[0036] exist figure 1 Contains the harmonic reducer flexible spline 1 and the strain gauge; in figure 2 Contains power input terminal 4 and voltage output terminal 5; in image 3 Contains the rubber-based solder joints 6 of the strain gauges and the placement area 7 of the strain gauges. figure 2 The middle power supply input terminal 4 and the voltage output terminal 5 are in image 3 be reflected in.
[0037] Principle: By pasting eight strain gauges on the outer wall 1 of the harmonic reducer flexspline, the torque on the flexspline is directly sensed and measured with the strain gauges. Eight strain gauges with figure 1 The arrangement is pasted on the outer wall of the flexspline 1, and the acute angle between the length direction of the strain gauge and the radial line on the flexspline passing through the center of the strain gauge is 45 degrees, and the leads of the eight strain gauges are welded on the strain gauge On the rubber-based solder joint 6 of the elec...
