Q. What is Gear and their types?

Question

Accepted Answer

Gears are mechanical components that transmit power and motion between rotating shafts. There are various types of gears.

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 and have high gear reduction ratios.
Gears are essential components in many mechanical systems, including automobiles, industrial machinery, and robotics.
