Wherever you want to change how fast something turns and how strong something turns. Gears allow you to change a slow and strong movement into a faster but weaker movement, or the other way around. Gears can also be used to change the direction of rotation.
gears are used to transmit power and motion
Planetary gears can be spur or helical gears.
There are gears in my can opener, my mixer, and my food processor.
mostly helical gears !1.
Wherever anyone wants a chance to trade speed for power, or the other way around.
yes
There are three main types of gear combinations used in mechanical systems: spur gears, helical gears, and bevel gears. Spur gears have straight teeth and are used for simple applications. Helical gears have angled teeth for smoother operation and higher loads. Bevel gears have cone-shaped teeth and are used to change the direction of rotation.
Gears are used to make pieces of items or objects rotate. They are used in a majority of machines available.
Bevel gears can be used to change the direction of drive in a gear system by 90 degrees
Depends on its condition. I think it'd be around $30-$35 for a used one.
