I Know how to diagnose the fault, but I'm curiosu to why the locked coupling, I have seen the analogy described many times when people are critqing nspectre.

Yes It was some combo of speed multiples, gee it was a long time ago--20+ If I get some spare time next week as it looks like I can maybe find the actual logic description, it was readily available. I can say I can't find a locked coupling from spectrum data either but if it give hi bearing condition w/o any fault freq.'s then we are talking depending on coupling......

markL, SKF does still have AppEng around the world providing real life experience to our SW engineers. I like to think we are making more user-friendly informative products to meet our customer's ever changing demands.

Some of you may recall that SKF introduced our Decision Support AI way back in the late 90's, but it seems not too many customers here in the US of A want to input all the necessary data to make it useful. We use it internally to cut down on analysis time as suggested.

Shoot, some customers forget they have an analyzer within 5yrs of buying one.

Oh yes y did, it came with buying Palomar and getting Mr Moore in the package it did.... He fixed that. You were hooked on SEE or what the name was at the time, you see I was there at the time or rather here so I know in detail so no you know like that, it was not specific US either........
If customers lost their boxes after a couple of years may be in  connection with.
A. customer support and improving and enhancing technology
B. Change of staff, leader, trail blazer loose blaze, get relocated etc etc retired.
C. New management have different ideas
D. Plant get bought, sold, bankrupt,  downsized
E. PDM may be put on sell and buy and operations may not select to buy PDM...
etc etc
it may not be in the hand of the enduser as y put it he may no longer get resources to do the work........

I have seen so many programs go down the cracks it aint no fun! Believe me it is a serious wast of money and work when it goes south.

Hi Tom,
I am working fairly close with guys in Livingston on the new product, I was always wondering what happened with the decision support product, I use the regular @ptitude connect at the moment.

A sudden increase in 1X in a machine that is not likely to thrown out of balance, with all bolting tight, with a gear coupling installed, is likely a “locked coupling.” I’ve seen it on a Hoffman blower - grease in the coupling was so old and hard, we had to beat the outer covers back with a hammer (easy now... a soft face, dead blow hammer).

agree trend is key, I've found 1x or 2s dominant with locked coupling, but if you are called to diagnose for the first time my first its very tricky, personally i made them to solo run the motor, and inspect coupling now that is disasembled XD
