(57) [Summary] (Modified) [Purpose] To provide a fan for an internal combustion engine that is lightweight and simple. A spider 1 having a plurality of holes 1b formed in the surface of each arm 1a is provided, and each arm 1a is provided with each resin so that the resin of a resin blade 2 is filled in each hole 1b. The blade 2 was embedded in the blade 2.
Description
【０００１】[0001]
本考案は、内燃機関用ファンに係わり、殊に樹脂製ブレードを備えた内燃機関 用ファンに関する。 The present invention relates to a fan for an internal combustion engine, and more particularly to a fan for an internal combustion engine having a resin blade.
【０００２】[0002]
樹脂を用いた内燃機関用ファンは、該内燃機関が低出力ならば、ファン全体を 樹脂で構成し、また該内燃機関が高出力ならば、図２に示すように、樹脂製ブレ ード２０を外周に固設してなる金属製インサート３０を金属製スパイダ１０にリ ベット４０等によって固定して構成するのが普通である。 A fan for an internal combustion engine using a resin, if the internal combustion engine has a low output, the entire fan is made of resin, and if the internal combustion engine has a high output, as shown in FIG. It is usual that the metal insert 30 formed by fixing the above to the outer periphery is fixed to the metal spider 10 with the rivet 40 or the like.
【０００３】[0003]
ところで内燃機関用ファンは、駆動馬力の軽減や駆動軸の応力低減のため、可 能な限り軽量化及び簡素化することが望ましい。ところが上記樹脂製ブレードを 備える内燃機関用ファンは、樹脂製ブレード、金属製インサート及び金属製スパ イダの主要３部品について、これらをこれ以上、軽量化及び簡素化するには困難 な段階にきている。 By the way, it is desirable to reduce the weight and simplify the internal combustion engine fan as much as possible in order to reduce the driving horsepower and the stress on the driving shaft. However, the internal-combustion-engine fan equipped with the resin blades described above is in a difficult stage to reduce the weight and simplification of the resin blade, metal insert, and metal spider, which are the three main components. There is.
【０００４】 本考案は、上記実情に鑑み、より軽量化及び簡素化し得る樹脂製ブレードを備 えた内燃機関用ファンを提供することを目的とする。In view of the above situation, an object of the present invention is to provide a fan for an internal combustion engine equipped with a resin blade that can be made lighter and simpler.
【０００５】[0005]
上記目的を達成するため、本考案に係わるファンは、図１を参照して説明すれ ば、各アーム１ａの面内に複数個の孔１ｂを設けたスパイダ１を備え、前記各孔 １ｂ内にも樹脂製ブレード２の樹脂が充填されるように、各アーム１ａが前記各 樹脂製ブレード２内に埋設されてなる構成とした。かかる構成によれば、樹脂製 ブレード２はスパイダ１に確実に固設されるようになる。 In order to achieve the above object, the fan according to the present invention comprises a spider 1 having a plurality of holes 1b formed in the surface of each arm 1a, as described with reference to FIG. Also, each arm 1a is embedded in each resin blade 2 so that the resin of the resin blade 2 is filled. According to this structure, the resin blade 2 is securely fixed to the spider 1.
【０００６】[0006]
図１は、実施例なる内燃機関用ファンの部分正面図である。ブレード２は樹脂 製である。他方スパイダ１は金属製であって、各アーム１ａの表面には複数個の 孔１ｂが設けられている。ところでこの孔１ｂ内には前記ブレード２を構成する 樹脂が充填されており、ブレード２とスパイダ１とを固設し、一体化している。 FIG. 1 is a partial front view of an internal combustion engine fan according to an embodiment. The blade 2 is made of resin. On the other hand, the spider 1 is made of metal, and a plurality of holes 1b are provided on the surface of each arm 1a. By the way, the hole 1b is filled with the resin constituting the blade 2, and the blade 2 and the spider 1 are fixed and integrated.
【０００７】 上記実施例は、樹脂成形時に構成したものである。即ち、予めブレード２の型 内にスパイダ１のアーム１ａを配置した後、該型内に軟化樹脂を押し込み、これ を硬化させて得られた構成である。The above embodiment is constructed at the time of resin molding. That is, the arm 1a of the spider 1 is placed in the mold of the blade 2 in advance, the softening resin is pushed into the mold, and this is hardened.
【０００８】 上記実施例によれば、従来技術における樹脂製ブレード、金属製インサート及 び金属製スパイダ３０との主要３部品の内、金属製インサートを省略して構成し てあるため、大幅な軽量化及び簡素化を達成することができる。According to the above embodiment, the metal insert is omitted from the three main parts of the resin blade, the metal insert and the metal spider 30 in the prior art, so that the weight is significantly reduced. It is possible to achieve simplification and simplification.
【０００９】[0009]
以上説明したように、本考案に係わる内燃機関用ファンによれば、従来技術に おけるインサートを省略したため、大幅な軽量化及び簡素化を達成することがで きる。 As described above, according to the internal combustion engine fan of the present invention, since the insert in the prior art is omitted, it is possible to achieve a significant weight reduction and simplification.
