Grashof linkage
WebGrashof Rocker ‐ Rocker (or Double ‐ Rocker) Linkage In this type of Grashof linkage, the shortest link is the coupler (opposite the frame). The input and output links oscillate, and the coupler can make a complete rotation. 47 Norton, Design of Machinery WebAME 352 KINEMATIC FUNDAMENTALS P.E. Nikravesh 1-4 S: denotes the length of the shortest link; L: denotes the length of the longest link; P and Q: denote the lengths of the other two links. The four-bar is Grashof if S + L ≤P+Q This means that at least one of the links can go through a complete rotation; i.e., 360o. The four-bar is non-Grashof if

The Grashof condition for a four-bar linkage states: If the sum of the shortest and longest link of a planar quadrilateral linkage is less than or equal to the sum of the remaining two links, then the shortest link can rotate fully with respect to a neighboring link. See more In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed-chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the … See more Planar four-bar linkages are constructed from four links connected in a loop by four one-degree-of-freedom joints.
