Abstract
The utility model relates to an axial-flow fan, which comprises a motor, a rotation cylinder provided with an inclined blade and end covers at both ends of the rotation cylinder, wherein, a coupling is fixed to the center of the inner side of one end cover of the rotation cylinder. The coupling is connected with a motor shaft extending into the rotation cylinder, forming the axial-flow fan a distance of which between the rotation cylinder and the motor is narrow. The fan has the advantages of compact structure, reasonable element arrangement, increase of the effective length of the fan in the same space of an air conditioner indoor machine, enhancement of the space utilization of the indoor machine, reduction of the radial vibration amplitude of the fan, stable operation of the fan and low noise.
Description
The utility model relates to the improvement of indoor apparatus of air conditioner, specifically is a kind of axial-flow fan, and it belongs to the air conditioner technical field.
In the prior art, the employed axial-flow fan of indoor set mostly is the rotating cylinder that the inclined blade is housed, and the rotating shaft of stretching out in its end cap outer end is connected with motor shaft, constitutes the axial-flow fan that has overhanging rotating shaft.This fan is with after motor connects, because rotating shaft circle is between fan and motor, the distance between fan and the motor is bigger.Space between this segment distance can not be utilized, and causes the space availability ratio of indoor set low.Fan shaft outside stretching is in operation, and easily the generation Oscillation Amplitude is excessive, the drawback that noise is excessive.
The purpose of this utility model is to improve the space availability ratio of indoor set, strengthen the effective length of axial-flow fan, improve the annexation of each parts of indoor set, especially improve the structure of axial-flow fan, reach this fan structure compactness, connection and reasonable arrangement operates steadily, and reduces the circular runout drawback of fan operation.
Task of the present utility model is finished by following technological scheme, developed a kind of axial-flow fan, it comprises: motor, the rotating cylinder and the two ends end cap thereof of inclined blade are housed, in the inboard center fixation of a certain end cap of rotating cylinder coupling is arranged, this device connects with the motor shaft that stretches in rotating cylinder inside, constitutes rotating cylinder and the narrow and small axial-flow fan of spacing motor.
This axial-flow fan, described coupling, it is a permanent coupling, promptly in the inboard center fixation of end cap one section sleeve pipe rotating shaft is arranged, this rotating shaft is enclosed within on the motor shaft, and solid on motor shaft by bolt or pin pin.
Advantage of the present utility model has: move into rotating cylinder inside owing to change fan shaft into coupling, this has just dwindled the distance of fan and motor, in same space, just can increase fan length, the effective length of fan is increased, improved the indoor set space availability ratio.Because the fan end cap near the motor shaft root, improves fan shaft and motor shaft concentricity, the fan Oscillation Amplitude that is in operation is less, and running is steady, and noise is low, and air quantity is big.
Embodiment's accompanying drawings of the present utility model is as follows:
The structural representation of Fig. 1 axial-flow fan;
The structure partial enlarged view of Fig. 2 axial-flow fan.
Referring to Fig. 1, the indoor apparatus of air conditioner axial-flow fan that Fig. 2 makes, it comprises: motor 1, be equipped with the rotating cylinder 3 and the two ends end cap 4 thereof of inclined blade 2.On rotating cylinder 3 right sides or left side end cap 4 inboards be fixed with one section sleeve pipe rotating shaft 5, this rotating shaft 5 covers are through on the motor shaft 6, and are fixed on by bolt 7 and constitute rotating cylinder 3 and the narrow and small axial-flow fan of motor 1 spacing on the motor shaft 6 that stretches into rotating cylinder 3 inside.
Install between this axial-flow fan and the motor 1, not equidistant inclined blade 2 can be removed a blade 2, use spanner or spiral shell cutter to go deep in the sleeve pipe rotating shaft 5 of rotating cylinder 3 inside bolt 7 being tightened on the motor shaft 6.
Claims (2)
1, a kind of axial-flow fan, it comprises: motor, the rotating cylinder and the two ends end cap thereof of inclined blade are housed, and it is characterized in that: coupling is arranged in the inboard center fixation of a certain end cap of rotating cylinder, this device connects with the motor shaft that stretches in rotating cylinder inside, constitutes rotating cylinder and the narrow and small axial-flow fan of spacing motor.
2, according to the described axial-flow fan of claim 1, it is characterized in that: described coupling, it is a permanent coupling, promptly in the inboard center fixation of end cap one section sleeve pipe rotating shaft is arranged, this rotating shaft is enclosed within on the motor shaft, and solid on motor shaft by bolt or pin pin.
