摘 要
選煤廠的篩分機(jī)數(shù)量很多,所以對(duì)篩分機(jī)的要求也越來越高。不但要求它具有較高的生產(chǎn)率、較好的篩分效率或脫水效果、較低的動(dòng)力消耗;而且還要具備結(jié)構(gòu)簡(jiǎn)單、制造容易、安裝維修方便等機(jī)械性能。由于滾軸篩、圓筒篩上述性能較差,在使用上受到了限制,逐漸被工藝效果好、構(gòu)造簡(jiǎn)單、維修方便的振動(dòng)篩所代替。
自同步振動(dòng)篩是一種廣泛用于散體物料分級(jí)的設(shè)備。在選煤等工業(yè)領(lǐng)域,用于分級(jí)、脫水、脫泥和脫介。其篩分性能尤其重要。
本文系統(tǒng)地闡述了雙電機(jī)自同步振動(dòng)篩的應(yīng)用現(xiàn)狀和發(fā)展趨勢(shì),論述了設(shè)計(jì)高效雙電機(jī)自同步振動(dòng)篩的必要性;同時(shí)對(duì)雙電機(jī)自同步振動(dòng)篩的原理進(jìn)行了分析,計(jì)算了振動(dòng)篩的動(dòng)力學(xué)參數(shù)、運(yùn)動(dòng)學(xué)參數(shù),設(shè)計(jì)計(jì)算了激振器的軸、偏振塊的參數(shù)和結(jié)構(gòu),減震裝置,篩框的設(shè)計(jì),并進(jìn)行聯(lián)軸器的選型等。

Abstract
The number of Washery screening machine is very large . So the demands on the screening machine also getting higher and higher. It is not only demand its higher productivity, better screening efficiency or effectiveness dehydration and low power consumption, but also with mechanical properties of simple structure, easy to manufacture, convenient to installation and maintenance and so on .As such properties of the roller sieve and sieve cylinder is very poor, it has became the restrictions of the fields of use. And it has been gradually replaced by the shaker because of its good process effect, simple structure and easy to maintenance .
Synchronization shaker is a widely used equipment in the classification of bulk materials. In the fileds of industrial such as coal chosen ,it has been used for grading, dewatering, desliming and sculping. Its properties of screening is particularly important.
In this paper, systematically expounded the application status and the trends of the design of the the two-synchronous motor,discussing the necessity of the two-synchronous motor. While analysising the principles of the two-synchronous motor, Calculating the kinetic parameters of the shaker,the parameters of kinematics, designing and calculating the structure and parameters of the shaft and the polarization block of the exciter, finishing the design of shock absorber and screen frame and also finishing selection of the coupling .
Key words:double motor;self-synchronous motor;shaker vibrator
