Heavy-duty gears need to be specially designed according to application conditions

Heavy duty gearIt needs to be specially designed according to the application conditions. Why do you say that? Let's listen to the EP editor for you to explain one by one for your reference.

gearIt can be divided into light-duty and heavy-duty gears. There are soft and hard tooth surface products. Common materials include 45, 40Cr, 40CrNi, 20Cr, 20CrMnTi, 30CrMnTiA, 40MnB, etc.After the gear blank is quenched and tempered or normalized, the teeth are cut, then the surface hardening treatment, and finally the finishing processing such as gear grinding. The accuracy can reach 4-5. It is used in high-speed, heavy-duty, compact size and precision machines.

Heavy-duty gears require hard tooth surface design due to the large load on their tooth surfaces.However, due to the wide range of gear industry, product use conditions and requirements are different, production scales are also inconsistent, coupled with factors such as equipment conditions, therefore, different design schemes must be adopted according to the conditions of the enterprise.The strength calculation is necessary when designing high-speed and heavy-duty gears.

Heavy-duty gear processing route (reference):

Cutting-Forging-Normalizing-Cutting Process-Carburizing-Quenching-Low Temperature Tempering-Finishing

The choice of gear material and heat treatment method are determined by the product's stress.Regarding heavy-duty gears, if you have any unclear points or related requirements, you can consult EP for free.
