YDPB高精度高速角接觸球軸承 H719系列;HC719系列;H70系列;HC70系列;B70系列
1、結(jié)構(gòu)特點(diǎn): 采用小球設(shè)計(jì)的高速系列;
2、套圈材料:采用國(guó)產(chǎn)高純凈軸承鋼,配合特殊的熱處理工藝,冷處理工藝以及材料改性技術(shù),使得該系列軸承疲勞壽命大幅度提高。
3、接觸角: 分15o和25o,成對(duì)使用可承受軸向負(fù)荷和徑向負(fù)荷或合成負(fù)荷。
4、保持架:外圈引導(dǎo)的酚醛樹(shù)脂夾布膠木保持架;可長(zhǎng)期在80°以下穩(wěn)定工作。
5、滾動(dòng)體材質(zhì):鋼球(H719,H70,B70) 陶瓷球(HC719,HC70) 一般中高速工況推薦選用鋼球,高速及特殊工況可選用陶瓷球。
6、速度因子: 滾動(dòng)體為鋼球時(shí)(H719,H70,B70)
油脂潤(rùn)滑 DmN≤1200000 即 極限轉(zhuǎn)速N≤1200000/Dm
Dm—軸承中徑 油(***少量)潤(rùn)滑 DmN≤1800000
滾動(dòng)體為陶瓷球時(shí)(HC719,HC70)
油脂潤(rùn)滑 DmN≤1400000 即 極限轉(zhuǎn)速N≤1400000/Dm
Dm—軸承中徑 油(***少量)潤(rùn)滑 DmN≤2200000
7、適用范圍: 此類(lèi)軸承適用范圍很廣;主要用于高轉(zhuǎn)速,高精度旋轉(zhuǎn)等工況,例如:數(shù)控加工中心主軸,磨削用高速電主軸,磨床砂輪主軸,高速精密機(jī)械等??商峁╊A(yù)裝油脂的密封式軸
