Description
Technical field
The utility model relates to a kind of novel wind generator group gear-box torque arm damper mechanism.
Background technique
Gear-box is one of critical component of wind power generating set; Engagement between its working procedure middle gear can produce vibration and noise; Wheel hub goes out also and can arrive gear-box through the main shaft transmitting vibrations simultaneously; The torsional interaction of wind wheel transmission makes and the displacement that twists of whole Transmitted chains also can cause the decline of transmission efficiency in addition.In the face of generally can all adding the torque arm vibration damping on gear-box, this situation reduces vibration.The torque arm system can well improve the working environment of each transmission part, prolongs the working life of blower fan gear-box, guarantees transmission efficiency.But there is following deficiency in the gear box vibration damping scheme in usefulness at present:
1, the gear-box elastic support is undesirable to the restraining force vibration isolating effect that nodding causes.
2, the elastic support installation difficulty is big, inconvenient later maintenance.
3, higher to the processing request of gear box casing.
In view of these problems relevant with existing technology, the purpose of the utility model is to provide a kind of rational in infrastructure, in light weight, low cost of manufacture, novel wind power unit gear-box torque arm damper mechanism that reliability is high.
Summary of the invention
The utility model provides a kind of novel wind-driven generator group wheel box torque arm damper mechanism; Can bear bigger torsional load; Simultaneously can reduce the restraining force that the gear-box nodding causes to greatest extent; With compare in the gear box vibration damping scheme of usefulness at present, improved the working stability of gear-box, reduced vibration and noise.
For solving the technical problem that exists in the above-mentioned background technology; A kind of wind-driven generator group wheel box torque arm damper mechanism of the utility model; Comprise gear-box, gear-box and torque arm link together, and said torque arm is connected with torque axis through the moment of torsion vibration damping; Two bearings cooperated with bearing support about said torque axis passed through, and said bearing support is fixed on the gear-box frame.
Wherein, Be provided with taper in the said moment of torsion vibration damping; Be oppositely arranged and fix with the taper pole of moment of torsion vibration damping; Last rubber body is located at the said taper and the taper pole outside respectively with following rubber body, and the inverted concave shell pushes the side that is fixed on taper and taper pole with the said rubber body that goes up with following rubber body.
Wherein, said gear-box and torque arm link together through bearing pin.
Wherein, said torque axis is connected with the moment of torsion vibration damping through bearing pin.
Wherein, said bearing support is through on the gear-box frame that is bolted to the below.
Wherein, said inverted concave shell and torque arm are fixed.
The utility model beneficial effect: this damper mechanism working stability is better, and cost is low, and is easy to maintenance, is a kind of more reasonable and practical new departure.

Embodiment
Can be understood better for the shape, structure and the characteristics that make the utility model, below will enumerate preferred embodiment and combine accompanying drawing to be elaborated.
The torque arm vibration insulating system mainly contains 4 big critical components and forms: bearing support 4, torque axis 5, torque arm 2, moment of torsion vibration damping 3.As shown in the figure; Gear-box 1 links together through bearing pin 8 with torque arm 2; Bearing support 4 is through on the gear-box frame that is bolted to the below; Two bearings cooperated with bearing support 4 about torque axis 5 passed through, and torque axis 5 is connected with moment of torsion vibration damping 3 through bearing pin 8, and torque arm 2 is connected with torque axis 5 through moment of torsion vibration damping 3.
Be provided with taper 9 in the moment of torsion vibration damping 3, be oppositely arranged with taper poles 11 in the moment of torsion vibration damping 3 and pass through bolt.Last rubber body 7 is located at the taper 9 and taper pole 11 outsides respectively with following rubber body 6, and inverted concave shell 10 will be gone up rubber body 7 and push the side that is fixed on taper 9 and taper pole with following rubber body 8.Inverted concave shell 10 is fixing with torque arm 2.
When gear-box twists vibration; Upper and lower rubber body in the damper unit in the damper mechanism shearing force with draw high under the compression force; Resiliently deformable taking place, vibration is converted into the elastic potential energy and the heat energy of elastic support, has also limited the torsional deflection of gear-box when having reduced vibration.
When gear-box generation nodding; Upper and lower rubber body in the damper unit in the damper mechanism is drawing high under the compression force; Resiliently deformable takes place; Partial vibration is converted into the elastic potential energy and the heat energy of elastic support, and another part vibration reduces vibration through the buffering of the frictional rotation between torque axis and the bearing support.
When gear-box generation yawing, resiliently deformable takes place in the upper and lower rubber body in the damper unit in the damper mechanism under shearing and compression force, vibration is converted into the elastic potential energy and the heat energy of rubber body.
More than be illustrative to the description of the utility model; And it is nonrestrictive; Those skilled in the art is understood, and within spirit that claim limits and scope, can carry out many modifications, variation or equivalence to it, but they will fall in the protection domain of the utility model all.
