Transmission like this looks really good in a simulation, but I wonder how much lubrication would this require to operate in the real world.

A lot of those solutions have been around for centuries but are quite impractical. The problems are often the required operational tolerances, wear rate, poor torque characteristics and other real life issues.

They are utterly fascinating to watch though.

Someone else made an animation of this in r/mechanicalgifs not long ago, and people brought up the same objection. It turns out, though, that you can buy angled screwdrivers using this mechanism, and they work pretty well.
