Product Features

  • Product Core: A key transmission gear for driving the planetary carrier system.
  • Core Value: Together with the carrier wheels, it forms a precision planetary gear train and provides the motion source for the specified workpiece trajectory. Its meshing accuracy directly affects transmission smoothness, noise level and service life.
  • Precision Characteristics: Premium alloy steel, such as chromium-molybdenum steel, is processed by precision hobbing, heat treatment, such as quenching or carburizing, and precision grinding to ensure high tooth-surface hardness, excellent wear resistance, accurate tooth geometry and minimal meshing clearance.
  • Customization Advantages: Customized gear rings and sun gears can be supplied with module, tooth count, pressure angle, profile-shift coefficient, internal or external tooth configuration and mounting interfaces matched to the customer's equipment.
