Abstract:
Method for manufacturing a chain drive, comprising:forming shaped pieces (1) having two ends, whereby each end is formed to interlock with an opposite end of another shaped piece (1);connecting several shaped pieces (1) to each other, one after another, at jointing points (N);forming joint pins (x) that are uniform about an axis in the longitudinal direction (p) of the joint pins (x) and have a cross section that extends continuously conically in one direction towards an end of the joint pin;fastening the several shaped pieces (1) to each other at the jointing points (N) to form a chain by inserting a joint pin (x) through corresponding holes formed in opposite ends of the shaped pieces (1), for each interconnection of shaped pieces;securing the joint pins (x) within the holes of the shaped pieces with a locking means (10); andattaching the chain to at least one chain wheel (7), whereby:the conical cross section of the joint pins (x) minimizes bending of the chain along the longitudinal direction (p) of the joint pins (x), when the chain is rotationally driven by the chain wheel (7), to reduce operational wear to the chain.
