【正文】 劈裂和彎曲作用而破碎。 80 年代以來，我 國 對復(fù)擺鄂式 破碎機(jī) 的研究和產(chǎn)品開發(fā)取得了較大的發(fā)展。 破碎機(jī)是將開采所得的 天然的石料按一定尺寸進(jìn)行破碎加工的機(jī)械。在此過程中，其結(jié)構(gòu)得到不斷的完善 ， 而鄂式 破碎機(jī)的 結(jié)構(gòu)簡單 ，安全 可靠， 石 料可供破碎機(jī)械來進(jìn)在基本建設(shè)工程中 ， 需要大量的，各種不同粒徑的砂、石作為生產(chǎn)之用。 關(guān)鍵詞 : 復(fù)擺鄂式破碎機(jī) 傳動 磨損 Abstract IV Abstract The domestic use jaw type breaker type are very many, But mon traditional duplicate pendulum Jawfashioned Crusher. The duplicate pendulum jaw type breaker appearance had more than 140 years history, And consummates and the improvement unceasingly after the people longterm practice, Its structure pattern and the anization parameter are day by day reasonable, The structure simple, the manufacture is easy, the work reliably, the service convenient, therefore in profession use and so on the metallurgy, mine, building materials, chemical industry, coal is extremely widespread. Along with the modernized development, various industry sector further grows to the broken crushed stone demand, studies the duplicate pendulum Jawfashioned Crusher to have the very vital significance. This graduation project mainly is for meets the production need: Feed head size: ? ?mm1202000 ? 。從動顎豎 直位移仿真結(jié)果中也可以看出垂直的行程較大，從而導(dǎo)致襯板磨損較快，降低襯板的使用壽命，故復(fù)擺顎式破碎機(jī)一般用于中小型機(jī)型。 I 復(fù)擺鄂式破碎機(jī)的設(shè)計(jì) 目 錄 摘 要 ........................................................................................................................
