Surface treatment process of planetary gear reducer

Choosing a good planetary gear reducer material will help improve its bearing capacity and service life.

    In view of the structural characteristics of the Galaxy reducer and the load characteristics of the gear, hardened gears should be widely used. There are many heat treatment methods to obtain hardened gears. Such as surface quenching, overall quenching, carburizing quenching, nitriding, etc., should be selected according to the characteristics of the gear reducer.


    1. Surface hardening

    Common surface quenching methods include high frequency quenching (for small-size gears) and flame quenching (for large-size gears). When the hardened layer of surface quenching includes the bottom of the tooth root, its effect is good. The tooth surface hardness can reach 45-55HRC.


    2. Nitriding

    Nitriding can ensure that the gear can achieve high tooth surface hardness and wear resistance under the condition of small deformation. After heat treatment, no good finishing is performed, which improves the load-bearing capacity.


    Three, carburizing and quenching

    The carburized hardened gear has a relatively large load-bearing capacity, but the finishing process (tooth grinding) must be used to eliminate heat treatment deformation to ensure accuracy.

    Carburized and hardened gears are commonly used in alloy steels with a carbon fraction of 0.2%-0.3% before carburization. The hardness of the tooth surface is often in the range of 58-62HRC. If it is lower than 57HRC, the hard surface strength will decrease significantly, and it will be brittle if it is higher than 62HR. increase. The hardness of the carburized hardened gear gradually decreases from the surface of the gear to the deep layer, and the effective carburizing depth is specified as the depth from the surface to the hardness of 5.25HRC.

    The effect of carburizing and quenching on the bending fatigue strength of gears not only increases the hardness of the core, but also lies in the residual compressive stress on the surface. It can reduce the stress in the high compressive stress area, so the root part of the tooth cannot be ground during tooth grinding.


FAQ

  • Where is your product mainly exported?

    Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
  • How to provide goods?

    Usually we will ship the goods to the sea. The factory is only 460 kilometers away from the port. It is very convenient and convenient to transport the goods to any other country. Of course, if your cargo is very urgent, Ningbo Airport and Shanghai Airport are also nearby.
  • What is the payment term?

    When we offer you a quote, we will confirm the transaction method with you, FOB, CIF, CNF, etc. For large-scale production, you need to pay a 30% deposit before production and a 70% balance on the copy of the document. The most common way is T/T. Letter of Credit is also acceptable.
  • How to ensure the quality of your products?

    First, we will check after each process. For finished products, according to customer requirements and international standards.
  • How many employees does your company have? What is the relationship between technicians?

    We now have more than 180 employees, including 36 engineers and 28 QCs.
  • What is the ability of your company?

    We have a number of production lines with a monthly production capacity of 1,600 units and an annual production capacity of 20,000 units.
