Apparatus for torque measurement on rotating torque shafts |
摘要 |
Torque measurement is required in motors, in particular. It is already known to generate response signals in an axially offset manner at least at two points on a torque shaft by irradiating light onto the rotating torque shaft. An azimuthal offset of those signals produced by the torque over and above a rotary movement must be determined for evaluation purposes. An apparatus according to the invention for torque measurement on rotating torque shafts uses a continuous light beam to generate signals. A torsion-induced deflection of the light beam is geometrically amplified before an evaluation and an azimuthal offset is determined accurately therefrom as a time signal. The apparatus includes a device for generating optical response signals from at least two axially offset reflector systems at the torque shaft of the machine, which have individual concave mirrors in each case.
