扭矩试验台的改造及扭矩电测摘 要：机械传动试验台是用试验的方法研究机械传动的各种失效形式并测定其承载能力、传动效率及有关性能的基本手段，长期以来我国的传动试验台的研制基本上还停留在传统的人工方式水平上。这些试验台都存在一个共同的缺点：自动化程度低，无法模拟实际工况对各种机械传动产品进行试验，试验过程的监控及试验数据的采集和处理都较麻烦且准确性低。近些年来的研究取得一些进步，但目前的绝大多数实验台还只能进行恒定载荷加载或简单的程序控制阶梯加载，实验结果与现场测试依然有较大的差距。 本文提出改进机械原理实验室的齿轮试验台的方案，在成本不高的情况下，增加其测试功能-可以测量联轴器，离合器，带传动的效率和寿命，使其成为一台多功能机械传动试验台。关键词：机械传动；齿轮；联轴器；扭矩传感器 The Transformation of Torque Test Rig and Torque MeasurementAbstract: Mechanical transmission experiment platform is a basic device for the study of some types of mechanical failure,the transmission efficiency, and the related performance of mechanical transmission and the measurement of the load ability. In our country, the ability of studying and designing mechanical transmission experiment platform is still at such stage that the experimental device is operated manually, leaving some common shortcomings among those platforms,such as low-automation because they cant simulate real working environment accurately during testing the mechanical products, and the accuracy of acquiring data is low. Although a number of achievements have been made in recently years, these platforms can just perform with invariant load or with simple skip load. There is a big gap between experiments and real working environment.This paper presents improved mechanical principle of the laboratory test gear program,the costs are law in the circumstances, increase its test function can be measured coupling clutch, belt drive efficiency and lifespan, as a multifunctional mechanical
