Description
Technical field
The utility model relates to a kind of gear-box, particularly a kind of speed-increasing gearbox of wind driven generator.
Background technique
Existing speed-increasing gearbox of wind driven generator mainly comprises casing, planetary gear train, transition gear driving mechanism and output gear shaft.Planetary gear train is made up of input planet carrier, sun gear, planet wheel and ring gear.The transition gear driving mechanism is made of gearwheel, splined shaft, great transition gear, transition gear axle.Gearwheel is connected by splined shaft with the end of planetary gear train sun gear, and gearwheel is installed on the splined shaft, and the small offence on gearwheel and the transition gear axle is crossed gear engagement, small gear on the output gear shaft and the great transition gear engagement that is arranged on the transition gear axle.Transition gear driving mechanism in the existing speed-increasing gearbox of wind driven generator and the large and small gear on the output gear shaft are helical gear, this mainly is relatively poor in order to overcome spur gear transmission stability in transmission process, be easy to generate bigger impact, vibrating noise, and the contact stress that reduces the flank of tooth, the bearing capacity of the raising gear teeth.But, owing to helical gear flank of tooth Line of contact is and the uneven oblique line of axis, thereby when transmission, can produce an axial thrust load, the deformation effect transmission quality that this causes casing on the one hand influences transmission efficiency on the other hand.
The model utility content
The technical problems to be solved in the utility model provides a kind of speed-increasing gearbox of wind driven generator, and it is the transmission efficiency height not only, and the casing phenomenon that can not deform.
For solving the problems of the technologies described above, a kind of speed-increasing gearbox of wind driven generator of the utility model, it contains casing, planetary gear train, transition gear driving mechanism and output gear shaft, planetary gear train is by the input planet carrier, sun gear, planet wheel and ring gear are formed, ring gear is arranged on the interior front portion of casing, planet wheel is arranged on the bearing pin of input planet carrier periphery by bearing, the input end of input planet carrier passes the front end of casing, remaining part by Bearing Installation in the interior front portion of casing and be positioned at ring gear, planet wheel while and ring gear, the sun gear engagement, the transition gear driving mechanism is arranged on the interior rear portion of casing, the transition gear driving mechanism is by gearwheel, splined shaft, the great transition gear, the transition gear axle constitutes, gearwheel is connected by splined shaft with the end of planetary gear train sun gear, gearwheel is installed on the splined shaft, small offence on gearwheel and the transition gear axle is crossed gear engagement, the output terminal of output gear shaft passes the rear end of casing, remaining part is arranged on the interior rear portion of casing, small gear on the output gear shaft and the great transition gear engagement that is arranged on the transition gear axle, the gearwheel of described transition gear driving mechanism, little transition gear on great transition gear and the transition gear axle and the small gear on the output gear shaft are herringbone gear.
Because little transition gear on gearwheel, great transition gear and the transition gear axle of transition gear driving mechanism and the small gear on the output gear shaft are herringbone gear, and herringbone gear about two toothrows fully the symmetry, the axial thrust load that both sides are produced is cancelled each other, this has eliminated on the one hand that helical gear in the prior art produces in transmission process that axial thrust load causes box deformation and the generation that influences the transmission quality phenomenon has also improved transmission efficiency on the other hand.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
1. input planet carriers among the figure, 2. sun gear, 3. casing, 4. ring gear, 5. great transition gear, 6. small gear, 7. output gear shaft, 8. little transition gear, 9. transition gear axle, 10. splined shaft, 11. gearwheels, 12. bearings, 13. bearing pins, 14. planet wheels.
Embodiment
In the accompanying drawing, a kind of speed-increasing gearbox of wind driven generator of the utility model contains casing 3, planetary gear train, transition gear driving mechanism and output gear shaft 7.Planetary gear train is made up of input planet carrier 1, sun gear 2, planet wheel 14 and ring gear 4.Ring gear 4 is arranged on the interior front portion of casing 3, and star-wheel 14 is arranged on the bearing pin 13 of input planet carrier 1 periphery by bearing 12.Present embodiment is arranged on three uniform bearing pins 13 of input planet carrier 1 periphery by three bearings 13 respectively by three planet wheels 14.In the interior front portion of casing 3 and be positioned at ring gear 4, planet wheel 14 simultaneously and ring gear 4, sun gear 2 engagements by Bearing Installation for the front end, remaining part that the input end of input planet carrier 1 passes casing 3.The transition gear driving mechanism is arranged on the interior rear portion of casing 3, and the transition gear driving mechanism is made of gearwheel 11, splined shaft 10, great transition gear 5, transition gear axle 9.Gearwheel 11 is connected by splined shaft 10 with the end of planetary gear train sun gear 2, gearwheel 11 is installed on the splined shaft 10, little transition gear 8 engagements on gearwheel 11 and the transition gear axle 9, the output terminal of output gear shaft 7 passes the rear end of casing 3, remaining part is arranged on the interior rear portion of casing 3, small gear 6 on the output gear shaft 7 and great transition gear 5 engagements that are arranged on the transition gear axle 9.Little transition gear 8 on the gearwheel 11 of transition gear driving mechanism, great transition gear 5 and the transition gear axle 9 and the small gear 6 on the output gear shaft 7 are herringbone gear.Because the axial thrust load that the complete symmetry of two toothrows produces both sides about herringbone gear is cancelled each other, this has eliminated fully that helical gear in the prior art produces in transmission process that axial thrust load causes casing 3 distortion and the generation that influence the transmission quality phenomenon, and the while has also been improved transmission efficiency.
