Description
【０００１】[0001]
この考案は、樹脂製ギヤ等の樹脂部品を軸部材にキ−溝により回転不能に固定 する構造に関するものである。 The present invention relates to a structure in which a resin component such as a resin gear is non-rotatably fixed to a shaft member by a key groove.
【０００２】[0002]
軸部材に嵌入する部品をキ−溝で固定する構造は実公昭５０−１４０５８号公 報に示すように、軸部材に被固定部材である部品を嵌入して軸部材に設けたキ− 溝にキ−を挿入する構造が一般的であるが、実開昭６２−１９９５１５号公報の ように被固定部材にキ−を一体成形したもの等種々な構造が採用されている。 As shown in Japanese Utility Model Publication No. 50-14058, a structure in which a part to be fitted into a shaft member is fixed in a key groove is as follows. Although a structure for inserting a key is generally used, various structures such as a structure in which a key is integrally formed with a fixed member as in Japanese Utility Model Laid-Open No. 62-199515 are adopted.

しかし、上記の前者の従来構造においては、組付時にキ−が脱落したりして組 付作業性が悪い。 これに対して後者の固定構造は組付作業性が良くしかも部品 点数も少ないという利点はあるが、キ−溝が軸部材の端部に形成されている場合 に限られ、軸部材の途中にキ−溝がある場合には適用できないという欠点がある 。 この考案は以上のような問題を解決することを目的とするものである。 However, in the former conventional structure described above, the assembling workability is poor because the key may fall off during assembly. On the other hand, the latter fixing structure has the advantages of good workability in assembling and a small number of parts, but only when the key groove is formed at the end of the shaft member. It has a drawback that it cannot be applied when there is a key groove. The present invention is intended to solve the above problems.

この考案は、上記目的を達成するために軸部材に嵌入する樹脂部品を軸部材に 設けたキ−溝により回転不能に固定する構造において、前記樹脂部品の嵌入孔の 内面に軸方向に延びる凹溝を設けると共に、この凹溝と前記軸部材のキ−溝の双 方に嵌合するキ−を設け、このキ−と前記樹脂部品とを薄肉部を介して一体に成 形ものである。 In order to achieve the above object, the present invention has a structure in which a resin component fitted into a shaft member is non-rotatably fixed by a key groove provided in the shaft member, and a recess extending in the axial direction is formed in the inner surface of the fitting hole of the resin component. A groove is provided, and a key that fits in both directions of the concave groove and the key groove of the shaft member is provided. The key and the resin component are integrally formed via a thin portion.

上記の構成によれば、キ−は薄肉部を中心にして回動することができので、樹 脂部品を軸端から軸部材に嵌入するときは、キ−は邪魔にならない様に嵌入孔の 外方に回動させておき、キ−溝位置まで嵌入したときにキ−を内側に回動させて キ−溝と凹溝の双方にキ−を嵌合すると、軸部材に樹脂部品が回転不能に固定さ れる。このとき、キ−と樹脂部品とは一体となっているので、キ−が途中で脱落 することもなく迅速に組付けられる。 According to the above configuration, since the key can be rotated around the thin portion, when the resin part is inserted into the shaft member from the shaft end, the key is provided with the insertion hole so as not to get in the way. When the key is fitted to both the key groove and the groove by turning it outward and turning the key inward when it is fitted to the key groove position, the resin part rotates on the shaft member. It is fixed to be impossible. At this time, since the key and the resin part are integrated, the key does not drop out on the way and can be quickly assembled.

