Description
Technical field
This utility model relates to wind turbine equipment field, is specifically related to the new blade changeover mechanism of a kind of wind-driven generator.
Background technology
Along with blower fan is in the extensive application of national economy every field, the performance of blower fan itself is had higher requirement.Impeller is the core component of whole blower fan, and blade is blower fan realizes the core component of gas transmission, and the quality of whole fan performance, as the important component part of impeller, is played vital effect by blade.
The continuing to increase of single-machine capacity along with wind-driven generator, the length of blade is also being continuously increased, and when the power of wind-driven generator changes, blade dimensions also can change therewith, but while changing blade, the pitch variable bearings being connected with this and wheel hub also to be changed.Now will redesign wheel hub, bearing size, otherwise blade will be unable to be installed on wheel hub.But, new wheel hub, bearing redesign the processes such as structure design to be experienced, intensity analysis, optimization design, the longest, costly.And between pitch variable bearings inner ring and blade, install a changeover portion additional so that during generator power change, either increase or reduce, it is only necessary to changing blade the most permissible, without changing pitch variable bearings and wheel hub, both having decreased cost, and added again ageing.
Utility model content
Subject matter to be solved in the utility model, it is simply that can only be for the blade of specific dimensions for existing same bearing, while changing blade, pitch variable bearings and wheel hub also have to do corresponding replacing.This utility model makes same bearing can correspond to the blade of different-diameter, it is simple to dismounting impeller, time saving and energy saving, it is to avoid fan part is caused damage.
This utility model is achieved through the following technical solutions: the new blade changeover mechanism of a kind of wind-driven generator, it includes changeover portion, the upper end of changeover portion is connected with blade, lower end is connected with pitch variable bearings inner ring, pitch variable bearings outer ring is directly connected with the wheel hub of wind-driven generator, and above-mentioned pitch variable bearings inner ring and outer ring are for the central axis of pitch variable bearings, and the power suffered by blade is directly delivered to changeover portion, and then it has been delivered to wheel hub by pitch variable bearings, it is eventually transferred to generating set.
Described changeover portion is used for connecting pitch variable bearings inner ring and blade, changeover portion is offered the hole corresponding to different impeller diameters so that same bearing can correspond to various sizes of impeller.
The hole offered on above-mentioned changeover portion, the form in hole can be circular hole or strip hole so that more convenient.
The upper end of described changeover portion and blade are connected by the 3rd connecting bolt, and the lower end of described changeover portion and pitch variable bearings inner ring are connected by the second connecting bolt, add packing ring with nut and apply pretightning force below pitch variable bearings inner ring.Wheel hub uses the first connecting bolt to be connected with pitch variable bearings outer ring, and top nut adds packing ring and is connected with bolt.
The inner ring of above-mentioned bearing uses the most concordant design with cycle surface, and the end face of inner ring and outer ring is the most at intervals, and the setting of this distance makes shaft strength more uniform, rotates more flexible.

Figure number indicates: 1 wheel hub, 2 first connecting bolts, 3 pitch variable bearings outer rings, 4 pitch variable bearings inner rings, 5 changeover portions, 6 second connecting bolts, 7 the 3rd connecting bolts, 8 blades, 9 first packing rings, 10 first nuts, 11 second nuts, 12 second packing rings.
Detailed description of the invention:
For being more fully understood that this utility model, below in conjunction with the accompanying drawing in this utility model example, the technical scheme in this utility model embodiment is specifically described.
As shown in Figure 1, a kind of new blade changeover mechanism of wind-driven generator, including changeover portion 5, the upper end of changeover portion 5 is connected with blade 8, and lower end is connected with pitch variable bearings inner ring 4, and pitch variable bearings outer ring 3 is directly connected with the wheel hub 1 of wind-driven generator, above-mentioned pitch variable bearings inner ring 4 and outer ring 3 are for the axis of pitch variable bearings, power suffered by blade 8 is directly delivered to changeover portion, and then has been delivered to wheel hub by pitch variable bearings, is eventually transferred to generating set.
Described changeover portion 5 is used for connecting pitch variable bearings inner ring 4 and blade 8, changeover portion 5 is offered the hole corresponding to different impeller diameters so that same bearing can correspond to various sizes of impeller.
In this utility model, upper end and the blade 8 of changeover portion 5 are connected by the 3rd connecting bolt 7, and lower end and the pitch variable bearings inner ring 4 of changeover portion 5 are connected by the second connecting bolt 6.
As shown in Figure 2, the detail display opening approach of changeover portion, what scheme one was offered is strip hole, simple and convenient easy processing, scheme two can offer corresponding circular hole according to the diameter of different leaves on changeover portion, the circular hole of same diameter requires with one heart, to realize the blade of same pitch variable bearings correspondence different model with this, and scheme one is more easy to processing relative to scheme two.
As it is shown on figure 3, the rotation having rotarily driven changeover portion 5 of blade 8, and then it is delivered to the inner ring 4 of pitch variable bearings, it is achieved that the synchronous rotary between pitch variable bearings inner ring 4 and blade 8.And pitch variable bearings outer ring 3 is fixed on wheel hub 1.From the point of view of motion mode, transmission blade and wheel hub between can be fully achieved.
As shown in Figure 4, add packing ring 12 with nut 11 below pitch variable bearings inner ring 4 and apply pretightning force.Wheel hub 1 uses the first connecting bolt 2 to be connected with pitch variable bearings outer ring 3, and top nut 10 adds packing ring 9 and is connected with bolt 2.
The end face of pitch variable bearings is not concordant, and pitch variable bearings Internal and external cycle is the most with bolts, and pitch variable bearings outer ring 3 is connected with wheel hub 1, and the upper end of the first nut 10 is slightly below the upper surface of bearing inner race 4；Pitch variable bearings inner ring 4 top is connected with changeover portion, and the lower surface of bearing outer ring 3 will be less than the lower surface of the second nut 11, and such design makes wheel rotation more flexible, easy for installation.
Embodiments described above is a part of embodiment the most of the present utility model; based on the embodiment in this utility model; the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, belongs to protection domain of the present utility model.
