In the processing of gears, the heat treatment process is a very important link.The comprehensive performance of the gear that has been processed by the heat treatment process will be significantly improved, but the deformation of the gear during the heat treatment process is unavoidable, and it may even lead to scrap.Therefore, in order to reduce the scrap caused by the heat treatment deformation of the gear and reduce the cost of the production enterprise, it is necessary to take reasonable measures to control the heat treatment deformation.The factors that cause gear deformation during the heat treatment process are complex and diversified. Only by carefully studying and analyzing the influence of these factors can the heat treatment deformation of involute gears be changed.

  The heat treatment process of the gear is the process of changing from the parent phase to the new phase under the action of the phase change driving force.The phase transition temperature is different, the structure transition is different, the structure stress is different.In the heat treatment process, when the structurally weak parts on the progressive gear cannot resist the effect of the residual stress, the gear will locally deform. In addition, the gear surface temperature rises and falls faster than the internal during the heat treatment, and the gradient of the internal and external temperature will cause stress Hierarchical, this will increase the irregularity of gear deformation.

Unreasonable cutting has a certain influence on the heat treatment deformation of gears.Involute gears often have good plasticity after strict pretreatment. If the tooth profile design structure of the involute gears is uniform and symmetric, the uneven stress on the gears during the heat treatment process can be dispersed and the irregularity of gear deformation can be reduced.In addition, the phenomenon of excessive clamping, excessive cutting force or excessive tool friction in the cutting process will increase the residual stress on the gear surface, which will cause the gear to deform during heat treatment.

The nature of the gear material The material of the involute gear is different, and the deformation after heat treatment will be different. Even if the material is the same, the deformation will be different due to the different heat treatment conditions.The nature of the raw material of the involute gear not only affects the service life of the involute gear, but also has unique requirements for the heat treatment process of the gear.It can be seen that the performance of gear raw materials is also an important factor affecting the heat treatment deformation of involute gears.
