摘要本课题研究的卧式钢筋切断机的工作原理是：发动机由一级和二级三角齿轮制动带动曲轴转动后，推动连杆，移动支架上的刀片，使其恢复直线运动，动叶片和定叶片错相切断钢筋，卧式安装，电机保护，三相短路异步电机。先选择三级减速器，再选择一级减速器。每一级的减速器都有他们独特的功能，第一节的减速器的功能之中优点都比较的多有噪音低等优点，二级减速器的功能也是非常的多，并且它有着不能被代替的作用，因为它的齿轮在运转的时候，主要是靠的是动力，所以它的特点也是非常的特别的，而且它的优点也是不可替代的，它主要的优点有：工作效率大，精度高，而且它的工作的时间也是比较的长。通过制动系统的传动，能量被引入在系统之中，因为我们采用的是曲柄滑块的机构，来进行一个直线型的往返运动，这样可以驱动它进行运动。关键词切断；钢筋；齿轮；曲柄滑块ABSTRACTTheworkingprincipleofthehorizontalsteelbarcuttingmachinestudiedinthispaperis:aftertheengineisdrivenbythefirstandsecondtriangulargearbrake,thecrankshaftrotates,theconnectingrodispushed,thebladeonthebracketismovedtomakeitreturntolinearmotion,themovingbladeandthefixedbladearestaggeredtocutthesteelbar,thehorizontalinstallation,themotorprotection,andthethree-phaseshort-circuitasynchronousmotor.Firstselectthethree-stagereducer,andthenselectthefirststagereducer.Theprimarytransmissionhastheadvantagesofbufferzone,vibrationreduction,stableoperation,lownoise,anticommonoverloadandsoon.Thesecondaryreducerandgeartransmissioncanbeusedforspacemovementandpowertransmissionbetweentwoshafts.Atthesametime,ithasthecharacteristicsoflargepowerrange,hightransmissionefficiency,highprecision,longservicelifeandsafework.Throughthetransmissionofthebrakingsystem,energyisintroducedintotheactuator.Theoperatingmechanismofthesteelbarswitchneedslinearreciprocatingmotion,sothecrankslidermechanismcanbeusedtodrivethecampulleydrivemechanismKeywordscuttingarchitecturalgearslider-crank目录摘要.................................................................................................................................................................1ABSTRACT...................................................................................................................................................21引言...........................................................................................................................................................31．1概述.............................................................................................................................................31．2我国的发展现状和原因.............................................................................................................51．3国内外对比51．4题目的选取.................................................................................................................................51．5钢筋切断机的工作原理.............................................................................................................52电机选择.....................................................................................................................................................52.1切断钢筋需用力计算......................................................................................................................62.2功率计算.........................................................................................................................................63.传动结构设计...........................
