柔性结构滚筒的特长：自从二十世纪六十年发钢丝胶带之后，胶带输送机迎来大容量、长距离输送的时代，为了满足大输送量的要求，经反复研究试验，***终将滚筒结构从钢性结构转换为柔性结构。柔性结构滚筒从外观看与刚性结构滚筒基本相同，但是其结构上有着本质的区别，柔性结构滚筒允许滚筒在许用应力范围内产生绕曲弯形，用以吸收一部分动能，缓和局部应力集中，进而提高滚筒整体的疲劳强度，延长使用寿命。我公司制造的柔性结构滚筒使用寿命可确保连续运转六年以上。柔性结构滚筒的设计要点：滚筒转动时产生的弯矩和扭矩，特别是交变动载荷作用在滚筒上，致使滚筒受力非常复杂。因此，设计时必须***计算疲劳强度。FeaturesofFlexibleStructurePulleysSincethedevelopmentofsteelwirebeltinthe60softhe20thcentury,beltconveyorhascomeintotheageoflargecapacityandlongdistancecarrying.Inordertomeettheneedsoflargecapacitycarrying,passthroughresearchandtesttimeaftertime,wechangethepulleyfromrigidstructuretoflexiblestructure.Theappearanceofrigidstructurepulleysandflexiblestructurepulleysarebasicallysimilar.buttheirinnerstructureareabsolutelydifferent.Forflexiblestructurepulleys,flexibilitydistortionisallowedinthefieldofallowablestresstoabsorbpartialkineticenergy,relaxlocalstressconcentration,andaccordinglyenhancethewholefatigueintensityofpulleysandextendlife-span.Itcanensureofmorethansixyearsofcontinuousoperation.DesignEssentialsotFlexibleStructurePulleysOnaccountofbendingmomentandtorqueproducedfromtherunningofpulleys,especiallythealternantfluctuantloadsactingonpulleys.thecompositionofforceputonpulleysisverycomplicated.Therefore,thefatigueintensitymustbeaccuratelycalculatedduringtheprocessofdesign.)
