Problems solved by technology
Since the engine 1 and the generator 3 are structurally independent, the existing fuel generators have defects such as loose overall structure, large space occupation, and heavy weight.
In addition, during actual installation, the coaxiality accuracy of the engine output shaft and the generator input shaft is low. Therefore, the maximum speed of the generator during operation is limited, and it is easy to cause damage to the coupling and even the generator.

The invention discloses a fuel generator. The generator includes a fuel engine and a generator, wherein the generator consists of a central stator and an outer rotor; the central stator is fixed on a engine shell at the side of the output shaft of the engine through the supporting sleeve of the central stator; the outer rotor is sheathed with the central stator from the outer side of the axial direction of the central stator and is fixed on the output shaft of the engine through a central shaft sleeve of the central stator; the supporting sleeve of the central stator is provided with a central through hole for the central shaft sleeve and / or the output shaft of the engine to pass through. The invention has the advantages that the stator of the generator is directly mounted on the engine shell; the outer rotor is directly fixed on the output shaft of the engine, thus partial generator and the engine are formed into an integral structure, reducing the size, leading the structure to be simple, reducing the cost and improving the efficiency.
Description
technical field [0001] The invention relates to a fuel generator. Background technique [0002] Such as figure 1 As shown, the existing fuel generator is usually composed of a frame and a fuel engine 1 and a generator 3 independently installed on the frame, the output shaft of the engine is connected with the input shaft of the generator through a coupling 2, and thus drives the generator Output electric energy outside. Since the engine 1 and the generator 3 are structurally independent, the existing fuel generators have defects such as loose overall structure, large space occupation, and heavy weight. In addition, during actual installation, the coaxiality accuracy of the engine output shaft and the generator input shaft is low, so the maximum rotational speed of the generator in operation is limited, and it is easy to cause damage to the coupling and even the generator. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of ...
