What is gear and its types?

Question

Accepted Answer

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

Spur gears are the most common type and have straight teeth.
Helical gears have angled teeth and provide smoother operation.
Bevel gears transmit power between shafts that are not parallel.
Worm gears have a screw-like thread and are used for high reduction ratios.
Planetary gears have a central gear that rotates around other gears.
Rack and pinion gears convert rotational motion into linear motion.
Internal gears have teeth on the inside of the ring and are used for compact designs.
Miter gears are used for right angle power transmission.
Epicyclic gears are used in automatic transmissions and have complex motion.
Hypoid gears are similar to spiral bevel gears but have offset shafts.

Accepted Answer

Gear is a toothed cylindrical or roller shaped element of machine that meshes with another toothed cylindrical element to transmit powerful one shaft to another.
