Not constituting conflict can be combined with each other.
A kind of specific embodiment of wind-driven generator gear-box as provided by Fig. 1-2, including mutually it is arranged connection
Sun gear 2 and axle construction 5, the connection structure 6 between the sun gear 2 and the axle construction 5, the sun gear 2, institute
It states axle construction 5 and the connection structure 6 is enclosed the cavity 7 of permission lubricating oil entrance, formed in the connection structure 6
There is the outlet for allowing outflow of lubrication oil, and the lubricating oil is single towards the flowing of the export direction after entering the cavity 7
To.
Above-mentioned wind-driven generator gear-box, the antitorque connection each other of sun gear 2, axle construction 5 and connection structure 6, connection knot
Structure 6 is an integral molding structure with sun gear 2, is also to form in axle construction 5 to cooperate with the connection structure 6 on sun gear 2
There is spline compatible with connection structure 6, a storage lubricating oil is formd between sun gear 2, axle construction 5 and connection structure 6
The cavity 7 with pressure, under the effect of the pressure, lubricating oil is unidirectionally flowed out along the outlet of connection structure 6, i.e., will not flow back sky
In chamber 7, sun gear 2, axle construction 5 and connection structure 6 because caused by after phase mutual friction, abrasion small iron filings wash away, while it is right
The contact surface of sun gear 2, axle construction 5 and connection structure 6 plays the role of lubrication, effectively avoids because wearing the small of generation
The problem of particle is damaged caused by gear-box, is led to the premature component failure in gear-box, is influenced the service life of gear-box.
Cavity 7 is an annular chamber, and lubricating oil enters in cavity 7 from the oil sump of gear-box, entire cavity 7 is full of, to sky
The inner surface of chamber 7 is adequately washed away and is lubricated, and is flowed out under pressure from the outlet in connection structure 6, and is lubricated
Oil is one-way flow in cavity 7, in the cavity 7 that will not flow back, avoids that iron filings are washed away back and forth and what cannot be discharged ask
Topic.
The sun gear 2 radially forms protrusion 21 far from one end of the connection structure 6, and the protrusion 21 supports
It connects on end face of the axle construction 5 far from the connection structure 6.Protrusion 21 is radially formed at the middle part of sun gear 2,
End face of the axle construction 5 far from connection structure 6 is axially facing surface 8, part of the axially facing surface 8 far from sun gear 2 and protrusion
It is rigid connection between portion 21, and fitting completely, the outer wall certain distance apart from sun gear 2, to form cavity 7, in cavity 7
Lubricating oil also plays the effect to contact surface lubrication simultaneously, reduces the abrasion between protrusion 21 and axially facing surface 8.
The end face is equipped with the gap for allowing outflow of lubrication oil, and the lubricating oil is after entering the cavity 7 towards described
The flowing of gap direction is unidirectional.
Gear-box during real-world operation, sun gear 2 can opposite axle construction 5 generate slight wriggling, when wriggling, can produce
Raw abrasion and small gap after lubricating oil enters cavity 7, are sprayed from the axially facing surface 8 on protrusion 21 and axle construction 5
Out, to wash away the fine particle in axially facing surface 8, and the axially facing surface 8 is lubricated, prevented in axially facing surface 8
Small iron filings enter cavity.
Specifically, the connection structure 6 is spline.Spline coupling has the advantages that stress is more uniform；Because the number of teeth is more,
Total contact area is larger, therefore can bear biggish load, and the gap between the number of teeth forms the outlet of outflow of lubrication oil；Also
Have that guiding performance is good, and transmits the advantages that torque is big.
The axle construction 5 forms the first oil transportation channel 9,9 edge of the first oil transportation channel far from one end of the connection structure 6
Axle construction 5 radially extends, and first oil transportation channel 9 is respectively communicated with the import of the oil sump and the cavity 7 of gear-box.It is leaning on
Be equipped with the first oil transportation channel 9 through axle construction 5 at nearly axially facing surface 8, this first oil transportation channel 9 respectively with the oil of gear-box
Pond is connected with the import of cavity 7, and the lubricating oil of gear-box oil sump is supplied to cavity 7.
It further include the planet carrier 4 being set in the axle construction 5, planet carrier 4 is located remotely from the side of connection structure 6, institute
Planet carrier 4 is stated to be equipped with while being connected to the oil sump of the gear-box and the second oil transportation channel of first oil transportation channel 9.Specifically
Ground is additionally provided with a circular connector 10 between the outlet of second oil transportation channel and the import of first oil transportation channel 9.Tool
Body, the circular connector 10 is copper slip ring.Lubricating oil in gear-box oil sump is successively defeated through second under pressure
Oily channel, circular connector 10 and the first oil transportation channel 9 enter in cavity 7, and the finally outlet from connection structure 6 and sun gear
The gap of the axially facing surface 8 on protrusion 21 and axle construction 5 on 2 is flowed out, and is back in gear-box oil sump.
The slip ring has good wearability, low temperature resistant, high humility, anti-blown sand, corrosion-resistant, shock resistance, against shock, performance
The characteristics such as stabilization, Maintenance free, long service life are able to maintain effectively connecting between the first transfer passage and the second transfer passage
It connects.
The axle construction 5 radially forms a convex block 51 close to one end of the connection structure 6, forms on the convex block
Lubricating oil is allowed to be back to the aperture 52 of the oil sump of gear-box after the outlet outflow of the cavity 7.This aperture 52 is to flow out
The oil return hole of the lubricating oil reflux gear-box of cavity 7, the lubricating oil in cavity 7 are discharged by connection structure 6 by aperture 52, simultaneously
Also by sun gear 2, axle construction 2 and connection structure 6 because caused by after phase mutual friction, abrasion small iron filings wash away.
Lubricating oil in gear-box oil sump is under pressure successively through the second oil transportation channel, circular connector 10 and first
Oil transportation channel 9 enters in cavity 7, and finally from the protrusion 21 and axle construction 5 in the outlet of connection structure 6 and sun gear 2
Axially facing surface 8 gap outflow, be back in gear-box oil sump.In the process, lubricating oil not only can will be due to sky
What the friction between the protrusion 21 being radially formed of sun gear 2 and the connecting end surface of axle construction 5 caused by the molding of chamber 7 was formed
Iron filings wash away in time, also simultaneously during lubricating oil flows to outlet from the import of cavity 7, by sun gear 2,5 and of axle construction
The contact surface of connection structure 6 iron filings to be formed that rub are synchronized and are washed away, abrasion caused by avoiding small iron filings from assembling at spline position
Aggravation.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
