Abstract
【解決手段】 鉄道用車両の主軸を支持する転がり軸受は、内輪と、外輪と、複列に配置された円錐ころと、保持器と、密封部材とを備える複列円錐ころ軸受である。軸受内部には封入されるグリース量の軸受内部全空間体積に対する体積割合は25〜35%である。
【選択図】 図2
Description
グリース封入割合[%]:15,20,25,30,35,40
軸受許容温度[℃] :120
軸受体積 :1063.3cm3(全空間),698.2cm3(静止空間),1585.2cm3(動空間)
これによると、全空間体積に対するグリース封入量の体積割合は、28.1%〜31.3%であるのに対し、静止空間では、43.0%〜47.7%,動空間では、18.9%〜21.0%との結果を得た。
