在相同轴负荷情况下,与普通客车相比,摆式客车车轴轴承要承受更大的横向力。为适应这种情况,西班牙国营铁路的Talgo号摆式列车采用了带有轴箱弹性元件的圆锥滚子密封轴承。Talgo列车最高试验速度曾达到230公里/时,而运行速度则限定在180公里/时以下。这种轴承是由双层的外圈、两个内圈和一个可预先调整轴向和径向间隙的保持架组成的独立装置(见图)。该轴承可预先装配、调整和填装润滑脂,并用迷宫式密封装置进行封闭。由于使用了相应的工具,密封滚动轴承安装和拆卸都很方便。这种密封滚动轴承的使用寿命为300万公里。每走行60～100万公里要进行定期检
In the case of the same axle load, compared with ordinary passenger cars, tilting axle bearings to bear greater lateral force. To cope with this situation, the Talgo trochlear for the Spanish state-run railway uses tapered roller bearings with shaft-mounted spring elements. Talgo train maximum test speed has reached 230 km / h, while the operating speed is limited to 180 km / h below. This type of bearing is a stand-alone unit consisting of a double outer ring, two inner rings and a cage that pre-adjusts the axial and radial clearances (see picture). The bearings can be preassembled, adjusted and filled with grease and sealed with a labyrinth seal. Thanks to the use of appropriate tools, sealed roller bearings are easy to install and remove. The service life of this sealed roller bearing is 3 million kilometers. Every walk 60 to 1 million km to be checked regularly
