Abstract
The utility model relates to a vibration absorption structure of an external rotor fan casing, which comprises a fan casing and a vibration absorption rubber ring, and is characterized by also comprising a shaft sleeve and a connecting steel sheet ring, and a sleeve fixed by the vibration absorption ring is arranged outside the shaft sleeve; and one side of the connecting steel sheet ring and the vibration absorption rubber ring are fixed together, and the other side of the connecting steel sheet ring and the fan casing are fixed together. The concentricity of rubber components and the fan casing is good, so that the loosening phenomenon of the fan casing and the vibration absorption structure is prevented, the installation is simplified, the labor cost is saved, the production efficiency is improved, and the vibration absorption effect is good.
Description
Technical field
The utility model relates to a kind of outer rotor blower fan vibration damping structure, especially relates to a kind of outer rotor blower fan casing vibration damping structure.
Background technique
At present, most on the market outer rotor blower fan casing vibration damping structure is design like this:
One, as shown in Figure 1, the vibration damping structure of some outer rotor blower fan casing on the market, vibration isolation rubber (2) is separated with fan casing (1), (3), major part all can be screwed again, such structure, means of fixation is steady inadequately, and the compression height of rubber is inconsistent, can cause that fixed body tilts.Secondly, because two faces of fan casing 1 and 2 need so to have kept apart with rubber, but screw has passed fan casing from top to bottom and rubber fixes, and the vibration of blower fan inside still can be delivered on the flow blower casing, so do not reach real effectiveness in vibration suppression.
Two, as shown in Figure 2, go back the vibration damping structure of some outer rotor blower fan casing on the market, vibration isolation rubber (2) is also separated with fan casing (1), (3), but be not screwed, but fix with the shape and the fan casing close-fitting of rubber itself, because rubber is soft, energy compressive strain can cause the concentricity of entire mechanism bad.Secondly, because rubber separates with fan casing, there be not the fixing of other, so occur the phenomenon that gets loose in transit easily.
Summary of the invention
Many deficiencies based on the above-mentioned casing of outer rotor blower fan on the market vibration damping structure, the utility model aims to provide and a kind ofly can improve the blower fan transmitting vibrations, can improve the product concentricity again, can simplify again install and prevent to occur in the transportation process get loose phenomenon and the outer rotor blower fan vibration damping structure that designs.
For realizing this purpose, the utility model is taked following technological scheme: a kind of outer rotor blower fan casing vibration damping structure on it comprises fan casing and vibration isolation rubber circle; It is characterized in that: also comprise axle sleeve and connect steel sheet ring, what the vibration isolation rubber circle was fixing is set in outside the axle sleeve, connects steel sheet ring one side and vibration isolation rubber circle and fixes, and opposite side and fan casing are fixed.
The utility model compared with prior art, the present invention has following advantage:
1, rubber assembly and fan casing together are put into injection moulding in the mould, the rubber assembly and the fan casing good concentricity that have location, injection moulding to come out on the mould;
2, because be integral molded plastic together, prevented fan casing and vibration damping structure the appearance the phenomenon that gets loose;
3, the Blower Housing that comes out of injection moulding directly just can be installed, and does not need to install in addition vibration isolation rubber or mounting screw again, has simplified installation, has saved human cost, has improved manufacturing efficiency;
4, the mechanism of Blower Housing and inside separates with vibration isolation rubber fully, does not contact with each other, and such structure has better effectiveness in vibration suppression.
Description of drawings
Fig. 1 is the structural representation of background technique one;
Fig. 2 is background technique two structural representations;
Fig. 3 is the new structural representation of the utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 3, a kind of outer rotor blower fan casing vibration damping structure comprises fan casing 1,3 and vibration isolation rubber circle 2 on it; The utility model characteristics are: also comprise axle sleeve 4 and connect steel sheet ring 5, what the vibration isolation rubber circle was fixing is set in outside the axle sleeve, connects steel sheet ring one side and vibration isolation rubber circle and fixes, and opposite side and fan casing are fixed.During production, axle sleeve 4, vibration isolation rubber circle 2, connection steel sheet ring 5 form rubber assembly by the vulcanization of rubber, and rubber assembly becomes new vibration damping structure by with fan casing 1,3 molding and forming.
Those skilled in the art should know, any being equal to replacement and should being not enough to exceed protection domain of the present utility model of making based on spirit of the present utility model.
