减速机技术资料：

减速机转轴是减速机的重要零件之一，它是传递扭矩、带动机械负载的主要部件。减速机轴必须有足够的机械强度和刚度，才能完成减速机功率的传递，使减速机运行时不发生振动或定子、转子相擦。

轴常见的损坏现象有：转轴弯曲、轴颈磨损、轴裂纹和轴断裂等。其损坏原因，除制造质量本身有问题外，大多数是使用不当造成的。例如，拆卸皮带轮时，不用工具而硬敲，再加上敲打时受力不当，极易引起轴的损坏。

1．转轴弯曲的修理转轴弯曲会造成减速机气隙不均，产生振动和噪声。

若弯曲不大，为了消除弯曲对转子铁芯段的影响，可以磨光轴颈、滑环和换向器等。在小型异步减速机中，也可以磨光转子的铁芯段，但转子与定子间增大的间隙值不应超过正常间隙的10％。

如果轴的弯曲值很大，以致不能用加工轴颈和轴上零件的方法来消除，可在压力机上矫正，或用电焊机在弯曲处表面均匀堆焊一层，然后上车床，以转子外圆为基准找出中心，车成要求尺寸，并用百分表检查。

用敲打法矫正用冷态直轴法矫正转轴的弯曲示意图

2．轴颈磨损的修理轴颈磨损由于轴承内圈与轴颈的配合过盈过小，在运行中发生轴与内圈相对运动，使轴颈磨损而松动(即走内圆)。这时，必须将轴颈修补到原来尺寸。常用的修补方法有下列几种：

方法～：喷镀或刷镀。利用专门的设备将金属镀在磨损的轴颈上，再磨削到需要的直径。此法适用于磨损深度不超过0．2毫米的情况。

方法二：补焊。将转轴放在带滚轮的支架上，用中碳钢焊条进行手工电弧焊，从一端开始，一圈一圈地补焊，边焊边转动转子，直至将轴颈全部补焊完毕。冷却后，放到车床上加工到所需尺寸。加工时，注意校正两轴颈与转子外圆的同轴度。

方法三：镶套。当轴颈磨损较大或局部烧损发蓝退火时，可将轴颈车圆上后，放在车床上加工套的外圆。

3．轴裂纹或断裂的修理对于出现裂纹的轴，若其裂纹深度不超过轴颈的10％～15％、长度不超过轴长的10％(对纵向而言)或不超过圆周长的10％(对横向而言)，可用堆焊法进行补救。

对于裂纹大或断裂的轴，必须更换新轴，换轴时，小型减速机一般用35号钢或45号钢。换轴一时有困难，在不影响轴质量的前提下，也可采用补接法
