We all know that gears are easily deformed during heat treatment, and serious deformations can easily affect our daily work. So how should we prevent gears from deforming after heat treatment?

Make organizational preparations to be able to deal with it. It should be noted that in the normalizing or quenching and tempering process, the furnace temperature must be maintained uniformly, and the work-position equipment must be used to uniformly heat and cool the workpieces, and it is strictly forbidden to stack them together. For gears that need to be drilled to reduce weight, the drilling sequence should be arranged after heat treatment.

The heat treatment of the gear adopts high-frequency quenching of the tooth surface that makes the parts less deformed; the tooth surface obtained after high-frequency quenching has high strength, hardness, and wear resistance, while the core part still maintains sufficient plasticity and toughness. To reduce deformation. Tooth surface induction hardening should adopt lower quenching temperature and shorter heating time, uniform heating and slow cooling.
