About

Kenji Imase is a mechanical engineer whose research has made significant contributions to the design and analysis of advanced gear reduction systems, with a particular focus on cycloid and trochoidal mechanisms for precision motion control applications. His most influential work centers on the Cycloid Ball Reducer, a novel speed reduction device comprising two surface-grooved discs and a train of balls featuring epicycloidal and hypocycloidal wave grooves. Beginning with his foundational 1988 analysis — which has accumulated 19 citations — Imase systematically advanced understanding of this technology through multiple research reports, culminating in a 1997 study presenting rigorous theoretical efficiency calculations and optimal design methodologies, garnering an additional 10 citations. This body of work established a comprehensive analytical framework that has informed the development of compact, high-precision actuators suitable for robotic applications. More recently, Imase extended his expertise to trochoidal gear systems, developing a reducer integrated with a slipping roller-type torque limiter in 2013, demonstrating his continued engagement with practical engineering solutions. His career reflects a sustained commitment to advancing the theoretical foundations and real-world applicability of specialized gear transmission technologies in robotics and automation.
