A STUDY OF V-BELT DRIVE MECHANICS OF SLIDING FRICTION WITH TWO SYMMETIUC PULLEYS
V-belt is a special heterogeneous material,its material and pulley groove structure makes the V-belt drive mechanics complicated.The elasticity limit.seating and unseating effects.indial compliance makes us consider the macro features of the drive and not to consider the material heterogeneity.We focus on the steady mechanics of V-belt drive in the state of sliding friction between groove and belt.The pulley groove leads to two.dimensional radial and tangential friction forces whose direction depends on the relative speed between belt and the pulley along the contact arc.The belt model is analyzed with comparing method which is performed through acquiring the equivalent coetiicient of friction.and replacing the coefficient of friction in the flat belt mechanical equilibrium equations for v-belt analysis.Through the sample calculation it is proved that this method is simple and valid for V-belt mechanical analysis.
