The d9b can be equipped with a power take - off designed for propeller shaft operation or direct - mounted hydraulic pumps D9b可提供适用于驱动轴运转或直接安装式液压泵的动力输出。
Small craft with inboard engine - propeller shaft ends and bosses with 1 : 10 taper iso 4566 : 1992 ; german version en iso 4566 : 1995 舱内安装发动机的小型船舶.锥度为1 : 10螺旋浆轴端和
Tapers and other outboard details of propeller shafts - specification for shafts of diameter greater than 160 mm up to 1000 mm 螺旋浆轴的锥体及其它外舷零件.第2部分:直径大于160mm并达到1000mm的轴规范
This accommodates any effective change of length of the propeller shaft as the rear axles move toward or away from the car frame 当后桥在车架上向前或向上运动时,这种结构足以调整传动轴长度的任何变化。
The ship radiated noise is analyzed and its 4 features are extracted from the envelop spectrum . the envelope of ship noise waveform can be demodulated utilizing hilbert transform , and the spectrum components with line rotation frequency of propeller shaft are extracted effectively by bispectrum , 1 ( 1 / 2 ) spectrum and 2 ( 1 / 2 ) spectrum analysis 对于通过希尔伯特变换解出的舰船辐射噪声包络信号进行高阶统计量分析,有效地提取出了舰船噪声的双谱、 11 / 2维谱、 21 / 2维谱等方面的特征。
