Technical field
The present invention relates to a kind of power transmission device and a kind of wind energy conversion systems including this power transmission device.
Background technology
Currently, in multiple technical fields, the problem of power is transmitted between rotary rack and fixing end, example can be all encountered
Such as the trunnion axis on rotary rack and between fixing end transmit power the problem of.Wherein, rack can rotate, so as to
To adjust the angle position that trunnion axis surrounds vertical pivot, but usually the rotation of rotary rack, can not be complete by a variety of limitations
It rotates freely through.For example, in high-level crane, motor is installed below high-level control room, is enclosed with drive control room and arm
Spinning movement is done around tower body, in order to transmit electric power to motor and need to be laid with cable upwardly from ground.Cable is because excessively turning round in order to prevent
Then be damaged, control room and arm cannot do unconfined rotation.
Especially in wind-driven generator field, there are the above problem, nothing cannot be done between the head and pylon of wind-driven generator
The rotation of limitation.
And wind energy receives the attention of countries in the world as excellent clean energy resource.Wind-driven generator used at present is logical
Include often wind wheel, machine driven system (such as speed increaser) and generator etc..Wind wheel rotates under the action of the forces of the wind, is obtained
Kinetic energy passes to generator through machine driven system, and electric energy is converted kinetic energy by generator.Machine driven system and generator
It is encapsulated in a cabin, tower top is then mounted on by rotary supporting device, constitutes the head of wind-driven generator.
Head, the head of especially large and medium-sized wind-driven generator, weight is very big, can reach tens of tons to hundreds of tons.Therefore, right
The requirement of rotary supporting device is high, and the manufacturing cost for causing rotary supporting device is high.Heavy head needs special
Machinery surveys wind and to wind apparatus, further increases the volume, weight and structural complexity of head.The weight and volume of head is given
Transport and installation also bring many difficulties.On the other hand, since generator is mounted on the wind in the cabin of rotation, for
The cable to transmit electric power outside may be there is a phenomenon where twisting, so wind-driven generator also needs to installation and unties the mooring rope and turn round cable accordingly
Protective device.As it can be seen that current wind-driven generator structure is complicated, manufacture, transportation, installation, maintenance etc. cost very
Greatly, become one of the factor for hindering wind energy to utilize extensively.
According to National Energy Board it is newest print and distribute about wind-powered electricity generation implementation management in relation to require notice, increase newly centralization it is land
The offshore wind farm project of Wind Power Project and not determining investment subject all should be configured and be determined rate for incorporation into the power network by competitive way.In
State's regenerative resource industry opens a new epoch, surfs the Net at a competitive price and brings new challenge and opportunity.This management method
The planning ensured under the premise of consumption is clearly proposed, persistent ailment of rationing the power supply at least will alleviate new projects significantly.It optimizes industry environment,
Squeeze numerous parasitic interests links on very long wind power value chain so that the further regression technique essence of Wind Power Generation.Meanwhile
The challenge that wind-powered electricity generation enterprise will also face rate for incorporation into the power network keen competition and bring.

Preferred embodiment in, between another gear 52 and differential mechanism shell 63 be provided with two-stage gear drive.
Here, the rotating ratio of the ring gear 71 and the differential mechanism shell 63 is 2:1, thus make the rack 7 and institute
It is 2 to state the ratio between rotating speed of differential mechanism shell 63:1.In this way, the rotation exported at the second semiaxis 62 of differential mechanism 6
It is only related around the rotation of horizontal axis with the trunnion axis 2, and with the rotation of the output shaft of the motor 5 or say and institute
The rotation that trunnion axis 2 is stated around vertical axis is unrelated.
The rotation of second semiaxis 62 of the differential mechanism 6 continues to be transferred to Near Ground, via another column gear transmission
Mechanism 11 and another bevel gear transmission 12 make second semiaxis be converted to around trunnion axis around the rotation of vertical axis
The rotation of line then drives generator G power generations.Similarly, can generator G be replaced with into pump, such as water pump or oil as needed
Pump etc..
If the vertical axes for transmitting the rotation of trunnion axis downwards are long, more sections of axis can be divided into, pass through shaft coupling
Device connects it as an axis, as shown in FIG. 5.
Similarly with the embodiment of Fig. 4 and wind energy conversion system shown in fig. 5, power transmission device that can be shown in Fig. 3
Fan blade is installed on trunnion axis, trunnion axis rotation is driven by fan blade, then will be passed under the rotation of fan blade via the power transmission device
To Near Ground, electrical power generators or transfer tube operating are driven.
Protection scope of the present invention is only defined by the claims.Have benefited from the teachings of the present invention, those skilled in the art hold
Easily recognizing can be using the alternative structure of presently disclosed structure as feasible alternate embodiments, and can be by institute of the present invention
Disclosed embodiment is combined to generate new embodiment, or applies the present invention to other similar fields, it
