PPT-Gears Gears A gear is a wheel with teeth that mesh together with other gears

Gears A gear is a simple machine like a lever The larger the diameter of the gear the longer the lever What are Gears used for Ensure positive motion Reverse the direction of rotation Increase or decrease the speed of rotation. BASE DIAMETER D is the diameter of the base cylinder from which the involute portion of a tooth profile is generated BACKLASH B is the amount by which the width of a tooth space exceeds the thickness of the engaging tooth on the pitch circles As ac 15: Helical, Bevel, and Worm Gears. Just stare at the machine. There is nothing wrong with that. Just live with it for a while. Watch it the way you watch a line when fishing and before long, as sure as you live, you'll get a little nibble, a little fact asking in a timid, humble way if you're interested in it. That's the way the world keeps on happening. Be interested in . Nanotechnology Simple Machines. Gears, Pulleys, & Sprockets. These three power train elements transfer energy through rotary motion. .
