Claims

[Scope of utility model registration request]

A torsion shaft is inserted between a driving machine and a driven device, and the driving torque is determined by detecting the torsional angular displacement at both ends of the torsion shaft via a torsion tube coaxially fixed to the torsion shaft. In the measuring device, a pair of parallel optical disks are provided with the same number of notches or through holes at equal pitches along the circumference, each is fixed to both ends of the torsion shaft via a torsion tube, and faces each other in close proximity. a circuit that projects light onto one side of the parallel optical disk; a light receiving circuit that receives the light that has passed through the notch or through hole of the parallel optical disk and generates an electrical signal according to the amount of received light; An optical torque measuring device comprising: an arithmetic circuit connected to the light receiving circuit and calculating torque based on an electric signal when no torque is applied and an electric signal when a torque is applied.
