Description
Technical field
The utility model relates to the gear-box lubrication technical field, relates in particular to a kind of planetary gear train lubrication system.The utility model also relates to a kind of wind-powered electricity generation gear-box with above-mentioned planetary gear train lubrication system.
Background technique
Normal planetary gear device and the planet-cylindrical gears device of adopting in the wind-powered electricity generation gear-box; Wherein, Planetary gear device comprises planet wheel, planet axis, planet carrier and planet wheel bearing etc., and planet wheel bearing whether can the sufficient lubrication meeting directly influences the working life of gear-box.
In the prior art, adopt a cover planetary gear train lubrication system usually, the lubricant oil of gear-box is introduced planetary gear train planet wheel bearing is lubricated, common planetary gear train lubrication system mainly contains following two kinds of schemes.
First kind of scheme: oily distribution loop overcoat wear ring, and wear ring is overlapping planet carrier outward again, and wherein oily distribution loop and casing are static relatively, and wear ring rotates with planet carrier together.Lubricant oil gets into oily distribution loop from casing, radially passes oily distribution loop and wear ring and arrives planet carrier, through planet carrier oil circuit and the lubricated planet wheel bearing of planet axis oil circuit.In the real-world operation process, following problem appears in this planetary gear train lubrication system easily:
In the gear-box operation process, inner body can produce bigger distortion with temperature variation.The part deformation amount is different with temperature variation, so there is big uncertainty in the gap between wear ring inner headed face and the oily distribution loop periphery, thereby causes the lubricating status of planet wheel bearing unstable.
1) if preset clearance is too big between gear-box when assembling wear ring inner headed face and the oily distribution loop periphery; When temperature was low, oily distribution loop external diameter reduced, and the wear ring internal diameter increases; The gap further increases between the two; Thereby make lubricant oil oil pressure loss too big, even lubricant oil all flow out from the gap, can not the effectively lubricating planet wheel bearing.
2) if preset clearance is too little between gear-box when assembling wear ring inner headed face and the oily distribution loop periphery; After temperature raises; Oil distribution loop external diameter increases; So and wear ring occurs wear ring possibly and becomes " stuck " phenomenon that interference is connected with oily distribution loop, initiating failure because the outside is being overlapped the planet carrier internal diameter and reduced.
Second kind of scheme: the direct and planet carrier end face applying of oily distribution loop, lubricant oil gets into oily distribution loop from casing, directly gets into planet carrier from the planet carrier end face then.Because oily distribution loop and casing are static relatively; So planet carrier end face and the direct contact friction of oily distribution loop; In operation process; Increasing because of wearing clearance between planet carrier end face and the oily distribution loop, the pressure loss of lubricant oil also becomes greatly, and can cause does not have enough lubricant oil that planet wheel bearing is lubricated yet.
Therefore, how to develop a kind of planetary gear train lubrication system, with the sufficient lubrication that guarantees planet wheel bearing and avoid planet carrier and oily distribution loop appearance " stuck " phenomenon, become the technical barrier of related domain.
