Abstract
The utility model discloses a vertical spindle wind motor, comprising a wind wheel, a main spindle and a generator, wherein a bearing is arranged between the wind wheel and the main spindle, a bearing inner race is fixedly connected with the main spindle, the bearing outer race is fixedly connected with the wind wheel, and the wind wheel is also fixedly connected with the rotor of the generator. When the wind motor rotates, the wind wheel rotates to drive the rotor of the generator to rotate, or the wind wheel drives a transmission mechanism which then drives the rotor of the generator to rotate, consequently, the bearing outer race is rotated together with the wind wheel, and both the inner race and the main spindle do not rotate. By adopting the structure, the main spindle almost does not bear torque but bear the bending moment, and the bearing almost dose not bear bending moment but bear the radial force brought by the wind load and the axial force brought by the gravity of the wind wheel.
Description
Technical field
The utility model relates to a kind of wind motor, particularly a kind of Da Lie lift vertical shaft wind motor.
Background technique
Traditional vertical-shaft wind motor comprises parts such as wind wheel, main shaft, base, driving mechanism, generator, and wind wheel is connected with main shaft, and main shaft passes base and is connected with driving mechanism, between main shaft and the base pivot joint is arranged.In this structure, main shaft and wind wheel together rotate, main shaft should bear moment of flexure, bear moment of torsion again, load is unfavorable to main shaft, and the pin-joint mechanism between main shaft and the base is owing to bearing the moment of flexure that wind wheel and main shaft bring, so load is very big, and, cause stressed very big because the arm of force of pin-joint mechanism is very short.This makes that main shaft load is big, size is big, cost is high, and pin-joint mechanism (being generally bearing) size is big, cost is high, reliability is low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of vertical-shaft wind motor, comprise wind wheel, main shaft and generator, be provided with bearing between wherein said wind wheel and the main shaft, wherein bearing inner race is fixedlyed connected with main shaft, bearing outer ring is fixedlyed connected with wind wheel, and wind wheel is also fixedlyed connected with the rotor of generator.
The further technical characterstic of the utility model is that described wind wheel also comprises sleeve, and the outer ring of wherein said sleeve and described bearing and the rotor of generator are fixedlyed connected.
Be provided with driving mechanism between described wind wheel and the generator, wherein the input end of wind wheel and driving mechanism is fixedlyed connected, and the output terminal of driving mechanism is fixedlyed connected with the rotor of generator.
Described wind wheel also comprises sleeve, and the outer ring of wherein said sleeve and described bearing and the input end of driving mechanism are fixedlyed connected.
Described bearing is a selfaligning bearing.
Described main shaft is divided into two sections at least, adopts dismantled and assembled fixedly connected between every section.
The beneficial effects of the utility model are:
Owing to be provided with bearing between wind wheel and the main shaft in the utility model, wherein bearing inner race is fixedlyed connected with main shaft, bearing outer ring is fixedlyed connected with wind wheel, wind wheel is also fixedlyed connected with the rotor of generator, and when wind motor turned round, wind wheel rotated and drives generator amature and rotates, perhaps wind wheel drives driving mechanism, drive generator amature by driving mechanism and rotate, the outer ring of bearing and wind wheel together rotate like this, and inner ring and main shaft do not rotate.Under this structure, main shaft bears moment of torsion hardly, only bears moment of flexure, and bearing bears moment of flexure hardly, only bears the axial force that the radial force that brought by wind and wind wheel gravity bring.This makes the load of main shaft and bearing significantly reduce, and material requested requires to reduce, and has not only saved cost, and also significantly improve working life.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the utility model first embodiment's a structure sectional view, this vertical-shaft wind motor is a direct-driving type, it comprises wind wheel 1, main shaft 2 and generator 3, be provided with bearing 4 between wherein said wind wheel 1 and the main shaft 2, its middle (center) bearing 4 inner rings are fixedlyed connected with main shaft 2, fixedly connected with wind wheel 1 in bearing 4 outer rings, wind wheel 1 is also fixedlyed connected with the rotor of generator 3.In the present embodiment, described main shaft 2 adopts segmentation structure, is connected by flange between every section.Can make main shaft 2 be convenient to install like this.According to the installation needs of actual blower fan, main shaft 2 is divided into two sections, three sections, four sections even more, also can adopt other dismantled and assembled fixedly connected mode between every section.
Fig. 2 is the utility model second embodiment's a structure sectional view, and it and embodiment's 1 difference is that wind wheel described in the present embodiment 1 also comprises sleeve 101, and the outer ring of wherein said sleeve 101 and described bearing 4 and the rotor of generator 3 are fixedlyed connected.Owing to introduced sleeve 101, it can improve the rigidity of wind wheel 1, guarantees the angular phasing unanimity that rotate the wind wheel upper and lower, can not carry to produce under the effect at wind and reverse relatively.
Fig. 3 is the utility model the 3rd embodiment's a structure sectional view, vertical-shaft wind motor shown in the present embodiment, wherein be provided with driving mechanism 5 between wind wheel 1 and the generator 3, wherein wind wheel 1 is fixedlyed connected with the input end of driving mechanism 5, the output terminal of driving mechanism 5 is fixedlyed connected with the rotor of generator 3, owing to add driving mechanism 5 in the present embodiment, driving mechanism can be a coupling, gear-box, their combination or other driving mechanisms, when driving mechanism is coupling, described vertical-shaft wind motor of the present utility model is the direct-driving type wind motor, vertical-shaft wind motor shown in the present embodiment is the direct-driving type wind motor, and what its driving mechanism 5 adopted is coupling.When driving mechanism is the combination of gear-box or gear-box and coupling, described vertical-shaft wind motor of the present utility model is a non-direct drive type wind motor, embodiment as shown in Figure 4, for alleviating torque ripple, between gear-box and the generator damping device 6 can be set, as flexible coupling, it is more steady that meeting is transmitted in the rotation between gear-box and the generator like this.And because the driving mechanism 5 in the present embodiment adopts gear-boxes, rotation can also be delivered to outside the main shaft 2, generator 3 and main shaft 2 mutual noninterferences like this, thus made things convenient for the layout of generator.And, therefore can realize the mode of multi-stage diffluence because the driving mechanism 5 of the vertical-shaft wind motor described in the present embodiment adopts gear-box.Gear-box in the present embodiment is an one-level, can also adopt secondary or tertiary gear case to carry out transmission.Main shaft 2 is divided into three sections in the present embodiment, adopts dismantled and assembled fixedly connected mode between every section.Certainly, the tube-in-tube structure among the embodiment two can be suitable in the foregoing description equally.
