弾性部材は、熱可塑性樹脂製の中間筒部を介してボス部にモールドされるとと もに、熱可塑性樹脂製のインサート環を介して取付環にモールド成形したので、 弾性部材の中間筒部と取付環に対する馴染みがよく、固定力が向上する。 このため、作業効率が著しく向上し、量産性に優れることはもちろん、回転装 置の稼働時に、ボス部から弾性部材および取付環を介して翼片へ回転力が伝達さ れたり、変速が伝達されたりして弾性部材がトルクを受けて変形力を受けても、 この変形力によりボス部と取付環に対する弾性部材の固着力が殺がれて弾性部材 の変形が起こることがなくなり、大幅な耐久性の向上が期待される。 また、具体的な回転装置用吸震形ボスによれば、鋸歯状部はルーレット（ロー レット）加工により形成され、ボス部からの回転トルクが支障なく弾性部材側に 確実に伝達されるようにしている。 さらに、他の回転装置用吸震形ボスによれば、ボス部はアルミニウムにより形 成され、軽量化が図られている。 加えて、他の回転装置用吸震形ボスによれば、中間筒部およびインサート環は 、共にポリプロピレンにガラスを加えて成形してガラス強化樹脂により形成され 、所定の強度および剛性を確保している。 The elastic member is molded on the boss through the thermoplastic intermediate cylinder, and at the same time, it is molded on the mounting ring through the thermoplastic resin insert ring.

以下、本考案の実施例を図面に基づいて説明する。 まず、本考案の実施例を示す図１および図２において、この実施例は本考案に 係る回転装置用吸震形ボスを送風機１に組み込んだもので、モータ２の回転軸２ ａには、金属例えばアルミニウム製の筒型ボス部３が嵌め込まれ、ボルト４によ り回転軸２ａに固定されている。筒型ボス部３の先端表面には、ルーレット（ロ ーレット）あるいはセレーションからなる回り止め用の鋸歯状部５が形成されて いる。このボス部３の鋸歯状部５には、熱可塑性樹脂製の中間筒部６を一体的に モールド成形している。この中間筒部６は、本実施例ではポリプロピレンに２０ 重量％のガラスを加えて成形してガラス強化樹脂により形成されている。 さて、外周縁部に複数の翼片１１が等角度間隔に取り付けられる金属製の取付 環７を配して、この取付環７の内周縁部７ａの全周に断面コ字型の熱可塑性樹脂 製のインサート環８を一体的にモールド成形して取付部９を形成している。この インサート環８が内部に埋設されるように取付環７にわたって、熱可塑性樹脂製 の弾性部材たる吸震用ゴム１０をモールド成形により設けている。この吸震用ゴ ム１０の材質としては、ＮＢＲをはじめＢＲ、ＳＢＲ、ＣＲ、ＩＲ、ＩＩＲ、Ｅ ＰＲあるいはＥＰＤＲなどが適用できる。 しかして、送風機１の運転にあたっては、モータ２への通電により、回転軸２ ａを介してボス部３が駆動されて、中間筒部６、吸震用ゴム１０および取付部９ を介して翼片１１に回転が伝達されて所定の方向に送風される。この時、モータ ２側が震動により揺れても、この揺れは吸震用ゴム１０により効果的に吸収され るので、翼片１１への揺れの影響が少なくなり、送風効率の変動や送風方向が変 更されることなく、略一定に維持される。 このような回転装置用吸震形ボスは下記の工程により製造される。 （１）まず、図３に示す如く、筒型ボス部３の先端表面に回り止め用の鋸歯状部 ５を形成する。 （２）ついで、図４に示す如く、このボス部３の鋸歯状部５に熱可塑性樹脂製の 中間筒部６を一体的にモールド成形する。 （３）図５に示す如く、金属製の取付環７を配して、この取付環７の内周縁部７ ａの全周に断面コ字型の熱可塑性樹脂製のインサート環８を一体的にモールド成 形して取付部９を形成する。 （４）つぎに、図６に示す如く、取付部９を中間筒部６の周りに同心的に配置し 、該中間筒部６からインサート環８が内部に埋設されるように、取付環７にわた って熱可塑性樹脂製の弾性部材たる吸震用ゴム１０をモールド成形する。 このモールド成形工程時の型締力は１００Kg／cm2 から２００Kg／cm2 位の範 囲内に設定されているが、吸震用ゴム１０のインサート環８に対する吸着親和力 が良好なため、吸震用ゴム１０の取付環７の両側面に対する密着性が向上し、吸 震用ゴム１０の外周縁部１０ａが取付環７に確実に接合維持される。 以上の工程により、回転装置用吸震形ボスが形成されるものであるが、ボス部 ３の鋸歯状部５に熱可塑性樹脂製の中間筒部６を形成するとともに、取付環７の 内周縁部７ａに熱可塑性樹脂製のインサート環８を形成したので、吸震用ゴム１ ０は、中間筒部６およびインサート環８に対する馴染み性が強くなって、これら 中間筒部６およびインサート環８を介してボス部３および取付部９に確実に固着 する。よって、作業効率が著しく向上し、量産性に優れることはもちろん、回転 装置の稼働時に、ボス部３から吸震用ゴム１０および取付環７を介して翼片１１ へ回転力が伝達されたり、変速が伝達されたりして吸震用ゴム１０が不用意にト ルクを受けて変形力を受けても、この変形力によりボス部３と取付環７に対する 吸震用ゴム１０の固着力が殺がれてゴム１０の変形が起こることがなくなり、耐 久性の大幅な向上が期待される。Embodiments of the present invention will be described below with reference to the drawings. First, referring to FIGS. 1 and 2 showing an embodiment of the present invention, in this embodiment, a vibration absorbing boss for a rotating device according to the present invention is incorporated into a blower 1, and a metal is attached to a rotary shaft 2a of a motor 2. For example, a tubular boss portion 3 made of aluminum is fitted and is fixed to the rotary shaft 2a by a bolt 4. On the tip surface of the cylindrical boss portion 3, there is formed a serrated portion 5 made of roulette or serration for stopping rotation. The serrated portion 5 of the boss portion 3 is integrally molded with an intermediate tubular portion 6 made of a thermoplastic resin. In this embodiment, the intermediate tubular portion 6 is formed of glass reinforced resin by molding by adding 20% by weight of glass to polypropylene. Now, a metal mounting ring 7 to which a plurality of wing pieces 11 are mounted at equal angular intervals is arranged on the outer peripheral edge portion, and a thermoplastic resin having a U-shaped cross section is provided on the entire circumference of the inner peripheral edge portion 7a of the mounting ring 7. The mounting ring 9 is formed by integrally molding the insert ring 8 made of aluminum. A vibration absorbing rubber 10 which is an elastic member made of a thermoplastic