Spur Gear Definition

A spur gear is the simplest and most widely used type of cylindrical gear with teeth arranged parallel to the axis. It is used to transmit power between parallel shafts. Spur gears operate with high efficiency with the teeth directly contacting each other.

Features of Spur Gears

✔ Simple Design - Easy to manufacture and assemble.

High Efficiency - Energy loss is low and torque transmission is high.

Economical - Production costs are low.

Low Side Loads - It applies only radial force, no axial load.

Areas of Use of Spur Gears

- Automotive Industry (Transmission systems)

- Machinery and Industrial Equipment

- Electrical Devices (Drills, printing machines)

- Conveyor Systems and Gearboxes
