1) Description of Spiral Bevel Gear

Spiral bevel gears are an efficient power transmission device, suitable for the transmission tasks between intersecting shafts. Their tooth profile adopts a helical curve design, which compared with the traditional straight bevel gears, has more stable meshing characteristics and higher load-bearing capacity.

2) Features of Spiral Bevel Gear
Spiral bevel gears achieve power transmission between two intersecting shafts (usually at a 90° angle) through helical tooth surfaces. During the transmission process, the tooth surface contact gradually expands from local to full contact, effectively reducing impact and noise and enhancing the smoothness of the transmission.
a) Low noise and high smoothness: The spiral tooth profile design ensures the continuity of the meshing process, avoiding the impact caused by sudden contact in traditional straight bevel gears, which is particularly suitable for high-speed operation scenarios.
b) High load-bearing capacity: Due to the larger contact area provided by the spiral tooth profile, it can effectively disperse stress, significantly improving the load-bearing capacity and service life of the gears.
c) Efficiency optimization: Through precise processing technology, the friction loss can be significantly reduced, enabling the transmission efficiency to reach over 95%, further enhancing the overall performance of the system.

3) Applications of Spiral Bevel Gear
a) Automotive drive axles (such as the main reduction gears in differentials).
b) Industrial machinery (such as heavy machine tools, mining equipment, etc., in scenarios where high load capacity is required).
c) Aerospace field (such as high-precision transmission systems, in occasions where high stability and reliability are demanded).
