What causes excessive vibration of worm gear reducer?

What causes excessive vibration of worm gear reducer?
Worm gear reducer is a power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor (motor) to the required rotation number and obtain a large torque. Among the mechanisms used to transmit power and motion, reducer is widely used.
What are the causes of excessive vibration of worm gear reducer
1. Rotor mechanical unbalance
The imbalance mentioned here refers to the imbalance in the static state of the rotor and the imbalance in the rotating state. The rotor deviates from the axis and deflects and produces abnormal vibration under the action of centrifugal force.
2. Transmission disorder
When the calibration line between the motor and the driver in the worm gear reducer is not good and it is easy to produce vibration, adjust the calibration line and reinstall the connection between the driver and the motor, so as to stabilize the rotation of the motor bearing.
3. Loose rotor parts
Some parts of the motor rotor: commutator, magnetic pole, belt pulley, etc. These looseness will also occur after the reducer has been used for a long time. Generally, in this case, the rotor will have noise. These situations will be handled as soon as possible, because the consequences will become more and more serious after a long time.
4. Large base vibration
In some cases, the excessive vibration of the base also has an impact. The vibration frequency of the base can be said to be the speed of the worm gear reducer. There may be a problem in the design of the base, resulting in an unstable state in operation.
5. Excessive bearing wear
When the bearing works for a long time, the bearing clearance is too large or unbalanced, resulting in bearing friction heating and friction between rotor and stator, which will directly damage the bearing. The sliding bearing is prone to vibration, because it has the viscous effect of lubricating oil, the machine shaft will float, and this can also be related to the bearing weight. If the bearing weight is larger, the wear will be faster.


  • 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.
