Transferring torque with LEGO pieces is possible not only
with gears and axles but also with two additional systems:
pulleys and chains. All of these systems work with similar
principles.
LEGO pulleys are wheels that can be connected via
strings or rubber bands, allowing for the transfer of drive
and movement. You’ve seen similar pulleys in “belt” systems
in real life. Pins without friction, bushes, and other circular
elements can also be used as LEGO pulleys. A pulley system
is particularly useful for lighter loads, transferring drive
silently and over a long distance.
LEGO chains work similarly, though they’re better suited
for higher torque than a pulley. A chain replaces the rubber
band of a pulley system, and gears replace the pulleys. The
driver gear in a chain is known as a sprocket, just as in a
tracked vehicle. Instead of being held by the frictional force
of a string or rubber band, a chain is held by meshing its
links with gears. Figure 6-1 shows the pulley and chain
systems side by side.
