Claims

[Scope of utility model registration request]

Consisting of a fixed pulley piece and a movable pulley piece, the movable pulley piece is provided on the axial extension of the fixed pulley piece so as to be movable in the axial direction and rotational direction, and the movable pulley piece is provided on one side on the axial extension of the fixed pulley piece. A resilient coil spring is interposed between the spring retainer and the movable pulley piece, and both ends of the spring are fixed to protruding pins provided on the sides of the movable pulley piece and the spring retainer, respectively. One of the pulleys is a variable speed pulley, which is configured to cause the spring to twist in the unwinding and unwinding directions according to the load due to the load generated by the belt suspended on the pulley, and the fixed V7'- is the other pulley, and a movable long tension pulley is provided between the speed change pulley and the fixed pulley, and a belt is suspended between these two pulleys and the tension pulley. A part of the shaft and integral member on one side of the fixed pulley and a part of one side of the movable pulley - 1 each
A plurality of protrusions are provided on the circumference at partial pitches, and a magnetic rotation pickup is disposed close to and facing the protrusions from outside the pulley to detect the rotation of each pulley piece during rotation. On the other hand, the relative torsion amount of one side of the movable pulley with respect to the one side of the fixed pulley is detected as a phase difference between the pulse signals emitted from one side of the fixed pulley and the one side of the movable pulley, and the signal is detected electrically. Based on this, an external actuating power is actuated via an amplifier having a control function so that the relative torsion angle of the fixed pulley piece and the movable pulley piece is maintained at a predetermined set value, and the external actuating power is used to adjust the tension. The pulley is moved, and the variable pulley piece of the one speed change pulley is moved and adjusted in the axial direction in accordance with the movement, and the winding of V<root in the speed change pulley formed by both pulley pieces has an effective diameter. A belt-type torque control device characterized by comprising an electric control means for changing the torque.
