摘要
扭矩测量是传动线路中的重要内容之一,高精度、高稳定性的非接触式扭矩测量方法是当今各国机械量测量研究的热点之一,为此,提出了一种基于螺管形差动变压器的非接触式扭矩传感器的研究。系统介绍了该测量方法的原理与结构。经实验证实该测量原理可行,所设计的扭矩传感器具有较好的线性度和一致性,重复精度0.5%。
The torque measurement is one of important contents of transmission line. lne non-contract torque measuremem method with high precision and high stability is one of hotpots that research machine quantity measuremem in various countries today. Therefore, research on a non-contract torque sensor based on screw-type differential transformer is put forward. The principle of this measurement method and relative structure are introduced. The experiment results show： the measurement principle is feasible; the designed torque sensor has better linearity and consistency; repeatability precision is less than or equal to 0.5%.
