ZJY250-15-S-axis mounted gear reducer has abnormal vibration

The main reasons for abnormal vibration of ZJY250-15-S The main reasons for the ZJY250-15-S vibration reduction machine are mechanical failures, improper installation, lubrication problems, etc., as follows:

• Mechanical component failure :

• Gear problem : The gear is prone to wear, pitting, peeling or breaking after running for a long time, which will cause the meshing accuracy to decrease and thus vibration. In addition, the gear manufacturing accuracy is low, installation errors are involved, or the gears are loose, which makes the gap between the gears too large and may cause vibration.

• Bearing problems : Bearings are the key to supporting rotating components. If the bearing is worn, poor lubrication, too large or too small, loose or cracked, the rotation will be unstable, which will cause the reducer to vibrate.

• Imbalance of the rotating components : If the mass distribution of rotating components such as the impeller and shaft of the reducer is uneven, and there is dynamic imbalance or static imbalance, centrifugal force will be generated during rotation, resulting in vibration.

• Deformation of the frame or end cap : After the reducer is running for a long time, important support parts such as the frame and end cap may be deformed, affecting the installation accuracy and operating stability of the components and causing vibration.

• Installation issues :

• Loose anchor bolts : Loose or breaking anchor bolts will cause the reducer to be unstable, easily displaced or overturned, causing violent vibration.

• Poor centering : Inaccurate centering between the reducer and the drive motor or other connected equipment will generate large radial and axial forces, thereby causing vibration and noise.

• Lubrication system problems :

• Insufficient oil : Insufficient lubricating oil will cause poor lubrication, causing dry or semi-dry friction between the transmission parts, inducing vibration and noise.

• Oil contamination and deterioration : Lubricating oil may deteriorate for a long time or be affected by the environment, and may become mixed with impurities or moisture, reducing lubrication and wear resistance, accelerating component wear and causing vibration.

• Improper oil type : If the lubricating oil selected does not meet the requirements of the reducer and cannot provide good lubrication effect, it will increase friction between gears and bearings and other components, causing vibration.

• Load problem : If the load borne by the reducer exceeds its rated load, or there are large fluctuations and imbalances in the load, the operating pressure of the reducer will increase, resulting in abnormal vibration.

• External environment impact : If there are other vibration sources near the reducer, their vibration may be transmitted to the reducer, causing the reducer to vibrate. In addition, the reducer will also be subjected to external impact forces during operation, such as vibrations and impacts of the machine, and will also produce vibrations.

• Electromagnetic force imbalance (if connected to the motor) : If the reducer is connected to the motor, the motor air gap is uneven or the rotor coil is damaged, etc., it may lead to electromagnetic force imbalance, generate an unstable magnetic field, and thus cause the reducer to vibrate.
