What should I do when the gear reducer has strong vibration

Generally, when we use gear reducer (divided into gear reducer, worm reducer, etc.), its vibration is relatively normal, but if the vibration amplitude is relatively large, we need to pay attention to it. Because this is an abnormal phenomenon, we must not ignore it. What causes the gear reducer to have strong vibration?
A. The fixing screw is loose. Due to long-term operation, the gear reducer (including gear reducer, worm reducer, etc.) may have loose screws and screw damage. These problems may lead to vibration and abnormal working state of the gear reducer.
B. The coupling is damaged. When the coupling connected to the working gear reducer is damaged due to oil leakage, loose screws, etc., it will transmit its increased vibration to the gear reducer, so as to make the vibration of the gear reducer abnormal.
C. The motor screw is loose. Similar to the coupler fault, when the motor vibrates for various reasons, it will also transmit its own vibration to the gear reducer, making the vibration of the gear reducer larger;
D. Bearing wear (a basic type of component failure) is serious. This reason has been explained repeatedly, which will lead to the failure of gear reducer (including gear reducer, worm reducer, etc.);
E. That is, the gear is damaged. The damage of the gear usually has serious tooth surface pitting, increased gear meshing clearance, excessive gear wear (a basic type of component failure) and fracture of the number of teeth. For example, the wear of these gears may cause the gear reducer (including gear reducer, worm reducer, etc.) to work normally due to large vibration; gear reducer
F. The shaft loses balance due to deformation. When the strength and hardness of the shaft cannot meet the requirements or aging due to long-term work, the shaft will deform, and the deformation of the shaft will cause the vibration of gear reducer (including gear reducer, worm reducer, etc.).
2. Prevention and elimination methods
A. Fixing foot bolt (composed of head and screw);
B. Inspect the position and cause of the damage of the coupling, and repair the coupling in time;
C. Tighten the loose screws of the motor;
The above is about the analysis of the causes of strong vibration of gear reducer (divided into gear reducer, worm reducer, etc.) during operation and the corresponding solutions. I hope you can read it carefully.

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.
