Description
Technical field
The utility model is related to a kind of radiating mode of gear-box, especially a kind of wind turbine gearbox of self-reinforcing heat dissipation,
Belong to machinery field.
Background technology
In the gear-box of wind-driven generator, the type of cooling of gear-box is all to take the lubricating oil type of cooling, especially
For large-scale wind-driven generator wheel-box, generally requires to set up independent lubricating oil station, be radiated in vitro to lubricating oil cold
But, for the mode of external lubricating oil cooling it is current there are mainly two types of：Lubricating oil to drawing babinet takes water cooling and wind
Cold form heat dissipation.Two kinds of cooling heat-removal modalities cut both ways：Water-cooled effect is preferable, but needs a set of additional air cooler
Recirculated water is cooled down, while also needing to the lubricating oil of complete set and system that water carries out cold and hot exchange, these are corresponding
Measure inevitably results in cost and increases very much.Air-cooled is the common cooling measure that current wind turbine gearbox is directed to that lubricating oil is taken,
The air-cooled fuel feeding and cooling system for being also required to configuration complete set, especially in the case where heat radiation power is larger, it is necessary to select
Select the forced air cooler of larger specification.
Usual fan engine room space is compact narrow, so relying solely on the lubricating system after traditional air-cooled or water cooling
Gear-box is cooled down, while being aided with the citation form of tank surface natural heat dissipation, in many cases（Especially midsummer）It is nothing
Method reaches or meets the main technique requirements of gear-box work, how to be solved in face of these actual states, it has also become this field is close
The technical issues of cutting concern.
Utility model content
The purpose of this utility model is that：It is multiple that existing lubricating oil cooling system structure is cooled down for current wind turbine gearbox
It is miscellaneous, and only rely on lubricating oil cooling system and cannot be satisfied a series of problems, such as technology requires in many cases, it provides a kind of new
Self-reinforcing heat dissipation wind turbine gearbox.
What the purpose of this utility model was realized in：A kind of wind turbine gearbox of self-reinforcing heat dissipation, including gear-box are total
At, it is characterised in that：High speed shaft in gearbox assembly is stretched out the babinet of gearbox assembly by front end, is furnished with wind on high speed shaft
The surface of fan, babinet is equipped with wind guide tank, and wind guide tank extends by babinet front end face along tank surface to the back-end；The fan packet
Axle sleeve, fan frame and flabellum are included, fan frame is evenly distributed on the periphery of axle sleeve, and flabellum is fixed on fan frame；The fan, which is furnished with, leads
Wind shield, fans frame and flabellum is placed in wind-guiding shield and is solidified as a whole with the high speed shaft for stretching out babinet by key by axle sleeve.
In the present invention, the fan diameter is less than the sectional area of gearbox assembly front end, and wind-guiding shield goes out
It is directed toward the wind guide tank of casing end face in air port.
In the present invention, the wind-guiding shield is fixed by the bracket on the babinet of gearbox assembly, high speed shaft
The end input axis connection that passes through shaft coupling and wind-driven generator.The lubricating oil of gearbox assembly uses air-cooled or water-cooling
Mode cools down.
The utility model has the advantage of：Since the high speed shaft in gearbox assembly is by the case of front end stretching gearbox assembly
Body is furnished with fan on high speed shaft, and the surface of babinet is equipped with wind guide tank, and wind guide tank is by babinet front end face ing along tank surface rear end
Extend, wind guide tank can increase the surface radiating area of gear-box, and fan can improve the flow velocity of babinet ambient air, high speed
Air-flow can take away rapidly the heat for collecting tank surface, reduce rapidly the operating temperature of gear-box.It is led due to being furnished in fan
Wind shield can provide security protection for flabellum.Since fan is mounted in high speed shaft end, and its diameter is less than gear-box
Assembly end cross-sectional is accumulated, and the air outlet of wind-guiding shield is directed toward the wind guide tank of casing end face, not only compact-sized, easy to maintain, and
And wind gathering is with obvious effects.The utility model can be used for being operated on the wind turbine gearbox of small space, and can meet lubrication
Oil uses the gear-box of the different types of cooling.

Fig. 2 is the structural schematic diagram of the combination installation of the utility model.
Fig. 3 is the utility model embodiment structural schematic diagram after assembling.
In figure：1, axle sleeve, 2, fan frame, 3, flabellum, 4, gearbox assembly, 5, high speed shaft, 6, wind guide tank, 7, wind-guiding shield,
8, key.
Specific implementation mode
Attached drawing discloses the structural schematic diagram of the utility model embodiment without limitation, below in conjunction with the accompanying drawings to this practicality
It is novel to be further described.
As seen from Figure 1, fan includes axle sleeve 1, fan frame 2 and flabellum 3, and fan frame 2 is evenly distributed on the periphery of axle sleeve 1, flabellum 3
It is fixed on fan frame 2.
By Fig. 2 and Fig. 3 as it can be seen that the high speed shaft 5 in gearbox assembly 4 is stretched out the babinet of gearbox assembly 4, high speed by front end
5 end of axis is furnished with fan, and the surface of babinet is equipped with wind guide tank 6, and wind guide tank 6 prolongs by babinet front end face along tank surface to the back-end
It stretches.The fan is furnished with wind-guiding shield 7, fans frame 2 and flabellum 3 is placed in wind-guiding shield 7 and passes through key 8 and stretching by axle sleeve 1
The high speed shaft 5 of babinet is solidified as a whole.
In the present embodiment, the fan diameter is less than the sectional area of 4 front end of gearbox assembly, and wind-guiding shield 7 goes out
It is directed toward the wind guide tank 6 of casing end face in air port.When specifically used, the end of high speed shaft 5 is defeated by shaft coupling and wind-driven generator
Enter axis connection.Driving fan and wind-driven generator are synchronized when high speed shaft 5 works.
