• Cylindrical Gears > Spur Gear
- No axial thrust, can be mounted with simple bearings
- Good at moderate speed, noisy at high speed
Spur gear is the simplest type of gear. The lead angle is parallel to the axis of rotation. Spur gears are meshed in parallel without axial thrust and are considered to be excellent at moderate speeds but tend to be noisy at high speeds. Spur gears are easy to manufacture and can be made in high precision.
