Construction of Traction Characteristic Prediction Formula and Experimental Verification at 50000 rpm

Abstract

To clarify the transmission characteristics of a traction drive operating at a high rotational speed, the traction coefficient for an actual drive was measured and was found to decrease by 20% at 50000 rpm. Therefore, a traction model was created to design a roller with a higher traction coefficient. Empirical equations were derived to represent the three characteristic values required for the model. By adjusting the coefficients in the equations to match the measured values of the traction coefficient, the traction coefficient could be predicted with a maximum error of 7% regardless of the conditions.
