Patent ID: 7350438

Claim:
A method of producing a connecting member comprising: selecting a connecting member main body having a first end with a first pin hole and a second end with a first large end part forming a first portion of a second pin hole; selecting a cap to be arranged on the second end of the connecting member main body with a second large end part forming a second portion of the second pin hole such that the second pin hole lies between the connecting member main body and the cap, and selecting a bolt serving to fasten the connecting member main body and the cap together, the bolt being selected by calculating a bolt strength safety factor based on an axial strength limit load of the bolt and a maximum load that will be born by the bolt due to an inertia force acting on the connecting member; calculating a mating surface separation safety factor based on a tensile load resulting from the inertia force and a maximum bolt load carried by the bolt at a mating surface separation limit in which the connecting member main body and the cap remain in contact without separating; and selecting the mating surface separation safety factor that is equal to or larger than the bolt strength safety factor.
