process
Rough machining
Use CNC vertical lathe to rough turn the gear ring blank, process the outer circle, inner hole, and end face, leave machining allowance, lay the foundation for subsequent processes, and roughly mill the tooth shape to remove most of the allowance.
Heat treatment
Perform quenching and tempering treatment, heat to 840-860℃ quenching, and temper at 580-620℃ to give the gear ring good comprehensive mechanical properties and enhance the hardness of the tooth surface and the toughness of the core.
Finishing
Fine turning the outer circle, inner hole, and end face to achieve the dimensional accuracy and surface roughness required by the drawing; use a hobbing machine or a gear shaping machine to fine mill the tooth shape, strictly control the tooth shape and tooth direction errors, and ensure the meshing accuracy; grind or polish the tooth surface to reduce the surface roughness and improve the transmission stability.
