【考案の詳細な説明】
この考案は主として車輛などの冷却ファンに用いられる
ファンブレードの取付は装置に関する。[Detailed Description of the Invention] This invention mainly relates to a device for attaching fan blades used in cooling fans of vehicles and the like.
従来この種の冷却ファンはファン本体を円筒状足形成し
て、その外周面に複数のファンブレードを固着具により
固着するか、星形に形成したファン本体の各突出部に固
着具によりファンブレードを固着した構造のものが比較
的多く採用されている。Conventionally, this type of cooling fan has either a fan body formed into a cylindrical leg and a plurality of fan blades fixed to the outer circumferential surface of the fan body using fixing devices, or fan blades attached to each protrusion of the star-shaped fan body using fixing devices. A relatively large number of structures have been adopted that have a fixed structure.
しかし前者の冷却ファンはブレードの取付は角が大きい
場合、取付は部の強度が不足することから、取付は部を
補強するため、ファン自体が重くなる欠点がある。However, in the case of the former type of cooling fan, if the blades are mounted at large corners, the strength of the mounting part is insufficient, and the fan itself has the disadvantage of being heavy because the mounting part has to be reinforced.
また後者の冷却ファンはブレードの取付は部が弱いため
、大径なファンやブレードの取付は角の大きいファンが
でき難い欠点があった。In addition, the blades of the latter type of cooling fan have a weak attachment point, making it difficult to install large-diameter fans or blades with large corners.
このような欠点を除去する目的で本出願人は先に円板状

スペーサを介して基端部に切欠を設けたブレードを増付
けるようにしたファンブレードの取付は装置を提案した
。In order to eliminate such drawbacks, the present applicant first provided a spacer having a surface for mounting the blades on a portion of the disk-shaped fan body, and a surface for mounting the blades at a corner, and We proposed a device for installing fan blades that includes an additional blade with a notch at the base end.
しかし、先に提案したものではファン本体にファンフレ
ードを突き合せ嵌合させて溶接したａであるから溶接欠
陥があると回転時に遠心力によって外方に飛び出してし
まうとの不具合を有する。However, in the previous proposal, since the fan blade is butt-fitted and welded to the fan body, there is a problem in that if there is a welding defect, the fan blade will fly out due to centrifugal force during rotation.
本考案は上記の事情に鑑みなされたものであり、そノ目
的はファンブレードとファン本体とを簡単に取付けるこ
とができると共に、ファン自体の重量軽減を計ることが
でき、さらには溶接欠陥等があっても遠心力でファンブ
レードが外方に飛び出すことがないようにしたファンブ
レードの取付ケ装置を提供することである。The present invention was developed in view of the above circumstances, and its purpose is to make it possible to easily attach the fan blades and the fan body, to reduce the weight of the fan itself, and to prevent welding defects. To provide a fan blade mounting device which prevents the fan blade from flying outward due to centrifugal force even if the fan blade is thrown out.
以下図面を参照して本考案の実施例を説明する。Embodiments of the present invention will be described below with reference to the drawings.
円板状のファン本体１の中央部には取付孔２が穿設しで
あると共に、取付溝３が周方向に等間隔で複数削設しで
ある。A mounting hole 2 is bored in the center of the disc-shaped fan main body 1, and a plurality of mounting grooves 3 are cut at equal intervals in the circumferential direction.
該取付溝３は周方向の基部切欠き４と直径方向の先部切
欠き５とから略Ｔ字型に形成しであると共に、先部切欠
き５０幅ｔはファン本体１の厚さｔ′よりも僅かに広く
なっている。The mounting groove 3 is formed into a substantially T-shape by a base notch 4 in the circumferential direction and a tip notch 5 in the diametrical direction, and the width t of the tip notch 50 is equal to the thickness t' of the fan body 1. It is slightly wider than the
一方、ファンブレード６０基部には取付用の開ロアが打
抜き形成してあり、該開ロアの長手方向幅すは前記先部
切欠き５の長さｂ′と同一で、端縁６ａとの距離ａは前
記基部切欠き４０幅ａ／と同一となっている。On the other hand, an open lower part for attachment is formed by punching at the base of the fan blade 60, and the longitudinal width of the open lower part is the same as the length b' of the tip notch 5, and the distance from the end edge 6a. a is the same as the base notch 40 width a/.
しかして、ファンブレード６を先端切欠き５かも基部切
欠き４に挿入する。Then, the fan blade 6 is inserted into the tip notch 5 and the base notch 4.
（第５図、第６図参照）
次に、ファンブレード６を第７図矢印方向に回転させて
開ロアを取付溝３０基部切欠き４０段部４ａに位置させ
てファンブレード６とファン本体１とを溶接して固着す
る。(See FIGS. 5 and 6) Next, rotate the fan blade 6 in the direction of the arrow in FIG. Weld and secure.
（第８図、第９図参照）以上のようであるからファンブ
レード６は開ロアが基部切欠き４の段部４ａに係合当接
して外方に引き抜くことができないので、溶接欠陥等が
あっても回転時に遠心力によってファンブレード６が飛
び出すことがない。(See Figures 8 and 9) As described above, the opening lower of the fan blade 6 engages and contacts the step 4a of the base notch 4 and cannot be pulled out outward, so welding defects etc. Even if there is, the fan blade 6 will not fly out due to centrifugal force during rotation.
本考案は以上の様になり、ファンブレード６の基部をフ
ァン本体１の取付溝３内に挿入し、ファンブレード６を
短手方向に回転させると開ロアが段部４ａに係合してフ
ァンブレード６がファン本体１に対して直径方向に抜は
出すことが防止されて取付けられる。The present invention is as described above, and when the base of the fan blade 6 is inserted into the mounting groove 3 of the fan body 1 and the fan blade 6 is rotated in the transverse direction, the open lower part engages with the stepped part 4a and the fan The blades 6 are attached to the fan body 1 while being prevented from being pulled out in the diametrical direction.
したがって、ファンブレード６を簡単にファン本体１に
取付けることができると共に、ファン自体の重量軽減を
計ることができ、さらには溶接欠陥等があっても遠心力
によってファンブレード６が外方に飛び出すことがない
。Therefore, the fan blades 6 can be easily attached to the fan body 1, the weight of the fan itself can be reduced, and even if there is a welding defect, the fan blades 6 will not fly out due to centrifugal force. There is no.
