在这项研究中，我们开发了新的蜗轮机构与被动滚子作为他们的牙齿，并确认这些蜗轮与被动滚子的有用功能，以传递动力从蜗轮与更高的能量效率比普通蜗轮。所研制的蜗轮采用被动滚子作为轮齿，以滚动摩擦阻力代替滑动摩擦阻力，实现了高功率传动效率。分别制作了锥形被动滚子蜗轮和盘形被动滚子蜗轮，并进行了实验研究。实验还表明，被动滚子蜗轮具有传统蜗轮难以实现的平滑反向驱动能力。实验结果表明，所研制的被动滚子蜗轮蜗杆传动机构可以在相同齿数和模数的情况下代替普通蜗轮蜗杆传动机构中的蜗轮，实现更高的能量效率和平稳的反向驱动性能。这些特征对于在人类环境中实现自动化系统的安全和软致动器非常有用。
In this study, we developed new worm wheel mechanisms with passive rollers as their teeth and confirmed useful functions of these worm wheels with passive rollers to transmit power from worm gears with higher energy efficiency than ordinary worm wheels. By using passive rollers as their teeth, the developed worm wheels could realize high-power transmission efficiency with rolling frictional resistance instead of sliding frictional resistance. A worm wheel with conical passive rollers and one with disk-shaped passive rollers was fabricated as prototypes and examined in experiments. Smooth back-drivability of the worm wheels with passive rollers, which is difficult to realize with conventional worm wheels, was also demonstrated in the experiments. These serial experiments revealed that the developed worm wheel mechanism with passive rollers can replace conventional worm wheels with the same number of teeth and module in ordinary power transmission mechanisms with worm gearing and realize higher energy efficiency and smooth back-drivability. These features can be very useful to realize safe and soft actuators for automation systems in a human environment.
