OPTIMIZATION OF WEIGHT OF ROLLER CHAIN INNER LINK PLATE FOR TYPICAL INDUSTRIAL CHAIN APPLICATION

Optimization is the process of obtaining the best result under given circumstances in design of system.In optimization process,we can find the conditions that give the maximum and minimum value of function.In this study,a weight optimization process is used for the design of roller chain link for minimization of failure modes.This process has various design variables,such as wall thickness of link,breaking area of link,inn er width of chain and shape of the link.While deciding the optimized weight of the roller chain link,raw material plays important role,so it is necessary to decide raw material.Normally medium alloy steel i.e.as per Indian Standard C45,55C8 or as per British Standard EN19 has been used in normalized condition and after manufacturing of link it has been heat treated up to 35 to 40 HRC in order to get tensile strength up to 70 to 80 kg/mm�
