LK联轴器

联轴器系列形式以及特点LK（标准型）适用于联接两同轴线大中功率、振动冲击较大的轴系传动。结构合理，在更换弹性件（易损件）时主机半联轴器不用作轴线移动（对于重型机械设备此特点尤为重要），能有效地阻尼和减少运动过程中所产生的振动和冲击。两个轴套的爪形齿在圆周方向相互错开半个齿距，在其间隙装入一个扇形弹性元件隔开。当轴在安装时出现偏差，弹性元件的齿形避免了应力集中。LK（标准型）能有效纠正轴向、经向和角向的安装偏差。一般弹性联轴器中间的弹性元件承受弯曲力和压力，易磨损，而LK（标准型）的弹性元件仅受压力，因而能承受更大的负荷。是完全由弹性元件受压来传递力矩的。LK（标准型）在预应力作用下保证了无齿隙的传动，极大地改善了传动系统的动态特性。LK（标准型）既能补偿轴安装偏差，又能吸收振动和冲击载荷。LK（标准型）免维护，可使用在各种通用设备。传递转矩大，除了标准型号，也有法兰结构和加长中间体等很多特殊型号。LK（标准型）有多种变型设计来满足各种应用的需要，因为它有多种模块可供组合。可用已有的模块进行组装，以满足不同的轴间距。LK（标准型）联轴器基本参数和主要尺寸表1LK型弹性块联轴器基本参数和主要尺寸mm型号公称转矩许用轴孔直径轴孔长度DBB1AS质量转动惯性TnN.m转速nr/mind1(H7)d2(H7)Y型J1型m≈kgI≈kg.mLL1LK11000001185190-220352282400286140180650022240-260410330LK21250001120220352282450290145190660030240-260410330280470380LK31600001060240-260410330500316155200673040280-320470380LK42000001000260410330550336165210685054280-320470380340550450LK5250000950280-3204703806003671802207100070340-360550450LK6315000900300-3204703806504072002307123598340-380550450LK740000085032047038070043721524071450125370-380550450400650540LK8500000800360-38055045075045822525081900170400-440650540LK956000075538055045080047023526082135200400-460650540LK10630000710400-48065054085049824527082400290LK11710000670420-50065054090051825528082700353LK12800000630440-500650540950540265295103100455530800680LK13900000605450-5006505401000550270310103430535530800680LK141000000580460-5006505401050570280325103795635530-560800680LK151120000560480-5006505401100600295340104200748530-580800680LK161250000545480-5006505401150620305355104490850500-580800680LK1714000005305006505401200650320370104800968530-600800680LK181600000515530-63080068012506803353851053201155LK191800000500560-63080068013007203554051059001358LK202000000480580-630800680135074036542510674017006701000880LK212240000465600-63080068014007703804451077002090670-7101000880LK22250000045063080068014507923904651288002575670-7501000880LK232800000400670-750100088015008124004901511000424780012501120LK243150000385710-7501000880160083641251515120604985800-85012501120LK2535500003707501000880170086512554020132205850800-90012501120LK264000000360800-9001250112018008954405652014500687095015001320LK274500000340850-100012501320190091545059525170009390LK285000000325900-1060125013202000945465625251900011050LK295600000315950-1120150016002100975480655302100013000LK3063000003001000-11801500160022001005495690302300015300LK3180000002801060-12501500160023001200550750402500019000LK32100000002501060-12501500160024001300600800402800021300注：1、瞬时最大扭矩Tmax不得超过公称转矩Tn值的1.5倍，即Tmax≤1.5Tn；2、轴孔和键槽型式尺寸补符合GB3852的规定，轴孔型式及长度L、L1可根据需要选取；3、各规格的轮毂直径应大于或等于1.6dmax（规格中最大轴孔直径）。LK联轴器基本参数许用补偿量表3、LK型型号许用补偿量LK1-LK8LK9-LK13LK14-LK122LK23-LK30径向△Y2.558轴向△X±3±5±7角向α1°00′1°00′表4、LKA型型号许用补偿量LKA1-LKA6LKA7-LKA10LKA11-LKA18LKA19-LKA27LKA28-LKA30径向△Y25710轴向△X±3±5±7±8角向α1°30′1°40′2°00′注：1、表3、表4、表5所列补偿量是指由于制造误差，安装误差，工作载荷变化所引起的冲击振动，机座变型和温度变化等综合因素所形成的两轴线相对偏移量的补偿能力。2、径向偏移量测量的部位，在半联轴器最大外圆宽度处。龙翔联轴器科技技术公司
