Abstract
The invention relates to an inner stator bracket for a direct-drive generator. The inner stator bracket comprises a cylindrical body, a main supporting plate and an auxiliary supporting plate, wherein the main supporting plate is arranged on the inside surface of the rear port of the cylindrical body; and the auxiliary supporting plate is arranged on the inside surface of the front port of the cylindrical body. The inner stator bracket is applied to supporting the inner stators of a double-stator permanent magnetic direct-drive wind-driven generator; and since the generator with a stator support structure is larger in rotor size, the inner stator bracket can be directly used for laminating iron cores of the inner stators. The inner stator bracket is applied to braking equipment of a mounting unit of the double-stator permanent magnetic direct-drive wind-driven generator and rotor locking equipment for halt overhaul of the mounting unit.

The purpose of this invention is to provide a kind of internal stator support for directly driving generator, make it can directly apply to repeatedly pressing of inner-stator iron core, be convenient to simultaneously install brake appts and locked rotor equipment; the convenient shutdown overhauled; make simply, easy for installation, thus overcome the deficiencies in the prior art.
For solving the problems of the technologies described above, a kind of internal stator support for directly driving generator of the present invention comprises cylindrical shell, main supporting plate and sub-strut plate, and wherein: main supporting plate is installed in the medial surface of cylinder back-end mouth, and the sub-strut plate is installed in the medial surface of barrel front end mouth.
As a further improvement on the present invention, described sub-strut plate rear side has the rotor lock mount pad along the cylinder inboard wall circle distribution.
Described sub-strut plate rear side has mounting seat of brake along the cylinder inboard wall circle distribution.
Be provided with reinforcement between described cylinder inboard wall and main supporting plate, the sub-strut plate.
Main supporting plate is circular, and is provided with a plurality of lightening holes along annulus.
Described cylinder back-end is provided with the seam for the axial installation site of restriction inner-stator iron core.
The outer peripheral face of described cylindrical shell is provided with for limiting in relative rotation keyway of inner-stator iron core and cylindrical shell.
After adopting above design, the present invention has following beneficial effect compared with the prior art:
1, the present invention is applied to the support of double-stator permanent magnet direct-driven wind power generator internal stator, because the rotor volume of the generator of stator support structure is larger, therefore can be directly used in repeatedly pressing of internal stator iron core;
2, the present invention has satisfied the installation requirements that double-stator permanent magnet direct-driven wind power generator is installed the brake appts of unit and is applied to install the locked rotor equipment of compressor emergency shutdown maintenance simultaneously.
