Presentation Transcript

  1. Gears, Gears, and more Gears James Erath

  2. Spur Gear The “standard” gear, has straight cut teeth, fit only if parallel to each other Examples: Most of the gears included in the Mindstorms set, gasoline engines, bicycle transmissions

  3. Worm Gear Spiraled threads mean that worm gears can be mounted horizontally to spur gears Generally give a high torque/low-rpm conversion Examples: Mills, Mining Equipment, Torsen Differentials

  4. Crown Gear Teeth project 90 degrees out from the side of the gear Used to change direction of power Examples: Rack and pinion, differentials

  5. Rotary to Linear Conversions Rack and Pinion: A gear rotates ontop of a toothed beam and therefore pushes it Examples: Cog Railway, Rack and Pinion Steering

  6. Rotary to Linear Conversions Camshaft: A wheel with a potrusion pushes against a rod, moving it up and down Examples: Gasoline engines, diesel engines

  7. Rotary to Linear Conversions Crankshaft: A gear with a free-moving rod attached to the side of the gear and a moveable rod rotates creating a piston like motion Examples: Gasoline Engines, Diesel Engines, Steam Engines
