〔産業上の利用分野〕
本発明はエンジンを始動するためのスタータ等に用いら
れる一方向性クラッチに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a one-way clutch used in a starter or the like for starting an engine.
従来、この種のクラッチにおいては、内周に複数のカム
室を有するタラソチアウタを、合金鋼を冷鍛加工するこ
とにより形成するのが一般的であるが、カム室形状が複
雑で精度のよい成形が要求されるため、加工が難しく、
かつ重量が重いという欠点があった。Conventionally, in this type of clutch, the thalassocia outer, which has multiple cam chambers on the inner periphery, is generally formed by cold forging alloy steel, but the cam chamber shape is complex and requires precise forming. is difficult to process as it requires
It also had the disadvantage of being heavy.
また、タラソチアウタを複数に分割して成形することも
考えられているが（例えば実開昭５８−５３９２８号公
報）、まだ、充分とは言えなかった。It has also been considered to divide the thalassocia outer into a plurality of pieces and mold them (for example, Japanese Utility Model Application Publication No. 58-53928), but this method has not yet been sufficient.
そこで、本発明は、形成が容易で軽量化できることを目
的とする。Therefore, an object of the present invention is to facilitate formation and reduce weight.
そのため本発明は、クラッチインナと、このインナの外
周に配置され、内周側に複数のカム室を有する樹脂製の
アウタと、このアウタの各カム室内周に配置される複数
のローラ当たり面を前記アウタと一体的に形成したカム
用鉄板と、前記カム室内に収納されたクラッチローラと
、前記アウタの外周に圧入嵌合されたクラッチカバーと
を備える一方向性クラッチを提供するものである。Therefore, the present invention includes a clutch inner, a resin outer that is arranged on the outer periphery of the inner and has a plurality of cam chambers on the inner periphery, and a plurality of roller contact surfaces arranged on the periphery of each cam chamber of the outer. A one-way clutch is provided that includes a cam iron plate integrally formed with the outer, a clutch roller housed in the cam chamber, and a clutch cover press-fitted to the outer periphery of the outer.
これにより、カム室も樹脂の成形および鉄板の折り曲げ
により、容易に成形でき、かつ重量の軽い樹脂の使用が
可能となる。As a result, the cam chamber can be easily formed by molding resin and bending an iron plate, and lightweight resin can be used.
以下本発明を図に示す実施例について説明する。 The present invention will be described below with reference to embodiments shown in the drawings.
第１図乃至第５図において、１はクラッチローラ、２は
円板状のカム用鉄板で、その外周側には複数のカム室５
のローラ当たり面を形成する傾斜した円弧曲面状の板辺
２ａが等間隔で屈曲形成しである。３はアウタで、高強

内周に一体成形されている。４はクラッチインナ、５は
クラッチのカム室で、鉄板２とインナ４とで構成される
楔部分からなる。６はモータ９のアーマチャシャフトで
、このシャフト６上に構成されたスプライン上とクラブ
チアウタ３が摺動可能に係合している。In FIGS. 1 to 5, 1 is a clutch roller, 2 is a disc-shaped cam iron plate, and a plurality of cam chambers 5 are provided on the outer circumferential side thereof.
The plate sides 2a, which are in the form of inclined arcuate surfaces forming roller contact surfaces, are bent at equal intervals. 3 is an outer molded with high-strength resin, and the cam iron plate 2 is integrally molded on the inner periphery of the outer 3. 4 is a clutch inner, and 5 is a cam chamber of the clutch, which consists of a wedge portion made up of an iron plate 2 and an inner 4. Reference numeral 6 denotes an armature shaft of the motor 9, and the club chire outer 3 is slidably engaged with a spline formed on the shaft 6.
７はクラッチ側スプラインで、アウタ３と同じく一体に
樹脂成形されている。８は鉄板を絞り加工してなるクラ
ッチカバーで、アウタ３の外周に圧入嵌合されている。7 is a clutch side spline, which is integrally molded with resin like the outer 3. Reference numeral 8 denotes a clutch cover formed by drawing an iron plate, and is press-fitted onto the outer periphery of the outer 3.
