1P1-C07 Prototype Design of a Small and Quiet Cyclo Reducer with Eccentric Input by Planetary Gear Mechanism Using Rubber Roller
Daiki Sato, Shoichi Hasegawa · The Proceedings of JSME annual Conference on Robotics and Mechatronics (Robomec) · 2015
In this paper, we propose a novel cycloidal speed reduction system. The system is consist of internal gear, cycloidal disk and rubber roller planetary gear inside the cycloidal disk. A motor shaft drives rubber roller directly by friction, and the roller turns around inside the cycloidal disk, pressing the disk to the internal gear. This roller turning is the eccentric input of cycloidal speed reducer. The feature of this reducer is quiet, high reduction ratio, small-size and low-cost. These features will help decreasing actuators' noise of entertainment robots and toy robots, which will improve pleasure of experience and qualities of speech recognition of the robots. The prototype of this speed reducer worked successfully, and noise was less than ordinal hobby servo motor.
