有的用户在设备运行几个月后驱动电(sh)机的输出轴断?jin)。ؓ(f)什么减速机把驱动电(sh)机的输出轴扭断了(jin)Qؓ(f)此我们查看了(jin)驱动甉|的输?gu)u横断面，发现与减速机输出轴的横断面几乎完全一栗横断面的外圈较明亮Q而越向u?j)处断面颜色暗Q最后到轴心(j)处是折断的！?是横断面的照片。这充分地说明?jin)造成驱动甉|输出轴断轴的主要原因是甉|和减速机装配时不同心(j)Q?/p>

当电(sh)机和减速机间装配时同心(j)度保证的非常好时Q电(sh)?gu)u承受的仅仅是转动力，q{时也?x)很qx。然而不同心(j)Ӟ输出轴要承受来自于减速机输入端的径向力，q个径向力长期作用将?x)甉|输出轴被q弯Ԍ而且弯曲的方向随着输出轴{动不断变化。输?gu)u每{动一周，横向力的方向变化360度。如果同?j)度的误差较大时Q该径向力甉|输出轴温度升高，光属结构不断被破坏Q最后该径向力将?x)超出?sh)?gu)u所能承受的径向力，最后导致驱动电(sh)?gu)u折断。当同心(j)度的误差大Ӟ驱动甉|输出轴折断的旉短。在驱动甉|输出轴折断的同时Q减速机输入端同样也?x)承受来自于甉|斚w的径向力Q如果这个径向力同时出?jin)二者所能承受的最大径向负L(fng)话，其结果也?x)导致减速机输入端生变形甚x裂。因此，在装配时保证同心(j)度至关重要！

直观上讲Q如果电(sh)u和减速机输入端同?j)，那么甉|和减速机间的配合׃(x)很紧密，它们之间的接触面紧紧相连Q而装配时如果不同?j)，那么它们间的接触面之间就会(x)有间隙。图3中左面的图表C电(sh)机和减速机间的装配很好Q而右图表C配不好，甉|轴和减速机输入端不同心(j)?/p>

同样Q减速机的输?gu)u也有折断或弯曲现象发生，其原因与驱动甉|的断轴原因相同。但减速机的出力是驱动甉|出力和减速比之积Q相对于甉|来讲出力更大Q故减速机输出轴更易被折断。因此，用户在用减速机Ӟ对其输出端装配同?j)度的保证也应十分注意?/p>


?减速机出力太小出现的断轴问?/p>

除了(jin)׃减速机输出端装配同?j)度不好Q而造成的减速机断u以外Q减速机的输?gu)u如果折断Q不外乎以下几点原因?/p>

首先Q错误的选型致所配减速机出力不够。有些用户在选型Ӟ误认为只要所选减速机的额定输出扭矩满_作要求就可以?jin)，其实不然Q一是所配电(sh)机额定输出扭矩乘上减速比Q得到的数值原则上要小于品样本提供的相近减速机的额定输出扭矩，二是同时q要考虑光动电(sh)机的q蝲能力?qing)实际中所需最大工作扭矩。理ZQ用h需最大工作扭矩一定要于减速机额定输出扭矩?倍。尤其是有些应用场合必须严格遵守q一准则Q这不仅是对减速机里面齿轮的保护，更主要的是避免减速机的输?gu)up扭断。这主要是因为，如果讑֤安装有问题，减速机的输?gu)u?qing)其负蝲被卡住?jin)Q这旉动电(sh)机的q蝲能力依然?x)其不断加大出力，q而，可能使减速机的输?gu)u承受的力过光定输出扭矩的2倍而扭断减速机的输?gu)u?/p>

其次Q在加速和减速的q程中，减速机输出轴所乘受瞬间的扭矩如果超q了(jin)光定输出扭矩的2倍，q且q种加速和减速又q于频繁Q那么最l也?x)减速机断u。考虑到这U情况出现的较少Q故q里不再q一步介l?/p>