この考案でいう樹脂部品とは、全体が樹脂で構成されているものに限らず少な くとも軸部材への嵌入部が樹脂で構成されているものをいう。 以下 自動車の スピ−ドメ−タギアの固定構造に適用した場合の実施例について説明する。 図１はスピ−ドメ−タギア取付部の断面図、図２は図１のＡ−Ａ断面図、図３ はスピ−ドメ−タギアの断面図である。 図において、１はケ−ス２にベアリング３を介して軸受支持された変速機の出 力軸、４はケ−ス２から突出する出力軸１の軸端を締め上げるロックナットであ り、このロックナット４はその薄肉筒部４ａの局部を内側に変形して出力軸１に 形成したキ−溝５内に嵌入することによりロックナットの緩み止めをしている。 ６はロックナット４に隣接して出力軸１に回転不能に固定されるスピ−ドメ− タドライブギアであり、これに直交するスピ−ドメ−タドリブンギア７を駆動し 、図示しないケ−ブルを介してスピ−ドメ−タに回転力を伝達する。 The resin component referred to in the present invention is not limited to the one entirely made of resin, but at least the fitting portion to the shaft member is made of resin. An embodiment of the invention applied to a fixed structure of a speedometer gear of an automobile will be described below. 1 is a sectional view of the speedometer gear mounting portion, FIG. 2 is a sectional view taken along the line AA of FIG. 1, and FIG. 3 is a sectional view of the speedometer gear. In the drawing, 1 is an output shaft of a transmission bearing-supported by a case 2 through a bearing 3, and 4 is a lock nut for tightening the shaft end of an output shaft 1 protruding from the case 2. The lock nut 4 prevents the lock nut from loosening by deforming the local portion of the thin-walled cylinder portion 4a inward and fitting it into a key groove 5 formed in the output shaft 1. 6 is a speed meter drive gear which is fixed to the output shaft 1 so as not to rotate adjacent to the lock nut 4, drives a speed meter driven gear 7 orthogonal to this, and through a cable (not shown). To transmit the rotational force to the speed meter.
【０００７】 上記のスピ−ドメ−タドライブギア６は、樹脂にて構成されており、図３に示 すように外周にギア部８を有し、出力軸１に嵌入する嵌入孔９の内面にはキ−溝 ５に対応する凹溝１０が設けられている。また、スピ−ドメ−タドライブギア６ の端面と凹溝１０との交差部にはキ−１１が薄肉部１２を介して一体に成形され ている。このキ−１１は、略扇型の形状をしてその要部分が薄肉部１２を介して スピ−ドメ−タドライブギア６と繋がっており、この薄肉部を中心にして回動可 能とされ、内側に回すと図３の（Ｂ）に示すように凹溝１０に嵌合するようにな されている。 出力軸１にスピ−ドメ−タドライブギア６を組付けるときは、図３の（Ａ）に 示すようにキ−１１を外側に回して嵌入孔に出力軸１を挿入し、キ−溝５の位置 まで挿入された時点でキ−１１を内側に回すと、キ−１１は図１、図２の様にキ −溝５と凹溝１０の双方に嵌合しスピ−ドメ−タドライブギア６が出力軸１に対 して回転不能に固定される。 なお、１３はスピ−ドメ−タドライブギア６の軸 方向位置を規制するストッパリングである。 また、キ−の形状は扇型でなくても良いとともに、スピ−ドメ−タギアのどち ら側の端面に設けても良い。さらに、薄肉部はキ−の組付け後に破断するもので あっても良い。The speed meter drive gear 6 is made of resin, has a gear portion 8 on the outer periphery as shown in FIG. 3, and has an inner surface of a fitting hole 9 fitted into the output shaft 1. A groove 10 corresponding to the key groove 5 is provided in the. A key 11 is integrally formed at the intersection of the end surface of the speedometer drive gear 6 and the groove 10 with a thin portion 12 interposed therebetween. The key 11 has a substantially fan shape, and its main portion is connected to the speedometer drive gear 6 through the thin portion 12, and is rotatable about the thin portion. When turned inward, it fits into the groove 10 as shown in FIG. 3 (B). When assembling the speed meter drive gear 6 to the output shaft 1, as shown in FIG. 3 (A), the key 11 is turned outward to insert the output shaft 1 into the fitting hole, and then the key groove 5 is inserted. When the key 11 is turned inward at the time when it is inserted to the position, the key 11 is fitted in both the key groove 5 and the concave groove 10 as shown in FIGS. 1 and 2, and the speed meter drive gear. 6 is fixed to the output shaft 1 so as not to rotate. Reference numeral 13 is a stopper ring that regulates the axial position of the speed meter drive gear 6. The shape of the key does not have to be fan-shaped, and it may be provided on either side of the speedometer gear. Further, the thin portion may be broken after the key is assembled.

この考案によれば、キ−と被固定部材であ樹脂部品が薄肉部を介して回動可能 に一体化されているので、軸部材の途中にキ−溝がある場合でも支障なく組付け ることができるとともに、組付け時にキ−が脱落するとがないので、迅速に組付 けられ、さらに部品点数削減によるコスト低減を図ることができる。 According to this invention, since the key and the resin component, which is the fixed member, are rotatably integrated through the thin portion, even if there is a key groove in the middle of the shaft member, it can be assembled without any trouble. In addition, since the key does not fall off during assembly, the assembly can be done quickly, and the cost can be reduced by reducing the number of parts.
