Find through retrieval prior art, Chinese patent application number is 200710010445.8, publication number is the application for a patent for invention of CN101016881, put down in writing a kind of " megawatt semi-direct driving type wind driven generator group ", this technology comprises: wind wheel, variable pitch device, main shaft, speedup box, coupling, generator, chassis, cabin, yaw motor and control system, on the chassis, cabin, be fixed with yaw motor, generator, the sidewall on speedup box and chassis, cabin is fixed, speedup box is the planetary step-up gear of one-level, and motor is the low-speed permanent-magnet three-phase synchronous generator.But this technology comprises the main shaft rigidity that produced by main shaft and main shaft to neutral and axial play problem, and the length of unit horizontal axis also can increase.This technology is because of its gear-box is fixed in the sidewall on chassis, cabin simultaneously, just requires the sidewall in cabin and chassis need do special reinforcement and handles, and the both wings stress surface is also less relatively, and stress is more concentrated, and install, extremely difficult aligning fixedly the time; The cabin lengthening that main shaft structure caused has improved the requirement that equipment aligns the medial axis, and main shaft place torsion is bigger, and is aging easily damaged.
The model utility content
The purpose of this utility model is the defective at above-mentioned prior art, a kind of non-principal shaft half directly-drive wind generator device is provided, solve the rigidity of main shaft in the prior art and, when shortening cabin length, alleviating complete machine weight, reduced the manufacture cost of generator by no main shaft structure neutral and axial play problem; Fix by flange arrangement and also effectively to have eliminated stress and concentrate, structure is more convenient simultaneously, easily installs.
The utility model is achieved through the following technical solutions, the utility model comprises: gear-box, magneto alternator, impeller, cabin, deck store and pylon, wherein: impeller is connected with the gear-box input end that is arranged at the front portion, cabin, magneto alternator is arranged at the middle part, cabin, the input end of magneto alternator links to each other with the output terminal of gear-box, deck store is arranged at nacelle rear, the pylon that the bottom, cabin is provided for supporting.
Described gear-box is the one-level step-up gear.
Described impeller tip is provided with gear-box forward flange set on wheelboss flange and the gear-box input end setting that matches, and this gear-box forward flange is provided with the guiding seam.
The gear-box rear flange that described gear-box output terminal the is provided with setting that matches with the cabin forward flange that the front portion, cabin is provided with, this gear-box rear flange is provided with the guiding seam.
Described guiding seam is the inclined-plane, obtuse angle with angle theta, and the span of this angle theta is 130 ° to 160 °.
Adopt the flange arrangement that the guiding seam is arranged between the assembly of the present utility model, its compact structure is easy to processing, technically can guarantee more that also it is to rigidity and to requirement of neutral.And install and fix conveniently, more suitability for scale production.By no main shaft and coupler structure, fundamentally solved in the present technology to the rigidity of main shaft and to the requirement of neutral and axial float.The length of unit horizontal axis is reduced greatly, has saved the space, has alleviated complete machine weight.Simultaneously, the gear-box front end and back end is connected with the flange-type that the interface in wheel hub and cabin is seam, and it is big, stressed more even to be fixed on the sidewall of cabin stress surface than gear-box, and it is concentrated effectively to eliminate stress.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment comprises: impeller 1, gear-box 2, magneto alternator 3, cabin 4, deck store 5 and pylon 6; Be provided with wheelboss flange 7 at impeller 1 end, input end and output terminal at gear-box 2 are respectively equipped with gear-box forward flange 8 and gear-box rear flange 9,4 front portion is provided with cabin forward flange 10 in the cabin, wherein: impeller 1 is connected with the gear-box forward flange 8 of gear-box 2 by wheelboss flange 7, gear-box rear flange 9 is fixedlyed connected with cabin forward flange 10, magneto alternator 3 is arranged at 4 middle parts, cabin, the input end of magneto alternator 3 links to each other with the output terminal of gear-box 2, deck store 5 is arranged at 4 rear portions, cabin, the pylon 6 that 4 bottoms, cabin are provided for supporting.
Described impeller 1 is three blade impellers, and its working speed is 10 rev/mins to 20 rev/mins;
