摘要： PURPOSE:To detect the angle of torsion of a shaft to be measured with high accuracy by providing a pair of optical encoders on the same axis so as to provide a proper interval therebetween in the axial direction and inserting the shaft to be measured in the axial direction to fix the same to the rotary parts of the encoders. CONSTITUTION:Optical encoders 3, 4 are fixed to the support end plates 2 provided on both end parts of a main body case 1 on the same axis at a predetermined interval. A torsion bar 5 is inserted through the encoders 3, 4 at the axial core positions thereof to be fixed thereto. The detection signals from the encoders 3, 4 are inputted to an angle-of-torsion operation circuit and the angle-of-torsion of the torsion bar 5 between both encoders 3, 4 is operated and the operation result is inputted to a torque operation circuit and a torque value is operated from the angle of torsion and the torsional rigidity of the selected torsion bar 5 to be outputted.

摘要： PURPOSE:To enable the detection of torque even at a stationary time, by providing a light receiving element having one-chip two-element constitution arranged in opposed relation to the light emitting element fixed to one end of a torsion bar and the light emitting element fixed to the other end of said torsion bar. CONSTITUTION:The title apparatus is equipped with a torsion bar 22, the light emitting element 3 fixed to one end of said torsion bar 22, a drive means for driving said light emitting element 3 and a signal processing means for processing the output voltage of the light emitting element 3 to generate output corresponding to torque. The torsion quantity of the torsion bar at the time of the generation of torque is detected as the movement quantity of the light spot on the light emitting element 3 and the signal processing circuit 6 performs signal processing of (V1-V2)/(V1-V2) with respect to two output voltage V1, V2 of the light emitting element. By this method, the detection of torque can be performed even at a stationary time.

摘要： PURPOSE:To obtain an optical torque detector which can detect torque even during the static state by providing a photodetector made of 1-chip 2-element constitution disposed to face a light emitting element and subjecting the two output voltages of the photodetector to signal processing to determine the ratio thereof. CONSTITUTION:This detector is provided with the light emitting element 3 which is fixed to one end of a torsion bar and the photodetector 4 which is made of the 1-chip 2-element constitution and is fixed and disposed to the other end of the torsion bar so as to face the light emitting element. A detection circuit 61 converts the outputs from the respective photodetectors to the output corresponding to the torque by obtaining the ratio thereof. The light emitting spot of the light emitting element is positioned at the center of the dual photodetectors when the torque does not act and therefore the outputs from the dual photodetectors are balanced. The relative positions of the light emitting element and the photodetector change and the outputs from the dual photodetectors are unbalanced if the torque acts. An output difference is then generated and the generated output difference is the signal corresponding to the torque. The ratio of the outputs for the respective photodetectors is obtd. and is converted to the output corresponding to the torque in order to make temp. compen sation.

摘要： PURPOSE:To make it possible to read the graduations of a torque meter even in a rotary state, by allowing the light of a stroboscope emitting light cyclically to irradiate the torque graduations of the torque meter. CONSTITUTION:When a drive motor 16 is driven, the torque meter 11 connected to the motor 16 is rotated and the load apparatus 17 connected to the torque meter 11 is rotated succeedingly. When the output of the drive motor 16 and the load torque of the load apparatus 17 are well-balanced, a stable rotary state is shown. At this time, the torque graduations of the torque meter 11 are transmitted to show a torque value but, because the graduations 12 are rotated, they can not be read. Herein, when the stroboscope 15 irradiating the torque graduations 12 of the torque meter 11 is allowed to generate light at a cycle synchronous to the rotation of the torque meter 11, the graduations 12 appear as though they are stopped and the indicated data can be read.
摘要翻译：目的：即使在旋转状态下，也可以通过使闪光灯的光循环地发光来照射扭矩计的转矩刻度，从而可以读取转矩计的刻度。构成：当驱动电动机16被驱动时，连接到电动机16的转矩计11转动，连接到转矩计11的负载装置17继续旋转。当驱动电动机16的输出和负载装置17的负载转矩良好平衡时，显示出稳定的转动状态。此时，转矩表11的转矩刻度被发送以示出转矩值，但是由于刻度12旋转，所以不能读取。这里，当使频闪仪15照射扭矩计11的扭矩刻度12被允许以与转矩计11的旋转同步的循环产生光时，刻度12看起来好像停止，并且可以读出指示的数据。
