What Is a Cranked Hinge?

The crank-rocker mechanism refers to a hinged four-bar mechanism having a crank and a rocker. Generally, the crank is a driving member and rotates at the same speed, the rocker swings back and forth for the driven member at variable speed, and the connecting rod makes a plane composite motion. In the crank-rocker mechanism, a rocker is also used as an active member, and the reciprocating swing of the rocker is converted into the rotation of the crank.

The two connecting rods are the hinged four-bar mechanism of the rocker, which is called the double rocker mechanism ^[3] .
