Abstract
PURPOSE:To perform accurate torque detection by mounting potentiometers on the transmission shafts of an input and an output shafts and sending and receiving a detection current through only a lead-out wire. CONSTITUTION:The potentiometers 9a and 9b are fitted on the supporting shafts 8a and 8b coupled with the input shaft 1 and output shaft 2 at the same speed reduction rate, and torque applied to the input shaft 1 is detected from the difference in detected value between meters 9a and 9b. Therefore, the detection current need not by sent and received through a slip ring and a brush unlike a potentiometer consisting of a low resistor and a slider fitted on the input shaft and output shaft, so the detection current can accurately be detected without being affected by sliding and wear.
