风力发电机组齿轮箱轴承养维护

2009-04-21 来源:中国风电材料设备网 浏览数:5463

  通过下列参数对比可以看出齿轮箱损坏前后,运行温度变化较为明显。运行人员发现温度异常后登机检查发现机组运行噪音变化不是非常明显,但中箱体行星架处温度明显偏高,滤清器内有2mm2左右的鳞片状铁屑和大量金属粉末。后对该机解体后发现,高速轴轴承损坏后齿轮位移,导致行星架齿面啮合异常而损坏。

  由此可见,在风电机组的日常运行中,对齿轮箱运行温度的观察比较,对维护人员及时准确地掌握齿轮箱的运行状态的改变有着较为重要的意义。

2.3齿轮油位低

  常见故障原因:齿轮油位低故障是由于齿轮油低于油位下限,磁浮子开关动作。
