Apologies for straying OT but the wheels on one of my child buggies does /look/ like a bike wheel.
The rear wheels are mounted on a flanged stub axle (denoted by xxxx below). The hub shell (/,\,_ and - below) is retained by a nut (N) and thrust washer (W). There is a retaining washer (l) which sits inside the end of the hub shell and behind which I can just see some (dry as a bone) ball bearings (b). By smearing grease around the gap between the axle and the retaining washer I was able to get a little into the bearing race but i cannot see how to disassemble the bearing to repack it. Does the panel think it is likely to be non-user serviceable (and therefore potentially needing a new wheel or at least a new hub)? or is there a trick I am missing. The buggy is an alurax in case anyone has one and has doen this already

Why not pour some car engine oil or thick gearbox oil through the gap when the wheel is on its side.
Leave it overnight on some newspaper to let the excess leak out.
According to your excellent graphics you should be able to pull the wheel of the axle after undoing the nut.
Alternatively if you could succeed in drilling a small hole in the hubshell you could repack the bearings with a greasegun
not quite excellent enough and now edited to show why removing the axle doesn't help. uuuu is part of the bearing race seems to be tha part that actually sits against the axle and is fixed wrt the axle. I think the trick would be to somehow pop out the retaining washer 'l'. I will try the engine oil or drilled grease port ideas out
These sorts of wheels very often don't have any grease in the bearings - after all they don't go very fast and so don't generate much heat. The purpose of greasing bearings is not to make them slide - they're supposed to roll not slip - it's to conduct away any excess heat. You say you can see the bearings are dry, which would suggest there's a gap, so if you do grease them, any grit that gets in through the gap will stick.
Can you go to a shop and have a look to see if a brand new one has grease in the races?
