ABSTRACT:
A chain link 1 assembly body includes a pre-molded resin sleeve having a uniformly cylindrical inner periphery and a partially convexly contoured outer periphery, a bushing conformed to the shape of the sleeve and inner links each having a bushing press-fitted hole for fitting around the ends of the bushing. The method includes the step of providing an engineering plastic resin sleeve and a bushing. The sleeve is pre-molded to have a uniformly cylindrical inner periphery and an outer periphery having a convex contour for a central portion of the sleeve and uniformly cylindrical contours for the opposed ends of the sleeve. The bushing is originally uniformly cylindrical prior to its ends being press-fitted into bushing press-fitted holes of inner links. The sleeve is inserted in the bushing while the bushing is uniformly cylindrical in cross-section due to not having either of its ends press-fitted into bushing press-fitted holes of inner links (first embodiment), non-uniformly cylindrical in shape due to having one of its ends press-fitted into the bushing press-fitted hole of an inner link (second embodiment), or partially convexly contoured due to having both of its ends press-fitted into bushing press-fitted holes of inner links (third embodiment).
