About
Masataka Hashimoto is a mechanical engineer whose research has made significant contributions to the field of precision gear transmission systems, with a particular focus on K-H-V type planetary gears with cycloid gear configurations. His work addresses a critical challenge in robotics and precision machinery: minimizing rotational transmission error to achieve accurate positioning and smooth operation in industrial applications. Hashimoto's most influential body of work, a landmark three-part series published in 1994, systematically dissected the mechanics of rotational transmission error in cycloid planetary gear systems. The first paper, garnering 43 citations, established a rigorous analytical framework for quantifying transmission error. The second report, cited 22 times, extended this foundation by examining how manufacturing and assembly errors propagate through the system — a practically vital concern for engineers designing compact, high-reduction-ratio gearboxes. The third installment explored the mutual interactions between elemental errors, offering deeper insight into cumulative error effects. Collectively, these studies have become essential references for researchers and engineers working on precision drive systems in robotics and automated machinery, where compactness, high efficiency, and torsional stiffness are paramount. Hashimoto's work remains a foundational contribution to gear transmission analysis.
