Abstract
PURPOSE: To measure clamping torque continuously, by fixing the torsion bar, to which the strain gauge is stuck, onto the outside circumference of the internal gear which gears with the epicyclic gear which decelerates rotation of the driving source.
CONSTITUTION: Decelerated rotation force from the driving source is transferred to the driving shaft, which has the end part fixed to disc 34, through epicyclic gear 32, which gears with the internal teeth of internal gear 30 and is arranged in the position of the regular triangle on disc 34, by the pinion gear fixed to output shaft 40, and the clamping work of the bolt, the nut, and so on is performed through chuck 54 and the driver. since torsion bar 18 to which strain gauge 20 extending from slit 44 of cylindrical casing 16 in the radius direction is fixed to the outside circumference of internal gear 32, the counter load at the clamping work time is transferred to internal gear 32 to distort torsion bar 18 whose rotation is controlled by stopper 51, and thus, clamping torque is detected.
