磁力金属带传动的试验研究

Experimental Study on Metal Belt Drive with Magnet

磁力金属带传动(MBDM)是基于柔性体摩擦传动理论和电磁学理论而构建的一种新型摩擦传动。本文通过试验,验证了MBDM的力学机理,测定了传动效率及弹性滑动率等相关性能参数。结果表明,MBDM是利用磁场吸引力和初拉力的耦合作用产生摩擦力而传递运动和动力的,其传动效率可稳定在95 %～98% ,最高可达99.5 % ,而弹性滑动率一般在0 .1%以下。

Based on the theories of flexible friction drive and electromagnetism,a new friction drive,metal belt drive with magnet(MBDM),is proposed.The transmission mechanism of MBDM is validated and some performance parameters,such as transmission efficiency and elastic creep ratio,are measured by test.The results show that MBDM mainly depends on the coupling action between magnetic attraction and initial tension to transfer movement and power.The transmission efficiency of MBDM is about form 95%to 98%,but the elastic creep ratio is below 0.1% in general.