１０はクラッチインナ４と一体的に形成されたピニオン
で、マグネットスイッチ１１により軸方向に押出されて
エンジンのりングギャと噛み合うようにしである。１２
はローラ１をカム室５の幅狭方向に押圧するためにカム
室５内に収納したスプリングである。A pinion 10 is formed integrally with the clutch inner 4, and is pushed out in the axial direction by a magnetic switch 11 so as to mesh with a ring gear of the engine. 12
is a spring housed in the cam chamber 5 to press the roller 1 in the narrow direction of the cam chamber 5.
クラッチはモータ９のトルクをエンジンに伝達するため
、負荷トルクに負けない強度を必要とし、このため従来
はクラッチの構造体に樹脂を使用することが出来なかっ
た。しかし近年、高強度の樹脂が開発され、低負荷のス
タータでは樹脂をクラッチに使用出来る様になって来た
。本発明は前記背景のもとに、さらに負荷トルクの高い
スタータに通用出来ることを狙っている。Since the clutch transmits the torque of the motor 9 to the engine, it needs to be strong enough to withstand the load torque, and for this reason conventionally it has been impossible to use resin for the structure of the clutch. However, in recent years, high-strength resins have been developed, and it has become possible to use resins for clutches in low-load starters. Based on the above background, the present invention aims to be applicable to starters with a higher load torque.
スタータのトルクが増して来るとローラ１とアウタ３と
の間の面圧が高くなり、樹脂ではこの面圧に耐えること
が出来ない。そこで、カム室５のローラ当り面を鉄板２
とし樹脂アウタ３と一体で成形することで、この面圧に
対処する。又、高トルクでのアウタ３の拡がりと曲げ荷
重に対しては、鉄板を絞って形成したクラッチカバー８
をアウタ３の外周に圧入嵌合して、この補強としている
。As the torque of the starter increases, the surface pressure between the roller 1 and the outer 3 increases, and the resin cannot withstand this surface pressure. Therefore, the roller contact surface of the cam chamber 5 was placed on an iron plate 2.
This surface pressure can be coped with by integrally molding it with the resin outer 3. In addition, in order to withstand the expansion and bending load of the outer 3 due to high torque, the clutch cover 8 is formed by squeezing a steel plate.
is press-fitted to the outer periphery of the outer 3 to reinforce it.
以上の構成とすることにより、樹脂のもつ強度上の不利
に対処でき、軽量のクラッチとすることが出来る。一方
、クラッチのスプライン７はアウタ３を構成する樹脂と
一体で成形されており、強度上従来の鉄のスプラインに
比べ長くはなるものの、軽量で、しかも加工が容易であ
る。With the above structure, the disadvantages of resin in terms of strength can be overcome, and a lightweight clutch can be obtained. On the other hand, the spline 7 of the clutch is molded integrally with the resin constituting the outer 3, and although it is longer than conventional iron splines in terms of strength, it is lightweight and easy to process.
本実施例ではスプライン７とアウタ３を樹脂で一体に成
形しているが、分離して材質を変えても可能である。In this embodiment, the spline 7 and the outer 3 are integrally molded from resin, but they may be separated and made of different materials.
以上述べたように本発明においては、クラブチアウタの
カム室を樹脂の成形および鉄板により容易に形成できる
から、成形および加工が容易にできると共に、重量の軽
い樹脂の使用が可能となって、軽量化できるのみならず
、ローラ当たり面の鉄板とクラッチカバーとによって強
度上も十分に耐え得るものが得られるという優れた効果
がある。As described above, in the present invention, since the cam chamber of the club chia outer can be easily formed by molding resin and using a steel plate, molding and processing are easy, and lightweight resin can be used, resulting in weight reduction. Not only is this possible, but it also has the excellent effect of providing sufficient strength and durability due to the iron plate on the roller contact surface and the clutch cover.
