Hammering is not the answer as you will soon have to replace the wheel bearing too because it's also taking a beating. There is so little clearance between the hub and rotor that the rust build-up between the two bonds them together. The only way to get it off without damaging your wheel bearing is to hacksaw or grind it off to release it from its death grip on the hub. You will have to make cuts and then use a chisel in the cuts to break chunks off till it releases the hub. You may have to go as much as half way around before it lets go. I know because I had to do both of mine last summer and had to replace the bearing on the one that I beat on a few months later. Good luck. I hope this helps.
btw: replacing the wheel bearing is not an easy job.
