mechanical mechanisms
gears
ratchet and pawl
only rotates in one direction
compound gear train
gear size determine speed
chain and sprocket
rotate in the same direction strong
idler gear
used to change direction of rotation
use to fill in gaps between driver and driven gear
rack and pinion
rotate to linear motion
bevel gear
rotate into 45° degrees
spur gear
diference size
worm and worm wheel
very slow
high troque
motors
gearbox
set speed
stepper
expensive
used im CNC
servo
high troque
rotataes through 180° degrees
3v motor
small
ideal for fan
inline
ideal for wheels
rotates 360° degrees
cheap
ratio 120:1
pulleys
stepped pulley
change speeds
regular pulley system
pulley rotate in the same direction
reverse pulley
change direction using the belt
idler pulley
allow for tention on pulley belt
speaker
piezo
ideal for single tones
micro spaker
plays tunes
buzzer
one sound
cams and followers
converts rotational motion to linear motion
straight line movement
many shapes
shape determines movement of follow
linkage
parallel linkage
transfer motion from one point to another
