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.
