Description
Technical field
The utility model 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.In the planetary gear train of wind power generation gear case, generally adopt pressure lubrication at present, carry out pressure lubrication and cooling to the planetary pinion of running through oil pipe fixing on the casing.Existing planetary system outer gearing forced lubrication device adopts number of components more, and structure is complicated, inconvenient machining.
Summary of the invention
The purpose of the utility model is to provide a kind of compact structure, is convenient to process, can lubricant oil effectively be delivered to the planetary system outer gearing forced lubrication device of planetary pinion mesh regional.
The technological scheme that realizes above-mentioned purpose is: a kind of planetary system outer gearing forced lubrication device, comprise casing, gear ring, planet carrier, planetary pinion and sun gear, and wherein the planet carrier rotational support is on casing; The planetary pinion rotational support is on planet carrier; Planetary pinion and sun gear and gear ring engagement, said planet carrier is provided with oilhole, and the import of oilhole is positioned on the side relative with inner side surface casing planet carrier; The outlet of oilhole is towards the flank of tooth of sun gear; Have the oiling road on the said casing and be provided with nozzle, the oiling road communicates with nozzle, when the relative casing of planet carrier rotates; The outlet of nozzle can be aimed at the import of the oilhole of planet carrier, thus oil spout in oilhole.
The import of said oilhole is circumferential arc opening.
Said oilhole is an inclined hole, the outlet of oilhole than the import of oilhole more near the center of planet carrier.
Said planet carrier is equipped with several planetary pinions, and the quantity of oilhole is consistent with planetary quantity, and each planetary pinion is furnished with an oilhole fuel feeding.
After adopting the structure of technique scheme, because planet carrier is provided with oilhole, the import of oilhole is positioned on the side relative with inner side surface casing planet carrier; The outlet of oilhole has the oiling road and is provided with nozzle towards the flank of tooth of sun gear on the casing, the oiling road communicates with nozzle; When the relative casing of planet carrier rotates; The outlet of nozzle can be aimed at the import of the oilhole of planet carrier, thus oil spout in oilhole, therefore; Lubricant oil can effectively arrive the planetary pinion mesh regional through oilhole, and planetary pinion and sun gear are lubricated and cool off; In addition, the utility model also has the characteristics of compact structure, is particularly useful for the less planetary gear train structure of size; Amount of parts is less, and oilhole can directly cast out on planet carrier, need on planet carrier, not process boring, therefore is convenient to processing; Nozzle is located on the casing, is convenient to assembling, dismounting.

Embodiment
The embodiment who provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.
Like Fig. 1,2,3, shown in 4, a kind of planetary system outer gearing forced lubrication device comprises casing 5, gear ring 4, planet carrier 1, planetary pinion 3 and sun gear 2; Wherein planet carrier 1 rotational support is on casing 5, and planetary pinion 3 rotational support are on planet carrier 1, and planetary pinion 3 meshes with sun gear 2 and gear ring 4; Said planet carrier 1 is provided with oilhole 1-1; The import 1-2 of oilhole 1-1 is positioned on the side 1-3 relative with inner side surface 5-1 casing 5 planet carrier 1, and the outlet 1-5 of oilhole 1-1 has oiling road 5-2 and is provided with nozzle 6 towards the flank of tooth of sun gear 2 on the said casing 5; Oiling road 5-2 communicates with nozzle 6; When planet carrier 1 relative casing 5 rotated, the outlet of nozzle 6 can be aimed at the import 1-2 of the oilhole 1-1 of planet carrier 1, thus oil spout in oilhole 1-1.
Like Fig. 2, shown in 4, the import 1-2 of said oilhole 1-1 is circumferential arc opening.Like this, be convenient to planet carrier 1 and when rotating, can as often as possible be received into oil from nozzle 6.
Like Fig. 1,3, shown in 4, said oilhole 1-1 is an inclined hole, the outlet 1-5 of oilhole 1-1 than the import 1-2 of oilhole 1-1 more near the center of planet carrier 1.Like this, be convenient to the mesh regional that the interior oil of oilhole 1-1 flows to planetary pinion and sun gear.
Like Fig. 1,2, shown in 4, said planet carrier 1 is equipped with several planetary pinions 3, and the quantity of oilhole 1-1 is consistent with the quantity of planetary pinion 3, and each planetary pinion 3 is furnished with an oilhole 1-1 fuel feeding.Like this, each planetary pinion 3 has lubricating oil path alone respectively, improves lubricated and cooling effect.
As shown in Figure 1, because planetary pinion 3 is contained on the planet carrier 1, so planetary pinion 3 is changeless with sun gear 2 mesh regionals with respect to planet carrier 1, so the oilhole 1-1 on the planet carrier 1 also is changeless towards mesh regional.When the oiling road 5-2 on the casing 5 continued fuel feeding, nozzle 6 sprayed to oilhole 1-1 with the lubricant oil of cooling, arrived mesh regional through oilhole 1-1, thereby reached effect lubricated and the cooling gear.
