【摘要】 针对目前转矩转速传感器高速工况测量困难的问题,研究了一种高速光电反射式转矩转速传感器。采用比相测量原理,以激光头和反光条纹为信号发生器。计算了弹性扭轴的结构参数和临界转速,并进行了样机台架实验。实验表明:该传感器结构简单、性能稳定,与现有的转矩转速传感器相比,该传感器可用于速度在105r/m in以上的超高速回转机械(如航天叶轮泵、高速轴承等)转矩转速的测量,且测量误差小。更多还原

【Abstract】 It is difficult to measure torque and speed of high speed rotating machinery,a new type of high speed photo-electric reflective torque and speed sensor is presented in this paper.The system utilizes the measurement theory of phase comparison and uses a laser head and reflecting fringes as the signal generator.The parameters and critical speed of the flexible shaft are calculated.The designed sensor is also tested on test bench.Test results show that the sensor is simple in structure,stable in performance,and it can measure rotating shafts with a rotation speeds up to 105 r/min,and it also has a smaller measurement error compared with current apparatus for speed and torque measurement.更多还原
