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の表面に図示せぬコーティング層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及び細溝3の深さの公差a2の和を引いた長さよりも短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、細溝3の深さの公差をa2としたとき、細溝3の深さdは、d<h1-(a1+a2)で表される。
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よりも小さくなるため、細溝3を形成する際に、刃具が金属層21に接触することが無くなるので、刃具の長寿命化を図ることができる。
プレス加工は、圧縮プレス機を用いて行われる。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及び細溝3の深さの公差a2の和を引いた長さよりも短くなるように形成する。
このように構成することにより、細溝3の深さdは、ライニング層22の厚さh1よりも小さくなる。細溝3の深さdが、ライニング層22の厚さh1よりも大きくなると、金属層21まで細溝3を形成する必要があり、プレス加工による細溝3の形成が困難となる。細溝3の深さdが、ライニング層22の厚さh1よりも小さくなることにより、プレス加工による細溝3の形成が可能となる。
周縁部形成工程S40においては、周縁部2aの内周面2cを、細溝3の底面3aよりも内周側に形成したため、周縁部2aの内周面2cもライニング層22内に形成される。これにより、プレス加工による周縁部2aの形成が可能となる。
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及び細溝3の深さの公差a2の和を引いた長さよりも短くなるように形成したことにより、円鋸などの刃具により細溝3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。また、プレス成型が可能な硬度であるライニング層22にのみ細溝3を設けるので、プレス成型による細溝3の形成も可能となる。
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。また、プレス成型が可能な硬度であるライニング層22にのみ周縁部2aを設けるので、プレス成型による周縁部2の形成も可能となる。
