Mechanical Mechanisms
gears
spur gear
difference sizes
bevel gear
rotates through 45 degrees
rack and pinion
rotation to linear motion
chain and sprocket
rotates in same direction. strong
ratchet and pawl
only rotates in one direction
compound gear train
gear sizes determines speed
idler gear
used to change direction of rotation
used to fill in gaps between driver and driven gears
worm and worm wheel
high torgue
very slow
motors
inline
ratio 120.1
cheap
rotates 360 degrees
ideal for wheels
servo
high torque
rotates through 180
gearbox
set speed
stepper
expensive
used in cnc
3v motor
small
ideal for fan
Pulleys
Stepped pulley
change speeds
Reverse Pulley
change direction using the belt
Regular pulley system
pulleys rotate in same direction
Idler pulley
allows for tension on pulley belt
cams and followers
many shapes
shape determines movement of follower
converts rotational motion to linear motion
straight line movement
follower shape determines accuracy
Speakers
Buzzer
One sound
Piezo
Micro Speaker
Linkage
Transfers motion from one point to another
Parallel Linkage
