Methods of reducing reducer noise

Before and during the use of the reducer, the noise of the reducer will be caused by some reasons. The following causes of noise are summarized:
Causes of noise after assembly and before use:
1. The reducer itself causes noise due to assembly, gear accuracy and meshing. During the assembly of the reducer, the installation error of the gear is large due to the poor coordination between the gear and the shaft and the careless operation of the workers, resulting in noise during work.
2. Gears are produced in batches and using special machine tools and equipment. Low manufacturing accuracy will also cause reducer noise.
Causes of noise generated by reducer during use:
1. During installation, the motor coupling and reducer coupling are not concentric.
2. The frame platform for installing the reducer resonates with the reducer to produce noise.
3. Without good lubrication, the wear of gears and bearings will become more and more serious with the passage of time, resulting in the increase of meshing clearance between gears, the reduction of meshing accuracy and the generation of large noise.
4. After being used for a long time, the bearing breaks due to high load, or the teeth of the gear are knocked off, resulting in noise.
Methods to reduce the noise of reducer:
1. Improve the accuracy of gear and select appropriate gear parameters;
2. Train the assembly workers to improve their assembly level and reduce the installation error of gears;
3. Adjust the concentricity of motor coupling and reducer coupling;
4. Reinforce the rack platform to reduce resonance;
5. Improve the lubrication of gears, reduce the wear between gears and bearings and the meshing clearance between gears;
6. Improve the stiffness of the gear shaft.


  • 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 provide you with a quotation, we will negotiate with you: EXW, FCA, FOB, CIF, CRF, DAP Etc. For mass production, you need to pay 30% of the deposit before production and 70% of the balance before shipment. Our most common way is T/T.
  • 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.
