The invention discloses a double-speed-ratio water-air dual-purpose power device. The double-speed-ratio water-air dual-purpose power device mainly comprises a power input device, a rotating speed switching device and paddles. The power input device always provides power in a high-rotating-speed and low-torque state under different media, and the rotating speed switching device converts power input into torque meeting the requirements of the media through a one-way bearing and a planetary speed reduction mechanism under different media. When the power unit is in the air, the planetary reducing mechanism loses action, the output of the rotating speed switching device is equal to the rotating speed and torque of the power input device, when the power unit is in the water, the planetary reducing mechanism operates, and the output rotating speed of the rotating speed switching device is smaller than the rotating speed of the power input device. The torque output by the rotating speed switching device is larger than that of the power input device. The output shaft of the rotating speed switching device drives the passive folding propeller to provide power, and the passive folding propeller can passively stretch, fold and contract according to different rotating speeds and media, so that high efficiency under different media is ensured.
本发明公开了一种双速比的水空两用动力装置,主要包括:动力输入装置、转速切换装置以及桨叶。动力输入装置在不同介质下总以高转速低扭矩的状态提供动力,转速切换装置在不同介质下,通过单向轴承和行星减速机构将动力输入转换为满足所处介质要求的扭矩。当动力单元处于空中时,行星减速机构失去作用,转速切换装置的输出等于动力输入装置的转速和扭矩,当动力单元处于水中时,行星减速机构运行,转速切换装置的输出转速小于动力输入装置的转速,转速切换装置输出的扭矩大于动力输入装置的扭矩。转速切换装置的输出轴驱动被动折叠螺旋桨提供动力,且被动折叠螺旋桨根据转速与介质的不同,会被动进行伸张和折叠收缩,保证了不同介质下的高效性。
