PPT-What Are Gears? What Do They Do?

What is a gear List as many examples as you can of gears or objects that use gears 2 PreLesson Quiz What is a gear A gear is a wheel with teeth that meshes together with other gears and is usually made of metal or plastic. 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 5 North Stiles Street PO Box 1063 Linden NJ 070360001 8003442241 9088629300 8002271979 FAX wwwnevastanecom Nevastane SS 46 Nevastane SL 32 46 68 Nevastane SS 100 Nevastane SL 100 150 Nevastane AW 22 32 46 Nevastane EP 100 1000 Nevastane SL 100 Students will learn how to use gears properly efficiently and effectively Predicting directional motion of a string of gears Class discussion of different building methods Explorin g gear setups gear ratios and directional changes Recording design a Weve already invested more than 19 of our gross sales this year in new machines says Mr Young After all the machines were buying give us a tremendous edge when competing for new business We can do things no one else can do What better way to compete Nanotechnology Simple Machines.

Gear pumps are a ubiquitous means to generate hydraulic power. Rugged simplicity, cost effective. The simplicity of gear pump design presents some liabilities. 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.
