轴套筒 meaning in English

shaft sleeve

Under the assumption that the inner surface of stator sleeve and outer surface of rotor are smooth , taking the fact into account that the temperature of stator sleeve of evaporation cooling motor keeps almost the same , horizontal evaporation cooling motor is simplified as a physical model of two coaxial sleeves , with outer sleeve ( the stator ) holds still and keep at constant temperature and inner sleeve ( the rotor ) is rotating and heated
本文通过数值和实验手段研究了卧式蒸发冷却电机楔形气隙中的流体流动、传热现象。本文在定子套筒和转子表面光滑的假设下，针对蒸发冷却电机定子套筒壁面基本恒温的特点，将实际蒸发冷却电机简化为同轴套筒内筒加热旋转、外简静止定温的物理模型。
