産業上の利用分野
本発明は、換気扇、空調機等に使用される羽根に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to blades used in ventilation fans, air conditioners, and the like.
従来の技術
従来のこの種の羽根は、一般に第３図に示すように、構
成されていた。すなわち、電動機シャフト嵌合部１１ａ
を有するアルミダイキャスト製のボス１１をピン１２で
羽根板１３に固定して構成されていた。BACKGROUND OF THE INVENTION Conventional blades of this type have generally been constructed as shown in FIG. That is, the motor shaft fitting portion 11a
It was constructed by fixing an aluminum die-cast boss 11 having a shape to a vane plate 13 with a pin 12.
発明が解決しようとする課題 このような従来の構成では以下のような課題があった。Problems that the invention aims to solve Such a conventional configuration has the following problems.
電動機（図示せず）から電気振動がわずかでも起きた場
合、この電気振動が、電動機シャフトから電動機シャフ
ト嵌合部１１ａを通って、羽根へと伝わり、羽根で増幅
されて大きな音を発生してしまうという場合があった。If even a slight electric vibration occurs from the electric motor (not shown), this electric vibration is transmitted from the motor shaft to the blade through the motor shaft fitting part 11a, and is amplified by the blade and generates a loud sound. There were times when I had to put it away.
本発明は、このような課題を解決するもので、電動機シ
ャフト嵌合部から羽根への電気振動の伝播をなくし、低
騒音の羽根を実現することを目的とするものである。The present invention is intended to solve these problems, and aims to eliminate the propagation of electric vibrations from the motor shaft fitting portion to the blade, and to realize a low-noise blade.
課題を解決するための手段
この課題を解決するために本発明は、耐熱性樹脂製の電
動機シャフト嵌合部を内部に有するボスを備えた羽根を
構成したものである。Means for Solving the Problems In order to solve this problem, the present invention comprises a blade having a boss having a heat-resistant resin electric motor shaft fitting part inside.
作 用
この構成により、電動機より発生した電気振動は、羽根
の電動機シャフト嵌合部が耐熱樹脂製であるため、その
振動が吸収され、羽根への振動の伝播が遮断されること
となる。Function: With this configuration, the electric vibrations generated by the electric motor are absorbed because the motor shaft fitting portion of the blade is made of heat-resistant resin, and the propagation of the vibration to the blade is blocked.
実施例
以下、本発明の一実施例を第１図および第２図にもとづ
き説明をする。EXAMPLE Hereinafter, an example of the present invention will be explained based on FIGS. 1 and 2.
遠心７アン１の羽根板６の中心部に羽根ボス３がビン４
によって絞め固定されている。羽根ボス３の内部には、
その中央に図示しない電動機のシャフトが嵌合される耐
熱性樹脂製の電動機シャフト嵌合部２が接着剤にて接合
されている。A blade boss 3 is attached to the center of the blade plate 6 of the centrifugal 7-an 1.
It is tightened and fixed by. Inside the vane boss 3,
A motor shaft fitting part 2 made of heat-resistant resin, into which the shaft of an electric motor (not shown) is fitted, is bonded to the center with an adhesive.
上記構成において、電動機から電気振動が発生すると、
電動機シャフトを通って遠心ファン１の羽根ボス３に伝
わっていくが、羽根ボス３の電動機シャフト嵌合部２は
耐熱性樹脂製であるため、この電気振動が明らかに故障
によるものほど大きくなければ、ここで吸収され、羽根
板６への伝播が遮断される。In the above configuration, when electric vibration is generated from the electric motor,
The electric vibration is transmitted to the blade boss 3 of the centrifugal fan 1 through the electric motor shaft, but since the electric motor shaft fitting part 2 of the blade boss 3 is made of heat-resistant resin, this electric vibration is clearly not large enough to be caused by a failure. , where it is absorbed and its propagation to the vane plate 6 is blocked.
したがって、遠心ファン１によって、電気振動が増幅さ
れて大きな音を発生することを確実に防止できることと
なる。Therefore, the centrifugal fan 1 can reliably prevent electric vibrations from being amplified and generating loud noises.
なお、実施例では、羽根を遠心ファン１について説明し
たが、他の軸流ファン等でも、その作用効果になんら差
異を生じない。In the embodiment, the description has been made regarding the blades of the centrifugal fan 1, but there will be no difference in the operation and effect when using other axial fans or the like.
発明の効果
以上の実施例の説明から明らかなように本発明によれば
、羽根ボスの電動機シャフト嵌合部が耐熱性樹脂ででき
ているので、電動機の電気振動がこの部分で吸収されて
羽根への伝播が遮断され、異常音等の発生のない、低騒
音の羽根を実現できるという効果が得られる。Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the motor shaft fitting part of the blade boss is made of heat-resistant resin, so the electric vibration of the motor is absorbed by this part and the blade The effect of this is that it is possible to realize a low-noise blade that does not generate abnormal noise or the like.
