曲轴减振器限制了曲轴的扭振。 粘液减振器有一个置于充满液体的壳体内的重块。
曲轴减振器损坏或曲轴减振器出现故障会增加扭振。 扭振会损坏曲轴和其他发动机部件。 老化的减振器会在某个转速范围内的变化点引起齿轮系噪声过大。
减振器灼热可能是过多磨擦的结果。 这种摩擦可能是由于没有对中导致。 运行中,利用红外线温度计监测减振器的温度。 如果温度达到
减振器利用发动机机油进行冷却。
检查减振器有无凹痕、裂纹和机油泄漏迹象。
如果存在机油泄漏迹象,检查密封。
针对下述任何原因更换减振器。
- 减振器有凹痕、裂纹或其他损坏。
- 减振器上的油漆因受热而变色。
- 发动机曾发生因曲轴断裂而引起的故障。
- 曲轴轴承出现过度磨损。
- 齿轮传动系有并非因缺少机油而造成的的大量磨损。
有关减振器更换的信息,请参阅维修手册或咨询 Cat 代理商。
