<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a power transmission chain, which can determine a preliminary tension load necessary for increasing durability, as a numerical target. <P>SOLUTION: A target stress Ps is obtained by the relation σy×α, wherein a proof stress of link material is represented by σy, while a shakedown coefficient is represented by α and assuming α=1.5-2.1, and based on the relation between the preliminary tension load and a stress, the preliminary tension load F is obtained so that the target stress Ps can be obtained. The obtained preliminary tension load F is imparted in a preliminary tension process. <P>COPYRIGHT: (C)2012,JPO&INPIT |
