为了防止减速电机启动时发生故障,在投入运行前请做好以下检查工作:
一、检查定子电源线是否完好,引出线连接是否牢固。
二、检查减速电机保护接地(接零)线是否完好,连接是否牢固。
三、检查减速电机内外有无污垢和杂物,用压缩空气或吸尘器等除尘清扫。
四、检查各机械部分、螺栓、地脚螺丝、端盖等是否牢固,减速电机安装必须稳固。
五、检查减速电机与被带动机械的靠背轮联结是否牢固,减速电机传动皮带的张力是否适当。
六、检查减速电机电源开关、启动设备以及控制装置是否合适、完好,丝是否符合要求,热续电器调整是否适当。
七、检查绕线型减速电机转子滑环或换向器与电刷接触是否良好,电机牌号是否符合制造厂说明书的要求,电机压力是否适宜,电机在机架中是否适合,提升是否灵活。
八、对于新投入使用的减速电机,应检查电机铭牌电压、频率是否与电源一致,其他参数(如功率、机座号等)是否满足要求。如果对新投入使用的减速电机的情况不堪了解,进行一次解体检查,尤其要检查轴承内是否有适量的润滑脂。
九、对于新投入使用或停用3个月以上的减速电机,应用500V兆欧表测量其绝缘电阻。低压减速电机定子绕组的绝缘电阻在常温下不得低于0.5M/KV,高压减速电机则不得低于1M/kV。达不到此要求者,应查出原因并进行处理。如为受潮引起,应作干燥处理。

主要原因包括:使用前过早打开轴承包装,造成污染;轴承的工作环境不清洁,工作介质污染;安装时工作环境不清洁,造成污染等。疲劳破坏是轴承常见的损坏方式。常见的疲劳破坏的原因可能是:轴承长期超负荷运行;维修不当;未及时维修;设备老化等。安装不当也会导致轴承出现问题,安装有偏差或未装到轴承位,造成轴承游隙过小。内外圈不处于同一旋转中心,造成不同心。安装时力度过猛,其中用锤子敲击轴承对轴承伤害是的;也是造成变形的主要原因。
