TORQUE DETECTING MECHANISM FOR FLEXIBLE MESHING GEAR

摘要

PROBLEM TO BE SOLVED: To obtain a torque detecting mechanism for flexible meshing gear having a torque detecting section comprising a bridge circuit of a plurality of strain gauges pasted to a flexible external gear in which wiring work and connecting work of respective strain gauges can be carried out efficiently. SOLUTION: Four pairs of strain gauges A1-D2 are bonded to the annular diaphragm 33 of a flexible external gear 3 in a flexible meshing gear and an annular flexible printed wiring board 7 provided with openings 81-84 at the bonding position of respective strain gauges is arranged on the diaphragm 33. Wiring patterns 71-78 for connecting respective strain gauges into a bridge are formed previously on the wiring board 7. Wiring and connecting work is ended by simply soldering the lead terminals of each strain gauge to the terminal parts of the wiring patterns 71-78. Consequently, wiring and connecting work can be carried out efficiently in a short time.
