Why are turning gear teeth set at an angle?

Turning gear teeth are set at an angle primarily to reduce noise and vibration during operation. The angled design allows for smoother engagement and disengagement of the gear teeth, minimizing the shock loads that occur when the gears interact. This is particularly important in applications involving large rotating machinery, where excessive noise and vibration can indicate mechanical issues or lead to premature wear of components.

By reducing noise and vibration, the angled teeth also contribute to a more stable and efficient operation of the equipment, which is essential for maintaining the longevity of both the gears themselves and the overall machinery. Additionally, the smoother operation results in less stress on the equipment, leading to improved performance and less maintenance downtime.
