The initial torque on the nut tensions the drum against the tapered shaft but this torque relaxes as the drum heats and cools. The drum expands and is pushed onto the shaft. It cools and tightens it's grip on the shaft. Friction is very high after a good heat cycle. The drum does not separate easily from the shaft even with a puller after this occurs.

MoM works just fine. It prevents galling and with the tight fitment the joint doesn't rust. No oxygen. A very light film of anti-seize grease could be used as well.
