Abstract

PURPOSE:To achieve wide-range torque detection by arranging torsion bars, differing in the extent of torsion to load torque, between a driving shaft and a driven shaft through electromagnetic clutches, and providing a torque detection plate to each shaft. CONSTITUTION:Between a driving shaft 1 and a driven shaft 7, torsion bars 4, 5 and 8 are arranged through electromagnetic clutches 23, 24 and 51, and the driving shaft 1, intermediate shafts 3 and 6, and the drive shaft 7 are provided with torque detection plates 9-12, respectively. The torsion bars 4, 5 and 8 increase in the extent of torsion in this order. The torque detection plates 9-12 have 360 slits at equal intervals, and the passing of the slits accompanying the rotation of the driving shaft 1 is detected by photocouplers 15-18, whose output pulses are stored in a storage device through a counter and then processed to detect load torque. When the angles of torsion of the torsion bars 4, 5 and 8 exceed a prescribed value, the electromagnetic clutches 51, 23 and 24 operate successively to achieve wide-range torque detection.
