How to reduce the noise of reducer

The problem of high noise of reducer has always been an inevitable problem of many mechanical equipment. The noise is caused by the operation of mechanical equipment and is inevitable. Therefore, noise has always been a "unsolvable" problem. However, although the noise is inevitable, we can try our best to reduce the noise. Next, the reducer manufacturer will introduce:

For the standard reducer, the manufacturing accuracy of the gear determines its noise value. The main function of reducer gear is to transmit speed and torque. Therefore, the requirements of gear manufacturing accuracy and the stability of its work are the main concerns. Gears with high working stability not only have long service life, but also have much less impact and vibration in transmission, so the noise is less.

In addition, the working stability accuracy of the gear is also required to limit the change of the instantaneous speed ratio of the gear. The error is the rotation angle error that occurs many times per revolution of the gear. It causes the gear to collide and vibrate in the meshing process, resulting in the noise of the gear, which is a high-frequency impact sound. For a gear, the factors that affect the working stability are its base pitch error and its involute profile error.

The motion accuracy of the gear refers to the accuracy of the transmission motion, that is, the maximum error value of the rotation angle error of the gear per revolution cannot exceed a certain limit. Since the motion accuracy of the gear is a large periodic error, the accumulated error of the circumferential pitch within one rotation of the gear due to the radial runout of the gear ring will generate low-frequency noise. However, if the accumulated error of the circumferential pitch increases, the gear meshing impact and angular velocity change will be caused. At this time, the noise will obviously increase and a rumble will be made.


  • 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.
