摘要:反击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,同时兼顾到文修、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。8007 关键词 破碎机 锤头 强度 公差 The design of PFK1012 - reversible counter-attack crusher rotor 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 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.
