Gears are used to transmit power and motion between rotating shafts
They are classified into various types such as spur, helical, bevel, worm, etc.
Spur gears are the most common type and have straight teeth that run parallel to the axis of rotation
Helical gears have angled teeth that run at an angle to the axis of rotation, resulting in smoother and quieter operation
Bevel gears are used to transmit power between shafts that are at an angle to each other
Worm gears are used to transmit power between shafts that are at right angles to each other
Planetary gears are used in automatic transmissions and have multiple gears that rotate around a central gear
Gears are essential components in many machines and devices, including cars, bicycles, and watches
