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) Features of Spiral Bevel Gear
a) The helical tooth design increases the contact ratio, resulting in smoother transmission.
b) Optimized tooth surface contact stress distribution extends the service life.
c) 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.
