The present invention constitutes like this: electromechanical integration permanent-magnetic outer rotor generator, be integrated by engine and generating equipment, and described generating equipment is by generator unit stator and be positioned at the peripheral concentric generator amature of generator unit stator and form.On the axle bed of engine power axle, be that the center is provided with location hole with the engine power axle; On generator unit stator, the relative position that is positioned at described location hole is provided with through hole; Standing screw screws in location hole by through hole, and generator unit stator is fixed on the axle bed, and the engine power axle is positioned at the axle center of generator unit stator.Described generator amature is made up of external rotor permanent magnet body and outside generator amature outer cover, and generator amature is fastened on the engine power axle by trip bolt, and making engine power axle and generator amature drive power shaft is same axle.
Technical scheme key of the invention process is:
1. utilized the engine power output shaft of Blast Furnace Top Gas Recovery Turbine Unit (TRT) coupling to drive power shaft dexterously as generator amature.
2. utilize the engine power output shaft of Blast Furnace Top Gas Recovery Turbine Unit (TRT) coupling to make and be the generator amature bearing.
3. the motor body that has utilized the Blast Furnace Top Gas Recovery Turbine Unit (TRT) coupling is as generator unit stator winding fixed support.
4. utilized the screw installing hole on the motor body of Blast Furnace Top Gas Recovery Turbine Unit (TRT) coupling to fixedly mount location hole as generator unit stator.
5. utilize the generator permanent-magnetic outer rotor to cover on the generator customization coil windings, substituted the guard shield of generator.
The invention has the advantages that:
1. the power output shaft of engine and generator amature driving shaft are same axle, and the dynamic power machine output shaft of the rotor of generator and driving directly is connected, and has saved traditional moment transmitting device (belt, gear, chain, universal joint, tooth bar, power transmission shaft ...), the generator manufacturing is simple.
2. motor body is as the holder of generator unit stator, and the stator coil winding directly is fixed on the engine body; Generator p-m rotor outer cover is positioned on the electricity generator stator coil winding, as the guard shield of generator.Saved bearing and bracing frame, saved stator support, bearing, and shell have saved the generator protection housing.Reduce generator and made parts, alleviated generator weight, dwindled the generator volume.Because without chassis bracket, stator winding coil insulation, good heat dissipation effect, generator amature do not have bearing also stopped bearing operation damage cause sweep the hall friction with stator winding, reduce the generation of mechanical breakdown hidden danger, improved the functional reliability of Blast Furnace Top Gas Recovery Turbine Unit (TRT) greatly.
3. generator amature directly is fixed on the engine power output shaft and engine power output shaft rotates cutting magnetic line synchronously and produces electric energy, has saved the intermediate power transfer device, and machinery driving efficiency has effectively reduced energy resource consumption up to nearly 100%.
The invention provides a kind of energy-efficient, easy for installation, compact conformation, volume is little, and is in light weight, saves cost, uses simply, maintaining is simple, generating efficiency height, the Blast Furnace Top Gas Recovery Turbine Unit (TRT) of the electromechanical of long service life.
