本発明はオーバーランニングクラッチに係り、特に内燃

ーバーランニングクラッチに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an overrunning clutch, and more particularly to an overrunning clutch suitable for a one-way clutch for a starter for starting an internal combustion engine.
従来のオーバーランニングクラッチは、実公昭６１−５

り絞り込んで固定している。The conventional overrunning clutch was developed in 1986-5.
As described in Publication No. 56, a clutch inner with a pinion is inserted through a roller into an outer cover having an open end, and an annular presser plate is arranged at the open end, and then an outer cover made of a steel plate is placed around the clutch outer. Usually, the outer cover is a cylindrical body with one side as a bottom material, and after being inserted from the open end side, the opposite end side is narrowed by curling or the like and fixed.
従来技術はオーバーランニングクラッチの軽量化につい
て配慮されておらず、結果的にはスタータの全重量を上
げていた。The conventional technology did not consider reducing the weight of the overrunning clutch, and as a result, the overall weight of the starter increased.

て前記波がりに備えている。従ってクラッチアウターは
単品部品でみると非常に重くなってしまう欠点があり、
省資源の観点から軽量化が望まれているに対し不利であ
った。That is, since the overrunning clutch rotates at high speed in synchronization with the rotation of the starter motor, centrifugal force is applied to the open end side of the clutch outer, and a force that tends to spread acts on the open end side of the clutch outer. Since this expansion disrupts the concentricity between the clutch inner and the clutch outer and reduces the function of the clutch, the plate thickness of the outer peripheral part of the clutch outer is generally increased to prepare for the undulation. Therefore, the clutch outer has the disadvantage that it is extremely heavy when viewed as a single component.
This was disadvantageous since weight reduction was desired from the viewpoint of resource conservation.
本発明の目的は、クラッチアウターの外周部の肉厚を薄
くして軽量化を図れ、精度の高い構造のオーバーランニ
ングクラッチを提供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide an overrunning clutch that is lightweight by reducing the thickness of the outer circumference of the clutch outer and has a highly precise structure.
上記目的は、クラッチアウターの開口端に断回路り字状

達成される。The above purpose is to fit a clutch cover made of a rigid annular body in the shape of a disconnected cursor into the open end of the clutch outer, and to fit the annular unevenness formed on the inner circumferential surface of the clutch cover or the outer circumferential surface of the clutch outer. This is achieved by connecting one of the corresponding members to be locally plastically deformed.

ッチアウターの肉厚を薄くしてもクラッチローラの動き
を確実にすることができる。The clutch cover, which is made of a rigid annular body, prevents the opening end of the clutch outer from expanding in the radial direction due to centrifugal force when the clutch rotates, and maintains a constant distance between the clutch outer and clutch inner, thereby preventing the clutch from expanding in the radial direction due to centrifugal force. Even if the outer wall thickness is made thinner, the movement of the clutch roller can be ensured.
実施例 本発明の実施例を図により説明する。Example Embodiments of the present invention will be described with reference to the drawings.
第４図は本発明になるオーバーランニングクラッチを備

転しそのトルクは軸３と一体に形成された電機子ピニオ
ン４に伝達される。In FIG. 4, an armature 2 of a motor 1 rotates around a shaft 3, and its torque is transmitted to an armature pinion 4 formed integrally with the shaft 3.

った状態にして遊星歯車装置を構成する。The armature pinion 4 constitutes the central sun gear of the planetary gear arrangement, whereas the internal ring gear 6 constitutes the outer sun gear. In the annular space 5 formed between the armature pinion 4 and the internal ring gear 6, a plurality of planetary gears 7, for example, three planetary gears 7, are arranged at equal intervals and meshed with each other. This constitutes a planetary gear system.

きるように成っている。The overrunning clutch 13 that transmits the power of the starter in one direction includes a roller 14, a clutch outer 15, a clutch inner 16, a pinion 17 formed integrally with the inner, a washer 18 for regulating the axial movement of the roller, and the clutch. It mainly consists of a cover 19. The clutch outer 15 is engaged with a helical spline 2o provided on the pinion shaft 1o, so that it can be moved on the pinion shaft.

。Next, the overrunning clutch 1 which is the gist of the present invention

り結合を保っている。In the figure, an annular unevenness (S) 15 b is previously formed on the outer periphery of the clutch outer 15 on the open end side. A clutch cover 19 made of a highly rigid annular body (specifically, hardened steel) is fitted onto the side surface of the opening end, as shown in FIG. 3 in detail.
By locally pressing the entire circumference of the inner diameter portion in the axial direction, a part of the clutch cover member is plastically deformed vertically toward the radial uneven portion 15b, thereby coupling the two. In this bonded state, the plastically deformed member comes into close contact with the uneven portion, increasing tension, and the bond is maintained by the shearing force of the plastically deformed portion.
尚、第３図に示す如くクラッチアウタ−１５の外周部を

性変形させても同様の効果が期待出来る。Incidentally, as shown in FIG. 3, the same effect can be expected even if the outer peripheral portion of the clutch outer 15 is plastically deformed toward the annular unevenness 19a provided on the clutch cover 19 side.

伝えられ、ピニオン軸１０へと伝達される。When power is supplied to this starter as explained above, armature 2
generates torque and the armature shaft 3 rotates. That is armature pinion 4. The signal is transmitted to the planetary arm 9 at a predetermined reduction ratio through a planetary gear device consisting of a 6° internal ring gear and a planetary gear 7, and is then transmitted to the pinion shaft 10.

始動することになる。This rotation of the pinion shaft 10 is caused by the helical spline 2
0 is transmitted to the clutch outer 15 which engages with the clutch outer 15. At this time, when the electromagnetic solenoid 22 operates, the shift lever 23 pushes the roller clutch 13, and the thrust of the helical spline moves the pinion 17 to the right in the figure, which meshes with the ring gear of the internal combustion engine (not shown) and starts the engine. become.

なくともよいことになりオーバーランニングクラッチの
小形軽量化が実現出来る。When transmitting the rotation mentioned above, the clutch outer 15 is of course the same as before.
Centrifugal force acts on the opening, but since the open end is held by a highly rigid annular body, it does not expand and deform in the radial direction.
Since the distance between the clutch outer and inner clutch is always kept constant, the movement of the rollers is smooth. Therefore, it is not necessary to increase the rigidity by increasing the thickness of the clutch outer itself as in the past, and the overrunning clutch can be made smaller and lighter.
又クラッチカバーも冷鍛成形が可能となるため生産性に
富み、精度の高い製品が提供できる。Furthermore, the clutch cover can also be cold forged, which increases productivity and allows us to provide highly accurate products.
本発明によれば、クラッチアウターの外周部の肉厚を薄
くし、開口端の拡がり防止できるので小形軽量で、粘度
の高いオーバーランニングクラッチが提供できる。According to the present invention, the wall thickness of the outer circumferential portion of the clutch outer can be made thin and the opening end can be prevented from expanding, so that it is possible to provide an overrunning clutch that is small, lightweight, and has high viscosity.
