面议双向推力角接触球轴承
双向推力角接触球轴承具有精度高、刚性好、润滑充分、温升低、转速高和拆卸方便等优点。因而被广泛应用于磨床、镗床、铣床、车床和钻床等主轴上。
双向推力角接触球轴承的特点是可以同时承受径向和轴向载荷的联合载荷,限制轴的两方面的轴向位移。它是由外圈、内圈、钢球、保持架组成,能在较高的速度下稳定地工作。安装时应注意,虽然轴承可承受双向轴向载荷,但若一侧有装球缺口时,则应注意不要让主要轴向载荷通过有缺口的一侧沟边。
当它与NN3000K型圆锥内孔的双列圆柱滚子轴承配用时,双向推力角接触球轴承可以放置在圆锥轴颈的任何一面。通常2344系列置于锥轴颈的小轴颈的一面,2347置于大轴颈的一面。建议优先选用2344系列轴承。
