  • Precision machining ensures smooth engagement with reduced vibration and noise.
  • Excellent fatigue resistance for continuous industrial operation.
  • Precise dimensional and tooth profile control ensures stable equipment performance.

Production Process

  • Premium alloy steel is selected and tested for chemical composition and material properties.
  • Gear blanks are produced through forging, turning, and rough machining processes.
  • Precision hobbing, shaping, and grinding processes are used to produce accurate tooth profiles.
  • Carburizing, quenching, and tempering improve tooth hardness and wear resistance.
  • Final grinding, dimensional inspection, and performance testing ensure product reliability.

Cautions

  • Maintain proper lubrication to reduce wear and extend service life.
  • Operate within the machine’s rated capacity to prevent gear damage.
  • Check backlash, positioning, and meshing accuracy to avoid abnormal noise and wear.
  • Replace the gear promptly if wear, cracks, or abnormal operation are detected.
  • Ensure the gear model, tooth number, module, and rotation direction match the original equipment.
