Described spring coupling comprises input shaft flange plate and output shaft ring flange, described input shaft flange plate coaxially arranges with output shaft ring flange and is fixedly connected with at edge part, described output shaft ring flange has the first elastic transmission ring section that a thickness is radially reduced to edge gradually by middle part, and the maximum ga(u)ge of described first elastic transmission ring section is 4:1 ~ 3:1 with the ratio of minimum thickness;
Be provided with the bellmouth with engine output shaft secure fit in the middle part of described input shaft flange plate, described bellmouth taper seat is provided with annular oil groove; The serves with generator rotor shaft spline fitted is provided with in the middle part of described output shaft ring flange.
Further, described input shaft flange plate has the second elastic transmission ring section that a thickness is radially reduced to edge gradually by middle part, and the maximum ga(u)ge of described second elastic transmission ring section is 4:1 ~ 3:1 with the ratio of minimum thickness.
Further, the rubber alloy pad for isolating engine output shaft and generator rotor shaft is provided with between described input shaft flange plate and output shaft ring flange.
Further, described rubber alloy pad comprises body of rubber and the spring becoming annular to be embedded in body of rubber.
The beneficial effects of the utility model:
1, a kind of combined power generation device of the utility model, the thickness of the first elastic transmission ring section of output shaft ring flange is reduced to edge gradually by middle part, make it strain can occur under circumferential torsional moment effect, and then make this spring coupling can Automatic adjusument and compensate manufacture, assembling and driving error, transmission shock is little, strong adaptability, the accuracy of manufacture and assembly difficulty can be reduced simultaneously, improve the assembly working efficiency of Blast Furnace Top Gas Recovery Turbine Unit (TRT), avoid rigging error to cause damage to engine and motor.
2, a kind of combined power generation device of the utility model, by arranging the second elastic transmission ring section in input shaft flange plate, thus can further improve the ability that the transmission capacity of spring coupling and automatic makeup fill rigging error, and improves the intensity of spring coupling.
