The noise of planetary reducer mainly comes from friction, vibration and collision of transmission gears. How to effectively reduce noise is a very important research direction.

Reducing the noise of planetary reducer gear transmission has become an important research topic in industry. Many scholars at home and abroad regard the change of gear meshing stiffness as the main factor affecting the dynamic load, vibration and noise of gears. In order to reduce noise, the dynamic load and speed fluctuation are minimized by improvement. Practice has proved that this method is effective. However, with this method, molding equipment is required technically, and the vast number of small and medium-sized factories are often unable to implement it.

After years of research, a gear design method is put forward. By optimizing gear parameters such as modification coefficient, tooth height coefficient, pressure angle and center distance, the influence of meshing pitch circle is reduced or avoided, and the meshing impact speed is minimized. The ratio of meshing impact speed to meshing impact speed is within a certain numerical range, which can also significantly reduce the gear noise of planetary reducer.

The above is an introduction to the noise problem of planetary reducer.


  • 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.
