before we begin
Before we begin…
  • Pre-assembled Lego materials SHOULD NOT be taken apart.
    • Lego Gripper, Steering Assembly, Differential Assembly
  • Disassembling any of the pre-assembled examples will result in a 10-point deduction on your lab report grade.
  • Follow directions! Only take objects apart when told to and when you have put them together to begin with.

gear definition
Gear: Definition
  • A gear is a wheel with teeth along its rim.
  • It is used to transmit effort from one shaft to another.

Autumn Quarter

gear train
Gear Train
  • Combination of two or more meshed gears. Used to change the rate of rotation, the direction of rotation, and the amount of torque.

Autumn Quarter

gear ratio
Gear Ratio
  • Gear ratio is also called “Mechanical Advantage”

Autumn Quarter

types of gears
Types of Gears
  • Spur gears
  • Worm gear
  • Rack and pinion
  • Bevel gears

Autumn Quarter

spur gears
Spur Gears
  • Simplest
  • Most widely used in Instrumentation and Control Systems
  • Used to drive parallel shafts

Autumn Quarter

spur gear terminology
Spur Gear Terminology
  • Pitch circle diameters
  • Size of teeth (Diametral pitch)
  • Center distance
  • Number of teeth
  • Pinion
  • Gear

Autumn Quarter

worm gears
Worm Gears
  • Used to change speed and direction of rotation.
  • Used for connecting skew shafts (usually 90 degrees)
  • High gear ratios.
  • Higher load capacity.

Autumn Quarter

rack and pinion
Rack and Pinion
  • Used to convert rotational motion into linear motion, or vice-versa.

Autumn Quarter

bevel gears
Bevel Gears
  • Used for intersecting shafts.
  • Most transmissions occur at right angles but shaft angles can be any value.

Autumn Quarter

sprockets
Sprockets
  • Gears are connected by a chain instead of directly.
  • The input and output shaft rotations are in the same direction.
