Hello,
Being moved out of my material comfort zone and into fluids after a job change; and in need of some basic advice.
we have a pneumatic driven oil unit that can develop 700b and a flow rate of 5.3cc/stroke. The cylinder that is being supplies is a double acting design 2" bore and 1"...

Following on from this earlier thread, I am also looking to replace our ageing and unsupported software with something I can link DC/AC motor/generator design created in solid-works - this is not an immediate purchase, more a toe in the water !
Ansoft Maxwell looks to have the...
Hi chaps,
I'm in a struggle - we have a large vertical pump/storage unit and the bottom guide bearing is loosing oil out of the upper seal, by how much no-one knows but the feeling is quite a lot - technical reporting at its best!
We're going to re-set the seals clearance back to design...
Morning all (or afternoon depending on your time zone :-) )
I have an old exciter in the workshop that has come in with wiped bearings, after some extensive research with the owner we've found that the bearings were originally lemon bore but were machined over years as a plain bearing - but no...
Hello all,
not sure where this topic falls, but it is related to vibration - well kind of!
What happens to the torque figure for a Cleveloc nut compared to a std full nut?
I would expect it too reduce since the elliptical collar will increase the torsional load on the bolt, but by how...
Hello Guys,
I've been sent through some photographs that show odd longitudinal marking on the journals and bearings :-( I suspect that they're caused by the journal roundness, but would appreciate any views (apologies for the quality of the photographs)
Thanks
Tony.

We have a simple spreadsheet that we log memos and other similar documents in and with some code to open these documents in word - and we're looking to see if we can have something similar for opening drawings saved in a PDF format. Unfortunately the code was written by a chap who has moved on...
Hi Guys,
Havening not been involved in vibration for a few years, suddenly it’s creeping its way back into my life :-o
I used to have a link to some ‘standard’ orbit patterns, but having changed ‘puters a few times its been lost – would anybody have a similar link they could share ?
Many...
We have a small motor that has been repaired a few times by our sister companies, and to cut a long story short; it's ended up on my lap (very uncomfortable!).
The bearings seats are undersize by 0.6mil (0.017mm) for both 6217 & NU217. Is this loose enough to cause a higher than expected...
Just to easy my mind, not easy because there is not a lot left;
It's not a welding process and I don't think that its an electroplating process - so what is it?
Any ideas.

I trying to calcule the torsional stiffness of rotor, the construction is a simple rolled bar with 6 arms welded down the rotor body.
Is there an equation for the Polar moment for this type of rotor construction?
Help
