WebDec 4, 2024 · The four-bar linkage is a planar mechanism of four rigid members: a frame, an input link, an output link, and a coupler link. Four revolute pairs connect these members, forming a closed-loop kinematic … Planar four-bar linkages are constructed from four links connected in a loop by four one-degree-of-freedom joints. A joint may be either a revolute joint – also known as a pin joint or hinged joint – denoted by R, or a prismatic joint – also known as a sliding pair – denoted by P. A link that are fixed in place relative … 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 quadrilateral linkage, RRRR or 4R linkages have four rotating joints. One link of the chain is usually fixed, and is called the ground link, fixed link, or the frame. The two links connected to the frame are called the grounded links and are generally the input … See more A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint.
