High-Precision Spiral Bevel Gear with ISO 4-6 Grade Accuracy and Carburization

Product Specification

Spiral Bevel Gear  - High-Precision Right-Angle Transmission Solution

Spiral Bevel Gears are engineered for high-performance power transmission between intersecting shafts, typically at a 90-degree angle. Featuring curved, oblique teeth, these gears offer a smoother, quieter, and more efficient alternative to straight bevel gears. Manufactured using world-class equipment (such as Gleason or Klingelnberg systems), they are the ideal choice for heavy-duty and high-speed industrial applications.

Key Features & Benefits

• Superior Load Capacity: The curved teeth provide a larger contact surface area, allowing for significantly higher torque transmission and better load distribution.

• Low Noise & Vibration: Gradual tooth engagement ensures smooth operation, drastically reducing "gear whine" and mechanical vibration even at high RPMs.

• High Efficiency: Optimized tooth profiles achieve a transmission efficiency of up to 97%–98%, minimizing energy loss.

• Enhanced Durability: Made from premium alloy steels (e.g., 20CrMnTi, 8620, 18CrNiMo7-6) and precision-hardened (Carburizing & Quenching) to HRC 58-62 for maximum wear resistance.

• Precision Finishing: Available in Lapped or Ground finishes to meet international standards (DIN 3965 / AGMA 2000).

Applications

Our spiral bevel gears are indispensable in industries where reliability and precision are critical:

• Automotive: Differential systems, rear axle drives for trucks and SUVs.

• Aerospace: Helicopter transmissions and auxiliary power units (APU).

• Industrial Machinery: Right-angle gearboxes, robotics, printing presses, and CNC machine tools.

• Energy & Mining: Wind turbine pitch drives, heavy-duty crushers, and marine propulsion.

• Agriculture: Tractor PTO drives and harvester gearboxes.
