1) Description of Spur Gears
The spur gear is a cylindrically shaped tooth component that is used in industrial plants to transmit
mechanical movements and to control speed, power, and torque. These simple gears are inexpensive,
durable, reliable, and provide constant speed positive drive to facilitate day-to-day industrial operations.
2) Application of Spur Gears
Spur gears are the most easily visualized common gears that transmit motion between two parallel and
coplanar and teeth that are straight and parallel to the shafts. Spur gears are one of the most popular types
of precision cylinders.
