Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following instance is used for illustrating the present invention, but is not limited to the scope of the present invention.
Shown in reference Fig. 1 and 2, the coaxial pneumatic vane motor of the present invention, including: distribution
Valve (not shown), cylinder 1, dead axle 5, output shaft the 4, first vane group 6 and the second leaf
Sheet group 7, cylinder 1 includes cylinder barrel 2 and for covering the end cap 3 of cylinder barrel 2, cylinder barrel 2 interior
Portion's cavity is hollow cylindrical, and end cap 3 is removably connected with cylinder barrel 2 by flange, covers cylinder
The opening of cylinder 2.The circumference of cylinder barrel 2 sidewall is provided with multiple pore 21, in the present embodiment,
Multiple pores 21 are connected with distributing valve respectively, and distributing valve is for changing the air inlet of pore, giving vent to anger
State.Distributing valve is connected with external air source, and many group pores 21 are divided into some groups, external air source
Change gas pore 21 by distributing valve to supply to some groups of pores 21 respectively.Dead axle 5 is fixed
In the inside bottom of cylinder barrel 2, and arrange with the coaxial of cylinder barrel；Output shaft 4 is rotationally
It is located on end cap 3, and coaxially arranged with dead axle.Shown in reference Fig. 1, in the present embodiment,
One end of dead axle 5 fixes with the inside bottom of cylinder barrel 2, and the other end is by axle sleeve 8 and output
One end of axle 4 is connected；The other end of output shaft 4 passes end cap 3, stretches out cylinder barrel 2, uses
In output power.Dead axle 5 is provided with the first forward bearing 51 and the second forward bearing 52, the
The inner ring of one forward bearing 51 and the second forward bearing 52 is fixed on dead axle 5；Output shaft 4
It is provided with the first reverse bearing 41 and the second reverse bearing 42, the first reverse bearing 41 and
The inner ring of two reverse bearings 42 is fixed on output shaft 4.First vane group 6 is fixed on first
On forward bearing 51 and the first reverse bearing 41, the first vane group 6 includes 3 blades, 3
Individual blade is along the circumference uniformly arrangement of output shaft 4 and dead axle 5, and i.e. 3 blades uniformly arrange ground
It is fixed on the first forward bearing 51 and outer ring of the first reverse bearing 41；Second vane group 7 is solid
Being scheduled on the second forward bearing 52 and the second reverse bearing 42, the second vane group 7 includes 3
Blade, 3 blades are along output shaft 4 and circumferential uniformly arrangement, i.e. 3 blades of dead axle 5
Uniformly it is fixed on the second forward bearing 52 and outer ring of the second reverse bearing 42 to arrangement.First
Vane group 6 is identical with the blade quantity of the second vane group 7, the first vane group 6 and the second blade
The blade stagger arrangement of group 7.
In order to change torque and the rotating speed of air motor, according to the power demand of air motor, can

Direction, merely to represent forward bearing contrary with the rotation direction of reverse bearing.
With reference to shown in Fig. 3 A to 3C: in Fig. 3 A, the air inlet of pore 21, discharge directions, respectively
As shown in figure cathetus arrow, blade the forward () stress of the first vane group 6 in Fig. 1 clockwise,
The blade of the second vane group 7 reversely (counterclockwise in Fig. 1) stress.Due to the second vane group 7 not
Can rotate backward around dead axle 5, the first vane group 6 can rotate forward around dead axle 5, but can not be around defeated
Shaft 4 rotates forward, and therefore, the first vane group 6 drives output shaft 4 to rotate forward.
When the first vane group 6 arrives the state shown in Fig. 3 B, distributing valve switches gas as required
Hole 21 air inlet, discharge directions.As shown in Figure 3 C, the blade forward (up time of the second vane group 7
Pin) stress, the blade of the first vane group 6 reversely (counterclockwise) stress.First vane group 6
Can not rotate backward around dead axle 5, the second vane group 7 can rotate forward around dead axle 5, but can not be around
Output shaft 4 rotates backward, so the second vane group 7 drives output shaft 4 to rotate forward.
The air inlet of distributing valve, discharge directions is back and forth switched, it is achieved the first blade according to above-mentioned steps
Group 6 and the alternate-running of the second vane group 5, thus drive output shaft 4 to continuously run, transport continuously
The output shaft 4 turned outwards exports power.
The coaxial pneumatic vane motor of the present invention, cylinder barrel, dead axle and output shaft be coaxially disposed,
Being provided with multiple pore on the sidewall of cylinder barrel, multiple pores are connected with distributing valve respectively, distributing valve
The switching air inlet of pore, exhaust condition, make the first vane group and the second vane group drive by turns
Output shaft rotation, thus export power, the output shaft of the present invention and the coaxially arranged structure of dead axle
Make power consumption penalty little, improve the efficiency of air motor, output and moment of torsion.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention,
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made,
