Abstract
The utility model discloses an axial-flow type ventilation blower, it includes frame, motor, wheel hub and blade, the blade is fixed on wheel hub, and wheel hub fixes on the motor shaft, wheel hub includes the axle sleeve and the hub body, the hub body links firmly on the axle sleeve, the end surface of motor is close to the hub body, inclines to keeping away from the motor direction from axle sleeve junction to the hub body periphery. The inclination is preferably an arc inclination. The hub body has an opening on the opposite end surface near the motor, and a sealing cover is arranged on the opening. According to the scheme, the hub body is close to the end face of the motor, and inclines towards the direction away from the motor from the shaft sleeve connection part to the periphery of the hub body, so that the hub of the ventilator has a good streamline, the resistance of the hub to airflow during the work of the ventilator is reduced, the energy consumption can be saved, the noise can be reduced, and meanwhile, the characteristics of simple structure, convenience in processing and the like of the ventilator are guaranteed.
Description
Technical field
The utility model relates to a kind of ventilation equipment, especially a kind of axial fan.
Background technique
Axial fan is widely used in industrial fields such as oil, chemical industry, metallurgy, mine, electric power, traffic, tobacco, also is applied to civilian installations such as heating, ventilation, air conditioning.Existing axial fan is from practical application, and inefficient and strong noise is still the subject matter in the fan operation.Along with the raising of energy saving and environmental consciousness, people are more and more higher to improving fan efficiency and reducing the cry of noise, so high efficiency, low noise ventilator have important use and be worth.
As disclosed " high-efficient low-noise built-up shaft flow fan " patent documentation (publication number: CN2307948) in State Intellectual Property Office's on February 17th, 1999, the disclosed axial-flow blower of document is to be made of support, casing, wheel hub and blade, vanes fixed is on wheel hub, wheel hub is fixed on motor on the motor shaft and is fixed on the centre of casing by supporting element, and the cylindrical and the support of casing join.Characteristics such as that this axial-flow blower has is simple in structure, be easy to processing, easy to use, but energy-saving and cost-reducing, reduce noise etc. the aspect be still empty and further improve.
The model utility content
At the problems referred to above, the problem that the utility model quasi-solution is determined provides a kind of have simple in structure, saving energy, axial fan that noise is low.
For addressing the above problem, the utility model has adopted following technological scheme: a kind of axial fan, it comprises support, motor, wheel hub and blade, described vanes fixed is on wheel hub, wheel hub is fixed on the motor shaft, and described wheel hub comprises axle sleeve and hub body, and described hub body is connected on the axle sleeve, described hub body is near the end face of motor, from the axle sleeve joint to hub body periphery to tilting away from motor drive direction.
Described hub body is near the end face of motor, is preferably arc to the inclination away from motor body peripheral direction from the axle sleeve joint to hub body periphery.
Described hub body is equipped with sealing cover having an opening near on the opposing end surface of motor on the opening.Described hub body periphery is provided with two or two above blade installation mouths.The end face of described hub body periphery is an arc.
Adopted such scheme, the hub body is near the end face of motor, from the axle sleeve joint to hub body periphery to tilting away from motor drive direction, make the wheel hub of ventilator have good streamline, wheel hub is to the resistance of air-flow when reducing ventilator work, so not only can energy efficient, and can also reduce noise, also guaranteed characteristics such as ventilator structure is simple, easy to process simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model axial fan;
Fig. 2 is the structural representation of wheel hub.
Among the figure: 1-support, 2-motor, 3-motor shaft, 4-wheel hub, 5-blade, 6-opening, 7-axle sleeve, 8-hub body, 9-hub body periphery, 10-blade installation mouth, 11-sealing cover.
Embodiment
As shown in the figure, axial fan of the present utility model, it comprises support 1, motor 2, wheel hub 4 and blade 5, blade 5 is fixed on the wheel hub 4, wheel hub 4 is fixed on the motor shaft 3, and described wheel hub 4 comprises axle sleeve 7 and hub body 8, and described hub body 8 is connected on the axle sleeve 7, said structure is identical with axial fan of the prior art, therefore is not described in detail.
Referring to Fig. 2, axial fan of the present utility model mainly is to have done a series of improvement on the hub body 8 of wheel hub 4, the one, and hub body 8 preferably is equipped with sealing cover (11) having an opening 6 near on the opposing end surface of motor 2 at this opening 6; The 2nd, described hub body 8 is near the end face of motors 2, from axle sleeve 7 joints to hub body periphery 9 to tilting away from motor 2 directions, this inclination is preferably arc; The 3rd, the end face of described hub body periphery is an arc.Hub body periphery 9 is provided with two or two above blade installation mouths 10 (present embodiment is an example with three blade installation mouths).Through above-mentioned improvement, make the wheel hub of ventilator have good streamline, wheel hub so not only can energy efficient to the resistance of air-flow when reducing ventilator work, and can also reduce noise, has also guaranteed characteristics such as ventilator structure is simple, easy to process simultaneously.
