Spur gears are the most common type of cylindrical gear, featuring straight teeth parallel to the axis of the mounted shaft. This simple design offers several key advantages:
- No Axial Thrust: Because the teeth are straight, they do not generate any thrust force along the shaft axis, simplifying bearing requirements.
- High Precision: The straightforward tooth form allows for economical and highly precise manufacturing.
- Positive Drive: They provide a constant speed ratio without slippage, ensuring reliable power transmission.
