摘要

錘式破碎機(jī)大量應(yīng)用于水泥廠、電廠等各個(gè)部門(mén)，所以，它的設(shè)計(jì)有著廣泛的前景和豐富的可借鑒的經(jīng)驗(yàn)。其設(shè)計(jì)的實(shí)質(zhì)是，在完成總體的設(shè)計(jì)方案以后，就指各個(gè)主要零部件的設(shè)計(jì)、安裝、定位等問(wèn)題，并對(duì)個(gè)別零件進(jìn)行強(qiáng)度校核和試驗(yàn)。并在相關(guān)專(zhuān)題中，對(duì)錘頭的壽命延長(zhǎng)進(jìn)行比較詳細(xì)的分析。在各個(gè)零部件的設(shè)計(jì)中，要包括材料的選擇、尺寸的確定、加工的要求，結(jié)構(gòu)工藝性的滿足，以及與其他零件的配合的要求等。在強(qiáng)度的校核是，要運(yùn)用的相關(guān)公式，進(jìn)行危險(xiǎn)部位的分析、查表、作圖和計(jì)算等。并隨后對(duì)整體進(jìn)行安裝、工作過(guò)程以及工作后的各方面的檢查，同時(shí)兼顧到維修、保險(xiǎn)裝置等方面的問(wèn)題，最后對(duì)兩個(gè)主要工作零件的加工精度、公差選擇進(jìn)行分析，以保證破碎機(jī)最終設(shè)計(jì)的經(jīng)濟(jì)性和可靠性。

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.
