Machining challenges
Tooth indexing and profile accuracy require careful control. Heat-treatment distortion, gear-tooth finish and balanced rotation are also key concerns.
Manufacturing route
Blank preparation and pre-heat treatment; rough and semi-finish turning; carbonitriding; datum correction; CNC form grinding; polishing and balancing.
Key control points
Control tooth spacing and profile, locating-feature concentricity, face runout, case depth and hardness. The specified tooth-surface finish is Ra ≤ 0.4 µm.
Dimensional and surface inspection
Inspection covers tooth spacing and profile, surface finish, concentricity and runout, case depth and hardness, magnetic particle testing, balance and mating contact pattern.
The requirements and manufacturing route shown here apply to this project. New components are reviewed against their own drawings and agreed specifications.
