1) due on the assembly after pre-connection, rotating disk is stretched out in one end of bolt, therefore, when wind field in-site installation wind wheel, probably the thread damage of the bolt installed fallen or bolt hit curved, and once occur that these situations will change bolt, and be very troublesome at wind field spot replace bolt, greatly affect installation efficiency;
2) in addition, because nut is embedded in rotating disk in advance, therefore, once after installing wind wheel, this nut just can not be changed, and damages, just cannot take off from joint if there is bolt fracture or other, like this, rotor, main bearing, degree of being connected firmly between rotating disk and wind wheel can greatly be reduced.
Model utility content
Technical problem to be solved in the utility model is, a kind of bolt failure phenomenon avoiding pre-connection bolt to stretch out rotating disk bringing is provided, thus greatly improve installation efficiency, and the connection set of wind wheel in the wind-driven generator that can change in the later stage of this pre-connection bolt.
For solving the problems of the technologies described above, the connection set of wind wheel in the wind-driven generator that the utility model provides, comprise the rotor, main bearing, rotating disk and the wind wheel that are linked together by fastening piece, described main bearing close-fitting is on the main shaft of generator, rotor is positioned at the inner side of main bearing, rotating disk is socketed in outside main bearing, and wind wheel is positioned at the outside of main bearing; Described fastening piece comprises the first bolt and the second bolt, rotor, main bearing and rotating disk are bolted together by first, and one end of the first bolt is positioned at rotating disk, wind wheel and rotating disk are bolted together by second, and one end of the second bolt is also positioned at rotating disk.
This connection set also comprises coupling sleeve, rotating disk is provided with holding cavity near one end of wind wheel, described coupling sleeve is positioned at holding cavity, and the threaded one end of the first bolt is connected to one end of coupling sleeve, and one end of the second bolt is also threaded in the other end of coupling sleeve.
The end face of described coupling sleeve is lower than the end face of rotating disk, and coupling sleeve has the symmetrical plane for clamping on one end outer circle wall of wind wheel.
The outer circle wall of described coupling sleeve near one end of wind wheel is outer-hexagonal shape.
Described coupling sleeve is cylindrical near one end of rotor, and the gap between the coupling sleeve external diameter of this cylindrical part and rotating disk is less than 0.5mm.
After adopting above structure, the utility model compared with prior art, has the following advantages:
1) owing to first rotor, main bearing and rotating disk first being got up by the first bolt and coupling sleeve pre-connection, and coupling sleeve is positioned at rotating disk inside, first bolt can't stretch out beyond rotating disk end face, therefore, when wind field in-site installation wind wheel, avoid occurring the thread damage of the bolt installed to fall or bolt being hit curved phenomenon, thus also do not need to change bolt, greatly improve installation efficiency;
2) simultaneously, be connected with a coupling sleeve due to a bolt of the prior art is divided into two bolts, in other words, the connection of wind wheel and the connection of rotor are separate, even if need after the first bolt failure to change, also can take off at any time and screw off the first bolt from coupling sleeve, not need to pull down wind wheel, therefore, bolt is changed very convenient;
3) exterior edge face of coupling sleeve is lower than rotating disk end face, is in order to rotating disk end face can better contact with wind wheel end face, and does not occur that the phenomenon of wind wheel installation interfered by coupling sleeve;
4) be cylinder by coupling sleeve near rotor one end, outer circle wall near wind wheel one end is designed to symmetrical plane, or even outer-hexagonal shape, this is to apply rated moment to grip to these planes by hydraulic spanner when the connection of coupling sleeve and the first bolt, thus makes easier for installation; In addition, the gap between the cylindrical end of coupling sleeve and rotating disk mostly is 0.5mm most, locates with this.
