Rotate speed torque transducer photo generator

The utility model belongs to a photoelectric signal generator on a sensor, which is used for measuring the running speed and the running torque of a shaft. Various devices for measuring the running speed and the running torque in the prior art have the defects of large abrasion, short life, complex structure and difficult processing, and does not fit the high speed measurement. In order to overcome the defects, the photoelectric signal generator provides the following technical scheme: the photoelectric signal generator of a running speed and running torque sensor comprises an elastic shaft. A plurality of reflex streaks in the same shape are evenly coated with reflex materials on symmetrical positions on the outer circumference surface of the both ends of an elastic shaft in the shell of the sensor. Installation panels are fixed on the shell corresponding to the reflex streaks at the both ends of the shaft. The same position on the installation panels is fixedly provided with CD driver laser heads which are connected with a measuring circuit. The running speed and the running torque are measured through picking the reflex signals of the reflex streaks at the both ends of the shaft by the CD driver laser heads, so the photoelectric signal generator has the advantages of simple structure, easy processing, no abrasion and long service life. The photoelectric signal generator on a sensor is suitable for high speed measurement.
