Mechanical Mechanisms
Gears
Worm and Worm Wheel
High torque
Very slow
Spur gear = Difference sizes
Bevel gear = Rotates through 45 degrees
Ratchet and Pawl = Only rotates in one dicrection
Rack and Pinon = Rotates to linear motion
Chain and sprocket = Rotates in same direction, Strong gear
Compound gear train = Gear size determines speed
Idler gears
Used to change direction of rotation
Used to fill space between driver and driven gears
Motors
inline
Cheap
Ratio 120:1
Rotates 360 degrees
ideal for wheels
Servo
Rotates through 180 degrees
High torque
Stepper
Expensive
Used in CNC
Gearbox
Set Speeds
3v Motor
Ideal for fans
Small
Pulleys
Stepped Pulleys = Changes Speed
Regular Pulley Systems = Pulleys rotate in the same direction
Reverse Pulleys = Changes Speed
Idler Pulleys = Allows for tension on pulley belt
Cam and Follower
Follower shape determines accuracy
Shape determines movement of follower
Converts rotational motion into linear motion
Straight line movement
Speakers
Buzzer = One Sound
Piezo =Used for single tones
Micro Speaker = Play tunes
Linkages
Parallel Linkage = Transfers motion from one point to another
