Abstract
The utility model relates to an air conditioner vane component, belonging to the household electric appliance field. The component comprises a shaft sleeve and vanes which are molded by injection into a whole body; wherein the shaft sleeve includes an inner ring and an outer ring, the outer ring is nested outside the inner ring, and a buffer layer is arranged between the inner ring and the outer ring of the shaft sleeve. In the manufacture process, the buffer layer is adopted to ensure the inner ring of the shaft sleeve not to be deformed to influence the installation matching degree of a motor and the vanes; noise is removed while the working stability of the vanes is improved; therefore the utility model is worthy of promotion in the field.
Description
Technical field
The utility model relates to a kind of air-conditioning fan blade assembly, relates in particular to a kind of air-conditioning fan blade assembly that adopts split type axle sleeve, belongs to household electrical appliance technical field.
Background technique
In the market the air-conditioning generally sold, the manufacture process of its air-conditioning fan blade assembly is roughly as follows: the axle sleeve in the fan blade assembly is put into the fan blade mould, injection machine injects the molten plastic particle, and the aluminum component axle sleeve is embedded in the plastic blade.Furthermore, the plastics of fusion the time have contraction process in cooling, and axle sleeve is had the effect of extruding, and the size that can make axle sleeve that is bound to changes, and this variation is irregular, are not easy control, and then influence the installation matching of motor and fan blade.Moreover axle sleeve is a rigid construction, and causing motor and fan blade is to be rigidly connected, and causes motor to drive fan blade when starting or fluctuate and causes unusual rotation and noise occurs, can't satisfy the needs in client and market.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of air-conditioning fan blade assembly is provided.
The purpose of this utility model realizes by following technical solution:
The air-conditioning fan blade assembly includes axle sleeve, fan blade, and axle sleeve, fan blade are injection molded into an integral body, and wherein: described axle sleeve comprises axle sleeve inner ring, axle sleeve outer ring, and the axle sleeve outer ring is nested with and is installed in outside the axle sleeve inner ring.
The purpose of this utility model also can further realize by following technical measures:
Above-mentioned air-conditioning fan blade assembly wherein, is provided with buffer layer between described axle sleeve inner ring and the axle sleeve outer ring.
Further, above-mentioned air-conditioning fan blade assembly, wherein, described axle sleeve inner ring is provided with raised line.
Advantage of the present utility model is: the air-conditioning fan blade assembly that adopts the design, in manufacture process, can effectively avoid because the plastics of fusion produce disadvantageous extruding to axle sleeve when cooling, guarantee that the axle sleeve inner ring is indeformable, do not influence the installation matching of motor and fan blade.Moreover the simple rigid construction that axle sleeve is different from the past drives fan blade and unusual rotation occurs when avoiding electric motor starting or fluctuation by the elasticity of rubber, when increasing the fan blade working stability, removed noise.Therefore, the utility model can have follows the needs that satisfy client and market, is worth promoting in the art.
The purpose of this utility model, advantage and characteristics will illustrate by following preferential embodiment's non-limitative illustration and explain that these embodiments only provide as an example with reference to accompanying drawing.

Embodiment
Air-conditioning fan blade assembly as shown in Figure 1 and Figure 2, include axle sleeve, fan blade 5, axle sleeve, fan blade 5 are injection molded into an integral body, what it was special goes out to be: described axle sleeve comprises axle sleeve inner ring 1, axle sleeve outer ring 2, axle sleeve outer ring 2 is nested with and is installed in outside the axle sleeve inner ring 1, is provided with buffer layer between axle sleeve inner ring 1 and the axle sleeve outer ring 2.Furthermore, in order to play better buffer function, the buffer layer between axle sleeve inner ring 1 and the axle sleeve outer ring 2 is a rubber 3.From stressed degree, axle sleeve inner ring 1 adopts aluminium product with axle sleeve outer ring 2.Simultaneously, described axle sleeve inner ring 1 is provided with raised line 4, can carry out certain location to rubber 3.
In the production and assembly process of air-conditioning fan blade assembly reality, the outer surface of axle sleeve outer ring 2 directly contacts with plastic blade 5, and both are injection molded into an integral body.Specifically, when fan blade 5 carried out the injection moulding cooling, the molten plastic of contraction only produced active force to the outer ring of axle sleeve, and the outer ring size is changed.Again further combined with Fig. 2, owing to be provided with rubber 3 buffer layers between axle sleeve inner ring 1 and the axle sleeve outer ring 2, rely on the elasticity of rubber 3 self to absorb the active force that is transmitted from axle sleeve outer ring 2, therefore when fan blade 5 coolings, any variation does not take place in the size of axle sleeve inner ring 1.
Finally, the internal surface of axle sleeve inner ring 1 and motor link together.When electrical power rotates, drive fan blade 5 choosing commentaries on classics by connecting rubber 3, under the effect of rubber 3, have certain elasticity, therefore can effectively reduce the starting torque of fan blade 5, also just can eliminate the startup noise of fan blade 5.Simultaneously, in running, fan blade 5 is adjustment automatically, and the power that keeps all blades to be subjected to is the same, can reduce the operation noise, makes fan blade 5 stablize high speed rotating.
From above-mentioned text description also in conjunction with the accompanying drawings as can be seen: the air-conditioning fan blade assembly that adopts the design, in manufacture process, can effectively avoid because the plastics of fusion produce disadvantageous extruding to axle sleeve when cooling, guarantee that axle sleeve inner ring 1 is indeformable, do not influence the installation matching of motor and fan blade 5.Moreover the simple rigid construction that axle sleeve is different from the past drives fan blade 5 and unusual rotation occurs when avoiding electric motor starting or fluctuation by the elasticity of rubber 3, when increasing fan blade 5 working stabilitys, removed noise.Therefore, the utility model can have follows the needs that satisfy client and market, is worth promoting in the art.
Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the utility model scope required for protection.
