There is disclosed a configuration in which an internal gear is housed and held by a center bracket, the center bracket is provided with a bearing at the center, rotatably supports a pinion shaft, and housed in a gear case (see Patent Document 1).

近年、自動車の燃料消費低減として信号待ち等にエンジンを停止するアイドルストップシステムが注目されているが、エンジン始動頻度増加に対応した動力伝達機構の信頼性向上とエンジン始動時の騒音抑制を目的に、減速機構の内歯車の外周にゴムダンパーを装着し内歯車への衝撃荷重を吸収しギアケースへの荷重伝播を抑制し騒音低減する技術が開示されている。（特許文献２参照）   In recent years, an idle stop system that stops the engine at a signal or the like has attracted attention as a way to reduce fuel consumption of automobiles. There is disclosed a technology in which a rubber damper is mounted on the outer periphery of an internal gear of a speed reduction mechanism to absorb an impact load on the internal gear, thereby suppressing load propagation to a gear case and reducing noise.

上記従来技術においては、ギアケースへの荷重伝播としてピニオンシャフトの回転支持部からの荷重伝播が配慮されず、更なる騒音抑制に向けた課題であった。   In the above-mentioned prior art, the load propagation from the rotation support portion of the pinion shaft is not considered as the load propagation to the gear case, and there is a problem for further noise suppression.

上記課題を解決するため、本発明に係る内燃機関始動用スタータは、ピニオンシャフトを回転可能に支持する軸受部材と、前記軸受部材を支持するとともに内歯車が形成され、前記内歯車の外周面および前記外周面に垂直な面に沿って段差が形成されたセンタブラケットと、前記センタブラケットを収納するギアケースと、前記センタブラケットの外周に、前記ピニオンシャフトの全周を囲うように配置されたダンパーと、を備え、前記ダンパーは、前記センタブラケットの外周において、前記内歯車の外周面に対向する位置には配置されず、かつ、前記段差に沿って前記センタブラケットに嵌合することで、前記ギアケースと前記センタブラケットに接触し、前記ギアケースへの衝撃荷重伝播を抑制する。 To solve the above problems, an internal combustion engine starting starter according to the present invention, a bearing member for rotatably supporting the pinion shaft, the internal gear while supporting the bearing member is formed, the outer peripheral surface of the internal gear and A center bracket having a step formed along a plane perpendicular to the outer peripheral surface, a gear case accommodating the center bracket , and a damper arranged on the outer periphery of the center bracket so as to surround the entire periphery of the pinion shaft. When, wherein the damper is in the outer periphery of said center bracket, not placed in a position facing the outer circumferential surface of the internal gear, and that fits into the center bracket along the step, the It contacts the gear case and the center bracket and suppresses the propagation of an impact load to the gear case.

本発明に係る内燃機関始動用スタータにおいて、前記ダンパーは、前記センタブラケットの外周でかつ前記内歯車より前記軸受部材に近い側に配置されることが好ましい。 In the starter for starting an internal combustion engine according to the present invention, it is preferable that the damper is disposed on the outer periphery of the center bracket and closer to the bearing member than the internal gear.

本発明によれば、内歯車への衝撃荷重とピニオンシャフトの回転支持部への衝撃荷重のギアケースへの伝播を同時に抑制し、ギアケースからの騒音拡散を抑制することが可能となり、動力伝達機構全体の信頼性向上が図ることができる。   ADVANTAGE OF THE INVENTION According to this invention, the propagation of the impact load to an internal gear and the impact load to the rotation support part of a pinion shaft to a gear case can be suppressed simultaneously, and it becomes possible to suppress the noise diffusion from a gear case, and power transmission The reliability of the entire mechanism can be improved.

以下、図面を用いて本発明の実施例を説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本実施形態に係るスタータ１の断面図である。図２は、本実施形態に係る動力伝達部３及びギアケース１９周辺の展開斜視図である。   FIG. 1 is a sectional view of a starter 1 according to the present embodiment. FIG. 2 is an exploded perspective view around the power transmission unit 3 and the gear case 19 according to the present embodiment.

スタータ１は、マグスイッチ2、動力伝達部3、モータ4から構成される。バッテリーからマグスイッチ2の内部に収納された励磁コイルに電流が流れると、プランジャ5が吸引され、動力伝達部3に収納されたピニオン6がシフトレバー7を介してエンジンに装着されたリングギヤ15に向かって軸方向に移動しピニオン6がリングギヤ15に噛み合わされる。   The starter 1 includes a mag switch 2, a power transmission unit 3, and a motor 4. When current flows from the battery to the exciting coil housed inside the mag switch 2, the plunger 5 is attracted, and the pinion 6 housed in the power transmission unit 3 is moved to the ring gear 15 mounted on the engine via the shift lever 7. Then, the pinion 6 moves in the axial direction, and the pinion 6 meshes with the ring gear 15.

