ABSTRACT:
A wave gear device torque detection method in which the gain of the output of each of a plurality of strain gauge sets affixed to the diaphragm of a flexible external gear is amplified and the outputs are then combined to form a detection signal. Adjusting the gain of each of the strain gauge outputs makes it possible to compensate for rotational ripple included in the output. Compensation of up to n order ripple components is possible by using at least (2n+1) strain gauges.
