TURNBUCKLE DAMPENING LINKS

摘要

An elastomeric dampening link including two or more interconnected dampening bushings mounted around corresponding ones of two or more adjustable length turnbuckles linked to devices and elastomeric dampening link includes at least one bar connecting adjacent ones of the dampening bushings. Clamping bands of clamp may be clamped around each of the dampening bushings. Bar may be in tension between the dampening bushings. Each of the turnbuckles may include a rod disposed in a corresponding one of the dampening bushings and having distal hollow internally threaded first end, first eyelet mounted on the first externally threaded shank adjustably screwed into internally threaded first end. One of the bushings may be substantially solid, have a rectangular slot extending inwardly from an annular surface of bushing, and the rod may have six sided surface with two opposite sides slidingly engaging and fitting snugly in the slot. Turnbuckles and links may be used to actuate variable stator vanes.
