Description
Technical field
The utility model relates to the technical fields of wind power generating set electric slip ring, refer in particular to a kind of for improving wind-force hair
The device of motor group electric slip ring bearing life.
Background technique
Known in the industry, electric slip ring plays the role of transmission power in wind power generating set and connects with signal rotation, carries on a shoulder pole
The power of whole system is born, control signal and data transfer function is component very crucial in entire blower fan system, and electricity is sliding
The service life of ring also will generate tremendous influence to the availability of wind power generating set.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, propose a kind of for improving wind power generating set
The device of electric slip ring bearing life reduces the generation frequency of electric slip ring lifetime inner bearing failure, reduces wind power generating set
Failure rate, to improve the availability and generated energy of wind power generating set.
To achieve the above object, technical solution provided by the utility model are as follows: one kind is for improving wind power generating set
The device of electric slip ring bearing life, the electric slip ring are mounted on the gear-box hollow shaft tail of wind power generating set using cantilevered fashion
Portion, the electric slip ring point have first half and latter half, and first half is the rotation being connected with gear-box hollow shaft tail portion
Part, latter half are fixed part, and rotating part and fixed part are attached by bearing, electric slip ring latter half
Weight and the weight of electric slip ring cable are born by bearing completely；Described device includes adjustable elastic support base and slip ring
Support frame, wherein the adjustable elastic support base is fixedly mounted on the engineroom flat of wind power generating set, the slip ring branch
Support is fixedly mounted on adjustable elastic support base the electric slip ring latter half for supporting and being positioned above, and makes electric slip ring by original
Carry out the fixed cantilever position in one end and change into both ends to fix, and then makes that bearing is not subjected to electric slip ring latter half and cable is made
At moment of flexure and improve its service life.
The top surface that the slip ring support frame is in contact with electric slip ring latter half is and electric slip ring latter half outer peripheral surface phase
Matched arc surface enables the top surface of slip ring support frame and electric slip ring latter half by adjusting adjustable elastic support base
Outer peripheral surface be in contact.
The utility model compared with prior art, have the following advantages that with the utility model has the advantages that
1, the service life of unit electric slip ring bearing can be greatly improved.
2, the failure rate of unit electric slip ring is reduced, unit availability is improved.
3, install convenient, using reliable.
Detailed description of the invention
Fig. 1 is the wind power generating set electric slip ring mounting means of the prior art.
Fig. 2 is that utility model device uses schematic diagram on electric slip ring.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
As shown in Figure 1, the electric slip ring of doubly fed wind turbine generator is mounted on gear-box hollow shaft 3 using cantilevered fashion
Tail portion, the first half 11 of electric slip ring belong to the rotating part of electric slip ring, and latter half 12 belongs to fixed part, first half 11
It is attached with latter half 12 by bearing 2.Wind power generating set at work, the weight of electric slip ring latter half 12 and
The weight of electric slip ring cable 4 is born by bearing 2 completely, and in unit running process, bearing 2 will bear biggish moment of flexure, when long
Between run after can be easy to cause bearing 2 damage, and when unit occur biggish vibration when, due to electric slip ring latter half cantilever
It is easy to appear substantially vibrations, and wind power generating set to be caused to quote wheel speed hypervelocity failure for structure.
In order to change this cantilever working condition of wind power generating set electric slip ring, as shown in Fig. 2, at the rear portion of electric slip ring
Increase a structure, specially for improving the device of wind power generating set electric slip ring bearing life provided by the present embodiment,
Described device includes adjustable elastic support base 51 and slip ring support frame 52, wherein the adjustable elastic support base 51 is solid
On the engineroom flat 6 of wind power generating set, the slip ring support frame 52 is fixedly mounted on adjustable elastic support base for Dingan County
The electric slip ring latter half 12 being positioned above is supported on 51, changes into electric slip ring by the cantilever position that original one end is fixed
Both ends are fixed, and then bearing 2 is made to be not subjected to moment of flexure caused by electric slip ring latter half 12 and cable 4, are also reduced simultaneously
The large magnitude that electric slip ring tail portion generates when unit vibration extends the service life of unit electric slip ring and reduces unit and quotes impeller
The possibility for the failure that exceeds the speed limit.
The top surface that the slip ring support frame 52 is in contact with electric slip ring latter half 12 be with outside electric slip ring latter half 12
The arc surface that circumferential surface matches, by adjusting the height of adjustable elastic support base 51, can make the top surface of slip ring support frame 52 with
The outer peripheral surface of electric slip ring latter half 12 is in contact, it is ensured that device installation is not subjected to electric slip ring latter half 12 with rear bearing 2
With moment of flexure caused by cable 4, with achieve the purpose that extend 2 service life of bearing.
Embodiment described above is only the preferred embodiment of the utility model, and the implementation of the utility model is not limited with this
Range, therefore all shapes according to the utility model, change made by principle, it should all cover within the protection scope of the present utility model.
