單列角接觸球軸承性能特點、分類、型號對照、負荷、尺寸參數表
角接觸球軸承可同時承受徑向負荷和軸向負荷。能在較高的轉速下工作。接觸角越大,軸向承載能力越高。因其內外圈的滾道可在水平軸線上有相對位移,所以可以同時承受徑向負荷和軸向負荷——聯合負荷(單列角接觸球軸承只能承受單方向軸向負荷,因此一般都常采用成對安裝)。高精度和高速軸承通常取15 度接觸角。在軸向力作用下,接觸角會增大。單列角接觸球軸承只能承受一個方向的軸向負荷,在承受徑向負荷時,將引起附加軸向力。并且只能限制軸或外殼在一個方向的軸向位移。若是成對雙聯安裝,使一對軸承的外圈相對,即寬端面對寬端面,窄端面對窄端面。這樣即可避免引起 附加軸向力,而且可在兩個方向使軸或外殼限制在軸向游隙范圍內?! ?
角接觸球軸承有:7000C型(∝=15°)、 7000AC型(∝=25°) 和7000B(∝=40°)幾種類型。該種軸承的鎖口在的外圈上,一般內外圈不能分離,可承受徑向和軸向的聯合載荷以及一個方向的軸向載荷。承受軸向載荷的能力由接觸角決定,接觸角大,則承受軸向載荷的能力高。該種軸承能限制軸或外殼在一個方向的軸向位移
角接觸球軸承因其內外圈的滾道可在水平軸線上有相對位移,所以可以同時承受徑向負荷和軸向負荷——聯合負荷(單列角接觸球軸承只能承受單方向軸向負荷,因此一般都常采用成對安裝)。 保持架的材質有黃銅、合成樹脂等。
