The belt drive transfering power and motion by regarding flexible body as the intermediate element

it is composed of the drive and the driven pulley Installed in parallel shaft and the pulley wrapping around with flexible body

and widely used in industrial and agricultural production.Friction belt drive has the phenomenon of unsteady

dynamic tension spread

elastic slip and skid.Firstly

these characteristics of belt drive are analyzed from theoretically

then

the drive process simulation of multi-row V belt drive is carried out based on RecurDyn

the relevant dynamics and kinematics curves are got

a reference for the design and calculation of multi-row V belt is provided.
