Coaxial-type roller gear speed changer 6 is located between two impellers, and two impellers rotation direction on the contrary, in this way,
It just can produce to rotation.
In the present embodiment, to make the rotation direction of two impellers on the contrary, in other words, coaxial-type roller gear speed changer need to be made
The rotation direction of the output shaft 69 of the rotation direction and coaxial-type roller gear speed changer 6 of 6 input shaft 67 is opposite.
As shown in fig.4, specifically, which is located in shell 300, and coaxial-type circle
Stud wheel speed changer 6 further include cabinet 61, retaining piece, first gear 62, second gear 63, third gear 64, the 4th gear 65,
5th gear 66 and transmission shaft 68, wherein center between first gear 62, third gear 64 away from the 4th gear the 65, the 5th
Away from equal, second gear 63 is carrier gear at the center of gear 66.
The part input shaft 67 of coaxial-type roller gear speed changer 6 can be mounted in cabinet 61 by bearing.
First gear 62 is mounted on the input shaft 67 of coaxial-type roller gear speed changer 6, first gear 62 and coaxial-type
To rotate synchronously between the input shaft 67 of roller gear speed changer 6, specifically first gear 62 can be made to be mounted on coaxially by key
On the input shaft 67 of formula roller gear speed changer 6.
Second gear 63 is meshed with first gear 62, as a result, when first gear 62 rotates, drives second gear 63
Rotation, and the rotation direction of first gear 62 is opposite with the rotation direction of second gear 63.
Transmission shaft 68 is mounted in cabinet 61, and the length of transmission shaft 68 is greater than the coaxial-type Cylinder Gear being located in cabinet 61
67 length of input shaft of wheel speed 6.
Third gear 64 and the 4th gear 65 are mounted on transmission shaft 68, and third gear 64 is close to transmission shaft 68
One end, the 4th gear 65 is close to the other end of transmission shaft 68, and specifically, third gear 64 can be pacified with the 4th gear 65 by key
On transmission shaft 68, wherein third gear 64 is meshed with second gear 63, under the drive of second gear 63, third tooth
Wheel 64 rotates with it, and the rotation direction of the rotation direction of third gear 64 and second gear 63 is on the contrary, third gear 64 turns
Dynamic direction is identical as the rotation direction of first gear 62, and since third gear 64 and the 4th gear 65 are fixedly mounted on transmission
On axis 68, then the rotation direction of third gear 64 is identical as the rotation direction of the 4th gear 65.
The part output shaft 69 of coaxial-type roller gear speed changer 6 is mounted in cabinet 61, wherein in cabinet 61
69 length of output shaft of coaxial-type roller gear speed changer 6 is less than the length of transmission shaft 68.
5th gear 66 is mounted on the output shaft 69 of coaxial-type roller gear speed changer 6, the 5th gear 66 and the 4th tooth
Wheel 65 is meshed, and to rotate synchronously between the 5th gear 66 and the output shaft 69 of coaxial-type roller gear speed changer 6, the 4th
Under the drive of gear 65, the 5th gear 66 is rotated with it, according to it is aforementioned it is found that the 5th gear 66 rotation direction respectively with third
Gear 64, the 4th gear 65 are on the contrary, it follows that the rotation direction phase of the rotation direction of the 5th gear 66 and first gear 62
Instead, to realize the rotation direction and coaxial-type roller gear speed changer 6 of the input shaft 67 of coaxial-type roller gear speed changer 6
The rotation direction of output shaft 69 is on the contrary, specifically, the 5th gear 66 can be mounted on coaxial-type roller gear speed changer 6 by key
On output shaft 69.
As shown in fig.4, wherein, retaining piece divides cabinet 61 for the first cavity and the second cavity.
First gear 62, second gear 63, third gear 64 and coaxial-type roller gear speed changer 6 part input shaft 67
It is respectively positioned in the first cavity, the part output shaft 69 of the 4th gear 65, the 5th gear 66 and coaxial-type roller gear speed changer 6 is equal
In the second cavity, the part input shaft 67 of coaxial-type roller gear speed changer 6 is side and the barrier for being mounted on cabinet 61
Between part, the part output shaft 69 of coaxial-type roller gear speed changer 6 is mounted between the other side and retaining piece of cabinet 61.
The axial line of 64 three of first gear 62, second gear 63 and third gear is located along the same line；Due to first
The diameter of gear 62, second gear 63 and third gear 64 is smaller compared with the 4th gear 65, the 5th gear 66, in addition, the first tooth
Wheel 62, second gear 63 and third gear 64 triangular in shape can also be distributed, i.e. first gear 62, second gear 63 and third tooth
The respective axial line of 64 threes is taken turns to be parallel to each other but not in the same plane.
The rotation direction of input shaft 67 and output shaft 69 can be realized due to the coaxial-type roller gear speed changer 6 on the contrary,
Therefore, the ventilation blower only need a motor 110 and matched electric-control system can be realized two impellers to rotation, to greatly drop
The low manufacturing cost of the ventilation blower, also reduces the volume size of the ventilation blower, constructs field for tunnel, tunnel etc.
Institute, the smaller ventilation blower of volume are more favored, and facilitate the operation of construction site.
As shown in fig.1, to further decrease the axial length of shell 300, two impellers are divided into the first impeller 1 and second
Impeller 8, the first impeller 1 are located between coaxial-type roller gear speed changer 6 and collector 100, and the second impeller 8 is located at coaxial-type circle
Between stud wheel speed changer 6 and diffuser 200, the output shaft of power source and the input shaft 67 of coaxial-type roller gear speed changer 6
Between connected by connector, the middle part of first flange 3 is then fixedly connected with the first propeller boss 2, specifically, can be in the first impeller 1
Side open up groove, be embedded first flange 3 in groove, first flange 3 is connected with connector, first flange 3 with connect
It is attached between part by bolt 5, is led between the output shaft of power source and the input shaft 67 of coaxial-type roller gear speed changer 6
Cross connector connection.
In the present embodiment, connector is only with the wherein half in a complete shaft coupling 4.As a result, in realization pair
While the output shaft of power source and the input shaft 67 of coaxial-type roller gear speed changer 6 are connected with each other, the first leaf is also reduced
The distance between 1 and shaft coupling 4 are taken turns, that is, reduces the axial length of shell 300.
To sum up, this is to the structurally reasonable of axial flow rotary booster, only with a motor 110 and mating electric-control system
Can be realized two impellers to rotation, greatly reduce manufacturing cost, meanwhile, the structure inside the axial flow rotary booster is tight
It gathers, also reduces the length of axial flow rotary booster axial direction, reduce the occupancy to construction site space.
