数字式扭矩传感器技术性能及应用

北京东燕郊冶金一局超硬材料研究所 李国林 (高级工程师)

摘 要:本文介绍了数字式扭矩传感器原理结构,该方式利用两组环形

变压器非接触地传递能源及信号,克服了集流环及无线电遥测的一系列

问题,本传感器体积小便于安装,精度高、抗干扰性强.已取得五项国家

专利.

关键词:传感器,扭矩,环形变压器

Compress: This article introduces theory and frame of digital

moment of force sensor. This mode untouched passes energy sources

and signal with two group of annular transformer .It conquers a

series of problems about circle current and wireless remote

sensing. This sensor’s volume is small and easy to install. Its

performance against disturbance is better and precision is higher. It has already achieved five-item national patent and CMC

production license and achieved national emphases new product

certificate, which was promulgated by national five ministries

and office in 1998.

一 前言

在旋转动力系统中最频繁涉及到的参数:旋转扭矩,为了检测旋转扭矩

传统使用较多的是扭转角相位差式传感器,该方法是在弹性轴的两端安
