How do gear manufacturers control the distortion in the heating process of gears

　　Gear is a very important transmission device in mechanical equipment nowadays. As my country's machinery industry has made great progress in recent years, gear has also made very good progress.In fact, there are many uncertain factors in gear processing and production. In order to prevent these factors from affecting the future use of gears, gear manufacturers usually adopt some methods to control them. We will use the following methods to control the gear heating process. Distortion phenomenon as an example to introduce someGear manufacturersHow do you usually control this situation?

　　1. The structure and hardness of the gear blank has a large dispersion after normal normalizing. The use of isothermal normalizing can first improve the uniformity of the structure and hardness, and at the same time reduce the distortion caused by the uneven processing stress.

　　2. The purpose of preheating and step heating heating can make the temperature of the gear's outer and inner parts and various parts more uniform while reducing the temperature difference with the target temperature, and even reduce the temperature difference of each part of the gear.

　　3. High temperature heat treatment such as carburizing after stress relief annealing is not only beneficial to reduce thermal stress, but also beneficial to the release of processing stress and the recovery of twisted lattice.In the process of producing gears, the existing tempering furnace can be used for this operation.

　　For gear manufacturers, the production and processing of gears has always been highly valued.With the increasing application of gear products, the number of gear manufacturers appearing on the market nowadays is also increasing.
