オイルレシーバー3Aは、飛散、飛翔あるいは滴下する潤滑油を受け部32の開口321から受け、底面322に沿って排出部323に流し、排出部323から潤滑油路235へと導出する。潤滑油路235へと流れた潤滑油は、流れ込んだオイルレシーバー3Aとは逆側から潤滑油路235を流出していき、潤滑油を供給したい箇所やケース1の底部(図示略)へと導かれる。例えば、入力軸21又は出力軸22の転動部材(ギヤなど)の外周側、入力軸21や出力軸21の内部に区画された流路から転動部材の内周側、あるいは下に溜まっている潤滑油に戻す、などが考えられる。 (Flow of lubricating oil received by the

次に、本実施形態1のオイルレシーバー3Aを変速機に組み付ける方法を説明する。まず、アイドラ軸23にアイドラギヤ231とオイルレシーバー3Aとを組み付ける。どちらを先に組み付けても良い。アイドラギヤ231はベアリング236とともに、図3に示すようにアイドラ軸23の一端232側から挿入され、アイドラ軸23の段差237に当接する。アイドラギヤ231及びベアリング236は、段差237によって、軸線方向で他端233側への移動が規制される。オイルレシーバー3Aは、アイドラ軸23の潤滑油路235に受け部32の排出部323を係合し、アイドラ軸23の被係合部238に保持部33の係合部332を係合し、アイドラ軸23に組み付けられる。アイドラ軸23にアイドラギヤ23及びオイルレシーバー3Aが組み付けられた状態をアイドラ軸サブアッシーと称する。 (Assembly method of
Next, a method for assembling the
本実施形態1のオイルレシーバー3Aは、アイドラ軸23とリアケース11との間に位置し、軸支持部31のあるアイドラ軸23側がアイドラ軸23と当接し、受け部32のケース当接部324及び保持部33の設置部333がリアケース11に当接する。受け部32と保持部33とは軸支持部31で一体的に連結している。変速機が組み立てられた状態あるいはフロントケース13を下側にしてアイドラ軸23が組み付けられる場合は、アイドラ軸23はフロントケース13に軸支される。そして、フロントケース13を下側にしてアイドラ軸23が組み付けられる場合はアイドラギヤ231がフロントケース13に保持される形状、構成である(図3参照)。リアケース11を下側にして組み付ける際は、アイドラ軸23及びアイドラギヤ231は直接リアケース11に当接しないため、オイルレシーバー3Aによってリアケース11に対して保持される。オイルレシーバー3Aは単にアイドラ軸23とリアケース11との間に位置して当接しているだけではない。受け部32はアイドラ軸23側からリアケース11に向かって広がる形状である。保持部33は受け部32の広がる方向の逆側に位置する。つまり、オイルレシーバー3A全体として二股に分かれてアイドラ軸23を保持している。オイルレシーバー3Aは、ケース1からはみ出したりする形状ではないため、組み付け作業で邪魔にならない。更に、保持部33は、オイルレシーバーとしての機能に直接関係ないが、オイルレシーバー3Aが位置を保持するのに貢献している。オイルレシーバー3Aの排出部323とアイドラ軸23の潤滑油路235との係合が隙間なくしっかりと嵌合していなかったとしても、保持部33によって、当該係合が外れにくい。よって、リアケース11を下にして組み付け作業が行われる場合、オイルレシーバー3Aによってアイドラ軸23及びアイドラギヤ231は位置を保持し、組み付けが困難であったり、組み付けに支障がでたりし難い。 (effect)

本実施形態2のオイルレシーバー3Bは、図4に示すように、軸支持部31と受け部32と保持部34とを備える。軸支持部31、受け部32及びアイドラ軸23は、実施形態1のオイルレシーバーの軸支持部31及び受け部32、そしてアイドラ軸23と同様の構成であるため、詳細な説明は省略する。 (Embodiment 2)
As shown in FIG. 4, the
本実施形態3のオイルレシーバー3Cは、図5に示すように、軸支持部31と受け部32と保持部35とを備える。軸支持部31、受け部32及びアイドラ軸23は、実施形態1のオイルレシーバーの軸支持部31及び受け部32、そしてアイドラ軸23と同様の構成であるため、詳細な説明は省略する。 (Embodiment 3)
As shown in FIG. 5, the
以上、本発明の好適な実施形態について説明したが、本発明は上記実施形態に限定されるものではない。例えば、オイルレシーバー3(3A、3B、3C)の排出部323は、潤滑油路325に隙間なく係合しなくても良く、ケース当接部324及び設置部333がリアケース11に当接することで、リアケース11を下側にして組み付け作業が行われてもアイドラ軸23は保持される。アイドラ軸23は、ミドルケース12やフロントケース13が設置される際に、保持が維持されれば、ケース1に対して固定される。変速機として組み立て後、つまり、受け部32の開口321が上方に位置する状態においても、軸支持部31及びリアケース11に当接する保持部33~35の形状によりオイルレシーバー3は下方に下がりにくい。 (Other embodiments)
