Several different technical objects are made up of parts that play a role in their function or construction, called "organs". Sometimes the movement of one organ causes the movement of another.
More precisely, the movement of a driving member can cause the movement of a driven member.
There are three types of mechanical movements:
• Linear translational motion: moving in a straight line
• Rotational motion: turning around a straight axis
• Helical motion: turning and moving along a straight axis
When the driving member causes the movement of a driven member of the same type (for example, a linear translational movement that causes another linear translational movement), the system of parts is a motion transfer mechanism. The driving member and the driven member (and the intermediate members, if any) can be referred to as part of a motion transmission mechanism.
When the driving member causes the movement of a driven member that isn’t of the same type (for example, a linear translational movement that causes a rotational movement), this is a transformation of the movement. The driving organ and the driven organ (and the intermediate organs, if any) can be referred to as part of a motion transformation mechanism.
Here are some examples of motion transmission mechanisms:
