Four-bar linkage - Wikipedia
The slider-crank linkage (RRRP) is one type of arrangement such that one link is a crank, which is then connected to a slider by a connecting rod. The inverted slider-crank is another type of arrangement such that there are two cranks with a slider acting as the coupler. See more

- In a four bar linkage, if the shorter side link revolves and the other one rocks (i.e., oscillates), it is called a crank-rocker mechanism1. In a four bar linkage, if both of the side links revolve, it is called a double-crank mechanism1. The crank-rocker converts full input rotation into a re-rocking output, while the double-crank linkage converts uniform full-rotation input into a full, but non-uniform, rotational output2.Learn more:✕This summary was generated using AI based on multiple online sources.
