Gears are often used in machines to increase force or speed. A lesson on how gears work and which machines use … With the potential to change the direction of force and the operating angle of machinery, a bevel gear has many different applications. By the way, there's actually a seventh simple machine which is gears. Genetics. In his book, Elements of Machines , Leonardo DaVinci listed twenty-two different simple machines. Sciencing_Icons_Cells. A gear is a wheel and axle that has teeth along the wheel. Sciencing_Icons_Molecular. A gear is just a wheel with teeth, sometimes called a cog. Molecular.

The size of the gear determines the speed at which it rotates. If you want to pedal up a hill, you use gears to increase your force so you don't have to work quite so hard, although the catch is that they reduce your speed at the same time. Basic Gear Mechanisms: Cars, clocks, and can openers, along with many other devices, use gears in their mechanisms to transmit power through rotation. Instead of touching directly and rotating in opposite directions, each pair of gear wheels is connected by a flexible metal chain (kept taught by a springy lever and gear-shifting mechanism called a derailleur), so they turn in the same direction; technically, gears linked this way are called sprockets. Bevel gears use different numbers of teeth to increase speed.
