Description
One, technical field
The utility model relates to a kind of transmission oil supplying device, especially a kind of step-up gear planet lubrication oil supply device that is used for wind-power electricity generation.
Two, background technique
Domestic wind power generation speed increasing gear-box planetary pinion, bearing adopts splash lubrication or local oil jet lubrication mode substantially at present, do not have and force the oily device of profit continuously, the shortcoming of splash lubrication and local oil jet lubrication dual mode is: the planetary annular first half and the sun gear flank of tooth can not effectively lubricatings, noise is big when rotating, wearing and tearing between the gear are also big, shorten product working life, increase cost of electricity-generating.Be fixed on the lubricated oil-feed difficulty of planetary bearing on the planet axis, can not the effectively lubricating planetary bearing, grown running time, and planetary bearing is because of abrasion deformation, and the wind-powered electricity generation gear-box can not run well.Have only the replacing planetary bearing, can increase wind power cost.If a lubrication oil supply device is arranged, can carry out continuous pressure lubrication to tooth axle and bearing, just solved the problem of above-mentioned existence.
Three, model utility content
The purpose of this utility model provides a kind of wind-powered electricity generation gear-box planet lubrication oil supply device, and the position that solving present gear and bearing has in operation process can not get effective, continuous lubrication problem.
Concrete scheme of the present utility model is: mainly comprise supply ring, oil supplying sleeve, sun gear, planet carrier, shower nozzle, bearing, planet axis, planetary bearing, planetary pinion, ring gear, joint, casing.Wherein, planet carrier on casing, is fixed with planet axis by Bearing Installation on the planet carrier, is installed with two planetary bearings on planet axis.Be installed with planetary pinion on the described planetary bearing, this planetary pinion simultaneously with sun gear on gear and ring gear engagement.Key is: the elongation end that is fixed on the supply ring on the casing is to the oil transportation hole of planet carrier, and supply ring is connected with oil transportation hole in the planet carrier by oil supplying sleeve.Oil transportation hole one tunnel on the planet carrier passes to planet axis; Another road passes on the support arm of planet carrier, and the oil transportation hole on this planet carrier support arm is provided with the shower nozzle perpendicular to the oil transportation centerline hole.Oil supplying sleeve is solidly set on the elongation end of supply ring, and the oil transportation hole of this oil supplying sleeve and planet carrier is a Spielpassung.Oil transportation hole on the support arm of planet carrier is provided with three shower nozzles perpendicular to the oil transportation centerline hole.Supply ring is connected with oil inlet hole on the casing, and there is joint on the oil inlet hole top of this casing.
In the utility model supply ring is fixed on the casing, has avoided being fixed on the planet carrier because the centrifugal force that the supply ring rotation produces hinders the supply of lubricant oil.
Relative running between supply ring and the planet carrier in the utility model, the transition of middle employing oil supplying sleeve, oil supplying sleeve adopts interference to be connected with supply ring, adopt little Spielpassung between oil supplying sleeve and the planet carrier, so effective sealing lubricating oil also can solve owing to make relative friction between planet carrier that machining error causes and the supply ring.
Lubricant oil respectively to sun gear, ring gear and planetary bearing simultaneously carries out pressure lubrication by planet axis and planet carrier support arm by supply ring in the utility model after the planet carrier shunting.
According to the revolving property of planet carrier, the centrifugal force that the layout of lubrication channel makes the interior lubricant oil of passage produce on the planet carrier is consistent with oily flow path direction, helps passing through of lubricant oil in the utility model.
The utility model structure adopts from planet carrier rear end oil-feed mode, its spatial structure compactness, need not strict seal lubricant oil, easy to assembly, and can effectively utilize the rotary centrifugal force effect of planet carrier to make lubricated more reliable.
Adopt the advantage of such scheme to be: compact structure can continue, effective, stable give planetary pinion, planetary bearing, sun gear and ring gear provide lubricant oil, and can effectively utilize the rotary centrifugal force effect of planet carrier to make to lubricate more reliable.Since between gear and the gear and obtained between planetary bearing and the gear effectively continuing lubricated, reduced wearing and tearing each other, prolonged working life, reduced noise.
Four, description of drawings
