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.
