The utility model content
The permanent magnet direct-driving aerogenerator that the purpose of this utility model provides the preceding supporting disk of a kind of rotor and uses this preceding supporting disk; make the fit structure of its integrated brake structure and safe locking mechanism; thereby reduce the requirement of generator volume inside; and operations such as the installation of being more convenient for, locking, shutdown, maintenance, thereby overcome the deficiencies in the prior art.
In order to solve the problems of the technologies described above, supporting disk before a kind of rotor of the utility model, the locked rotor plate that comprises supporting bracket and be fixed on the supporting bracket inboard, wherein, described locked rotor plate is annular, and annular inner portion is that brake disc, outer ring portion are provided with a plurality of locked rotor hole.
As further improvement of the utility model, described locked rotor is provided with lining in the hole.
Described locked rotor plate and supporting bracket are the foundry goods integral structure.
Described locked rotor plate and supporting bracket are split-type structural, and by welding or being spirally connected fixing.
In addition, the utility model also provides a kind of permanent magnet direct-driving aerogenerator, comprise behind rotor, stator, stator support, brake, rotor lock, the rotor supporting disk before supporting disk and the above-mentioned rotor, wherein: the brake disc of supporting disk cooperates with described brake before the described rotor, and the axial location in locked rotor hole is corresponding with the rotor lock.
After adopting above design, the utility model has following beneficial effect compared with the prior art:
1, supporting disk before the rotor of the present utility model, can guarantee the supporting role to external rotor, be convenient to again the unit shutdown operation that brakes, safety locking in the time of can also overhauling the wind-powered electricity generation unit, and the fore bearing pressing plate separated with supporting bracket, reduce the installation difficulty of forward spindle, effectively increased the braking radius, reduced the usage quantity of brake accordingly;
2, the utility model also can be before rotor arranges lining in the locked rotor hole of supporting disk, reduces the wearing and tearing of lock hole, increases the life-span of supporting disk before the rotor, safeguards more conveniently, operates simplyr, and practicality is stronger.
