摘要： PURPOSE:To make it possible to control steady-state rotation and dynamic torque independently by loading repeating torque on a pair of members under test with a differential gears, and loading reverse torques to each other on a motor through a pair of the members under test. CONSTITUTION:When a motor 7 is rotated in the direction of an arrow R, relay shafts 6a and 6b are rotated in the directions of arrows S and S' through bevel gears 10, members under test 4a and 4b are rotated in the same direction T and torque transmitting shafts 3a and 3b are rotated in the directions of arrows S and S'. The output shaft of a torsion actuator 1 is not rotated at all in this state. When torque is generated in the direction of an arrow (r) with an actuator 1, rotations S and S' in the same direction are generated in shafts 3a and 3b, the rotations in the directions (t) and (t') are generated in shafts 5a and 5b and rotations (u) are generated in the same direction in the shafts 6a and 6b. The rotations are transmitted to a bevel gear 10c of the motor 7 through gears 10a and 10b. Since the gears 10a and 10b are intermeshed with the gear 10c, force for displacing the gear 10c in the orthogonal direction with respect to paper surface is applied, but the rotation of the motor 7 is not affected. The torque is measured with a torsion sensor 11.

摘要： PURPOSE:To obtain such characteristics that an output voltage is never refracted nearby zero to load pressure by adding a displacement detector regarding an actuator to an input signal line from a displacement gage through a displacement amplifier and a correcting circuit. CONSTITUTION:The signal of a pressure signal line psl which connects a pressure amplifier 14 is applied to a 1st addition point 19 from a pressure sensor 3 with a signal applied to an actuator 1. At the same time, the signal from the actuator 1 is connected as a correction signal line csl to a 2nd addition point 20 from the displacement detector 9 through the displacement amplifier 16 and correcting circuit 17. Consequently, the output voltage is never refracted nearby zero to the load pressure and, therefore, not nonlinear, so excellent characteristics are obtained.
