2. What is a motion transmission system?
It is a mechanism that transmits motion from one part to another without modifying it. It can perform a rectilinear translation, a rotation or a helical motion.

3. Examples of motion transmission systems
Friction gears
Gear train
Pulleys and belt
Chain and sprocket wheels
Examples of motion transmission systems

4. Friction gears
Friction gears transmit rotational motion through simple rubbing contact (also called friction) between wheels.

5. Example of friction gears

6. Gear train
Made up of small toothed wheels (gears) that transmit rotational motion
Used to increase or decrease the speed of a motion inside a technical object.
The speed of the rotation depends on the size of the gears and the number of teeth that each gear has.

10. Chain and sprocket wheels
Made up of toothed wheels (sprocket wheels) connected by a chain.
