Single-bearing permanent magnet synchronous generator equipped with elastic connection disc and used for diesel generating set

The utility model relates to a single-bearing permanent magnet synchronous generator equipped with an elastic connection disc and used for a diesel generating set. The single-bearing permanent magnet synchronous generator comprises a generator shaft and is characterized in that the shaft extending end of the generator shaft is connected with a diesel oil engine through an elastic connection disc. The advantages are that the elastic connection disc is adopted to connect the diesel engine and the generator, so vibration of the diesel engine can be absorbed, the service life of the generator is prolonged and the vertical length of a connection device is minimized; and furthermore, without a bearing at the shaft extending end, the size of the generator is reduced and the overall size of the permanent magnet synchronous generator used for a diesel generator is then reduced, such that convenience is provided for arrangement of all power parts in a vehicle.
