Description
Technical field
The utility model relates to the technical fields of wind-driven generator, refer in particular to half direct-drive type power dividing differential of one kind
Gear box structure.
Background technique
The gear-box that traditional wind group is partly directly driven uses traditional NGW type planetary gear train, mainly in order to meet tooth
The bearing capacity of wheel, the radial dimension and axial dimension of gear-box are required to be made big.But in real work, gear-box
Overall dimensions should not be too large, therefore under the limitation of the condition of identical weight and size, how make the power density of gear-box bigger
Change.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, propose a kind of half direct-drive type power dividing differential
Gear box structure, can guarantee gear-box the condition of identical weight and size limitation under, realize power density it is bigger, simultaneously
Security reliability improves.
To achieve the above object, a kind of technical solution provided by the utility model are as follows: half direct-drive type power dividing differential
Gear box structure, including gear-box ontology and using single biserial flange form main shaft bearing structure base bearing, but do not include master
Axis, the base bearing are built in gear-box ontology, for bearing the radial force and bending load that wind wheel passes over, are reduced and are handed over
Impact of the varying load to gear-box ontology, the hub side of the gear-box ontology are provided with hub side primary planet train, hair
Motor side is provided with generator side primary planet train, the gear-box ontology use planetary differential power dividing structure, respectively from
Hub side primary planet train and generator side primary planet train input power, wherein the hub side primary planet train
It is driven and is inputted by hub side gear ring, the generator side primary planet train is driven by generator side planet carrier and inputted, the wheel
Hub side primary planet train is connect by its hub side sun gear with generator side primary planet train, so that hub side one
The torque of grade is transferred to generator side planetary gear train through hub side sun gear, by the generator side of generator side primary planet train
Planetary gear synthesizes power, eventually by generator side sun gear by power transfer to generator.
The utility model compared with prior art, have the following advantages that with the utility model has the advantages that
1, the utility model does not have main shaft, by using half direct drive structure that base bearing and gear-box integrate, knot
Structure is compact.
2, the utility model shunts differential intermediate gear case using two stage power, is suitable for high-power wind turbine unit, structure
It is more compact.
3, the entire gear-box capacity density of the utility model is very high, can be by function under identical weight and size limitation
Rate improves 40% or more.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail combined with specific embodiments below.
It is shown in Figure 1, the gear box structure of half direct-drive type power dividing differential provided by the present embodiment, including gear
Case ontology 1 and the base bearing 2 for using single biserial flange form main shaft bearing structure, but do not include traditional main shaft, the base bearing 2
It is built in gear-box ontology 1, for bearing the radial force and bending load that wind wheel passes over, reduces alternating load to gear
The impact of case ontology 1, the hub side of gear-box ontology 1 are provided with hub side primary planet train 3, and generator side is provided with hair
Motor side primary planet train 4, which uses planetary differential power dividing structure, respectively from hub side level-one row
4 input power of star wheel series 3 and generator side primary planet train, wherein hub side primary planet train 3 is by hub side gear ring 31
Driving input, generator side primary planet train 4 are driven by generator side planet carrier 41 and are inputted, hub side primary planet train 3
It is connect by its hub side sun gear 32 with generator side primary planet train 4, so that the torque of hub side level-one is through taking turns
Hub side sun gear 32 is transferred to generator side planetary gear train 4, by the generator side planetary gear of generator side primary planet train 4
(not shown) synthesizes power, eventually by generator side sun gear 42 by power transfer to generator (not shown).
The power that such structure flows through in monopole planetary system is shunted, and realizes planetary structure gear-box capacity density bigizationner, peace
Full reliability improves, and has actual promotional value, is worthy to be popularized.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit the utility model with this
Practical range, therefore all shapes according to the utility model, change made by principle, it should all cover in the protection scope of the utility model
It is interior.
