Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

See generating set shown in Figure 1, comprise the motor 1 that drive unit is selected for use, its output is connected with driving wheel 4 in the one-level drive system by clutch 2, shaft coupling 3; This driving wheel 4 connects and composes the one-level drive system by belt and driven pulley 5.Driven pulley 6 in the secondary driving system is installed on the driven pulley 5 in described one-level drive system coaxial, is connected and composed secondary driving system by belt on it and the driven pulley 7 that is installed on the speed increaser 8.Described speed increaser 8 is connected with generator 10 by shaft coupling 9.

In above-mentioned, an auxilliary driving wheel is installed, in order to increase torsional interaction in a coaxial side of described driven pulley 6.

What in the present embodiment, drive unit was selected for use is exciting motor 1.In addition, also can select permanent magnet motor or diesel engine for use.

Fig. 2 has provided the embodiment different with Fig. 1, have and on Fig. 1 architecture basics, done corresponding change, be that speed increaser 8 opposite sides are connected with another generator 20 by shaft coupling 19, the clutch of installing 21, promptly the both sides of speed increaser 8 connect two generators, and generating is used to have holidays by turns.In like manner, driving wheel 4 opposite sides in described one-level drive system are connected with another motor 11 by shaft coupling 13, the clutch of installing 12, and promptly the both sides of driving wheel 4 connect two motor, and driving is used to have holidays by turns.

Except that selecting motor for use, be suitable for selecting for use diesel engine equally in above-mentioned.

Be the effect that proves absolutely that the utility model reaches, be illustrated by a concrete application example.

Select 12 horsepowers (1 horsepower=75 Kilogram-Meter Per Seconds), 1500 rev/mins diesel engine, promptly 1500 rev/mins/60 seconds=25 revolutions per seconds for use according to application example; 900 kilograms of the power of 12 horsepower diesel per seconds (12 horsepowers * 75 Kilogram-Meter Per Seconds=900 Kilogram-Meter Per Seconds), i.e. 900 Kilogram-Meter Per Seconds/25 revolutions per second=36 kilograms, promptly the shaft power revolution of diesel engine is 36 kilograms; Selecting driving wheel 4 external diameters for use is 120 millimeters, and the diameter of axle is 50 millimeters, 120 millimeters/50 millimeters=2,4 times, and 36 kilograms of ÷ 2.4=15 of diesel engine shaft power revolution kilogram, promptly diesel engine passes to driven pulley 5 with 15 kilograms of revolutions by belt.The external diameter of driven pulley 5 is 800 millimeters, is 6.66 times of 120 millimeters of driving wheel 4 external diameters; So the rotating speed of driven pulley 5 is 1500 rev/mins of ÷ 6.66=225.2 rev/mins; The internal diameter of driven pulley 5 is 42 millimeters, and promptly 800 millimeters ÷ 42 millimeters=19 times, and therefore, driven pulley 5 has enlarged 19 times to 15 kilograms of diesel engine revolution; And speed becomes 225 rev/mins by 1500 rev/mins; This driven pulley 5 and driven pulley 6 run-in synchronisms, but the external diameter of driven pulley 6 is 430 millimeters, internal diameter is 42 millimeters, promptly 430 millimeters ÷ 42 millimeters=10.23 times; Driven pulley 6 19 times that driven pulley 5 is enlarged have reduced by 10.23 times, so 19-10.23=8.77 doubly, i.e. and 15 kilograms * 8.77=131.55 kilogram; So driven pulley 6 passes to driven pulley 7 by belt with 131.55 kilograms.The external diameter of driven pulley 7 is 980 millimeters, and speed increaser 8 internal tooth pitch diameters are 90 millimeters; So, 90 millimeters=10.88 times of 980 millimeters ÷, and the external diameter of driven pulley 7 is 430 millimeters=2.279 times of 980 millimeters ÷ of driven pulley 6,225 rev/mins of driven pulley 6 pass to driven pulley 7 speed and have reduced by 225 rev/mins of ÷ 2.279=98.72 rev/mins, but moment of torsion has enlarged 10.88 times, promptly is delivered to 131.55 kilograms * 10.88=1431.26 of the moment of torsion kilogram of speed increaser 8 internal tooth pitch diameters; And the multiple of speed increaser 8 is 1: 16, be that driven pulley 7 is goed around, the output shaft of speed increaser 8 changes 16 and changes, learn by above-mentioned, the rotating speed of driven pulley 7 is 98.72 rev/mins, the output shaft rotating speed of speed increaser 8 is 98.72 rev/mins * 16=1579.52 rev/min so, but moment of torsion has descended 16 times, i.e. 1431.26 kilograms of ÷ 16=89.45 kilograms; The rotating speed that generator shaft is accepted is 1579.52 rev/mins, and the power of revolution is 89.45 kilograms.Generator is selected 22 kilowatts for use, and (1 kilowatt=1,36 horsepower) i.e. is (22 * 1,36 * 75) ÷ 25=89,76 kilograms.And the power of above-mentioned generator revolution is 89.45 kilograms, and promptly 89,76 kilograms-89.45 kilograms=0.3 kilogram, both differ 0.3 kilogram.Change if the revolution of diesel engine is raised 10, promptly diesel engine be 1510 rev/mins just fully passable, because of the diesel engine maximum speed is 2000 rev/mins.
