Referring to FIG. 2, threaded rod 5 waits for that connector 6 and second waits for that connector, both ends correspond to first company of waiting for for connecting first
Fitting 6 and second waits for that connector is respectively arranged with thread segment.First waits for being provided with installation duct 10 in connector 6, installs duct
10 are fixedly connected with swivel nut 9, and 9 inner wall of swivel nut is provided with internal thread.Threaded rod 5 is arranged in installation duct 10, and one end passes through screw thread
Section waits for that connector 6 is threadedly coupled with first, and the other end stretches out installation duct 10 and waits for that connector is connect with second.Threaded rod 5 and
One waits for that the end that connector 6 is threadedly coupled is known as threaded ends.Between 5 liang of thread segments of threaded rod with installation duct 10 in spiral shell
It covers 9 contactless, vacant state, referred to as cantilever segment is in relative to installation duct 10.
From figure 1 it appears that the threaded rod centering holding meanss include holder 8.Holder 8 should be set to cantilever
7 positions far from threaded ends of section.Holder 8 may be provided with multiple, also can only be arranged one.Holder 8 is circular ties
Structure, including endoporus and periphery.Inner hole sleeve is set to the cantilever segment 7 of threaded rod 5.Periphery is provided with and installs in duct 10 in swivel nut 9
The helicitic texture of screw-thread fit.The helicitic texture of periphery realizes the support to cantilever segment 7 with 9 screw-internal thread fit of swivel nut, ensures spiral shell
Rasp bar 5 will not be deviateed installation centerline hole and be avoided to improve the accuracy of alignment of threaded rod 5 due to its own gravity or external force
It is inconvenient to be assembled caused by being misaligned due to threaded rod 5, and threaded rod 5 is broken, and waits for the generation for the problems such as connector damages.And
Threaded rod centering holding meanss are simple in structure, of low cost, easy to use.
Holder 8 is separate structure, including can be spliced into circular first splice 1 and second on endoporus circumferencial direction
Splice 2.Between first splice 1 and the connection end of the second splice 2, a side is provided with the grafting extended towards another party
Protrusion 4, another party are provided with the grafting groove 3 with 4 cooperation of grafting protrusion.When installation, grafting protrusion 4 is arranged in grafting groove 3,
And it is connected by the binder between two connection end of setting.By mating, it is ensured that the splicing precision of splice.It is logical
It crosses adhesive and realizes that splice is reliably assemblied on threaded rod 5.The end of grafting protrusion 4 and the bottom of grafting groove 3 have
The gap of setpoint distance, with accommodating enough adhesives.
It should be evident that the number of splice does not limit to two, can according to the outer diameter of cantilever segment 7 in threaded rod 5 or
The practical application scenes such as the structure and material of splice determine the number of splice.
As another embodiment, connected by buckle structure between contiguous concatenation part, such as barb structure.
As another embodiment, the first splice 1 only can connect realization by binder with the second splicing construction and spell
Fitting is reliably assemblied on threaded rod 5, can also be limited by installing the structure in duct 10, splice is reliably resisted against spiral shell
Rasp bar 5.
As another embodiment, the periphery of threaded rod centering holding meanss is provided on endoporus axis direction
At least three are resisted against installation 10 inner wall support protrusion of duct, and the branch to holder 8 and threaded rod 5 is completed by support protrusion
Support.
As another embodiment, when installation duct 10 is without swivel nut 9, periphery and the inner wall of the hole installing of holder 8 coordinate
Contact, to realize the support to threaded rod 5.Further, when 10 inner wall of installation duct of respective cantilevered section 7 is provided with internal thread,
The periphery of holder 8 is provided with the helicitic texture with corresponding screw-internal thread fit.
Using threaded rod as object factory this application technical solution in embodiment provided herein, but technical scheme
In connecting rod do not limit to threaded rod.Can be the connection rod structure of other forms, the connection rod structure of this type has and the
One waits for the first connecting pin of connector connection and the cantilever segment hanging relative to installation duct, equally faces and deviates in mounting hole
The problem of heart line, can carry out centering holding by connecting rod centering holding meanss.
There is provided a kind of embodiment of wind power generating set, including blade connecting screw, blade connecting screw one simultaneously herein
End screws in swivel nut 9 in blade, and the other end screws after passing through the connecting holes of pitch variable bearings with nut, to realize blade with
The connection of pitch variable bearings.It is provided with connecting rod centering holding meanss between the cantilever segment 7 and swivel nut 9 of blade connection bolt.This reality
It applies in example, blade connecting screw, that is, connecting rod.
When assembly, blade connecting screw is screwed first on the swivel nut 9 being embedded in blade body, in blade connecting screw
Expose and buckle holder 8 at the threaded hole on blade, and holder 8 is filled in the hole of swivel nut 9, to which support blade connects spiral shell
Bar, to ensure its centering.Then it is screwed with nut in the blade connecting screw other end.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
Among the protection domain that variation is created still in the utility model.
