Embodiment
Below with reference to accompanying drawing, the specific descriptions of optional mode of execution of the present utility model have been provided.Below will be that example is described with the generator, but the utility model can be applied on the motor fully.For fear of repetition, will be that example describes with the generator only below.
As shown in Figure 1, generator 1 comprises support 2, stator 4, rotor 5 and cooler 6, and rotor 5 is arranged on the rotor shaft 3.In addition, at rotor shaft 3 wind-guiding Balance discs 10 are installed, and wind-guiding Balance disc 10 is placed the two ends of rotor 5, to play the effect that makes the rotor smooth operation.Simultaneously, wind-guiding Balance disc 10 is provided with passage, allowing such circulate of air-flow shown in the dotted arrow A among Fig. 1 of generator inside, thereby to the cooling of ventilating of generator inside.
Fig. 2 to 4 illustrates the structure according to a kind of wind-guiding Balance disc of the present utility model.As shown in Figure 2, wind-guiding Balance disc 10 comprises outer shroud 11, central ring 12, interior ring 13 and a plurality of blades 14 between outer shroud 11 and interior ring 13 that set gradually from outside to inside.In order in installation and debug process, to realize balance and the centering of rotor, can a plurality of mounting holes 15 be set at outer shroud 11, central ring 12 or interior ring 13, be used for when doing dynamic balancing, installing equilibrium block.The quantity of blade 14 for example can be eight, and is perhaps more or less; The quantity of mounting hole for example can be 16 or still less or more, and these all depend on shape, rotating speed, the position of mounting hole, the structure of generator inner space of blade etc.Only show the situation that mounting hole 15 is set at central ring 12 among Fig. 2, but the utility model is not limited thereto, mounting hole 15 can also be arranged on outer shroud 11, the interior ring 13 or on the combination in any of outer shroud 11, central ring 12 and interior ring 13.
In one embodiment, wind-guiding Balance disc 10 can and be welded by the hot rolled steel machining, thereby provides powerful centering to support and fastening installation function for the rotor tip coil.
In addition, by a plurality of blades 14 are set, can connect on the one hand and support outer shroud 11, central ring 12 and interior ring 13, can in rotor, produce axial air and flow, thereby increase draft by the rotation of rotor shaft on the other hand, reduce temperature of rotor.For example, after a kind of process was calculated in the structure of simulation, used this wind-guiding Balance disc, the increase of rotor ventilation air-flow was about 5% of total ventilation heat exchange throughput.Simultaneously the generator temperature rise can be reduced about 5%.According to the basic theories of electric rotating machine, generator is under nominal situation, and the length of rotor iron core is more short, then produces more few cooling air quantity.By this wind-guiding venting plate is installed, will force motor internal to ventilate and circulate, adopt shorter iron core and produce unnecessary heat thereby offset an electricity machine.If rotor core length shortens, the stator iron core length that then corresponding meeting brings shorten and generator on the minimizing of other component of machine length dimensions, as support, rotating shaft etc.For motor generally speaking these can bring the saving of cost of material.
In one embodiment, a plurality of blades 14 can be welded between three rings equably, thereby enough coil end face support strengths can be provided.In structure shown in Figure 2, blade 14 is used for outer shroud 11, central ring 12 and interior ring 13 are linked together, but the utility model is not limited thereto, and outer shroud 11, central ring 12 and interior ring 13 also can link together by other structures beyond the blade 14.
As illustrated in Figures 5 and 6, blade 14 is by the structure of one flat plate through repeatedly being bent to form, and it comprises first portion 141, second portion 1421, third part 1422, the 4th part 1431 and the 5th part 1432, and at blade 14 opening 144 is set.As shown in Figure 6, can form angle α between first portion 141 and the second portion 1421, can form angle β between second portion 1421 and the 4th part 1431, angle γ can be formed between first portion 141 and the third part 1422, angle theta can be formed between third part 1422 and the 5th part 1432.The size of angle α, β, γ and θ can design according to concrete demand.For example in one embodiment, angle α, β, γ and θ can be in the scopes of 5 to 30 degree, for example 10 degree, 15 degree or 20 degree, and angle α, β, γ and θ can be mutually the same, and be also can part identical, can also differ from one another.Be noted here that these angles of α, β, γ and θ are to describe with the supplementary angle form of the actual angle between the appropriate section.In addition, second portion 1421 can be identical with 1422 width, also can be different, namely can be bent to form structure shown in Figure 6, structure shown in also can being bent to form by three times or four times by twice.The width of opening 144 corresponds essentially to the thickness of central ring 12, in order to the opening 144 of blade 14 can be enclosed within on the central ring 12 when mounted, via welding blade 14 and central ring 12 is linked together then.The plane at first portion 141 places can form certain included angle with the plane at central ring 12 places, and the scope of angle can be adjusted and design according to concrete demand.In one embodiment, this angle for example can be in the scope of 5 to 45 degree.
Aforesaid simple in structure easy-to-use, thus the complexity of assembling not only can not be increased, but also can improve the ventilation cooling effect of generator, reduce the cost of generator.
Should be appreciated that Fig. 5 and Fig. 6 have described a kind of structure of blade 14 in an exemplary fashion, still, protection domain of the present utility model is not limited thereto.For example, blade 14 can also adopt the form of whole bent plates, and perhaps the opening 144 in the structure shown in Figure 5 can be the form of through hole, thereby entangles central ring 12 fully.In addition, blade 14 also can be by one flat plate through once, twice, three times, four times or more times structure that is bent to form, depend on concrete structure and to the requirement of cooling effect.
Though illustrate and described the utility model with reference to some preferred embodiment of the present utility model, but it will be appreciated by those skilled in the art that, under the situation that does not deviate from the spirit and scope of the present utility model that limited by appended claims, can make a variety of changes it in the form and details.
