磁滞联轴器Magnetic-delaycoupling磁滞联轴器主要由***磁钢、感应盘及外壳制成，它们之间产生一个交替多极磁场，当电动机拖动感应盘高速旋转时，通过磁耦合带动磁盘运转。由于负载力矩的变化会在两盘之间出现转数滑差，可以产生一个抗拒滑差的扭转力矩，这就是磁滞联轴器在卷筒上得以广泛应用的原因。其内部结构如图2。Magnetic-delaycouplingismainlyc***istofpermanentmagneticsteel,inductingdiskandshell,andtherewillbeamultipolesmagneticfield,whenthemotordrivestheinductingdiskquicklyrotating,whichalsobringthemagneticdiskrotatingalongwithitthrongcoupling.Duetotherotateslidingdifferencebetweentwodisks,ananti-slidingdifferenceturnmomentwillbecreated,thatisalsothereasonwhythisseriesofmagnetic-delaycouplingiswidelyused.Theinternalstructurepleaseseesketch2.图2磁滞联轴器结构及外形Sketch2:Structuralandoutlinemagnetic-delaycoupling1、输出轴2、挡圈3、轴承62064、轴承套5、轴承60146、机体7、磁外壳8、磁座9、磁体块10、永磁块11、橡胶耐***12、磁极间隙13、感应盘14、调整栓15、轴承620616、螺钉M6×1817、堵盖18、联轴节19、输入轴20、电机21、反向轴承22、联接套output2.snapring3.bearing62064.bearingbushing5.bearing60146.machinebody7.magneticshell8.magneticpedestal9.magneticblock10.permanentmagneticblock11.heatresistantrubbercord12.magneticrolespace13.inductingdisk14.adjustingbolt15.bearing620616.screwM6x1817.blockcover18.coupling19.inputshaft20.Anti-directionbearing21.connectingbushing)
