Description
Technical field
The present invention relates to field of wind power equipment, specifically a kind of wind-driven generator buffer-type main shaft.
Background technology
With continuing to develop for wind-power electricity generation, the installation amount of wind-driven generator is also greatly improved.But wind-force is sent out
The fault rate high of motor largely hinders the development of wind-power electricity generation.Studied for many years according to the fault diagnosis to wind-power electricity generation
Learn, the failure of wind-driven generator most reason is by random wind-induced impact to be directly delivered to gear-box and motor is made
Into.Because wind speed is uncontrollable, so the impact that wind speed causes is also inevitable.But can be by increasing buffering dress
Put, the impact in reduction power transmitting procedure to equipment, so as to reduce the fault rate of equipment.Main shaft is in wind power plant
Front end, if the main shaft of buffer-type can be designed, equipment that can be to after produces very big protection, reduces the failure of equipment
Rate.
Existing main shaft mainly plays gearing, and the impact that RANDOM WIND is produced directly is delivered to gear-box by main shaft, right
The gear of gear-box is impacted, and thereby results in gearbox fault rate higher relative to integral device.So improving main axle structure
Or increase buffer structure is necessary for wind-driven generator.
The content of the invention
In order to reduce the failure that RANDOM WIND impact causes, the present invention provides a kind of wind-driven generator buffer-type main shaft.
The technical scheme that the present invention solves the technical problem is to design a kind of wind-driven generator buffer-type main shaft, and it is special
Levy and be, the buffering main shaft mainly includes two main shafts, engagement wheel, ratchet wheel, spring, spring spindle and two bearing blocks；Engagement
Wheel splined end is connected with a main shaft, and the other end is connected with the end of engagement of ratchet wheel；Spring spindle is provided with spring mounting hole, spring
Inside it；The splined end of ratchet wheel is connected with another main shaft, is additionally provided with spring spindle mounting hole on the pawl of ratchet wheel in addition,
Spring spindle is arranged on inside it；In the hole inside spring spindle, another part is arranged on spring top to a spring part
In bar mounting hole；Two bearing blocks are separately mounted to two two ends of the main shaft for linking together.
Compared with prior art, the wind-driven generator buffer-type main shaft of present invention design is steady with simple structure, transmission
Calmly, the advantages of buffering effect is obvious, greatly reduces the abrasion of wind driven generator principal shaft, reduces the failure of wind-driven generator
Rate, with larger market application foreground.

Specific embodiment
The present invention is described in detail with reference to embodiment and its accompanying drawing.Embodiment is with technical scheme of the present invention as preceding
The specific implementation for carrying out is proposed, detailed implementation method and process is given.But claims hereof protection domain is not limited to
Following embodiment descriptions.
Present invention design is a kind of wind-driven generator buffer-type main shaft (referring to Fig. 1-6), it is characterised in that buffering master
Axle mainly includes two main shafts 1, engagement wheel 2, ratchet wheel 3, spring 4, spring spindle 5 and two bearing blocks 6；The spline of engagement wheel 2
End is connected with a main shaft 1, and the other end is engaged with the end of engagement of ratchet wheel 3；Spring spindle 5 is provided with spring mounting hole, and spring 4 is installed
Inside it；The splined end of ratchet wheel 3 is connected with another main shaft 1, is additionally provided with spring spindle mounting hole on the pawl of ratchet wheel 3 in addition,
Spring spindle 5 is arranged on inside it；In the hole inside spring spindle, another part is arranged on spring top to a spring part
In bar mounting hole；Two bearing blocks 6 are separately mounted to two two ends of the main shaft 1 for linking together.
Preferably, 2 spring spindles side by side are installed on the pawl of each ratchet wheel 3, more preferable buffering effect can be played.
When power is transferred to engagement wheel 2 from first paragraph main shaft 1, engagement wheel 2 is rotated, when turning to certain position and spring
Push rod 5 is contacted, and spring 4 compresses therewith, and finally engagement wheel 2 is contacted with ratchet wheel 3, and ratchet wheel 3 drives another section of main axis.This process
In the impact of second segment main shaft is buffered by spring-compressed.
The spring spindle is arranged in the spring spindle mounting hole of the pawl of ratchet wheel, and engagement wheel does not work the time-division with ratchet wheel
Open, transmission torque is engaged during work.Engagement wheel is contacted with spring spindle in the process, and spring-compressed plays cushioning effect.Two
Individual bearing block plays a part of axially position, prevents the structure in operation process from producing separation.Buffer spring is arranged on spring top
In bar, by direct impact of the spring buffer from engagement wheel；The coefficient of elasticity of spring is sufficiently large, when the transmission of no power
When, the pawl of ratchet wheel can be made to be separated with the pawl engaged on wheel, spring can play cushioning effect during so as to transmission next time；Ratchet wheel
With engage wheel axially and radially between to leave enough gaps, prevent their directly contacts from producing friction to be unfavorable for the work of spring
Make；Ratchet wheel passes through spline connection with wheel is engaged with each section of main shaft, and the procedure for reducing main shaft is more conducive to manufacture processing and pacifies
Dress；The pawl of ratchet wheel is provided with through hole, is easy to the installation and removal of spring and spring spindle；The top of spring spindle is than its bottom
Size is big, prevents spring spindle when work in the stuck spring spindle mounting hole on pawl, and buffering is not had later
Effect；The intensity of the pawl on ratchet wheel and engagement wheel is sufficiently large, and torque is excessive when preventing from transmitting, and produces fracture, loses more than gain.
The present invention does not address part and is applied to prior art.
