Both straight and spiral bevel gears are used to transfer power between shafts that meet at an angle 90°. The big difference is in the shape of their teeth.
- Straight bevel gears have straight, tapered teeth and are suitable for low-speed applications where noise is not a primary concern. They are simpler to manufacture and more cost-effective.
- Spiral bevel gears have curved teeth that engage gradually, offering smoother, quieter operation and significantly higher load capacity—making them ideal for high-speed or heavy-duty systems. Spiral bevel gears are commonly used in automotive differentials, industrial gearboxes, and aerospace equipment. The curved tooth profile reduces impact loading and vibration, extending gear life. However, spiral bevel gears are more complex and expensive to manufacture.
We can produce both types in per customer requirements, ensure optimal meshing, minimal noise, and long-term performance for bevel gear set.
