1)Descriptions of Spiral Bevel Gear
As an innovative solution in the field of industrial transmission,
the spiral bevel gear, through its three-dimensional curve tooth
profile design, has perfectly solved the problems of vibration and
wear of traditional bevel gears under high-speed and heavy-load
conditions.
2)Features of Spiral Bevel Gear
a) Acoustic Optimization: Achieves a reduction of 15 dB(A) in sound
pressure level during gear meshing process.
b) Engineering Durability: The tooth profile optimized through
finite element analysis can withstand a continuous load for
20,000 hours.
c) Energy Efficiency Breakthrough: The patented surface treatment
technology enables power loss to be controlled within
4.8% ± 0.2%.
3)Applications of Spiral Bevel Gear
a) Transportation: Electric Drive Axle Assembly for New Energy
Vehicles
b) Energy Equipment: Pitch Control System for Wind Turbines with
Power Output Above 5MW
c) Special Equipment: Cutter Head Drive Unit of Shield Tunneling
