WVRBR

Overview
Technical Information
  • 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.
