We all know that gears are prone to deformation during heat treatment, and severe deformation can easily affect our daily work. So how should we prevent gears from deforming after heat treatment?
Prepare organizationally for handling. It should be noted that during normalizing or quenching and tempering treatment, the furnace temperature should be kept uniform, and workstation tools should be used to evenly heat and cool the workpieces. It is strictly prohibited to stack them together. For gears that require drilling to reduce weight, the drilling sequence should be arranged after heat treatment.
The heat treatment of gears adopts high-frequency quenching to reduce the deformation of the tooth surface of the parts; The tooth surface obtained after high-frequency quenching has high strength, hardness, and wear resistance, while the core still maintains sufficient plasticity and toughness. To reduce deformation. High frequency quenching of tooth surfaces should adopt lower quenching temperature and shorter heating time, uniform heating, and slow cooling.