resin is provided by molding over the mounting ring 7 so that the insert ring 8 is embedded inside. As the material of the vibration absorbing rubber 10, NBR, BR, SBR, CR, IR, IIR, EPR, EPDR, or the like can be applied. Therefore, when the blower 1 is operated, the boss 3 is driven via the rotating shaft 2 a by energizing the motor 2, and the wing piece 3 is driven via the intermediate cylinder 6, the vibration absorbing rubber 10 and the mounting 9. The rotation is transmitted to 11 and is blown in a predetermined direction. At this time, even if the motor 2 side shakes due to a vibration, this shaking is effectively absorbed by the rubber 10 for absorbing the vibration, so that the influence of the shake on the blade 11 is reduced, and the change in the blowing efficiency and the blowing direction are changed. It is maintained almost constant without being performed. Such a vibration absorbing boss for a rotating device is manufactured by the following steps. (1) First, as shown in FIG. 3, a serrated portion 5 for preventing rotation is formed on the tip surface of the cylindrical boss portion 3. (2) Then, as shown in FIG. 4, the intermediate cylindrical portion 6 made of thermoplastic resin is integrally molded on the serrated portion 5 of the boss portion 3. (3) As shown in FIG. 5, a mounting ring 7 made of metal is arranged, and an insert ring 8 made of a thermoplastic resin having a U-shaped cross section is integrally formed on the entire circumference of the inner peripheral edge portion 7 a of the mounting ring 7. Then, the mounting portion 9 is formed by molding. (4) Next, as shown in FIG. 6, the mounting portion 9 is concentrically arranged around the intermediate cylindrical portion 6, and the mounting ring 7 is inserted from the intermediate cylindrical portion 6 so that the insert ring 8 is embedded therein. A rubber 10 for absorbing vibration, which is an elastic member made of a thermoplastic resin, is molded over the entire surface. The mold clamping force during this molding process is set within the range of about 100 kg / cm 2 to 200 kg / cm 2, but since the absorption rubber 10 has a good adsorption affinity for the insert ring 8, the absorption rubber 10 The adhesion to both side surfaces of the mounting ring 7 is improved, and the outer peripheral edge portion 10a of the rubber 10 for vibration absorption is reliably joined and maintained to the mounting ring 7. By the above steps, the vibration absorbing boss for the rotating device is formed. The intermediate cylindrical portion 6 made of thermoplastic resin is formed on the serrated portion 5 of the boss portion 3, and the inner peripheral edge portion of the mounting ring 7 is formed. Since the insert ring 8 made of a thermoplastic resin is formed on the 7a, the vibration absorbing rubber 10 becomes more familiar to the intermediate tubular portion 6 and the insert ring 8, and the intermediate tubular portion 6 and the insert ring 8 are interposed. Securely adhere to the boss portion 3 and the mounting portion 9. Therefore, not only the working efficiency is remarkably improved and the mass productivity is excellent, but also when the rotating device is in operation, the rotational force is transmitted from the boss portion 3 to the wing piece 11 via the vibration absorbing rubber 10 and the mounting ring 7, and the gear shifting is performed. Even if the seismic absorption rubber 10 is inadvertently subjected to a torque and receives a deforming force, this deforming force kills the fixing force of the seismic absorbing rubber 10 to the boss portion 3 and the mounting ring 7. Deformation of the rubber 10 will not occur, and it is expected that the durability will be greatly improved.
