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 to the … 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 joints … 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 … See more A slider-crank linkage is a four-bar linkage with three revolute joints and one prismatic, or sliding, joint.

WebA spherical four-bar mechanism consists of four links connected by four revolute joints (pin or hinge joints). A body undergoing spherical motion has three degrees of freedom. The degrees... WebAug 21, 2024 · The R-pair axes of a spherical 4R mechanism all intersect at the centre of the sphere. Those of a planar 4R mechanism are all parallel; they can be thought of as intersecting in a common point at infinity of the projective extension of the Euclidean plane of the planar 4R.
WebAn example of a simple closed chain is the RSSR spatial four-bar linkage. The sum of the freedom of these joints is eight, so the mobility of the linkage is two, where one of the degrees of freedom is the rotation of the coupler around the line joining the two S joints.
