Chain (Transmission of motion) This system serves to connect two toothed wheels sat at a distance and lying on the same plane. It is a flexible device with qualities of resistance and efficiency |
 |
Toothed Rack In this highly efficient mechanism, the crank activates a smaller toothed wheel, which in turn engages a bigger one. As a final point the bigger toothed wheel |
 |
Worm Screw Its concave shaping allows the screw to mesh with more teeth of the wheel at the same time, distributing the force and consequently reducing the risk of breakage |

Ball Bearig for vertical axle This ball bearing reduces the friction of a vertical force like that of a transmission shaft; therefore it can be employed in a wide range of mechanical devices |
 |
Ball Bearig This device anticipates the ball bearing used in the modern mechanism to reduce friction. The system is composed of eight spheres and eight concave - sides spindles |
 |
Flywheel In his notes Leonardo refers to the flywheel as “augmentative wheel” underlining the fundamental quality of such a device. After an initial greater strain, once that |
 |
Room of the mirrors This machine is a result of a long process of Leonado's studies on the optic field. He performed many experiments on lights and shadows and he studied the interaction |
 |
Fantastic Animal Study of a fantastic animal, probably the idea for an automaton.
|
 |
Lantern Pinion This mechanism is very efficient within all sort of devices as it produces the transmission of rotary motion. It is also a flexible system, because it is possible |
 |
Study of Weight This system comprises a series of pulleys and a rope; Leonardo analyses its behaviour and observes that the 33 pulleys hold a 33 pound load and that a one pound |
 |
Tranformation of motion The exploded view clearly explains the way in which this machine operates: how it makes it possible to transform reciprocating motion, imparted to a crank |
 |
Locking System The toothed wheel is extensively employed in a large number of machines and often requires a safety device. This device should keep the wheel from rotating in the |
 |
Mechanism for clock This drawing, realized between the years 1487 and 1505, represents a study that Leonardo made to realize a clock. It is included in the Forster Codex, which is made of two |
