gearbox vibration monitoring

gearbox vibration monitoring

(OP)
A supplier has suggested that permanently mounted vibration sensors should be attached to the baseplate.
I think they should be mounted higher up on the gearbox to a rugged feature like a bearing boss.

Comments?

thanks

RE: gearbox vibration monitoring

What vibration are you trying to measure? Normally transducers are looking at shaft vibration and are mounted as an X-Y pair oriented at 90 to each other. This looks more like overall vibration of the structure itself.

RE: gearbox vibration monitoring

The closer you can mount them to the part of interest the better. Like Scotty said they are usually mounted close to the bearings so you can better monitor bearing and gear vibration. If you mount the accelerometers in the middle of the case for example you can run into funny readings due to case flexure.

And I agree that the two locations are just looking at overall vibe levels. You will probably have a hard time catching a failure in the beginning stages, but at some point it will get bad enough! Depends on what you need and/or want.
