The external splines matched on axle, two output gears and with internal spline.
Further, described clutch is two clutches.
Use said structure: multiple gear i.e. can be set on axle, and pass through what clutch selection was connected with axle key
Gear, from without the quantity increasing axle so that more compact structure, and can obtain the combination of multiple speed ratio.
As it has been described above, the method have the advantages that
1, power shaft is arranged with the space of output shaft, makes the axis spacing of 2 output shafts less than power shaft and 2 output shafts
The sum of axis spacing, i.e. D3 ＜ D1+D2.Therefore gearbox designs is the compactest, beneficially the high-speed stable running of change speed gear box；
2, make the gear on power shaft, output shaft optionally be connected with axle key by clutch, can be combined out a plurality of
Power transmission path, thus obtain multiple different output speed ratio combination, with the need adapting to small lot, many dimension wires produce
Ask；
3, realize gear by clutch to engage with the selectivity of axle, when driving gear engagement transmission power, freely revolve
The gear turned can play the effect of synchronization, and therefore output shaft rotation is more steady.

Detailed description of the invention
By particular specific embodiment, embodiments of the present invention being described below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
Embodiment 1
Refer to Fig. 1 to Fig. 8.In order to describe the present invention in detail, next the present invention is illustrated: compact
Formula change speed gear box, including casing 6, is provided with 1 power shaft 1 and 2 output shafts 2,3 in casing 6.Power shaft 1 and the two of output shaft 2,3
End is all arranged on the sidewall of casing 6 by bearing.
Power shaft 1 is positioned in the middle part of casing 6,2 output shaft 2,3 symmetries be arranged on position on the lower, power shaft 1 both sides, i.e.
The axis of power shaft 1 and the axis of output shaft 2,3 are the most at grade.As in figure 2 it is shown, so arrange, 2 output shafts 2,3
Axis spacing D3 less than power shaft 1 and 2 output shaft 2,3 axis spacings and D1+D2 so that this apparatus structure more steps up
Gather.
Power shaft 1 is provided with 2 input gears, i.e. input gear Z1 and input gear Z2.Output shaft 3 on the left of power shaft
The output gear being provided with 2 of upper correspondence, i.e. output gear Z4 and output gear Z6；In like manner also have output gear Z3 and output gear
Wheel Z5.Wherein, output gear Z3 is identical with the output gear Z4 number of teeth, and output gear Z5 is identical with the output gear Z6 number of teeth.
In the present embodiment, input gear Z1, input gear Z2 are spindle rotationally arranged on power shaft 1 by bearing.?
Power shaft 1 is provided with clutch 4, and clutch 4 is two clutches, and this clutch 4 is positioned at input gear Z1 and input gear
Between Z2, clutch 4 is provided with internal spline 41, and power shaft 1 is provided with the external splines 11 corresponding with internal spline 41, equally, defeated
Enter and on gear Z1 and input gear Z2, also be provided with the external splines 5 corresponding with clutch 4.
So arrange, power shaft 1 can be selected to be exported by input gear Z1 or input gear Z2 by clutch 4.As
Shown in Fig. 4, when the external splines 5 on the internal spline 41 of clutch 4 and the external splines 11 of power shaft 1 and input gear Z1 connects
Time, drive output gear Z3, output gear Z4 to rotate by input gear Z1 when power shaft 1 rotates, thus obtain a kind of output
Speed ratio combines.Further, when output shaft 2,3 rotates, output gear Z5, output gear Z6 rotate simultaneously, and with input gear Z2
Engagement, makes input gear Z2 rotate on power shaft 1, makes output shaft 2,3 rotate more steady.
As it is shown on figure 3, in like manner, when on the internal spline 41 of clutch 4 and the external splines 11 of power shaft 1 and input gear Z2
External splines connect time, when power shaft 11 rotates by input gear Z2 drive output gear Z5, output gear Z6 rotate, thus
Obtain another kind of output speed ratio combination.
In order to more be exported speed ratio combination.Can increase gear on power shaft 1 and output shaft 2,3, the most defeated
Entering the gear quantity on axle 1 and output shaft 2,3 is 3 or more than 3, so can more be exported speed ratio combination.
Embodiment 2
Difference from Example 1 is, in the present embodiment, output gear Z3, output gear Z4, output gear Z5,
Output gear Z6 is spindle rotationally arranged on output shaft 2,3 by bearing.2 output shafts 2,3 are equipped with clutch 4, and
This clutch 4 lays respectively between output gear Z3 and output gear Z5 and between output gear Z4 and output gear Z6.From
Clutch 4 is provided with internal spline 41, and output shaft 2,3 is provided with the external splines corresponding with internal spline 41, equally, output gear Z3,
It also is provided with the external splines corresponding with clutch 4 on output gear Z5 and output gear Z4, output gear Z6.
So arrange, as shown in Figure 6, when power is transmitted by output gear Z3, output gear Z4 by input gear Z1,
Obtain one output speed ratio, and two output shaft 2,3 equispeed outputs.Equally, as it is shown in figure 5, power can also be by input gear
Z2 is transmitted by output gear Z5, output gear Z6, it is also possible to obtain a kind of output speed ratio combination.
As shown in Figure 8, when clutch 4 on the output shaft 3 in left side bonded with output gear Z4, and in the output on right side
On axle 2 bonded with output gear Z5 time, power is by input gear Z1 and output gear Z4, input gear Z2 and output gear
Z5 transmits., it is possible to obtain a kind of output speed ratio combination, and two output shafts 2,3 are variable speed output at this moment.
Equally, as it is shown in fig. 7, power is by input gear Z1 and output gear Z3, input gear Z2 and output gear Z6
Transmission.At this moment, it is also possible to obtain a kind of output speed ratio combination.
The principle of above-described embodiment only illustrative present invention and effect thereof, not for limiting the present invention.Any ripe
Above-described embodiment all can be modified under the spirit and the scope of the present invention or change by the personage knowing this technology.Cause
This, have usually intellectual such as complete with institute under technological thought without departing from disclosed spirit in art
All equivalences become are modified or change, and must be contained by the claim of the present invention.
