Tilt pad bearings: industry std, test specification, guideline etc.

[ginsoakedboy]

Can anyone point me to an industry standard or test specification or even a guideline on how to define a qualification and/or performance test regimen for a set of tilting-pad (thrust and axial) bearings?

I need a generate a document that details or at least outlines such a test protocol.

Rock Qualification Protocol

Place Rock, Test Article #1, on firm ground, or, preferred, much larger rock. Refer to Mil Std #1, "Identifying What is a Rock".

Drop Rock, Test Article #2, on Rock, Test Article #1.

Unbroken Rock becomes new Test Article #1.

Recurse until you run out of Rocks.



Seriously, find a qualification protocol that makes sense, and adapt it for the design requirements of your set of stuff.

Mike,

I am new to bearings in general. Any help with identifying an appropriate list of tests will be great.

Who decided you needed tilting pad bearings?

That person/team should have a pretty good idea of how to verify that you got what you ordered. Some of that should be referenced by the purchase documents.

The application requires high performance bearings. No one in my company has any experience with bearings. There is no PO yet. The idea is to develop a set of bearings with a mfr. I do not want to rely on the manufacturer to inform what testing needs done.

Mike, looks like you are familiar with this stuff. Where can I get the info I need?

"High performance" means different things to different people.

If you could reveal some of the performance requirements here, maybe someone could help. I'm shooting in the dark.

I assume you are not trying to verify the design, only verify quality of a received product?

Before installation some thoughts about things to look at
Also babbit bond can be checked by UT examination. You can perhaps do a scan of the materials to verify expected material composision.

Also could include conformance to dimensional and particularly exact radius-of-curvature requirements.

During installation you can expected check clearances and lift.

When the machine starts up you can check temperature, vibration.

Just some thoughts.

I AM looking to verify the design. Additionally, I will need to verify the suitability of the received product as well.