モータ4は、積層されたコア8と、コイル9と、コンミテータ10と、シャフト11と、アーマチャー12とから構成される。アーマチャー12は、すべり軸受12a、12bに回転可能に支承される。シャフト11の先端には外歯11aが形成され動力伝達部3内の遊星歯車減速機構13の遊星歯車13aと噛合い、所定の減速比を以ってピニオンシャフト14にモータ4の回転力が伝達され、ピニオンシャフト14上のヘリカルスプラインを経てピニオン6に回転が伝達される。   The motor 4 includes a laminated core 8, a coil 9, a commutator 10, a shaft 11, and an armature 12. The armature 12 is rotatably supported by the slide bearings 12a and 12b. External teeth 11a are formed at the tip of the shaft 11, mesh with the planetary gears 13a of the planetary gear reduction mechanism 13 in the power transmission unit 3, and transmit the torque of the motor 4 to the pinion shaft 14 with a predetermined reduction ratio. The rotation is transmitted to the pinion 6 via a helical spline on the pinion shaft 14.

遊星歯車減速機構13の内歯13bは、ピニオンシャフト14を回転可能に支承するすべり軸受16を組み込んだセンタブラケット17と一体に形成される。センタブラケット17の外周にはゴム部材18を装着し動力伝達部3の外郭を成すギアケース19に収納され、ゴム部材18は、ギアケース19内周に接触可能でかつ回転方向に弾性変形可能に嵌合する。ゴム部材18はダンパーとして機能するが、本実施形態のゴム部材18に限られず、ギアケース19への衝撃荷重伝播を抑制する部材であればよい。特に本実施形態のようにゴム部材18を用いることにより、ゴム部材18が変形容易であり、ゴム部材18をセンタブラケット17への装着が容易となり、組み立て性が向上する。   The internal teeth 13b of the planetary gear reduction mechanism 13 are formed integrally with a center bracket 17 incorporating a slide bearing 16 that rotatably supports the pinion shaft 14. A rubber member 18 is mounted on the outer periphery of the center bracket 17 and is housed in a gear case 19 forming an outer shell of the power transmission unit 3, and the rubber member 18 can contact the inner periphery of the gear case 19 and be elastically deformable in the rotation direction. Fit. The rubber member 18 functions as a damper, but is not limited to the rubber member 18 of the present embodiment, and may be any member that suppresses the propagation of an impact load to the gear case 19. In particular, by using the rubber member 18 as in the present embodiment, the rubber member 18 can be easily deformed, the rubber member 18 can be easily mounted on the center bracket 17, and the assemblability is improved.

これらの構成により、エンジン始動要求によりスタータ1に通電が開始しピニオン6がリングギヤ15に噛合う際に発生する衝撃荷重は、遊星歯車機構13の内歯13bに伝達するとともにピニオンシャフト14を回転可能に支承するすべり軸受16にも印加される。しかし、内歯13ｂを一体に形成しすべり軸受16を装着するセンタブラケット17の外周にゴム部材18を装着するとことで、上記双方の衝撃荷重のギアケース19への伝播を遮断することが可能となり、スタータ1動作時の騒音抑制に高い効果が得られる。   With these configurations, the impact load generated when the starter 1 is energized by the engine start request and the pinion 6 meshes with the ring gear 15 is transmitted to the internal teeth 13b of the planetary gear mechanism 13 and the pinion shaft 14 can rotate. This is also applied to the sliding bearing 16 that supports the bearing. However, since the inner teeth 13b are formed integrally and the rubber member 18 is mounted on the outer periphery of the center bracket 17 on which the slide bearing 16 is mounted, it is possible to block the transmission of the above two impact loads to the gear case 19. Thus, a high effect can be obtained in suppressing noise during operation of the starter 1.

さらに、ゴム部材18の装着場所は、センタブラケット17の軸方向において内歯13bとすべり軸受16との間に装着することで、双方の衝撃荷重を均一に吸収することができ、騒音抑制により高い効果が得られる。   Furthermore, the mounting location of the rubber member 18 can be uniformly absorbed by both of the impact loads by mounting between the internal teeth 13b and the slide bearing 16 in the axial direction of the center bracket 17, and the noise suppression is higher. The effect is obtained.

また、ゴム部材18は、センタブラケット17の外周でかつ内歯13bよりすべり軸受16に近い側に配置されることにより、騒音がスタータ１の外部に出ることを更に抑制することができる。   Further, since the rubber member 18 is arranged on the outer periphery of the center bracket 17 and on the side closer to the slide bearing 16 than the internal teeth 13b, it is possible to further suppress the noise from coming out of the starter 1.
