Mechanisms: Gears | |
   | Gears (or cogs) are wheels whose perimeter is made up of evenly sized and spaced teeth. The teeth of one cog mesh with those of an adjoining one and transmit rotary motion between the two cogs. The driven cog always rotates in an opposite direction to the driving cog. If both cogs have the same number of teeth, they will rotate at the same speed, however if they have different numbers of teeth then the cog with fewer teeth will rotate more quickly. |
