METHOD FOR EVALUATING BONDING STRENGTH OF PULLEY MADE OF RESIN

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating the bonding strength between a bearing and a pulley main body made of resin of a pulley made of a resin in which the pulley main body is insert-molded to the outer circumferential surface of the outer ring of the bearing.;SOLUTION: The bonding strength between the bearing and the pulley main body of is determined on the basis of the heating process for heating the pulley made of resin, which is formed by the insert-molding of the pulley main body made of resin to the outer circumferential surface of the outer ring of the bearing, at the oxidation temperature of the bearing and changes in color of the outer circumferential surface of the outer ring to which the heating process has been applied due to the oxidation.;COPYRIGHT: (C)2009,JPO&INPIT
