    • PROBLEM TO BE SOLVED: To suppress variations in the cooling state when a generator motor is cooled by a cooling medium.SOLUTION: A cooling structure 100 of a generator motor includes: a first passage 32 which is provided at a flange 12 of the generator motor, extends toward a rotation center axis Zr of an input/output shaft 16 stored in a first housing 11 to open at the input/output shaft 16 side, and has a draw part 35 in a middle part thereof; and a second passage 33 which is provided at the flange 12, is divided from the first passage 32 at a position close to the radially outer side of the input/output shaft 16 relative to the draw part 35, and extends toward a rotor 20 attached to the outer side of the input/output shaft 16 to open at the rotor 20 side.
    • 要解决的问题:为了抑制发电机用冷却介质冷却时的冷却状态的变化。 解决方案:发电机电动机的冷却结构100包括:设置在发电电动机的凸缘12处的第一通道32朝向存储在第一壳体中的输入/输出轴16的旋转中心轴线Zr延伸 11在输入/输出轴16侧打开,并且在其中间部分具有拉伸部分35; 并且设置在凸缘12处的第二通道33相对于牵引部35在靠近输入/输出轴16的径向外侧的位置处与第一通道32分开,并且朝向附接的转子20延伸 到输入/输出轴16的外侧,以在转子20侧打开。 版权所有(C)2013,JPO&INPIT
