1) Descriptions of Spiral Bevel Gear
Spiral bevel gears are an efficient power transmission component
specifically designed for torque transmission between intersecting
shaft systems. Their unique helical tooth profile structure offers
significant advantages over straight bevel gears, including
smoother operation characteristics, greater load-carrying capacity,
and superior shock resistance performance.
2) Features of Spiral Bevel Gear
a) Outstanding noise reduction and smooth meshing: The progressive
meshing mechanism completely eliminates the impact noise of spur
gears, and is particularly suitable for high-speed and precision
transmission scenarios.
b) Ultra-long service life: The helical tooth surface expands the
effective contact area, achieving uniform stress distribution and
enhancing the fatigue life by more than 40%.
c) High-efficiency Transmission: By adopting advanced processes
such as CNC gear grinding, the friction loss is reduced to less
than 5%, and the transmission efficiency has surpassed the
technical threshold of 95%.
3) Applications of Spiral Bevel Gear
a) Automobile industry
b) Heavy machinery
c) Advanced technology
