Description
Technical field
The new point of oil the present invention relates to pneumatic gearbox drive technical field, more particularly to a kind of wind turbine gearbox is filled
Put.
Background technology
Oil distribution device as the important component in wind turbine gearbox, with connection planet carrier（Revolving part）With casing
（Static element）Between oil circuit effect, weighed extensively because of its machining accuracy, sealing and wearability the requirement reason such as higher
Depending on.The oil distribution device of prior art includes casing 1, oil distributing ring baffle plate 2, oil distributing ring 3, planet carrier 6, oil duct 7（As shown in Figure 1）,
Wherein, oil distributing ring 3 is single design of part.In normal work, outside cutting oil enters a point oil by box house oil pipe
Ring, then cooling and lubricating part is needed to each into planet carrier internal oil pipe by oil distributing ring distribution.Oil distributing ring is generally and gear housing rigidity
Connection, in the presence of the gap of about 0.2~0.3 mm between planet carrier, by the relative motion of static element and revolving part, about 0.2
Aeroseal air cushion is formed in the gap of~0.3mm, to form seal oil chamber, enables cutting oil successfully from static element
Without a large amount of leakages in inflow revolving part.
Prior art has the following disadvantages：1. the gap of 0.2~0.3mm during real-world operation because vibration etc. original
Because being easily eliminated, cause planet carrier to be contacted with oil distributing ring, friction occurs and planet carrier is damaged；2. the gap of 0.2~0.3mm is too
It is small, more difficult during assembling, part of easily damaging；3. planet carrier is generally that casting or large forgings can not carry out nitrogen treatment, surface
Hardness is not high, therefore the material of oil distributing ring just must be softer than planet carrier, and planet carrier will not be ground in just can guarantee that actual motion
It is bad；4. copper alloy oil distributing ring is used, it is relatively costly；5. the processing to soft material is relatively difficult to ensure the required precision that card coordinates, and causes
Gap increases, leakage rate increase；6. soft material is easy to wear in use, causes leakage rate to increase.
The content of the invention
It is an object of the invention to overcome drawbacks described above, there is provided the wind-powered electricity generation that a kind of low cost, wearability are good, sealing property is high
The new oil distribution device of gear-box.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：A kind of new point of oil dress of wind turbine gearbox
Put, including casing 1, oil distributing ring baffle plate 2, upper oil distributing ring 3, metallic laminations sealing ring 4, lower oil distributing ring 5, planet carrier 6, oil distributing ring gear
Plate 2, upper oil distributing ring 3 are bolted on casing 1, and lower oil distributing ring 5 is bolted on planet carrier 6, metallic laminations
Sealing ring 4 is arranged in the seal groove of lower oil distributing ring 5, and is contacted with upper oil distributing ring 3, and upper oil distributing ring 3 is not direct with lower oil distributing ring 5
Contact, casing 1, upper oil distributing ring 3, the inner chamber UNICOM of lower oil distributing ring 5 constitute oil duct 7.
Preferably, the gap δ between upper oil distributing ring 3 and lower oil distributing ring 5 is 0.50~0.57mm.
The beneficial effect that apparatus of the present invention possess：1. because metallic laminations sealing ring has elasticity, in use, can not
Disconnected outwards top, until metallic laminations sealing ring is completely worn out or follows the string, it is ensured that sealing validity；2. new construction part can be adopted
With common used material, without using softer copper alloy, reduces cost；3. the equal via nitride treatment of mutually friction sealed part, increases
Plus wearability, improve service life；4. piece surface via nitride treatment, case depth is controlled in 0.3~0.5mm, can used
Grinding method is processed, it is ensured that parts size precision, reduces difficulty of processing；5. actual frictional dissipation is only produced inside oil distribution device
It is raw, the strength members such as planet carrier can be played a protective role.

Specific embodiment
Specific embodiment of the invention is described further below in conjunction with the accompanying drawings.
As shown in Fig. 2 the new oil distribution device of wind turbine gearbox includes oil distributing ring baffle plate 2, upper oil distributing ring 3, metallic laminations
Sealing ring 4, lower oil distributing ring 5, wherein, oil distributing ring baffle plate 2, upper oil distributing ring 3 are bolted on remains stationary on casing 1, under
Oil distributing ring 5 is bolted on planet carrier 6, can be rotated with planet carrier 6, and metallic laminations sealing ring 4 is arranged on lower point
In the seal groove of oil ring 5, and contacted with upper oil distributing ring 3.Casing 1, upper oil distributing ring 3, the inner chamber UNICOM of lower oil distributing ring 5 constitute oil duct
7.Metallic laminations sealing ring 4 has elasticity, operationally, with metallic laminations sealing ring 4 and the temperature arrising caused by friction of upper oil distributing ring 3, gold
Category lamination sealing ring 4 can be expanded to away from center of circle direction, and with seal groove in the inner headed face of upper oil distributing ring 3 and lower oil distributing ring 5
Cell wall is more in close contact, and forms annular seal space.Upper oil distributing ring 3 not with the lower directly contact of oil distributing ring 5, have one gap δ between the two, should
Gap control be in 0.50~0.57mm it is optimal, it is convenient for assembly.When planet carrier 6 starts to rotate, drive lower oil distributing ring 5 and
Metallic laminations sealing ring 4 in its seal groove rotates together.Upper oil distributing ring 3 and the treatment of the equal via nitride of lower oil distributing ring 5, hardened-depth
Degree control can reduce part difficulty of processing in 0.3~0.5mm by being ground precise control accessory size.
The present invention is not limited to above-mentioned implementation method, in the ken that art those of ordinary skill possesses
It is interior, can also be made a variety of changes on the premise of present inventive concept and principle is not departed from.
