Turbine Bearing - Babbitt failure

Turbine Bearing - Babbitt failure

Turbine Bearing - Babbitt failure

(OP)
Lots of fragments of the babbitt, some popped out.  The fracture surface of the babbit looks like a fatigue surface and there is not a lot of smearing.  Metengr made mention in an old posting of babbitt fatigue (see thread605-155979: Generator rotor and TG bearing to ground isolation ) and this sound like what he describes.  Can anyone provide information/list reference books that would help me find my way?

Thanks.

RE: Turbine Bearing - Babbitt failure

If you have access to EPRI documents, here is the one you need;

EPRI  "Manual of Bearing Failures and Repair in Power Plant Rotating Equipment" GS-7352  July 1991

excellent.  I keep forgetting that EPRI is far more than just boiler tubes.  I do have access and I was able to download the file.  There is peace and tranquility in the metals lab today (or at least, at the moment).

RE: Turbine Bearing - Babbitt failure

EPRI will appreciate your saying that.
