642. 流体齿轮：无齿驱动的机械革新
from 知为谁 · host 知为谁
纽约大学的研究人员近期开发出一种无需齿轮齿的新型机械传动系统，通过操控流体动力来实现旋转。这项技术利用浸泡在液体中的圆柱体，依靠流体产生的涡流来驱动被动轮，从而避免了传统齿轮因接触磨损或制造缺陷而导致的故障。实验证明，通过调整旋转速度和部件间距，该系统能像齿轮或皮带轮一样工作，甚至可以改变旋转方向。这种流体齿轮相较于延续数千年的传统机械结构，具有更高的柔韧性和耐用性，有望为机器人等精密领域带来革命性突破。该研究成果已发表在《物理评论快报》上，标志着机械工程领域的一项重大创新。内容来源：https://phys.org/news/2026-01-fluid-gears-rotate-teeth-mechanical.html
