ALEXANDRIA, Va., June 18 -- United States Patent no. 12,326,186, issued on June 10, was assigned to HARMONIC DRIVE SYSTEMS INC. (Tokyo).
"Strain wave gearing and actuator" was invented by Masaru Kobayashi (Azumino, Japan).
According to the abstract* released by the U.S. Patent & Trademark Office: "A strain wave gearing has a detection mechanism that detects thrust force generated between a wave generator and an externally toothed gear. The detection mechanism is provided with a strain gauge or piezoelectric load meter, and a transmission mechanism that transmits thrust force from the wave generator to the load meter. Only rotational force is transmitted to the wave generator from a from a motor shaft side, and axial force is not transmitt...
