Description
Technical field
The utility model belongs to wind power generating set, relates in particular to a kind of wind driven generation set main shaft and wheel hub assembly structure.
Background technique
Wind-power electricity generation is because its special advantages has obtained development faster at home and abroad, and the design and the manufacture level of related industry also are improved simultaneously.Also ripe gradually with the hoisting technology that the continuous increase of wind-driven generator pool-size adapts, but main shaft and wheel hub assembling difficulty in hoisting process is bigger, shows that mainly the attachment hole of main shaft and wheel hub is difficult to realize to neutrality.
At present; When carrying out the wind power generating set lifting, the centering that the existing structure design can realize main shaft and the rotatable central shaft of wheel hub, but there is certain problem in the centering of main shaft and wheel hub attachment hole; Severe patient even cause indivedual bolts to assemble influences the wind power generating set Security.
Present structural design can only guarantee the centering of main shaft and wheel hub rotary middle spindle, but can't accurately realize the attachment hole centering of main shaft and wheel hub.
Summary of the invention
Can not realize good centering, the slower deficiency of assembling speed in the main shaft that overcomes existing wind power generating set and the wheel hub assembly structure, the utility model provides a kind of good centering, Rapid Realization of realizing to lift the main shaft and the wheel hub assembly structure of the wind power generating set of centering.
The utility model solves the technological scheme that its technical problem adopted:
A kind of main shaft of wind power generating set and wheel hub assembly structure comprise main shaft, wheel hub and bolt, and the outer ring of the attachment face of said main shaft is furnished with unthreaded hole; The outer ring of the attachment face of said wheel hub is furnished with tapped hole, and said bolt is installed in said unthreaded hole and the tapped hole, and said assembly structure also comprises alignment pin; Said alignment pin comprises guide section, thread section, polished rod section and end cap, and said guide section is tapered, and said guide section and said thread section join; Said thread section and polished rod section are joined; Said polished rod section and end cap join, and the size of said thread section and the size of said tapped hole match, and the size of said polished rod section and the size of said unthreaded hole match.
Further, said end cap is a hexagon head.The form that certainly, also can adopt other to be convenient to assemble.
Further again, the cone angle of said guide section is 15 °～45 °.In principle, cone angle is more little, helps realizing leading role more, still, because the installing space of main shaft and wheel hub is limited, also can adopt bigger cone angle, and for example 60 ° etc., big cone angle also has certain leading role.
The technical conceive of the utility model is: wheel hub and the lifting of main shaft guiding are mainly accomplished by alignment pin.Alignment pin can be divided into guide section, thread section, polished rod section and hexagon head four parts, and the thread section diameter is less than polished rod section diameter.
Simultaneously; Alignment pin thread section and polished rod section size should match with main shaft and wheel hub corresponding size respectively; Rule of thumb, alignment pin polished rod section cooperates with the main shaft attachment hole and should elect
as
The beneficial effect of the utility model mainly shows: can realize good centering, Rapid Realization lifting centering.
Description of drawings
Fig. 1 is the main shaft of wind power generating set and the assembling schematic representation of wheel hub;
Fig. 2 is the structural representation of alignment pin;
Fig. 3 is the structural representation of main shaft;
Fig. 4 is the structural representation of wheel hub.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 4, a kind of main shaft of wind power generating set and wheel hub assembly structure comprise main shaft 1, wheel hub 2 and bolt; The outer ring of the attachment face of said main shaft 1 is furnished with tapped hole, and the outer ring of the attachment face of said wheel hub 2 is furnished with unthreaded hole, and said bolt is installed in said unthreaded hole and the tapped hole; Said assembly structure also comprises alignment pin 3; Said alignment pin 3 comprises guide section, thread section, polished rod section and end cap, and said guide section is tapered, and said guide section and said thread section join; Said thread section and polished rod section are joined; Said polished rod section and end cap join, and the size of said thread section and the size of said tapped hole match, and the size of said polished rod section and the size of said unthreaded hole match.
Said end cap is a hexagon head.The form that certainly, also can adopt other to be convenient to assemble.
The cone angle of said guide section is 15 °～45 °.In principle, cone angle is more little, helps realizing leading role more, still, because the installing space of main shaft and wheel hub is limited, also can adopt bigger cone angle, and for example 60 ° etc., big cone angle also has certain leading role.
The working procedure of present embodiment is: after the assembling of accomplishing cabin and pylon; At first an alignment pin is put into the attachment hole that main shaft is connected with wheel hub; When lifting wind wheel apart from the suitable distance of main shaft by ground; The staff who in the cabin, observes utilizes walkie-talkie and crane operation personnel to get in touch, and the fine setting that lifts guarantees that as far as possible the main shaft attachment face is parallel with the wheel hub attachment face.After main shaft attachment face and wheel hub attachment face safety are fitted, be screwed into the alignment pin thread section in the hub stud holes earlier, insert all the other connecting bolts more successively and tighten, unload alignment pin at last, insert last bolt again and accomplish and assemble.Because alignment pin has the guide section of circular cone type and the positioning section of column type, so can be implemented in the automatic centering of main shaft and wheel hub connecting bolt hole in the hoisting process.After realizing centering, the staff can realize the smooth assembling of main shaft and wheel hub connecting bolt successively.
After accomplishing the assembling of main shaft and wheel hub, lifting was used after the alignment pin that unloads gave over to.
In the present embodiment, main shaft and wheel hub need not special processing; Alignment pin can use repeatedly; Need not special operation tool; Can Rapid Realization lifting centering.
