Advanced Helical Tooth Design for Reduced Noise and Enhanced Load-Bearing Capacity in Spiral Bevel Gears

1. Description of Spiral Bevel Gear

Spiral bevel gear is a type of gear used to transmit rotational motion and power between intersecting shafts.

Its tooth surfaces are helical in shape, making it widely employed in automotive, aerospace, and industrial transmission equipment.

2. Features and Advantages of Spiral Bevel Gear

• Helical tooth design: The tooth profile follows a spiral path, enabling gradual contact transition from one end to the other during meshing. This results in smoother transmission and reduced noise levels.
• High overlap ratio: More teeth engage simultaneously than in straight-toothed bevel gears, enhancing load-bearing capacity and suitability for high-torque applications.
• Adjustability: Axial fine-tuning optimises the contact area, accommodating installation errors or load-induced deformation.

3. Applications of Spiral Bevel Gear

• Automotive differentials: such as rear axle main reduction gears, transmitting power to the wheels.
• Helicopter transmission: connecting the turbine shaft to the rotor shaft within the main reduction gear.
• Industrial equipment: 90° steering transmission for heavy-duty machine tools and mining machinery.
