METHOD FOR DETECTING TORQUE OF WAVE MOTION GEAR DEVICE

摘要

PROBLEM TO BE SOLVED: To propose a method for detecting a torque of a wave motion gear device which can precisely detect a transmission torque based on an output of a strain gage laminated on a flexible external tooth gear. SOLUTION: The method for detecting the torque of the wave motion gear device includes the steps of gain regulating and then compositing outputs from a plurality of sets of strain gages laminated on a diaphragm of the flexible external tooth gear by an amplifier, and generating a detection signal. A rotating ripple including in the output can be compensated by gain regulating each strain gage output. When components up to an n-th order included in the rotating ripple are compensated for, the rotary ripple can be surely compensated by laminating (2n+1) or more strain gages. COPYRIGHT: (C)2004,JPO
