Do we need a Chinese visa for this?
NO, both South Korean and Belgian citizens can avail 72 hour-visa-free-transit at Beijing airport.

"Beijing offers 72-hour visa-free transit for foreign visitors with third-country visas and transit at Beijing. Foreign visitors, who hold passports issued by the countries on the 72-hour Visa-free Transit Policy List and stay in Beijing for transit for up to 72 hours, could apply for a visa-free transit stay in China at the immigration inspection authority at Beijing Capital International Airport. This policy is only applicable for foreign visitors who enter into, stay in and leave from Beijing."
Also Timatic confirms the same.
Moreover, you have 1 hour 50 minutes layover time, you and your wife don't need any transit visas. However there is an issue, as you have just commented Asiana lands at T3 and Aerofloat departs from T2 which means you will need to clear immigration and cutoms because distance from T2 to T3 is 8 km. You can take shuttle bus which runs every 15 minutes and would take around 20 minutes for the shuttle bus from T3 to reach T2 at Beijing airport. Please SEE
Therefore, it is a short connection and there is always a possibility 1 hour 50 minutes won't be enough to change terminals.
Any known problems for online checking with Aeroflot?
Please see the following like all major airlines, Aeroflot also has online check in facility which begins 24 hours and closes 45 minutes before departure .

Further there is a warning from Aeroflot:
Attention!
You must have a paper boarding pass in order to board the plane. If you were unable to print your boarding pass at home, you may print your boarding pass at a self-service check-in kiosk at the airport.

Visa-wise you're fine. However, a 1 hour 50 minute connection on separate tickets in Beijing is totally asking for it. I probably wouldn't take the flight even if the tickets were free.
As for the question about which terminal the airlines are in--I don't know and I don't care, the connection is insane, period.
Since you are on separate tickets you can't check your bags through, you will have to clear immigration, recover your bags and then clear customs. You then need to deliver your bags to the new airline then go back through customs, immigration and security. Having to move from one terminal to another is only a small part of the time. I don't know the checkin time limit for Beijing, I know it at least was 60 minutes in Shanghai--and the one time I did it with 65 minutes I would have missed the plane had it departed on time.
Beijing is notorious for connection problems, also--and since you're on separate tickets if you're not fast enough your main ticket goes poof.
Given the separate tickets I would book this with an overnight stay.
