Question

Accepted Answer

There are various types of gears such as spur, helical, bevel, worm, rack and pinion, etc.

Spur gears have straight teeth and are used for low-speed applications
Helical gears have angled teeth and provide smoother operation at higher speeds
Bevel gears are used to transmit power between shafts that are at an angle to each other
Worm gears are used for high reduction ratios and are self-locking
Rack and pinion gears are used to convert rotational motion into linear motion
Planetary gears are used in automatic transmissions and provide high torque capacity
Epicyclic gears are used in wind turbines and provide high efficiency
Hypoid gears are used in automotive differentials and provide high torque capacity
Spiral bevel gears are used in heavy-duty applications and provide high strength and durability
