Description
Technical field
The present invention relates to a kind of slip ring structure of portion's lubricant passage way of being association of activity and inertia, planet in especially a kind of wind power speed-increasing gearbox
The slip ring structure of lubricant passage way, belongs to machinery field between the planet carrier and cabinet of train.
Background technique
Wind-power electricity generation compared with traditional thermal power generation there is the free of contamination advantage that generates electricity to have compared with hydroelectric generation
Capital construction is at low cost, occupied area is small, the convenient advantage of maintenance, especially large-scale water-power plant, and storage reservoir is also easy to pair
Cause some potential safety problems in downstream.
In wind-driven generator, wind power speed-increasing gearbox is wherein critical component, wherein internal lubricating system strong influence wind
The runnability of electric gearbox.Internal lubricating system, which needs for oil liquid to be transported in revolving part from static part, goes, tradition
Solution have complicated structure.
Wherein slip ring is the common scheme of the current position lubricant passage way communication that solves to be association of activity and inertia, and this solution is being
The preferable copper alloy slip ring of one rigidity is fixed in rotation or static part, and utilizes the wherein several of copper alloy slip ring
Go rancid in a hole.This traditional infrastructure cost is high, and processing request is high, and crushing and oil damage are big, and occupy biggish axial space, this
The high torque density and compact of wind power speed-increasing gearbox are required to cause huge challenge, while pressure release, draining, interference friction etc. are asked
Topic also brings wind power speed-increasing gearbox very big global failure risk.In face of these problems, this field is badly in need of one kind and is not take up axial sky
Between, the new structure that structure is simple, easy to assembly and non-maintaining.
Summary of the invention
It is an object of the invention to: lubricant passage way tradition slip ring interior in current wind power speed-increasing gearbox there are aiming at the problem that, this
Invention provides a kind of novel slip-ring structure for portion's lubricant passage way of being association of activity and inertia in wind power speed-increasing gearbox.
The object of the present invention is achieved like this: a kind of slip ring knot for portion's lubricant passage way of being association of activity and inertia in wind power speed-increasing gearbox
Structure, cabinet and planet carrier including slip ring and containing oil leab, which is characterized in that slip ring is by inner ring slip ring and outer ring slip ring
The oil leab engaging portion of composition, cabinet and planet carrier is equipped with corresponding concentric slip ring mounting groove, wherein the side of inner ring slip ring
It being mounted on the slip ring mounting groove of cabinet by inner hole interference, the corresponding groove of the other side and planet carrier keeps uniform glade plane space,
Outer ring slip ring side is mounted on the slip ring mounting groove of planet carrier by outer circle interference, and the corresponding groove of the other side and cabinet keeps equal
Even glade plane space；Annular space between two slip rings is the annular transitional lubricating oil linked up between box body oil duct and planet carrier oil duct
Road.
In the present invention: inner ring slip ring is located in the mounting groove of cabinet by pin and plug, and outer ring slip ring passes through pin
Son is located on planet carrier with plug.
In the present invention, the inner ring slip ring and outer ring slip ring are the thin-walled rings of wear-resistant material production.
It is an advantage of the current invention that since cabinet and planet carrier spacing are very short, interior oil circuit slip ring structure of the invention can be with
Meet ultra-compact axial distance, to save the axial length of wind power speed-increasing gearbox.Since inner ring slip ring is the very big thin-walled of diameter
Ring will become ellipse during processing etc., the present invention is covered on the mounting groove of cabinet by inner hole interference baking, due to cabinet
Rigidity is very big, and thin-wall part inner ring slip ring can be forced to become round, to also keep on entire circle with planet carrier annular groove inner hole
Uniform glade plane space；The outer ring that same theory is also applied for thin-wall part outer ring slip ring, which is dried, to be covered on the mounting groove of planet carrier, together
When and cabinet mounting groove keep glade plane space.Slip ring keeps uniform glade plane space that can make to moisten with cabinet and planet carrier respectively
Lubricating oil leaks less, prevents slip ring interference friction, and extends thin-walled ring service life；Meanwhile a small amount of leakage also will form oil
Sealing, reduces the pressure loss of lubricating oil.Since Internal and external cycle is respectively positioned at by pin and plug pair of planet carrier and cabinet
It answers in slot, axial displacement occurs for the positioning end that can prevent the variation because of operating temperature from making Internal and external cycle slip ring.

Specific embodiment
Attached drawing is unrestricted to disclose specific embodiments of the present invention, makees with reference to the accompanying drawing to the present invention further
Description.
As seen from Figure 1, the present invention includes slip ring and cabinet 1 and planet carrier 4 containing oil leab, and slip ring is slided by inner ring
Ring 3 and outer ring slip ring 5 form, and the oil leab engaging portion of cabinet 1 and planet carrier 4 is equipped with corresponding concentric slip ring mounting groove,
In, the side of inner ring slip ring 3 is mounted on the slip ring mounting groove of cabinet 1 by inner hole interference, and the other side is corresponding with planet carrier 4
Slot keeps glade plane space, and slip ring 5 side in outer ring is mounted on the slip ring mounting groove of planet carrier 4 by outer circle interference, the other side with
The corresponding groove of cabinet 1 keeps glade plane space；Annular space between two slip rings be link up box body oil duct 7 and planet carrier oil duct 9 it
Between annular transitional lubricant passage way 8.
In the present embodiment: inner ring slip ring is located in the mounting groove of cabinet 1 by pin 2 and plug 6, outer ring slip ring 5
It is located on planet carrier 4 by pin 2 and plug 6.The inner ring slip ring 3 and the equal wear-resistant material of outer ring slip ring 5 make thin
Wall ring.
In use, the annular transitional lubricant passage way 8 formed between the 5 inner ring wall of cylindrical wall and outer ring slip ring of inner ring slip ring 3
Simultaneously and planet carrier oil duct 9 and box body oil duct 7 it is fully switched on；The lubricating oil of wind power speed-increasing gearbox flows into annular from box body oil duct 7
Transition lubricant passage way 8, then outflow enters planet carrier oil duct 9 from annular transitional lubricant passage way 8, to the planetary gear on planet carrier
It is lubricated with bearing etc..
