double tapered roller

基本解释

Double row tapered roller bearings can accommodate simultaneously radial load and also axial load in double directions.
双列圆锥滚子轴承在承受径向负荷的同时也可承受双向轴向负荷。
Tapered roller bearings for machine tools can be both radial and axial loads, double row tapered roller bearings can withstand two-way axial load.
机床用圆锥滚子轴承可同时承受径向和轴向载荷，双列圆锥滚子轴承可承受双向轴向载荷。
Particulary, the double-row parallel roller bearing is superior to the tapered roller bearing in the first mode of vibration, but inferior to the latter in the second and third modes.
尤其在一阶振型时双列圆柱滚子轴承的结构型式优于圆锥滚子轴承，但是在二、三阶振型时则劣于后者。
