Description
Technical field
The present invention relates to a kind of gear-box, the planetary pinion drive mechanism of especially relevant wind power generation gear case.
Background technique
Wind-powered electricity generation gear-box running operating mode is complicated, and driving torque is big, and gear produces great amount of heat in engagement process, so the lubricated and cooling of each gear mesh requires very high in the gear-box.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 adopting pressure lubrication, is to realize to the planetary pinion and the gear ring jet lubrication oil of running through oil pipe fixing on the casing and nozzle, because gear engagement position is changing always; Cause actual lubricated cooling effectiveness low; And for the lubricated and cooling of the engagement place of planetary pinion and sun gear, owing to be in the core position that lubricant oil is difficult to arrive, existing technology is generally powerless.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, a kind of planetary system engagement forced lubricating system of can be simultaneously the engagement place and the gear ring of planetary pinion and sun gear being lubricated and cooling off.
The technological scheme that realizes above-mentioned purpose is: a kind of planetary system engagement forced lubricating system; Comprise planet carrier, planetary pinion, sun gear and gear ring; The planetary pinion rotational support is on planet carrier; Planetary pinion and sun gear and gear ring engagement; Have oil duct in the said planet carrier, the import of oil duct is located at the end face on axle journal next door of end face or planet carrier of the axle journal of planet carrier, is communicated with first nozzle and second nozzle on the said oil duct; Said first nozzle is located at the outlet of inboard and first nozzle of column of planet carrier towards the engagement place of planetary pinion and sun gear, and said second nozzle is located at the outlet of the outside and second nozzle of column of planet carrier towards gear ring.
Said planet carrier has three columns, and the inboard of each column all is communicated with one first nozzle, and three first nozzles are 120 ° of layouts; The outside of each column all is communicated with one second nozzle, and three second nozzles are 120 ° of layouts.
Said first nozzle and second nozzle all adopt fan nozzle.
After adopting the structure of technique scheme; Owing to have oil duct in the planet carrier; The import of oil duct is located at the end face of the axle journal of planet carrier; Be communicated with first nozzle and second nozzle on the oil duct, first nozzle is located at the outlet of inboard and first nozzle of column of planet carrier towards the engagement place of planetary pinion and sun gear, and second nozzle is located at the outlet of the outside and second nozzle of column of planet carrier towards gear ring.Therefore first nozzle can be lubricated the engagement place of planetary pinion and sun gear and cool off all the time, and when planet carrier rotated, second nozzle was realized the circulating lubrication to whole gear ring.Be that the present invention can be simultaneously be lubricated and cools off the engagement place of planetary pinion and sun gear and gear ring, can effectively reduce engagement temperature, good cooling results; Because planet carrier is a rotary component; Oil supplying device generally is connected with static casing; For arrival first nozzle and second nozzle that cold oil can be continued; Therefore the import of oil duct need be set at the end face on the axle journal next door of the end face of the axle journal of planet carrier or planet carrier, rational in infrastructure, be convenient to manufacturing.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing does further detailed explanation to the present invention.
Like Fig. 1,2,3, shown in 5; A kind of planetary system engagement forced lubricating system; Comprise planet carrier 1, planetary pinion 2, sun gear 3 and gear ring 4; Planetary pinion 2 rotational support are on planet carrier 1, and planetary pinion 2 and sun gear 3 and gear ring 4 engagements have oil duct 1-1 in the said planet carrier 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; Be communicated with first nozzle 5 and second nozzle 6 on the said oil duct 1-1, said first nozzle 5 is located at the outlet of inboard and first nozzle 5 of column 1-3 of planet carrier 1 towards the engagement place 7 of planetary pinion 2 with sun gear 3, and said second nozzle 6 is located at the outlet of the outside and second nozzle 6 of column 1-3 of planet carrier 1 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 next door of planet carrier 1.
Like Fig. 1,3, shown in 5, said planet carrier 1 has three column 1-3, and the inboard of each column 1-3 all is communicated with 5, three first nozzles 5 of one first nozzle and is 120 ° of layouts; The outside of each column 1-3 all is communicated with 6, three second nozzles 6 of one second nozzle and is 120 ° of layouts.Like this, three planetary pinions 2 have lubricating oil path alone respectively, have improved lubricated and cooling effect, and three second nozzles 6 have also improved the lubricated and cooling effect of gear ring 4 simultaneously to gear ring 4 oil spouts simultaneously.
As shown in Figure 1, said first nozzle 5 and second nozzle 6 all adopt fan nozzle, preferably adopt the fan nozzle that can adjust the nozzle diameter size.Can make cold oil can cover the flank of tooth in a big way like this, increase lubricated and film-cooled heat.
As shown in Figure 1, when the present invention worked, planet carrier 1 rotated, and spray simultaneously three engagement places of 5 pairs of planetary pinions of first nozzle 2 and sun gear 3, thereby realized the lubricated and cooling to three engagement places of planetary pinion 2 and sun gear 3; Simultaneously, the oil of second nozzle, 6 ejections will cover each tooth to gear ring 4 successively along the sense of rotation of planet carrier 1, thereby realize the circulating lubrication to gear ring 4.Through adjusting the caliber size of first nozzle 5 and second nozzle 6, realize the control of opposing jet amount, make cooling effect everywhere reach designing requirement simultaneously.
