On IFR training flight in level cruise when aircraft engine started to violently shake. Requested vectors for nearest airport to rockford approach. Rockford then turned us and asked if we could make a frequency change (nearest airport was in chicago's airspace). I contacted chicago, declared an emergency and was vectored to 'case de aeronautical' airport, was unable to find (I believe lights were non on private strip). Proceeded approximately 8 mi to an airport with a beacon, 'lndgs' airport, and was able to make a safe landing.
