Embodiment
The generalized section of the driving chain of wind generating set that Fig. 1 provides for the utility model embodiment.This driving chain of wind generating set comprises wheel hub 1, main shaft 2, main bearing, bearing mounting base 4, mainframe 5, gear-box 8 and generator 10, and generator 10 is arranged on the generator support 11; Main bearing comprises front main bearing 6 and rear min bearing 7, and the Internal and external cycle of main bearing is connected with bearing mounting base with main shaft 2 respectively and is connected; Bearing mounting base 4 is installed on the mainframe 5, and the front end flange of main shaft 2 is connected with wheel hub 1, and rear end flange is connected with the low speed end of gear-box 8, and the speed end of gear-box 8 is connected with generator 10 by coupling 9.
Main bearing has two, is divided into front main bearing 6 and rear min bearing 7.Use a main bearing to compare with one-point type supporting, the two point form supporting can effectively reduce bearing diameter, such complete machine width and highly also can thereupon diminishing, and the while has also been improved bearing life and reliability.
Bearing mounting base 4 cooperates with the outer ring of two main bearings, and two mounting holes of this kind structure can be processed at same lathe, more easily guarantees the coaxality after two bearings are installed, and is beneficial to assembling, and shaft strength is also better.
Aforesaid driving chain of wind generating set, front main bearing 6 are the double-row conical bearing that four-point contact ball or face-to-face mode are installed; Rear min bearing 7 is roller bearing.Front main bearing 6 adopts such setting type to have preferably rigidity, can bear very large axial force and radial load simultaneously.Rear main bearing 7 adopts roller bearing, very large radial force can be delivered on the bearing mounting base 4, simultaneously because the roller bearing Internal and external cycle allows certain moving axially, so whole assembling is convenient in the configuration of this main bearing.Front main bearing 6 suffered load are more complicated also larger as can be known by force analysis in addition, so front main bearing 6 is stressed also more reasonable near the arrangement of mainframe 5.
Aforesaid driving chain of wind generating set also comprises: bearing (ball) cover.Bearing (ball) cover is divided into anterior bearing (ball) cover 13 and rear bearings end cap 12.Bearing (ball) cover can guarantee the sealing of bearing.
Aforesaid driving chain of wind generating set also comprises: impeller locking plate 3 is provided with circular hole on the impeller locking plate 3;
Accordingly, also be provided with corresponding room on the mainframe 5, by the impeller locking dead mainframe 5 of lock and main shaft 2, to make things convenient for unit maintenance.
In sum, the driving chain of wind generating set that the utility model provides by rational Transmitted chains design, effectively reduces unit component sizes and force-bearing situation, and then has reduced the difficulty of unit weight and transportation and lifting.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment's technological scheme of the utility model.
