The heat treatment method of DC motor gear

Update:29 Nov 2019

DC motor has several important components, among which gear heat treatment is one of the main components. To prevent gear heat treatment
In normalizing or tempering treatment, it is necessary to keep the temperature uniform, and use the working position apparatus to make the workpiece evenly heated and cooled. Stacking is strictly prohibited
After rough machining, the gear blank is made into precision forging and normalized or tempered to achieve:
(1) soften steel parts for cutting;
(2) eliminate the residual stress;
(3) refine the grain and improve the structure to improve the mechanical properties of the steel;
(4) make organizational preparation for handling.
