Abstract
The utility model discloses a kind of generating equipment combining structure, comprise engine and generator, the output shaft of described engine is connected by spring coupling with the armature spindle of generator; Described spring coupling comprises and input duplex ring flange and export duplex ring flange, and the second flange of described output duplex ring flange has the first elastic transmission ring section that a thickness is radially reduced to edge gradually by middle part.The utility model is reduced to edge by middle part gradually due to the thickness of the elastic transmission ring section exporting duplex ring flange, 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.
Description
Technical field
The utility model relates to a kind of generating equipment, particularly a kind of combined power generation equipment.
Background technology
Combined power generation equipment, because the weight of its engine and generator is all comparatively large, therefore when assembling the output shaft of engine and the armature spindle centering difficulty of generator comparatively large, easily there is rigging error.
And the output shaft of engine is generally connected by rigid flange dish with the armature spindle of generator in prior art, rigid flange dish does not have the function automatically adapting to rigging error, make power transmission shaft vibrations in transmission process comparatively large, easily occur the problems such as power transmission shaft rapid wear.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of generating equipment combining structure, the problems such as power transmission shaft vibrations in existing combined power generation equipment are large to solve, quick abrasion.
The utility model generating equipment combining structure, comprises engine and generator, and the output shaft of described engine is connected by spring coupling with the armature spindle of generator;
Described spring coupling comprises with input duplex ring flange and exports duplex ring flange, first flange of described input duplex ring flange is connected with the output shaft of engine, first flange of described output duplex ring flange is connected with the armature spindle of generator, second flange of described input duplex ring flange and the second Flange joint of output duplex ring flange, and the second flange of described output duplex ring flange has the first elastic transmission ring section that a thickness is radially reduced to edge gradually by middle part, the maximum ga(u)ge of described first elastic transmission ring section is 4:1 ~ 3:1 with the ratio of minimum thickness.
Further, the second flange of described input duplex ring flange 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 middle part of described input duplex ring flange and output duplex ring flange is provided with lightening hole.
The beneficial effects of the utility model:
1, a kind of generating equipment combining structure of the utility model, the thickness exporting the elastic transmission ring section of duplex 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 generating equipment combining structure of the utility model, by also arranging elastic transmission ring section at input duplex ring flange, thus can further improve the ability that the transmission capacity of spring coupling and automatic makeup fill rigging error, and improve the intensity of spring coupling.
Accompanying drawing explanation

Fig. 2 is the first sectional structure formula schematic diagram of spring coupling;
Fig. 3 is the second sectional structure schematic diagram of spring coupling.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, a kind of generating equipment combining structure of the present embodiment, comprise engine 1 and generator 2, the output shaft of described engine 1 is connected by spring coupling 3 with the armature spindle of generator 2;
Described spring coupling 3 comprises with input duplex ring flange 31 and exports duplex ring flange 32, first flange 311 of described input duplex ring flange is connected with the output shaft of engine, first flange 321 of described output duplex ring flange is connected with the armature spindle of generator, second flange 312 of described input duplex ring flange is connected with the second flange 322 exporting duplex ring flange, and the second flange of described output duplex ring flange has the first elastic transmission ring section 323 that a thickness is radially reduced to edge gradually by middle part, the maximum ga(u)ge of described first elastic transmission ring section is 4:1 ~ 3:1 with the ratio of minimum thickness.
The present embodiment generating equipment combining structure, the thickness exporting the elastic transmission ring section of duplex 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.
As the improvement to the present embodiment, second flange 312 of described input duplex ring flange has the second elastic transmission ring section 313 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.By also arranging elastic transmission ring section at input duplex ring flange, thus can further improve the ability that the transmission capacity of spring coupling and automatic makeup fill rigging error, and improve the intensity of spring coupling.
As the improvement to the present embodiment, the middle part of described input duplex ring flange and output duplex ring flange is provided with lightening hole 4, arranges lightening hole 4 and can save ring flange manufacturing cost.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
