Description
Technical field
The utility model is related to a kind of sealing structure of sound oil duct transition docking, and especially one kind is provided by force for planet carrier
The sealing structure of lubricant passage way processed.
Background technology
In wind-driven generator, gear-box is the critical component of wind-driven generator, and wherein lubricant passage way is most important again
Design link.It is well known that oil circuit is divided into outside oil circuit and internal oil passages.Outside oil circuit mainly includes flexible pipe and steel pipe, interior
Portion's oil circuit is divided into steel pipe and inside parts pipeline.In design, it is contemplated that the design of outside oil circuit will bring potential oil leak
Risk, safeguard inconvenience etc., therefore the Main way that outside oil circuit is following wind turbine gearbox design is replaced using internal oil passages.
But internal oil passages design must solve a problem:How by the lubricating oil in the static asphalt channel or pipeline on casing
It is transitioned into dynamic gear, on planet carrier, is that planetary gear or bearing etc. provide lubrication, so that the problem of solving static and dynamic sealing,
Current solution is that distribution ring is configured in planet carrier, is docked quiet dynamic part transition by distribution ring.
The part that permeability, oil leakage phenomenon can result in the need for lubrication cannot get enough lubricating oil and be lubricated and cool down, this
It would potentially result in bearing and gear lack lubricating oil and produces high temperature, and then produce the failure modes such as gluing due to quiet dynamic part
It is rigid structure, in order to prevent permeability, oil leakage phenomenon, common design is to use copper slip ring, is produced mutual
The part of motion respectively installs a copper ring, the tolerance fit of copper ring and gap each other is then controlled again, to solve sound
The problem of transition and sealing is lubricated, this mode generally requires the dimensional tolerance of strict control part and the deformation of part, no
Can then occur copper ring abrasion and seal failure.In addition, from angle of assembling, using the design of copper slip ring, being needed during assembling
Ensure the centring property between two copper rings using relevant tool, it is to avoid scuffing and abrasion between copper ring.It can be seen that, above-mentioned measure
Higher harsher requirement is proposed to machining accuracy and assembling index.How to reduce machining accuracy, simplify assembly technology and
Can improve rigid element be association of activity and inertia portion sealing effectiveness be this area top concern problem.
Utility model content
The purpose of this utility model is, for current rigid structure static and dynamic sealing problems faced, and prevents seepage
Solution need to propose the practical problem of higher harsher requirement to machining accuracy and assembling index that there is provided a kind of new
The sealing structure that forced feed lubrication oil circuit is provided for planet carrier.
What the purpose of this utility model was realized in：A kind of sealing structure that forced feed lubrication oil circuit is provided for planet carrier,
Including box body oil duct, planet carrier oil duct and the distribution ring between them, it is characterised in that：The butt end of described box body oil duct
Mouth is provided with nesting, and nested center is provided with hole corresponding with box body oil duct, distribution ring ring shaped oil passage both sides corresponding with box body oil duct
Provided with symmetrical annular groove, the position position of annular groove corresponds in the nested coverage of box body oil duct craft port, is provided with annular groove
The metal of matching folds ring.
In the utility model：The surface that described nesting and metal fold ring is covered with cure process layer.
In the utility model：In distribution ring location and installation planet carrier, the annular in the hole and distribution ring in nested center
Oil duct is docked, and box body oil duct is linked up by nesting by distribution ring and planet carrier oil duct.
The utility model has the advantage of：Because the utility model is located at metal in sound docking oil duct both sides, to fold ring close
Envelope, and the folded ring requirement on machining accuracy of metal is relatively low, it is only necessary to the dimensional tolerance of distribution ring annular groove is controlled, to related mating parts
Other sizes and form and position tolerance without it is special be strict with.After installing, folding ring in metal can be with automatic centering, it is ensured that point
With ring and nested synchronous naturally centering.Because the surface that nested and metal folds ring is covered with cure process layer, its anti-wear performance is bright
It is aobvious to be higher than traditional copper ring.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the partial enlarged drawing of I in Fig. 1.
In figure：1st, box body oil duct, 2, planet carrier oil duct, 3, distribution ring, 4, nested, 5, hole, 6, ring shaped oil passage, 7, metal folds
Ring, 8, planet carrier.
Embodiment
The nonrestrictive concrete structure for disclosing the utility model embodiment of accompanying drawing is new to this practicality below in conjunction with the accompanying drawings
Type is further described.
From Fig. 1 and Fig. 2, the utility model includes box body oil duct 1, planet carrier oil duct 2 and point between them
With ring 3, wherein：The craft port of described box body oil duct 1 is provided with hole corresponding with box body oil duct provided with nesting 4, the center of nesting 4
5, the both sides of ring shaped oil passage 6 corresponding with box body oil duct 1 of distribution ring 3 are provided with symmetrical annular groove, and the position position of annular groove corresponds to casing
In the coverage of the craft port nesting 4 of oil duct 1, the metal provided with matching in annular groove folds ring 7.
In the present embodiment：In the location and installation planet carrier 8 of distribution ring 3, hole 5 and the ring in distribution ring 3 in the center of nesting 4
Shape oil duct 6 is docked, and box body oil duct 1 is linked up by nesting 4 by distribution ring 3 with planet carrier oil duct 2.
During specific implementation：The surface that described nesting 4 and metal fold ring 7 is covered with cure process layer.
In actual use, metal, which folds ring 7, can prevent lubricating oil by the both sides seepage of ring shaped oil passage 6 in distribution ring 3.
