Description

A kind of wind-driven generator with shaft coupling

Technical field

Wind power generating set is in field high altitude at present, works under the conditions of unmanned.Bearing in Wind turbines, gear Case, blade is three big fragile parts.Main shaft bearing is unit critical component, is subjected to driving section deadweight, at wind-force Under wind direction effect, during operation, produce the biggest vibration, main shaft bearing thus bear bigger dynamic loading, and be in continuously work for a long time State；Working condition is very poor.Wind power generating set all uses tradition self-aligning roller bearing the most both at home and abroad.Must be at glossy draw runner Ability trouble free service under part, therefore require strictly to maintain condition.Because being positioned at aloft work, limited by many unfavorable conditions, regulation of mental activities Roller bearing often can not get daily oiling maintaining, easily damages when running under oil-free situation, and security reliability is poor, makes Short with the life-span.Additionally mounted dismounting is the most cumbersome, requires higher to bearing block, to this end, we are badly in need of design one with shaft coupling The wind-driven generator of device, solves the problems referred to above.

Background technology

Utility model content

The purpose of this utility model is to solve shortcoming present in prior art, and the one proposed is with shaft coupling Wind-driven generator.

To achieve these goals, this utility model adopts the technical scheme that

A kind of wind-driven generator with shaft coupling, including support tower, the upper end of described support tower connects the one of flange End, the other end of described flange is fixing connects cabinet, and one end of described cabinet is provided with tail vane, and described cabinet is away from one end of tail vane Connecting has shaft coupling, described shaft coupling to include driving shaft and driven shaft, and the driven shaft of described shaft coupling connects blade, described leaf The quantity of sheet is set to 3-5 sheet, is respectively equipped with hydraulic system, high speed shaft, electromotor, electromotor and Electronic Control in described cabinet Device, one end of described high speed shaft is rotationally connected electromotor, and the other end of described high speed shaft is rotationally connected the driving shaft of shaft coupling, institute State electronic controller electrical connection electromotor.

Preferably, the measurement of described blade a length of 15-25 rice.

Preferably, the highest peripheral speed of described shaft coupling is 40-60m/s, the employing number of described shaft coupling or number grease profit Sliding.

Preferably, the outfan electrical connection accumulator of described electromotor.

This utility model is provided with shaft coupling by the one end away from tail vane at cabinet, by the driven axle head of shaft coupling Connecting blade, wind energy is gone out to deliver to the rotating shaft end of electromotor by blade by shaft coupling, thus carries out power generation operation, by installing Shaft coupling, instead of traditional self-aligning roller bearing, this utility model, and simple in construction is reasonable in design, greatly enhances Generating efficiency and the service life of rotating shaft.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of wind-driven generator with shaft coupling that the utility model proposes.

In figure: 1 support tower, 2 blades, 3 shaft couplings, 4 cabinets, 5 tail vanes, 6 flanges.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.

With reference to Fig. 1, a kind of wind-driven generator with shaft coupling, including support tower 1, the upper end of support tower 1 connects method One end of blue 6, the other end of flange 6 is fixing connects cabinet 4, and one end of cabinet 4 is provided with tail vane 5, and cabinet 4 is away from the one of tail vane 5 End connection has shaft coupling 3, the highest peripheral speed of shaft coupling 3 to be 40-60m/s, and shaft coupling 3 uses No. 2 or No. 3 grease lubrications, Consumption, for filling shaft coupling, can effectively extend its service life, and shaft coupling 3 includes driving shaft and driven shaft, shaft coupling 3 from Moving axis connects blade 2, and the measurement a length of 10-25 rice of blade 2, the quantity of blade 2 is set to 3-5 sheet, is respectively equipped with in cabinet 4 Hydraulic system, high speed shaft, electromotor, electromotor and electronic controller, one end of high speed shaft is rotationally connected electromotor, high speed shaft The other end is rotationally connected the driving shaft of shaft coupling 3, electronic controller electrical connection electromotor, the outfan electrical connection electric power storage of electromotor Pond.

Operation principle: be provided with shaft coupling by the one end away from tail vane at cabinet in this utility model, pass through shaft coupling Driven axle head connect blade, wind energy is gone out to deliver to the rotating shaft end of electromotor by blade by shaft coupling, thus carries out the work that generates electricity Making, one end of high speed shaft is rotationally connected electromotor, and the other end of high speed shaft is rotationally connected the driving shaft of shaft coupling 3, Electronic Control Device electrical connection electromotor, the outfan electrical connection accumulator of electromotor, by installing shaft coupling 3, instead of traditional regulation of mental activities rolling Sub-bearing, this utility model, simple in construction, reasonable in design, greatly enhance the service life of generating efficiency and rotating shaft.

The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality Novel technical scheme and utility model thereof conceive equivalent or change in addition, all should contain at protection model of the present utility model Within enclosing.
