REal Life ELA APPLICATIONS
Two toothed wheels fit together either directly or through a chain or belt so one wheel will turn the other. Some gears may have a screw or a toothed shaft in place of one of the wheels. A gear may also be a combination of toothed wheels that produces a certain speed (such as a bicycle's top gear which makes the bike go fast, and the low gear for slow speed.)
POEM GEARS
The gearing made for hills like these
On my bike I find gears equal freedom’s melody
Despite the calls for engines to persist
I cannot ignore the chain’s soliloquy
Push me and I’d stretch
Greese me and I’d go silent
Find me between the road and your toes
And leave your concerns at the door
I’m the keynote to freedom’s rhythms
At at this hill I emplore
Stop for a second and shift into a new reality.
Gears are used in tons of mechanical devices. They do several important jobs, but most important, they provide a gear reduction in motorized equipment. This is key because, often, a small motor spinning very fast can provide enough power for a device, but not enough torque. For instance, an electric screw driver has a very large gear reduction because it needs lots of torque to turn screws, but the motor only produces a small amount of torque at a high speed. With a gear reduction, the output speed can be reduced while the torque is increased.
Advantages
1. It transmits exact velocity ratio.
2. It may be used to transmit large power.
3. It may be used for small centre distances of shafts.
4. It has high efficiency.
5. It has reliable service.
6. It has compact layout.
