Claims (4)

内輪と外輪との間に転動体を配置し、潤滑剤で潤滑されて使用される転がり軸受において、外輪及び転動体間の摩擦係数に対する内輪及び転動体間の摩擦係数の比が0.8より大きく且つ1.0未満であり、且つ転動体との摩擦係数が小さくなると共に圧縮残留応力が発生する表面処理を内輪に施したことを特徴とする転がり軸受。 In a rolling bearing used with a rolling element disposed between the inner ring and the outer ring and lubricated with a lubricant, the ratio of the friction coefficient between the inner ring and the rolling element to the friction coefficient between the outer ring and the rolling element is more than 0.8. A rolling bearing characterized in that the inner ring is subjected to a surface treatment that is large and less than 1.0 and that has a small coefficient of friction with a rolling element and generates compressive residual stress. 内輪の残留オーステナイト量が外輪の残留オーステナイトより少ないことを特徴とする請求項1に記載の転がり軸受。The rolling bearing according to claim 1, wherein the amount of retained austenite of the inner ring is smaller than the amount of retained austenite of the outer ring. 下記で表す内輪及び転動体間の油膜パラメータが0.8より大きく、外輪及び転動体間の油膜パラメータが4.0未満であることを特徴とする請求項1又は2に記載の転がり軸受。The rolling bearing according to claim 1 or 2, wherein an oil film parameter between the inner ring and the rolling element expressed below is greater than 0.8, and an oil film parameter between the outer ring and the rolling element is less than 4.0.
油膜パラメータ:Λ=hOil film parameter: Λ = h min min /(R/ (R 1rms1rms 2 2 +R+ R 2rms2rms 2 2 ) 1/2 1/2
