详细说明

  转盘轴承是一种能够同时承受较大的轴向负荷、径向负荷和倾覆力矩等综合载荷的特殊结构的大型轴承。一般情况下,转盘轴承自身均带有安装孔、润滑油孔和密封装置,可以满足各种不同工况条件工作的各类主机的不同需求;另一方面.转盘轴承本身具有结构紧凑、引导旋转方便、安装简便和维护容易等特点,被广泛用于起重运输机械、采掘机械、建筑工程机械、港口机械和导弹发射架等大型回转装置上。

  转盘轴承根据不同的结构型式可以分为四点接触球转盘轴承、双排角接触推力球转盘轴承、交叉圆柱滚子转盘轴承、交叉圆锥滚子转盘轴承和三排圆柱滚子组合转盘轴承等不同的结构型式;上述各类轴承按其是否带齿及轮齿的分布部位又分为无齿式、外齿式或内齿式等不同结构。

  1.四点接触球转盘轴承四点接触球轴承是一种分离型轴承,也可以说是一套轴承可承受双向轴向载荷的角接触球轴承,其内外圈滚道是桃型的截面,当无载荷或是纯径向载荷作用时,钢球和套圈呈现为四点接触,这也是这个名称的由来;当只有纯轴向载荷作用时,钢球和套圈就成了两点接触,可承受双向的轴向载荷。四点接触球轴承还可以承受力矩载荷,兼有了单列角接触球轴承和双列角接触球轴承的功能。四点接触球轴承只有形成两点接触时才能保证正常的工作。所以一般适用于那些纯轴向载荷或轴向载荷大的合成载荷下呈两点接触的场合,四点接触球轴承极限转速高,也适合于那些高速运转的场合.
