Abstract
This invention relates to a wind wheel, in particular to a low-noise wind wheel which comprises a wind wheel shell and a soft damping ring, wherein a bracket plate is installed in the wind wheel shell; a metal shaft sleeve is coated in the soft damping ring; the soft damping ring adopts a damping material with proper hardness the outer ring of the center hole of the bracket plate is provided with a die casting hole; the soft damping ring partially penetrates through the die casting hole and is integrally die-casted on the two end faces of the bracket plate; and the upper and lower end faces of the metal shaft sleeve are both coated by the soft damping ring. The low-noise wind wheel greatly reduces the operation nose of a draught fan, and simultaneously reduces the design requirement on a motor and lowers the manufacturing cost of the motor. The soft damping ring is made of the damping material, thereby ensuring good damping performance and effectively preventing the end faces of the metal shaft sleeve from rusting.
Description
Technical field
The present invention relates to a kind of wind wheel, especially a kind of low noise wind wheel.
Background technique
The running of wind wheel is by motor-driven.Motor is in operation process, because air-gap field not only has first-harmonic (50Hz, 60Hz), and also have a series of higher harmonicss to exist, especially the active force of the higher harmonics of 3 powers, 5 powers, 7 powers generation easily and after the metal wind wheel generation resonance noise occurs.Traditional wind wheel as shown in Figure 1, metal axle sleeve is directly to be fitted on the supporting plate, when with traditional wind wheel and the direct-connected operation of motor rigidity, particularly vibration is big when low cruise, relatively is easy to generate noise.Simultaneously, this class noise is responsive especially to the variation of blower fan steel plate thickness, and is also responsive especially to the circularity of the air-gap field of motor operation, so this puzzlement for a long time becomes the difficult problem that the central air-conditioner end prod reduces noise in the industry.
According to original wind wheel product specification manufacture process, often can only increase the steel plate thickness of wind wheel or significantly increase the silicon steel plate consumption of motor and the enameled cable consumption with air gap flux density that reduces motor and the method (speed governing of T type) of improving the magnetic field circularity of motor, this method is to be cost to increase raw materials consumption and to sacrifice manufacturability, is unfavorable for the lifting of product price ratio.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, solve the big technical problem of the easy resonance noise of conventional wind wheel, the invention provides a kind of low noise wind wheel.
The technical solution adopted for the present invention to solve the technical problems is: a kind of low noise wind wheel, comprise the wind wheel shell, in the wind wheel shell supporting plate is installed, described low noise wind wheel also includes soft damping ring, be enclosed with metal axle sleeve in the soft damping ring, described soft damping ring is fixed on the supporting plate by integral body casting pressure mode.
Further, the both ends of the surface up and down of described metal axle sleeve are all wrapped up by soft damping ring, can completely cut off metal axle sleeve effectively and contact with air, prevent that metal axle sleeve from getting rusty.
In order to guarantee the favorable damping performance, described soft damping ring adopts damping material.
To press conveniently in order casting, and combine more firmly with supporting plate, the center hole outer ring of described supporting plate has casting and presses the hole, and described soft damping ring partly passes casting and presses hole and whole the casting to be pressed on the both ends of the surface of supporting plate.
The invention has the beneficial effects as follows: low noise wind wheel of the present invention is that the damping material with suitable stiffness carries out integral body casting pressure between metal axle sleeve and supporting plate, the electric and magnetic oscillation that the various harmonic waves of motor are produced has carried out effective decay and isolation, greatly reduce the noise of fan operation, also significantly reduced simultaneously designing requirement, reduced the manufacture cost of motor motor.Adopt the damping ring of soft damping material, not only guaranteed the favorable damping performance, prevent effectively that also the metal axle sleeve end face from getting rusty.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a structural representation of the present invention;
Wherein: 1. supporting plate, 2. soft damping ring, 3. metal axle sleeve.
Embodiment
A kind of as shown in Figure 2 low noise wind wheel, comprise the wind wheel shell, supporting plate 1 is installed in the wind wheel shell, the low noise wind wheel also includes soft damping ring 2, be enclosed with metal axle sleeve 3 in the soft damping ring 2, soft damping ring 2 adopts the damping material of suitable stiffness, as the rubber material of suitable stiffness, has better guaranteed vibration damping and has prevented that effectively metal axle sleeve from getting rusty.The center hole outer ring of supporting plate 1 has casting and presses the hole, and the part damping material of soft damping ring 2 pressed hole one side to be cast into opposite side from casting when casting was pressed, and the whole simultaneously casting of soft damping ring 2 coated metal axle sleeves 3 is pressed on the both ends of the surface of supporting plate 1.The both ends of the surface up and down of metal axle sleeve 3 are all by soft damping ring 2 parcels.
By using wind wheel of the present invention to solve the fan noise that is produced because of the motor harmonic effects effectively, the product up-gradation of central air conditioning terminal and ventilation system is had ground-breaking meaning, promote the use and have great economic value.
Above embodiment only in order to the explanation the present invention and and unrestricted technological scheme described in the invention; Therefore, although this specification has been described in detail the present invention with reference to the foregoing description,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention; And all do not break away from the technological scheme and the improvement thereof of the spirit and scope of the present invention, and it all should be encompassed in the claim scope of the present invention.
