The concept of mechanism comes from the Latin word “Mechanisma” which refers to the set of various components or elements designed to ensure the effective functioning of something. Every mechanism is made up of various independent bodies (pieces). It also refers to a piece of a machine. The mechanisms are made up of different components such as: the Link, the Node and the Joint or Kinematic Pair.

The Link: It is the rigid piece that serves for the transfer of movement that gives rise to the movement of the mechanism. The links in turn are divided into two: the mobile links and the immobile links.

Mobile Links: They are those where there is a solid system of bodies; which is made up of moving parts or a set of moving parts.

Immobile Links: They are all the immobile pieces that form a single tense system of immobile bodies.

The Node: It is that part of a link that is used to join another link, and in this way they work together.

The Joint or Kinematic Pair: It is the part that indicates the union of one or more links with each other.

In addition to that, we could classify the mechanisms into different types depending on the study approach that is given, for example:

Mechanisms used to modify the input force.

Mechanisms used to modify the speed.

Mechanisms used to modify movement.

Mechanisms for coupling or uncoupling shafts.,>

Mechanisms that accumulate energy.

Support mechanisms used.

These and other mechanisms can be found, all depending on the approach that you want to give to the term “Mechanism”.
