蜗轮蜗杆减速机使用过程中，经常遇到减速机运转时发热的情况。造成内部蜗轮蜗杆的快速磨损。一旦发现发热严重情况，请立即停止工作，找出蜗轮减速机发热的原因并进行排除。因为蜗轮减速机一旦发热严重就会使蜗轮与蜗杆的耐磨系数下降，致使减速机内部件很快磨损。
以下是蜗轮减速机发热的常见故障原因和一般的解决办法：
一、传动装置固定不良,蜗轮磨耗或损伤,轴承磨耗或损伤,螺栓松脱,异物侵入
解决方法:固定传动装置,更换蜗轮,更换轴承,拧紧螺栓,去除异物并更换润滑油漏油
二、油封损伤,密封垫破损,油量过多,油塞松脱,油标破损
解决方法:更换油封,更换密封垫,加入适量润滑油,拧紧油塞,更换油标入力或出力轴不转
三、蜗轮蜗杆过热,轴承损坏,异物侵入,蜗轮、蜗杆过度磨损
解决方法:更换或维修,更换轴承,去除异物并更换润滑油,更换蜗轮或蜗杆蜗轮过度磨损
四、超负何运转,润滑油不良或不适当,润滑油不足,轴承磨损,运转温度过高
解决方法:调整至适当负何,更换适当润滑油,依指示加入适当润滑油,更换轴承,改善通风环境
五、超负荷运载,润滑油过少或过多,润滑油不良或不适当,油封过度摩擦,出力轴与传动装置连接不当
解决方法:调整至适当负荷或选大机型,依指示加入适当润滑油,油排出后加入适当润滑油,在油封处滴数滴润滑油,调整至适当位置减速机杂音
六、蜗轮、蜗杆啮合不良,轴承损伤或间隙过大,润滑油不足,异物侵入
解决方法:修整齿接触面,更换轴承,依指示加入适量润滑油,去除异物并更换润滑油
