and disadvantages and application, and then Reversible crusher of the whole structure was improved design, which is mainly improved rotor design and material selection of nutation reasonable parameters, also can shorten the product development cycle and improve product reliability. Finally, described the operation installation maintenance of the entire machine minutely. Maybe can provide a reference of the use and preparation for coal enterprise.
