WVRBR

Planet gear carrier and output shaft are integrated structure designed to ensure maximum torsional rigidity.
Planet gear with fll needle design,increase the contact area to improve the rigidity and output torque.
The gears are carburized and quenched to the HRC62 with low carbon steel surface for optimum wear and impact toughness.
Gears refer to foreign imported software-assisted design to obtain the best tooth shape to reduce noise.
Adopt spiral bevel gear design,allow high output torque,more than 30% higher than straight bevel gear.
High allowable input speed,more than 8 times higher than straight bevel gear input.
Spiral bevel gears are meshed by optimum motion error analysis and strict process control to ensure high precision running backlash.
