Description
Technical field
The utility model relates to a kind of flexible shaft structure in Oversea wind power generation gear-box, belongs to a kind of dynamic
Power drive mechanism.
Background technology
With the rise of offshore wind farm, the wind power generating set power of installation is incrementally increased, and wind generating technology is proposed
One new height, it is desirable to which the small volume of wind power generating set, low cost, reliability are high.And offshore wind farm gear-box is wind
Power generator assembles an important mechanical part of set, to have high power density and lightweight demand also to become to get over to gear-box
Come more urgent.
On the one hand, traditional wind turbine gearbox is made up of secondary planetary gear transmission and the transmission of one-level parallel-axes gears, its
Middle planetary stage typically has 3~4 planetary gears, and planet axis are to rigidly fix with planet carrier, 2 supporting constructions is constituted, with gear
The increase of case power, the volume and weight of gear-box is all very big, it is impossible to meet the demand for development of offshore wind farm gear-box.Therefore,
We need a kind of many planetary gear transmission mechanisms of research, while needing to solve many Planetary Gear Transmissions using flexible shaft structure
Carry problem.On the other hand, existing flexible shaft structure includes：Compliant pin 1, planet axis 2, nut 3, locking nut 7, planetary gear
5th, planet carrier 6, bearing 4, as shown in Figure 1.Carried in the limit for bearing this offshore wind farm gear-box using this flexible shaft structure
Occur that the deflection to compliant pin 1 is not limited or can produce a kind of axial direction using compliant pin deformation during conical ring limit for tonnage during lotus
Power, this unconfined deformation or axial force can increase the damage ratio of part in flexible shaft structure, bearing, reduce gear-box
Life-span.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and providing one kind can preferably solve multirow
The problems such as compliant pin unrestrictedly deforms or produces axial force when deforming in star gear-driven load, existing flexible shaft structure, energy
Gear-box capacity density is improved, increases gearbox life, meet offshore wind farm gear-box small volume, lightweight, reliability high
The features such as the flexible shaft structure for offshore wind farm gear-box.
The purpose of this utility model is a kind of for the soft of offshore wind farm gear-box by following technical solution completing
Property axle construction, it is mainly by compliant pin, circlip, flexible guide, planet carrier, planetary gear, bearing, locking nut, planet
Axle is constituted, it is characterised in that described compliant pin is set with planet carrier hole, and compliant pin is arranged in a planet axis, in planet axis
On the planetary gear that can be engaged with sun gear and ring gear is provided with by bearing, the compliant pin circlip is fixed on soft
Property guide in and constitute a cantilever design.
As preferred：Described flexible guide is connected with planet carrier interference, and by the connecing at the A of the face of cylinder with planet axis
Touch the overload deformation for limiting compliant pin；Locking nut is configured with described planet axis, and the locking nut fixes on bearing
In the planet axis.
This utility model preferably solves that many planet gear transmissions are carried, compliant pin unrestrictedly deforms in existing flexible shaft structure
Or gear-box capacity density can be improved the problems such as generation axial force during deformation, and increase gearbox life, meet offshore wind farm tooth
Roller box small volume, the features such as lightweight, reliability is high.
Using many epicyclic gearboxes of the flexible shaft structure, the dislocation of planetary gear engagement on the one hand can be substantially reduced
Amount, being automatically adjusted by compliant pin makes each planetary gear bearing capacity identical；On the other hand compliant pin is limited by flexible guide
Overload deformation, and do not produce axial force, reduce part, the damage ratio of bearing in flexible shaft structure；Above-mentioned functions are improved
Life-span of offshore wind farm gear-box.
Description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Specific embodiment
This utility model is described in detail below in conjunction with accompanying drawing：Shown in Fig. 2, this utility model is a kind of for sea
The flexible shaft structure of wind turbine gearbox, it is mainly by compliant pin 11, circlip 12, flexible guide 13, planet carrier 14, planet tooth
Wheel 15, bearing 16, locking nut 17, planet axis 18 are constituted, and described flexible guide 13 loads in the hole of planet carrier 14, compliant pin 11
In a planet axis 18, the planet tooth that can be engaged with sun gear and ring gear is provided with by bearing 16 in planet axis 18
Wheel 15, the circlip 12 of the compliant pin 11 is fixed in flexible guide 13 and constitutes a cantilever design.
Shown in figure, described flexible guide 13 is connected with the interference of planet carrier 14, and by with planet axis 18 in face of cylinder A
The contact at place limits the overload deformation of compliant pin 11；Locking nut 17, and the locking screw are configured with described planet axis 18
Female 17 are fixed on bearing 16 in the planet axis 18.
It is described by compliant pin 11, circlip 12, flexible guide 13, planet carrier 14, planetary gear 15, bearing 16, lock
The flexible shaft structure of tight nut 17, the composition of planet axis 18, each planet tooth when can make that planetary gear is engaged in multirow star wheel gear box
Wheel bearing capacity is identical, improves the life-span of offshore wind farm gear-box.
In a particular embodiment, flexible shaft structure is adopted, as shown in Fig. 2 when planetary gear is engaged with ring gear, sun gear
When produce the force of periphery, be deformed compliant pin by bearing, planet axis stress, different deformations are produced according to the size of power
Amount, it is identical so as to automatically adjust the bearing capacity that makes each planetary gear, therefore also ensure that the life-span of offshore wind farm gear-box.Work as tooth
When roller box bears overload, planetary engagement force also increases, and causes the deformation that compliant pin is bigger, makes flexible guide and planet axis
Gap at the A of the face of cylinder is decreased to contact, so as to limit the deformation of compliant pin by flexible guide, it is ensured that flexible shaft structure
The life-span of middle part, bearing.
