Depends on your hubs... Is there setscrews or some other method of retention? Pics might help...

So... Undo the set screws, and try gently tapping with a mallet, or hammer and block of wood to avoid damage.

try some CRC or WD40 on them
is it rust preventing the removeal?
take the set screws out and put WD40 down the hole
last idea is use a bigger hammer but be sensable at the same time

okay are you talking about a pulley puller and they are for a keyed axle

You could put a hot wrench to it too, but be careful and don't overdo it. Patience is the key to success. I once had to spend about two hours working a tiller tine off it's shaft. And that was after nearly a week of WD40 soaking...

try the puller then the oxy assuming u have either of these
last option is to try and use a punch to knock the key out then get a crow bar and try and turn the hub as this may break the seal that is locking it on

not sure what a hot wrench is and not sure what oxy is

Hot wrench= Propane (plumber's) torch, or oxy/propane, oxy/mapp, oxy/acetylene torch.
Oxy=oxygen
You would gently heat the hub all around, while trying NOT to heat the shaft. This will slightly expand the hub, greatly improving the odds of freeing it without beating it to a pulp.

we are both reffering to the same thing (i think)
an oxygene accetalene torch
or a propane torch

PB blaster works like a charm, you will need to let it soak in and spray it again though. Ive had good luck with the stuff...
Be careful if the hub is aluminum if you torch it, dont take much to mess it up...

If I just said, "torch", you wouldn't have asked what a "hot wrench" is!

oh yeah and if it is aluminium and the axel is rusty it may pay to sweep it down first
although the chance of any reation is so low it is unmeasureable murfeys law says it will

Besides rust someone may have used a over-sized key and hammered your hubs on.
I agree with using a punch to try and drive the key out first, and then using a block of wood to carefully hammer the hubs off.
If they're the split hub designed kinda like the pic below, it sometimes helps to drive a wide straight blade screwdriver into the slot to
expand them a bit. Although it'll leave marks.
Notice this gold hub has an extra set screw that pushes against the key. Make sure dirt isnt just hiding one of the sets screws on your hubs.
