Axle.
First gear wheel 11 is driven by input shaft.First pinion shaft 21 at least two, i.e. the first pinion shaft 21
Number is more than or equal to two.All of first pinion shaft 21 is all engaged with the first gear wheel 11, and all of first little gear
Axle 21 is distributed around the circumferencial direction of the first gear wheel 11.Multiple first pinion shafts 21 engage reality with the first gear wheel 11
The shunting of power is showed.Also, the first pinion shaft 21 is engaged for external tooth with the first gear wheel 11, is not limited by space, can
With shape and the number of teeth by changing the first gear wheel 11 and the first pinion shaft 21, larger gearratio is obtained.
Second gear wheel 12 is respectively connected with each first pinion shaft 21.The second gear wheel of each two 12 and one
Individual second pinion shaft 22 is engaged.If the number of the second gear wheel 12 is even number, then be just the second gear wheel of each two
12 are engaged with second pinion shaft 22；If the number of the second gear wheel 12 is odd number, that can remain next second canine tooth
Wheel 12, remaining second gear wheel 12 is individually engaged with second pinion shaft 22.It is obvious that transmission power is in the second little tooth
Interflow for the first time is achieved at wheel shaft 22.A third-largest gear 12 is respectively connected with each second pinion shaft 22, owns
The third-largest gear 12 all engage with central pinion 3, i.e., achieve second of transmission power conjunction at central pinion 3
Stream.If it will be appreciated by persons skilled in the art that the number of the second gear wheel 12 is only two, then the two are second largest
Gear 12 is meshed with second pinion shaft 22, and second pinion shaft 22 is directly engaged with central pinion 3.Finally,
Central pinion 3 drives output shaft rotation, and high rotating speed is exported.
In one specific embodiment of the utility model, the first pinion shaft 21 is four couples, i.e., eight.Due to each first
Second gear wheel 12 is connected with pinion shaft 21, then the second gear wheel 12 is also four pairs.

Two oppositely oriented the second gear wheels 12.In addition, the second pinion shaft 22 in will be above-mentioned is preferably double helical tooth pinion shaft,
So, double helical tooth pinion shaft is simultaneously identical with helical angle, but two oppositely oriented the second gear wheels 12 are engaged, then, the
The axial force of two the second gear wheels 12 that two pinion axle 22 is born is equal in magnitude, in opposite direction, therefore cancels out each other, so
The load of bearing is just alleviated, extends the service life of bearing.In addition, double helical tooth pinion shaft can pass through left and right play,
Automatically adjust the load inhomogeneities that many power dividings of the second gear wheel bring.
Further, the second pinion shaft 22 is preferably the double helical tooth pinion shaft nothing withdrawing slot type.Can so make
The structure of whole device is compacter, is driven more steady.
In one specific embodiment of the utility model, each second gear wheel 12 is first little with one by the first spline
Gear shaft 21 connects.The large carrying capacity of spline, can make the second gear wheel 12 and the first pinion shaft 21 with good right
Neutrality, so that it is guaranteed that the steady transmission of device.
In one specific embodiment of the utility model, each the third-largest gear 13 is second little with one by the second spline
Gear shaft 22 connects.Second spline can make the third-largest gear 13 and the second pinion shaft 22 with good centering.
In one specific embodiment of the utility model, also include the fourth-largest gear 14 and third pinion axle 23.The fourth-largest
Gear 14 is coaxially connected with central pinion 3, and the two is coaxial in other words.Third pinion axle 23 is mutually nibbled with the fourth-largest gear 14
Close, the third pinion axle 23 is output shaft.The purpose for so arranging is to facilitate the extraction of output shaft, and the fourth-largest tooth
Wheel 14 further increases output speed with engaging for third pinion axle 23.
The invention also discloses a kind of gear box device, including gear-box and the multi-shunting fixed shaft in gear-box
Transmission device, the multi-shunting fixed shaft transmission device are any one multi-shunting fixed shaft transmission device above-mentioned.Above-mentioned multi-shunting fixed shaft
Transmission device has the effect above, and the gear box device with above-mentioned multi-shunting fixed shaft transmission device equally has the effect above,
Therefore repeat no more herein.
Further, in one specific embodiment of the utility model, gear-box is formed by becoming the multiple layer combination being distributed up and down.
For being detachably connected between adjacent two-layer.The faying face of adjacent two-layer is die joint, the first pinion shaft of each two 21
On a die joint.If certain first pinion shaft 21 occurs in that fault, then can will divide accordingly in cabin
Type face is taken apart, individually keeps in repair the pinion shaft 21 for breaking down, and keeps in repair without tower under whole machine, so as to reduce maintenance cost.
In one specific embodiment of the utility model, the first pinion shaft 21 is eight, and gear-box is distributed up and down by becoming
Five layers combine, and this five layers define into four die joints being distributed up and down, and the first pinion shaft of each two 21 is located at one
On die joint.In five layers, if regulation from top to bottom be respectively ground floor 41, the second layer 42, third layer 43, the 4th layer 44 with
And layer 5 45, in four die joints, if regulation be followed successively by from top to bottom the first die joint 51, the second die joint 52, the
Three parting line 53 and tetrad segregation types face 54, then, if the first pinion shaft 21 in the first die joint 51 will be keeped in repair,
So just ground floor 41 is dismantled down, two the first pinion shafts 21 will be exposed；If keeped in repair positioned at the second die joint
The first pinion shaft 21 in 52, then just ground floor 41 and the second layer 42 are pulled down together；If keeped in repair positioned at the 4th point
Layer 5 45 is just pulled down by the first pinion shaft 21 in type face 54；If keeping in repair first in three parting line 53
Layer 5 45 and the 4th layer 44 are just pulled down by pinion shaft 21 together.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Multiple modifications to these embodiments will be apparent for those skilled in the art, be determined herein
The General Principle of justice can be realized in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
