Abstract
Description
すべり軸受1は円筒状の部材であり、図1に示すように、エンジンのクランクシャフト11のすべり軸受構造に適用される。すべり軸受1は、二つの半割部材2・2で構成されている。二つの半割部材2・2は、円筒を軸方向と平行に二分割した形状であり、断面が半円状となるように形成されている。本実施形態においては、半割部材2・2は上下に配置されており、左右に合わせ面が配置されている。クランクシャフト11をすべり軸受1で軸支する場合、所定の隙間が形成され、この隙間に対し図示せぬ油路から潤滑油が供給される。
下側の半割部材2の内周において、その軸方向の端部に細溝3が形成されている。
また、細溝3の軸方向外側面を形成する周縁部2aは、半割部材2の外周面からの高さhが、半割部材2の外周面から当接面までの高さDよりも低くなるように形成されている。すなわち、軸方向外側の周縁部2aが周囲のクランクシャフト11との当接面よりも一段低くなるように形成されている。
細溝3は下側の半割部材2に設けられる。本実施形態においては、細溝3は軸方向に並列して二本設けられている。詳細には、細溝3は、クランクシャフト11の回転方向下流側合わせ面(軸受角度ωが180度)と離間した位置(軸受角度ωがω1)から軸受角度ωが正となる方向(反時計回り方向)に向けて、軸受角度ω2まで円周方向に設けられる。下側の半割部材2においては、図2(B)の右側の合わせ面が回転方向上流側合わせ面、図2(B)の左側の合わせ面が回転方向下流側合わせ面となる。
細溝3の幅は、図2(C)に示すように、wとなるように形成されている。
また、細溝3の深さdは、半割部材2の外周面から当接面までの高さDよりも短くなるように形成されている。
下側の半割部材2の製造方法は、金属層21にライニング層22を貼設するライニング層形成工程S10と、ライニング層22及び金属層21を半円形状に成形する成形工程S20と、細溝3を形成する第一の工程である細溝形成工程S30と、周縁部2aを形成する第二の工程である周縁部形成工程S40と、ライニング層22の表面に図4に示すコーティング層23を形成するコーティング層形成工程S50と、を備える。以下に、各工程について具体的に説明する。
切削加工は、円鋸のような刃具によって行われる。細溝形成工程S30においては、細溝3の深さdを、ライニング層22の厚さh1から、ライニング層22の厚さの公差a1を引いた長さよりも長くなるように形成する。例えば、ライニング層22の厚さをh1、ライニング層22の厚さの公差をa1、細溝の深さをd、としたとき、細溝3の深さdは、d>h1-a1となるように構成される。
このように構成することにより、細溝3の深さdが、ライニング層22の厚さh1よりも長くなるため、細溝3は、ライニング層22から金属層21にわたって形成される。このため、細溝3の深さdの長さを十分に大きくとることができるため、吸い戻し油量が増加し、総和の流出油量を抑えることができる。
このように構成することにより、油膜圧力の発生を妨げない程度の細溝3を設けることで、摺動面積を減らしつつ、フリクション低減効果を得ることができ、かつ、総和の流出油量を抑えることができる。また、細溝3の深さdを、ライニング層22の厚さh1から、ライニング層22の厚さの公差a1を引いた長さよりも長くなるように形成したことにより、ライニング層22及び金属層21に細溝3を設けることができるので、細溝3の吸い戻し油量が増加し、総和の流出油量を抑えることができる。
このように構成することにより、円鋸などの刃具により周縁部2を形成する際には、ライニング層22よりも硬度の高い金属層21に刃具が当るのを防ぐことができるので、刃具の寿命が長くなる。
