Optimized Tooth Surface Contact Stress Distribution for Longer Service Life with Spiral Bevel Gears

1) Description of Spiral Bevel Gear

Spiral bevel gears are bevel gears with tooth lines in the shape of a spiral curve,

used for power transmission between intersecting shafts.
2) Feature of Spiral Bevel Gear

• The helical tooth design increases the contact ratio, resulting in smoother transmission.
• Optimized tooth surface contact stress distribution extends the service life.
• They can withstand higher rotational speeds and load capacities.

3) Working Principle of Spiral Bevel Gear

Through the progressive meshing of the spiral tooth profile, impact and vibration are reduced,

enabling continuous power transmission.

4) Application of Spiral Bevel Gear

High-precision machine tools, joint drives of industrial robots.
