mechanical mechanism
gears
worm and worm wheel
high troque
very slow
ideal gear
used to fill in gaps between driver and driver gear
used to change direction of rotation
compund gear train
gear sizes deter mine speed
ratchet and pawl
only rotates in one direction
chain and sproclhet
rotates in same postion strong
spur gear
different sizes
rack and pinion
potation to linear motion
bevel gear
rotates throught 45 degrees
motors
inline
ideal for wheels
cheap
ratio 120.1
seno
rotates through 180
high trouque
stepper
used in cnc
expensive
3v motor
ideal for fan
small
gearbox
set speed
pulleys
stepped pulleys
changes direction using the belt
regular pulleys system
pulleys rotates in the same direction
reverse pulleys
changes speeds
idear pulleys
allows for tension on pulleye belt
cases and followers
straight fine movements
followers shape determines accuracy
coverts rotational motion to linear motion
many shapes
shape determinds movements of followers
linkage
parallel linage
transfers motion from one point to another
