Description
Technical field
The present invention relates to a kind of gear-box, the planetary gear transmission mechanism of especially relevant wind power generation gear case.
Background technique
Wind turbine gearbox Operation Conditions is complicated, and driving torque is large, and gear produces a large amount of heats in engagement process, so in gear-box, each gear mesh lubrication and cooling requires very high.Rational lubricating system, can improve the mechanical efficiency of transmission system, more can significantly improve the working life of each gear.At present in the planetary gear train of wind power generation gear case, generally adopt pressure lubrication, to realize to planetary pinion and the gear ring jet lubrication oil of running by oil pipe fixing on casing and nozzle, because gear engagement position is changing always, cause actual lubrication efficiency low, and for the lubrication and cooling of the engagement place of planetary pinion and sun gear, due to the core position that is difficult in lubricant oil arrive, prior art is generally helpless.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, can to the engagement place of planetary pinion and sun gear and gear ring, be lubricated and cooling a kind of forced lubricating system for meshing of planetary system simultaneously.
The technological scheme that realizes above-mentioned purpose is: a kind of forced lubricating system for meshing of planetary system, comprise planet carrier, planetary pinion, sun gear and gear ring, planetary gear rotation is supported on planet carrier, planetary pinion and sun gear and gear ring engagement, in described planet carrier, have oil duct, the import of oil duct is located at the end face of axle journal of planet carrier or the end face on the axle journal side of planet carrier, on described oil duct, be communicated with the first nozzle and second nozzle, described the first nozzle is located at the inner side of column of planet carrier and the outlet of the first nozzle towards the engagement place of planetary pinion and sun gear, described second nozzle is located at the outside of column of planet carrier and the outlet of second nozzle towards gear ring.
Described planet carrier has three columns, and the inner side of each column is all communicated with first nozzle, and three the first nozzles are 120 ° of layouts; The outside of each column is all communicated with a second nozzle, and three second nozzles are 120 ° of layouts.
Described the first nozzle and second nozzle all adopt fan nozzle.
Adopt after the structure of technique scheme, owing to having oil duct in planet carrier, the import of oil duct is located at the end face of the axle journal of planet carrier, on oil duct, be communicated with the first nozzle and second nozzle, the first nozzle is located at the inner side of column of planet carrier and the outlet of the first nozzle towards the engagement place of planetary pinion and sun gear, and second nozzle is located at the outside of column of planet carrier and the outlet of second nozzle towards gear ring.Therefore the first nozzle can be lubricated with cooling the engagement place of planetary pinion and sun gear all the time, and when planet carrier rotates, second nozzle is realized the circulating lubrication to whole gear ring.Be that the present invention can be lubricated with cooling the engagement place of planetary pinion and sun gear and gear ring simultaneously, can effectively reduce engagement temperature, good cooling results; Because planet carrier is rotary component, oil supplying device is generally connected with static casing, in order to make lasting arrival the first nozzle and the second nozzle of cold oil energy, therefore the import of oil duct need to be set at the end face of axle journal of planet carrier or the end face on the axle journal side of planet carrier, rational in infrastructure, be convenient to manufacturing.

Embodiment
The present invention is further detailed explanation for the embodiment who provides below in conjunction with accompanying drawing.
As Fig. 1, 2, 3, shown in 5, a kind of forced lubricating system for meshing of planetary system, comprise planet carrier 1, planetary pinion 2, sun gear 3 and gear ring 4, planetary pinion 2 is rotatably supported on planet carrier 1, planetary pinion 2 and sun gear 3 and gear ring 4 engagements, in described planet carrier 1, have oil duct 1-1, the import 1-2 of oil duct 1-1 is located at the end face of the axle journal 1-4 of planet carrier 1, on described oil duct 1-1, be communicated with the first nozzle 5 and second nozzle 6, described the first nozzle 5 be located at the inner side of column 1-3 of planet carrier 1 and the outlet of the first nozzle 5 towards planetary pinion 2 engagement place 7 with sun gear 3, described second nozzle 6 is located at the outside of column 1-3 of planet carrier 1 and the outlet of second nozzle 6 towards gear ring 4.
As shown in Figure 4, the import 1-2 of oil duct 1-1 also can be located at the end face 1-5 on the axle journal 1-4 side of planet carrier 1.
As shown in Fig. 1,3,5, described planet carrier 1 has three column 1-3, and the inner side of each column 1-3 is all communicated with 5, three the first nozzles 5 of first nozzle and is 120 ° of layouts; The outside of each column 1-3 is all communicated with 6, three second nozzles 6 of a second nozzle and is 120 ° of layouts.Like this, three planetary pinions 2 have respectively lubricating oil path alone, have improved lubrication and cooling effect, and three second nozzles 6, simultaneously to gear ring 4 oil spouts, have also improved the lubrication and cooling effect of gear ring 4 simultaneously.
As shown in Figure 1, described the first nozzle 5 and second nozzle 6 all adopt fan nozzle, preferably adopt the fan nozzle of capable of regulating nozzle diameter size.Can make like this cold oil can cover in a big way the flank of tooth, increase lubrication and cooling area.
As shown in Figure 1, when the present invention works, planet carrier 1 rotates, and spray simultaneously three engagement places of the first 5 pairs, nozzle planetary pinion 2 and sun gear 3, thereby realize the lubrication and cooling to three engagement places of planetary pinion 2 and sun gear 3; Meanwhile, the oil of second nozzle 6 ejections covers each tooth by the sense of rotation along planet carrier 1 successively to gear ring 4, thereby realizes the circulating lubrication to gear ring 4.By adjusting the caliber size of the first nozzle 5 and second nozzle 6, realize the control of opposing jet amount, make cooling effect everywhere reach designing requirement simultaneously.
