Abstract
Description
(1)軸受が支持する回転子に設けられた冷却ファンがブラケット軸受箱に対向しており、軸受箱外縁の螺子貫通穴座との干渉を回避する為軸受サイズを縮小する必要があり、耐久性が低下する。軸受サイズを縮小できない場合、ファン面積を縮小する必要があり、冷却性が低下する為、出力性能、耐久性に影響がある。
(2)さらに、軸受箱外縁に螺子貫通穴座が設けられているため、回転子冷却ファンと軸受箱、軸受箱外縁螺子貫通穴座との間隔に差ができる為、冷却ファンによる風切り音が発生する要因となる。
(3)ブラケット軸受箱とリテイナは別に設けた螺子により締結されているが、リテイナと軸受箱端面は隙間があるため外部からの水、塵埃が軸受箱に浸入する構造である。
また、リテイナ外周の雄螺子と軸受箱内周の雌螺子の締結により外部からの水、塵埃が軸受箱内に侵入しにくくなる。
図1はこの発明の実施の形態1による車両用交流発電機の全体構成を示す断面図、図2は、図1に示す車両用交流発電機の部分断面図、図3は、図1に示すフロントブラケットの側面図である。
図1~図3において、1はフロントブラケットで、中央部に軸受箱11が形成されている。2は回転軸、3はこの回転軸2を回転可能に支承する軸受で、内輪31が回転軸2に嵌着され、外輪32が軸受箱11に嵌着されている。33は軸受3のボ-ルで円周上複数個設けられている。4は回転軸2に固着された界磁鉄心で、1対の爪状磁極から構成されている。5はこの界磁鉄心4の側部に固着された冷却ファンで、遠心ファンからなり、フロントブラケット1に形成された吸入口1aから冷却風を吸入し、フロントブラケット1の外周部に設けられた排気口1bから排出するように機能する。6は回転軸2の先端に固着されたプ-リで、図示しないベルトを介してエンジンのクランク軸により駆動される。7はプ-リ6を回転軸2に固着するためのナットである。
9は、軸受3の内輪31と界磁鉄心4との間に装着されたスペ-サである。
また、軸受サイズが同じ場合、ファン面積を拡大することができ、冷却性能が向上することで、発電機出力性能の向上、構成部品の温度低減による耐久性の向上が可能となる。
更にまた、リテイナ8外周の雄螺子81と軸受箱11内周の雌螺子111との螺着により外部からの水、塵埃が軸受箱11内に浸入しにくくなる。
しかも、軸受箱11の螺合部およびリテイナ8のナット部82が、冷却ファン5内周部において、吸入穴1aからの浸入物に対してラビリンス作用をなすので、軸受3への浸入物の影響を少なくでき、軸受3の信頼性向上に寄与する。
図4は、この発明の実施の形態2による車両用交流発電機の全体構成を示す断面図、図5はこの図4に示す車両用交流発電機の部分断面図、図6は、図4に示すフロントブラケットの側面図である。
図4~図6において、10は、軸受3を軸受箱11に固定保持するリテイナで、鋼などの金属製で、円筒形状をなし、外周部の内周側に雌螺子部101が形成されており、内周部にはリテイナ10の螺子を回すための螺合部である6角上に突出したナット部102が形成されている。このリテイナ10の雌螺子101は、軸受箱11の外周部に設けられた雄螺子112に螺着可能に構成されている。
図7は、この発明の実施の形態3に係る車両用交流発電機の要部を示す断面図である。
図7において、12は、リテイナ10の雌螺子部101の右端部とフロントブラケット1の軸受箱11の雄螺子部112基部との間に装着されたゴム等の弾性体からなるリング状のシ-ル材である。
また、この実施の形態3では、シ-ル材12としてゴム等の弾性体を例示したが、樹脂またはシ-ル性の高い塗料でも良いし、更には、錆止めを兼ねたグリ-ス等でも良い。
