Abstract
A rotary type component force measuring device capable of finding a highly accurate component force is provided. This measuring device has a rotary type component force detector comprising in integrated manner, a rim mounting frame, a hub mounting frame, a second sensing beam of a character I shaped sectional type which couples and the mounting frames, and a first sensing beam which couples the second sensing beam and the mounting frame, wherein each of front and back surfaces of receiving sensor portions adhere with each of orthogonal shearing type strain gauges A1 to H4, and a signal is derived from the strain gauges A1 to H4 by a bridge circuit for each receiving sensor portion, and the output signals from the bridge circuit are sampled by an electronic circuit disposed on the inside of a rotating unit according to the timing signal from an angle detection signal, and the output signals are transmitted to a signal processing unit disposed on the outside of the rotating unit by non-contact data transmission method, and the output signals are corrected by correction information for every rotation angle position of the detector storing the output signals beforehand, and are subjected to coordinate conversion so as to calculate the six component forces for every angle rotation.
