초록

This is an experimental study where the coefficient of friction between engine pulley and V-Belt is obtained. The experimental method is applied pulleys made of existing steel and aluminium materials. The relative friction workpiece is a v-belt incorporating rubber with cloth. The friction test uses a pin-on-disk friction modulator and measures the coefficient of friction depending on the number of revolutions in the disc. As a result, in the case of aluminum material, there was a sliding phenomenon because the coefficient of friction was small when accelerating and decelerating. Also, the variation of the friction coefficient was severe when the rotation speed was increased or decreased. Therefore, it is considered that the aluminum pulley is slippery even if it is fit to the structural rigidity. Therefore, in order to secure a stable friction coefficient, the pulley groove surface will be surface-treated, a special alloy is added, or a heat treatment is required.
