Abstract
ボール傷の発生を防止し、音響特性と寿命の向上を図った車輪用軸受装置を提供する。
【解決手段】
複列アンギュラ玉軸受で構成された車輪用軸受装置において、内側転走面13aの溝底部近傍に溝底径d1よりも所定のカチコミ代δだけ大径に形成されたカウンター部18が形成され、このカウンター部18が、内側転走面13aから軸方向に延びる円筒部18aと、この円筒部18aから内輪13の小端面13bに向って縮径するテーパ面18bとで構成されると共に、カウンター部18と内側転走面13aとの繋ぎ部Aおよび円筒部18aとテーパ部18bの角部が円弧状に丸められ、滑らかに連続して形成されている。これにより、内輪13の組立時におけるボール14のカチコミ傷の発生を防止することができる。
