Abstract
The utility model relates to a generator, in particular to a wind driven generator. The wind driven generator comprises an upright post, a support, a first bearing, a second bearing, an input shaft, an output shaft, a generator and a fan blade; the support is fixed at one side surface of the top end of the upright post; the first bearing is arranged on the support; the fan blade is arranged at one end of the input shaft; the other end of the input shaft is arranged near the upright post coaxially with the output shaft; the second bearing is arranged on the output shaft near the upright post; the output shaft is connected with the generator; and the input shaft passes through the first bearing. The utility model improves the carrying capacity of the whole generating set and changes a cantilever mechanism into a simply support mechanism, therefore, the working conditions of the bearings are improved, and the lives of the bearings are prolonged.
Description
Technical field
The utility model relates to a kind of generator, relates in particular to a kind of wind-driven generator.
Background technique
Wind energy power and solar electrical energy generation are two emerging big clean energy resourcies of the world today, also are effective solution routes of current oily resource of reply and coal resource exhaustion.Have vast shore line, vast marsh and desert steppe in China, have abundant wind energy resources, utilize wind-force to generate electricity and have boundless prospect.
Current, in various types of horizontal axis wind-driven generators, all exist a problem that is difficult to overcome, the life-span that is bearing is shorter, compares with the usage requirement of blower fan, also exists certain distance, also therefore, the bearing that blower fan is used, its manufacture cost is very high, and it has occupied suitable ratio in the whole blower fan price.
Why cause the horizontal axis bearing to be difficult to satisfy usage requirement working life, its reason is exactly that bearing is in its working state, the non-constant of its stress, it has born the radial load that fan blade and other parts caused, and also needs to bear the effect of the very big moment of flexure that causes because of fan blade simultaneously.For this reason, the wearing and tearing of bearing are very serious.
The model utility content
The utility model provides a kind of wind-driven generator, by changing the stressing conditions of whole device, can improve the stressing conditions of existing generator at the running middle (center) bearing, prolongs the working life of bearing.
The utility model adopts following technological scheme:
A kind of wind-driven generator comprises column, support, clutch shaft bearing, second bearing, input shaft, output shaft, generator, fan blade; Support is fixed on a side on column top, arrange clutch shaft bearing on the support, an end of described input shaft is arranged fan blade, and the other end is arranged near the column place in the mode with the output shaft concentric shafts, and arrange second bearing at output shaft near the column place, output shaft is connected with generator; Input shaft passes clutch shaft bearing.
Wind-driven generator described in the utility model, described support in echelon, fixedlying connected with column in trapezoidal bottom surface, arranges convex key on the narrower end face, arranges clutch shaft bearing in convex key.
Wind-driven generator described in the utility model also comprises gear-box, is connected by gear-box between described input shaft and the output shaft.
Wind-driven generator described in the utility model, described gear-box are the Tooth wheel with changeable teeth casees.
Beneficial effect
This patent has improved the stressing conditions of whole generating device, makes it become freely-supported mechanism from cantilever mechanism, thereby has improved the working state of bearing, has prolonged the life-span of bearing.
This patent is simple in structure, has reduced the usage requirement of bearing, thereby has reduced the manufacture cost of bearing.
The structure of this patent and existing blower fan is complementary, and promptly the reforming cost to existing blower fan is low, and it is also convenient to transform, and needed expense is very low.
Description of drawings
Fig. 1 is the utility model structural representation;
1 column among the figure, the 2nd, support, the 3rd, clutch shaft bearing, 31 is second bearings, the 4th, input shaft, the 41st, output shaft, the 5th, Tooth wheel with changeable teeth case, the 6th, generator, the 7th, fan blade.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: a kind of wind-driven generator comprises column 1, support 2, clutch shaft bearing 3, the second bearings 31, input shaft 4, output shaft 41, generator 6, fan blade 7.
Described support in echelon, fixedlying connected with column in trapezoidal bottom surface, arranges convex key on the narrower end face, arranges clutch shaft bearing in convex key.
In this patent, according to the loading characteristic of horizontal axis blower fan, the work loads of managing to make bearing is balance as far as possible, to improve the stress of bearing.
Therefore, from this angle, make every effort to make the arm of force of fan blade the shortest.As can be seen from the figure, the moment of torsion of fan blade is delivered to the Tooth wheel with changeable teeth case by the blower fan input shaft, by the speedup of Tooth wheel with changeable teeth case, transfers torque to generator at last and generates electricity.Blower fan input shaft one has two bearings and supports, the position of one of them bearing as shown in the figure, another bearing is positioned at gear-box inside, by such topology layout, the maple leaf input shaft is become two point-supported structures approx from a cantilever layout, and the difference of its maximum is exactly that center of gravity with total is between two bearings.Cantilever structure has become two point-supported structures, makes its center of gravity between two bearings, thereby has improved the working state of bearing, has prolonged the life-span of bearing.
Gear-box 5 is Tooth wheel with changeable teeth casees.Be connected by gear-box 5 between input shaft 4 and the output shaft 41.
This patent is simple in structure, has reduced the usage requirement of bearing, thereby has reduced the manufacture cost of bearing; Be complementary with the structure of existing blower fan, promptly the reforming cost to existing blower fan is low, and it is also convenient to transform, and needed expense is very low.
