Description

本発明は、ターボファンなどの送風ファンの取付構造に係わり、より詳しくは、モータ回転軸と回転止め座金の孔にＤカット状の平坦面を形成して、品質を向上させ、メンテナンスが容易にできる構造に関する。   The present invention relates to a mounting structure for a blower fan such as a turbo fan. More specifically, a D-cut flat surface is formed in a hole of a motor rotation shaft and a rotation washer to improve quality and facilitate maintenance. It relates to the structure that can be done.

従来のモータ回転軸への送風ファンの取付構造として、図５および図６に示すようなものが知られている（例えば、特許文献１参照。）。   As a conventional attachment structure of a blower fan to a motor rotation shaft, one shown in FIGS. 5 and 6 is known (see, for example, Patent Document 1).

図５に示すように、送風ファン３’のハブ３ｂ’の中心部にモータ４’の駆動軸４ａ’が直結されており、モータ４’の駆動に伴って送風ファン３’が回転するようになっている。送風ファン３’のハブ３ｂ’は、その中央部分が下側に凹陥され、この中央部分の上側にモータ４’を収容するための空間Ａ’を形成している。   As shown in FIG. 5, the drive shaft 4a ′ of the motor 4 ′ is directly connected to the center of the hub 3b ′ of the blower fan 3 ′ so that the blower fan 3 ′ rotates as the motor 4 ′ is driven. It has become. The hub 3b 'of the blower fan 3' has a central portion recessed downward, and a space A 'for accommodating the motor 4' is formed above the central portion.

そして、このハブ３ｂ’の中心部には、貫通孔３ｅ’が上下方向に貫通形成されており、この貫通孔３ｅ’にモータ４’の駆動軸４ａ’が上方から挿通されている。この駆動軸４ａ’の長さ寸法は、ハブ３ｂ’の板厚寸法よりも大きく、このため、該駆動軸４ａ’の先端部分は、ハブ３ｂ’の下側に突出された状態となっている。   A through hole 3e 'is formed in the center portion of the hub 3b' in the vertical direction, and the drive shaft 4a 'of the motor 4' is inserted from above into the through hole 3e '. The length dimension of the drive shaft 4a ′ is larger than the plate thickness dimension of the hub 3b ′. For this reason, the tip end portion of the drive shaft 4a ′ is in a state of protruding below the hub 3b ′. .

そして、このハブ３ｂ’の下側に位置する駆動軸４ａ’の先端部分には、ハブ３ｂ’をモータ４’の駆動軸４ａ’に対して回転一体に取付けるための支持部材としてのボス部材１５’が装着されている。   A boss member 15 as a support member for rotatably attaching the hub 3b ′ to the drive shaft 4a ′ of the motor 4 ′ at the tip end portion of the drive shaft 4a ′ positioned below the hub 3b ′. 'Is installed.

また、図６に示すように、樹脂の一体成形品で成る支持部材としての絶縁ナット２０’を使用している。送風ファン３’のハブ３ｂ’は、その中心部に比較的大径の円筒状のボス部３ｇ’が一体形成されており、このボス部３ｇ’の内部には中心部に上下方向に延びる貫通孔２１ａ’を備えたブッシュ２１’が充填されている。また、このブッシュ２１’の貫通孔２１ａ’に、外周面にオネジが形成されたモータ４’の駆動軸４ａ’が挿通されている。また、この駆動軸４ａ’は、その一部が上下方向に亘って平坦面となる所謂Ｄカット状にされている。また、このブッシュ２１’の下面には後述する回転止め座金２２’の係止爪２２ｂ’が係止される複数の係止溝２１ｂ’が形成されている。   Further, as shown in FIG. 6, an insulating nut 20 'is used as a support member made of an integrally molded product of resin. A hub 3b ′ of the blower fan 3 ′ is integrally formed with a cylindrical boss 3g ′ having a relatively large diameter at the center, and the boss 3g ′ has a through-hole extending vertically in the center. A bushing 21 ′ having a hole 21a ′ is filled. The drive shaft 4a 'of the motor 4' having a male screw formed on the outer peripheral surface is inserted into the through hole 21a 'of the bush 21'. The drive shaft 4a 'has a so-called D-cut shape, a part of which is a flat surface in the vertical direction. A plurality of locking grooves 21b 'for locking locking claws 22b' of a rotation stopper washer 22 'to be described later are formed on the lower surface of the bush 21'.

そして、絶縁ナット２０’は、ブッシュ２１’との間に回転止め座金２２’が介在された状態で駆動軸４ａ’に螺着されている。この回転止め座金２２’は、中心部に上記駆動軸４ａ’の形状に対応したＤカット状の貫通孔２２ａ’を備え、その外周面には上方に折り曲げられて成る複数の係止爪２２ｂ’が備えられている。そして、この貫通孔２２ａ’に駆動軸４ａ’を挿通した状態において係止爪２２ｂ’をブッシュ２１’下面の係止溝２１ｂ’に係合することにより、駆動軸４ａ’とハブ３ｂ’とが回転一体とされている。   The insulating nut 20 ′ is screwed to the drive shaft 4 a ′ with a rotation washer 22 ′ interposed between the insulating nut 20 ′ and the bush 21 ′. The rotation stopper washer 22 ′ is provided with a D-cut through hole 22a ′ corresponding to the shape of the drive shaft 4a ′ at the center, and a plurality of locking claws 22b ′ formed by bending upward on the outer peripheral surface thereof. Is provided. Then, the engaging claw 22b ′ is engaged with the engaging groove 21b ′ on the lower surface of the bush 21 ′ while the driving shaft 4a ′ is inserted into the through hole 22a ′, so that the driving shaft 4a ′ and the hub 3b ′ are engaged. Rotation is integrated.

しかしながら、上記取付構造の場合、駆動軸４ａ’のオネジ部分にＤカットが施されているため、このオネジ部分にバリが発生し、駆動軸４ａ’に絶縁ナット２０’を螺着する際、ネジ山のつぶれ等が生じ絶縁ナット２０’を確実に固定できないという問題がある。また、このバリを切除する場合には手間が掛かりコストアップとなってしまう。
特許第３１８０５７６号公報（３〜４頁、図２、図９） However, in the case of the above mounting structure, since the male screw portion of the drive shaft 4a ′ is D-cut, burrs are generated in this male screw portion, and when the insulating nut 20 ′ is screwed to the drive shaft 4a ′, the screw There is a problem that the insulating nut 20 'cannot be fixed reliably due to crushing of the mountain. Further, when this burr is excised, it takes time and costs are increased.
