曲轴减振器位于机器后部、发动机前面。

减振器损坏或减振器有故障会增大扭转振动。 这种振动会导致曲轴及发动机其他部件损坏。 损坏的减振器会在发动机的转速范围内的不同点引起齿轮系噪声过大。

如有下列任一原因,卡特彼勒建议更换减振器:

  • 发动机发生了曲轴断裂的故障。

  • S·O·S 分析查出曲轴前轴承磨损。

  • S·O·S 分析查出不是由于缺油而引起的齿轮系大量的磨损。

如果没有任何上述情况或减振器没有损坏,则减振器可以再使用。

检查减振器组件外壳有无凹痕。 外壳上的凹痕可能造成减振器组件故障。 如果减振器损坏,安装一个新的减振器。

参考关于被维修机器更换曲轴减振器的资料,参阅拆解和组装, "减振器" 。
