Description
Technical field
The utility model relates to gear-boxes, are related to a kind of wind turbine gearbox with ring gear lubrication system.
Background technique
Wind energy is one of the most abundant renewable energy in the world.Blower rotates under the promotion of wind energy, continuously
Export electric energy.This reproducible using energy source mode has all obtained rapidly developing in the whole world in the past few years.Drive generator
The wind turbine gearbox of operating can be described as the heart of gear drive type blower, due to the normal operation to whole system to Guan Chong
It wants.For wind turbine gearbox, lubricating system is most important, and wind turbine gearbox is able to maintain wind power gear under lubricant environment
Case works normally, and when due to wind turbine gearbox work, generates very big torque, once therefore gear-box lack lubricating oil, gear
Between cog interaction force in case is very big, causes tooth broken, gear-box is caused to damage.
Existing gear-box is needed for the pressure oil of lubrication by ring gear and preceding cabinet faying face, and preposition atomizer is with before
Cabinet connection, postposition atomizer and rear box joint face cause in this way the case where many places tie point generates leakage of oil；While by
All be in preposition atomizer, postposition atomizer and ring gear it is fixed, the fixed point of some on ring gear can only be carried out
Oil jet lubrication.
Utility model content
Purpose of utility model: the purpose of the utility model is to provide a kind of wind power gears with ring gear lubrication system
Case solves the Leakage of external atomizer Yu cabinet threaded connection place using internal atomizer；Even if there is slight infiltration simultaneously
Oil, oil liquid also only leak inside gear-box, not will cause external contamination and oil volume of gear box is reduced.
Technical solution: the wind turbine gearbox described in the utility model with ring gear lubrication system, including cabinet, cabinet
Built-in ring gear and and the planet carrier in cabinet and with ring gear cooperation is set；It is provided on planet carrier for oil inlet
Annular groove is provided with the oil inlet passage communicated with annular groove in planet carrier, and oil inlet passage is communicated with atomizer, and atomizer is arranged in planet
Expose at the top of planet carrier and atomizer on frame and as planet carrier rotates, at the top of atomizer towards at planet carrier and ring gear cooperation
Oil spout.
By using above-mentioned technical proposal, cabinet and ring gear pass through screw thread and connect with fixation, atomizer is bolted
It connects and is mounted on planet carrier, lubricating oil enters the annular groove of planet carrier right side by oil circuit, then enters oil inlet passage from annular groove, so
Enter atomizer afterwards, finally from atomizer to planet carrier and ring gear flank of tooth oil spout.
The utility model has the advantages that atomizer can together with planet carrier 360 ° rotation, can guarantee that each flank of tooth of ring gear has enough
Lubricating oil forms oil film, to guarantee the contact strength of the flank of tooth；Two parallel sections are devised in atomizer outer circle, using pulling
Hand can have good impetus when tightening atomizer；Atomizer oil inlet oil circuit and sun gear oil spout oil circuit are from an oil inlet
Branch in channel reduces the quantity of elongated oilhole on planet carrier, reduces difficulty of processing, saves processing cost.
Detailed description of the invention
Fig. 1 is the partial schematic diagram of the wind turbine gearbox cross-sectional view of the utility model；
Fig. 2 is the cross-sectional view of wind turbine gearbox the removal cabinet and ring gear of the utility model；
Fig. 3 is the enlarged drawing at the A in Fig. 2.
Specific embodiment
As illustrated in fig. 1 and 2, a kind of wind turbine gearbox with ring gear lubrication system, including built in cabinet 1, cabinet 1
Ring gear 2 and and the planet carrier 3 that is arranged in cabinet 1 and cooperates with ring gear 2；It is provided on planet carrier 3 for oil inlet
Annular groove 4 is provided with the oil inlet passage 5 communicated with annular groove 4 in planet carrier 3, and oil inlet passage 5 is communicated with atomizer 6, and atomizer 6 is set
It sets on planet carrier 3 and as planet carrier 3 rotates, exposes at the top of planet carrier 3 and atomizer 6 at the top of atomizer 6 towards planet carrier 3
With oil spout at 2 cooperation of ring gear.Cabinet 1 and ring gear 2 and fixation is bolted, atomizer 6 is connected through a screw thread installation
On planet carrier 3, lubricating oil enters the annular groove 4 of 3 right side of planet carrier by oil circuit, then enters oil inlet passage 5 from annular groove 4, so
Enter atomizer 6 afterwards, finally from atomizer 6 to 2 flank of tooth oil spout of planet carrier 3 and ring gear.Due to 6 oil inlet passage 5 of atomizer with
Sun gear oil inlet passage 5 is the branch from an oilhole, reduces the quantity of elongated oilhole on planet carrier 3, reduces processing
Difficulty saves processing cost.
As shown in figure 3, atomizer 6 and planet carrier 3 are threadedly coupled, and it is provided between atomizer 6 and planet carrier 3 for close
Sealing 7.Therefore lubricating oil can be effectively prevented to reveal from threaded connection place, so as to cause oil pressure reduction.
Since atomizer 6 and planet carrier 3 rotate together at runtime, to prevent the screw thread between atomizer 6 and planet carrier 3
It loosens and 6 oil spout direction of atomizer is caused to change or even fall off from planet carrier 3, atomizer 6 is provided with for axial limiting
Axial retaining ring 8 is provided in planet carrier 3 for axial retaining ring 8, there are the counterbores 9 of fitting allowance；9 diameter of counterbore can guarantee axis
There are enough assembly spaces with retaining ring, when assembly, first atomizer 6 is screwed into planet carrier 3, by adjusting depth is threaded into
Degree, after adjusting oil spout direction, shaft block ring is fitted into the annular groove 4 on atomizer 6, to carry out axial limit to atomizer 6
Position, and reach and prevent thread looseness and 6 oil spout direction of atomizer is caused to change.
The top of atomizer 6 is provided with the annular lug 10 for being held by planet carrier 3.In order to make assembly tighten atomizer
6 screw threads are more convenient, and the opposed stress surface 11 in left and right is specially provided on annular lug 10, make to screw up with a wrench atomizer 6 when
There can be good impetus.
