堵转转矩倍数大一些有好处,尤其是大电机一般自身的转动惯量都比较大,如果堵转转矩倍数比较大则电机起动更加迅速,转动也更自如。但是堵转转矩倍数也不能越大越好。 两个转矩倍数越大,电机的起动电流一般情况下也会增加很多,对电网的冲击也会越大,所以一般选择电机的时候,要根据实际工况的要求,选择合适的数值保留一定裕度即可。一般情况下堵转转矩倍数选择1.8--2.2。转矩倍数选择2.0-2.8(根据电机大小的不同而不同)。 由于电机静转矩的存在,在对电机进行特殊操作前,务必先将电机断电,否则强行操作时,容易损坏电机齿轮箱的齿轮。 为降低电机输出轴转速,由众多齿轮组合成为齿轮箱。 8、减速机额定转矩/工作转矩:减速箱在正常工作状态下,承受允许负载时所输出的转矩。 9、减速机容许转矩/极限转矩/损毁转矩:虽然减速机的出力转矩与减速比成比例,但齿轮的材质等其他条件(例如齿轮模数大小)对容许转矩有所限制,这就是转矩。每个齿轮箱都有一个极限扭矩,称为损毁扭矩,若过大的外力产生的扭矩作用于齿轮箱,将会引起齿轮的破坏。

减速机是一种动力传达机构,利用齿轮的速度转换器,将电机(马达)的回转数减速到所要的回转数,并得到较大转矩的机构。在目前用于传递动力与运动的机构中,减速机的应用范围相当广泛。常见问题及其原因:减速机发热和漏油蜗轮磨损传动小斜齿轮磨损轴承(蜗杆处)损坏减速机发热和漏油蜗轮减速机为了提率,一般均采用有色金属做蜗轮,采用较硬的钢材,由于它是滑动摩擦传动,在运行过程中,就会产生较高的热量,使减速机各零件和密封之间热膨胀产生差异,从而在各配合面产生间隙,而油液由于温度的升高变稀,容易造成泄漏。
