INSIEME DI DUE PEZZI CONCENTRICI ASSEMBLATI PER IMMANICATURA

摘要

A hub and web assembly such as for a clutch plate or pulley half in which the outer component comprises a sleeve with a web and the inner component a hub. The inturned terminal end of the sleeve bears axially against a transverse shoulder to positively determine the relative axial position of the components. Also, a bead formed from the inner component is swaged against the opposite side of the inturned terminal end. The length of the serrations on the sleeve is shorter than the total length thereof. A cylindrical bearing surface on the end of the sleeve adjacent the actual web bears tightly against a corresponding cylindrical bearing surface on the hub remote from the transverse shoulder. This arrangement permits limited torsion of the web without loosening the mating serrations on the components.
