Abstract
A method is disclosed of manufacturing a pulley with integral bearing comprising a sheet metal pulley mounted on the outer race of a bearing. The pulley is a close sliding fit on the outer race. The interstice between the pulley and the race is at least partly filled with a low-melting-point filler metal which, when heated, melts and diffuses by capillary action into the interstice between the pulley and the race, at least partly filling the interstice and fastens the pulley to the race when it solidifies. The filler metal is advantageously a brazing alloy having a melting point much lower than that of the parts to be joined together. Applications of the method include the manufacture of belt tensioning pulleys with integral bearings, as used on automobile vehicle engines, for example.
