Abstract
The utility model provides a wind generator set supported by double bearings. The wind generator set supported by the double bearings comprises a wind wheel, a gearbox, a rear bearing pedestal, a shaft coupler, a generator, a rack, a main shaft, a tower drum, two elastic supports, a front bearing pedestal, a front bearing and a rear bearing, wherein the main shaft sequentially penetrates through the front bearing, the gearbox and the rear bearing, so that the main shaft can freely rotate around the axis of the main shaft. The front bearing and the rear bearing are installed on the rack in a supported mode through the front bearing pedestal and the rear bearing pedestal respectively. The front bearing and the rear bearing are self-aligning bearings. The wind wheel is installed at the front end of the mains shaft. The generator is connected with the gearbox through the shaft coupler, so that torque is transmitted. The two sides of the gearbox are connected with the rack through the two elastic supports. The rack is installed at the top of the tower drum. Due to the fact that the structure is adopted on the gearbox of the wind generator set, only a torque effect of the wind wheel is borne, fatigue loads of the bearings inside the gearbox are greatly reduced, and according to the scheme, the wind generator set supported by the double bearings is simple in structure, low in cost and beneficial to large-scale popularization.
Description
Technical field
The utility model relates to technical field of wind power generation, is specially the wind power generating set that a kind of duplex bearing supports.
Background technique
As everyone knows, popular horizontal axis double-fed wind power generator group mostly is the bikini support greatly at present, and front-end of spindle is connected with frame by a bearing, and tail end and gear-box are rigidly connected, and the gear-box both sides are connected with frame by elastic support, constitute supported at three point.Yet, adopting this kind structure, gear-box not only needs to bear torque load, also needs to carry additional load such as moment of flexure, thrust, makes the rate of fault of gear-box improve greatly.
The model utility content
Model utility purpose: provide a kind of wind power generating set of duplex bearing support to address the above problem, make the gear-box of wind power generating set only bear torsional interaction.
Technological scheme: the utility model is achieved through the following technical solutions:
The wind power generating set that a kind of duplex bearing supports, comprise wind wheel, gear-box, rear bearing block, coupling, generator, frame, main shaft, tower tube, two elastic support, front-end bearing pedestal, fore bearing and rear bearings, it is characterized in that: main shaft passes fore bearing, gear-box and rear bearing successively; Described fore bearing and rear bearing support by front-end bearing pedestal and rear bearing block respectively and are installed on the frame, and frame is installed on the top of tower tube; The front end of described main shaft is equipped with wind wheel; Described generator is connected with gear-box by coupling, transmits moment of torsion.
Described gear-box both sides are connected with frame by two elastic support.
Described fore bearing and rear bearing all are selfaligning bearing.
Beneficial effect
Adopt the beneficial effect of technique scheme to be:
1. the wind power generating set that adopts the utility model to provide, gear-box is only born the torsional interaction of wind wheel, reduces the fatigue load of gear-box internal bearings greatly;
2. the not outer moment of flexure effect of commitment of gear-box, the axle of gear-box does not have radial deformation, has reduced greatly because the probability that the gear wear that radial deformation causes is accelerated.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that Fig. 1 is along the partial sectional view of main-shaft axis;
