Roller chain link plate profile

摘要

A roller chain assembly has material added to the location on the link plate (250) face where fatigue failure is most likely to occur. This location is typically within a sector defined by a line extending radially from the aperture center in a direction perpendicular to the line connecting the two aperture centers and an imaginary line extending from the same aperture center toward the link plate end section at an angle of 30-45 degrees. The added material increases the strength of the link plate, allowing for the use of inner links having larger bushings.
