Abstract
The invention discloses a kind of step-up gear, including: planet pinion group；Planet pinion group includes: power end planetary gearsets and speedup planetary gearsets；Power end planetary gearsets and the power input shaft engaged transmission of gear-box, power end planetary gearsets is coaxially disposed with speedup planetary gearsets, on the central gear position of speedup planetary gearsets, output shaft is set, makes the output shaft transmission of speedup planetary gearsets driven gear case.Step-up gear in the present invention, by arranging output shaft on the central gear position of speedup planetary gearsets, central gear be by the central gear in speedup planetary gearsets around the engagement of three planet pinions drive, reach the purpose of the output shaft transmission of speedup planetary gearsets driven gear case.Because central gear therein need not bearings, it is possible to realize higher rotary speed, thus ensure the output speed of step-up gear.
Description
Technical field
The present invention relates to mechanical driving device technical field, particularly relate to a kind of step-up gear.
Background technology
The output shaft of existing step-up gear typically requires use bearings, uses bearings, does not reaches gear high
The purpose that speed rotates, the speed of output shaft will be affected, thus limit the output speed of speed increasing gear.
Summary of the invention
For solving in prior art, the output shaft that step-up gear exists uses bearings, causes output speed limited
Technical problem, technical scheme is as follows:
Step-up gear in the present invention, including: planet pinion group；Described planet pinion group includes: power
End planetary gearsets and speedup planetary gearsets；Described power end planetary gearsets engages with the power input shaft of described gear-box
Transmission, described power end planetary gearsets is coaxially disposed with described speedup planetary gearsets, and described speedup planetary gearsets is too
On sun gear position, output shaft is set, makes described speedup planetary gearsets drive the output shaft transmission of described gear-box.
In a preferred embodiment, the gear in described power end planetary gearsets is spur gear.
In a preferred embodiment, the gear in described speedup planetary gearsets is herringbone bear.
In a preferred embodiment, around the central gear in described power end planetary gearsets and central gear
The gear ratio of planet pinion be 5:2；Central gear in described speedup planetary gearsets and the planet around central gear
The gear ratio of little gear is 4:1.
In a preferred embodiment, the planet in described power end planetary gearsets and speedup planetary gearsets is little
Gear is three.
Step-up gear in the present invention, compared with prior art, it has the beneficial effect that
Step-up gear in the present invention, by arranging output shaft on the central gear position of speedup planetary gearsets,
Central gear be by the central gear in speedup planetary gearsets around the engagement of three planet pinions drive, reach to increase
The purpose of the output shaft transmission of speed planetary gear group driven gear case.Because central gear therein need not bearings, energy
The rotary speed that enough realizations are higher, thus ensure the output speed of step-up gear.
Power end planetary gearsets and speedup planetary gearsets are equivalent to two speeders engaging each other connection, the most in fact
Show two-stage speedup, and owing to power end planetary gearsets is coaxially disposed with described speedup planetary gearsets, installed and used non-
Often convenience, and gear-box volume will diminish, and will not take larger space.
Gear in power end planetary gearsets is spur gear, and the gear in speedup planetary gearsets is herringbone bear；Adopt
By the combination speedup form of double helical tooth and straight-tooth, not having any axial force, stability strengthens.
Accompanying drawing explanation
Fig. 1 is the structural representation of step-up gear in the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described.Based on this
Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, step-up gear, including: planet pinion group；Planet pinion group includes: power end row
Star gear train and speedup planetary gearsets；Power end planetary gearsets and power input shaft 5 engaged transmission of gear-box, power end
Planetary gearsets is coaxially disposed with speedup planetary gearsets, and the central gear position of speedup planetary gearsets arranges output shaft 1,
Make output shaft 1 transmission of speedup planetary gearsets driven gear case.Gear in power end planetary gearsets is spur gear.Speedup
Gear in planetary gearsets is herringbone bear.
Wherein power end planetary gearsets includes power end central gear 3 and three little teeth of power end planet about
Wheel；Speedup planetary gearsets includes three speedup end planet pinions 2 around speedup central gear and central gear.Power end
Planet pinion is connected with speedup end planet pinion 2 by power transmission shaft 4.Central gear in power end planetary gearsets 3 with
The gear ratio of the planet pinion around central gear is 5:2；Central gear in speedup planetary gearsets and central gear week
The gear ratio of the planet pinion 2 enclosed is 4:1.Concrete gear ratio determines according to service condition, it is achieved defeated from gear-box
Enter axle to two grades of speedups of gearbox output shaft.
The above, the only detailed description of the invention of the present invention, but protection scope of the present invention is not limited thereto, and any
Those familiar with the art, in the technical scope that the invention discloses, can readily occur in change or replace, should contain
Cover within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with described scope of the claims.
