Cross roller bearings are a common type of bearing that is widely used in everyday life. If you pay attention, it is not difficult to find out that the cross roller bearing works very smoothly under normal conditions. If there is a fault, it will cause shaking or abnormal noise. Now, the Cross-Roller Bearing manufacturer will give you a detailed introduction on the causes and solutions of Cross-Roller Bearing vibration.
1) Causes of Cross-Roller Bearing Shaking
1. Improper installation: The mounting bolts are loose, causing the bearing to shake during operation. If the Cross-Roller Bearing shakes during operation, immediately check all inner and outer ring mounting bolts. Check for looseness and tighten as necessary.
2. Insufficient rigidity of the bearing bracket: The steel structure supporting the Cross-Roller Bearing is not rigid enough, resulting in elastic deformation under load, causing the entire Cross-Roller Bearing to shake.
3. Overload operation: Check if there is overload operation. Overload will also cause the Cross Roller Ring to vibrate. Therefore, the operation must be carried out in strict accordance with regulations.
4. Overload of the bearing structure: Long-term overload operation will cause the raceway to be crushed and the clearance to be excessive. In this case, please notify the Cross Roller Bearing for after-sales adjustment in time to ensure the normal use of the Cross Roller Bearing.
In short, in order to ensure the normal use of the Cross Roller Bearing, if there is a vibration phenomenon in the use process, it is necessary to stop the machine for inspection in time to prevent the long-term vibration from causing greater damage to the Cross Roller Bearing. Next, the editor of Qianxie will introduce how to solve the vibration of the cross roller bearing.
2)、Solution of cross roller bearing vibration
1. Correct installation: There are many types of cross roller bearings, which must be reasonably selected according to different equipment and production requirements, and correctly installed and lubricated according to installation specifications.
2. Regular maintenance: The nuts that are installed and locked are loose, resulting in the unstable fixing of the rotary table bearing, which must be re-locked according to the specified requirements, and the bolt tightening inspection should be carried out regularly, because during the machine operation, with the normal vibration and operation of the machine, the nuts will also loosen slowly, which should be checked regularly.
3. Strengthen the steel structure: If the strength of the steel structure supporting the table bearing is not sufficient, the strength of the steel structure supporting the table bearing should be increased by 14 times to ensure the stability of the table bearing supporting structure and to reduce or eliminate the vibration of the table bearing.
4. Adjust the clearance: Excessive clearance of the Cross Roller Bearing will cause vibration and seriously shorten the service life of the bearing, so it should be adjusted in time. Generally, it should be adjusted by the adjustment end based on the gear engagement and subjected to the light and flexible rotation.
5. Standard use: Do not overload. Observe the nominal working load of the table bearing during operation. Do not overload. This will cause vibrations and damage to the bearing. Always operate in accordance with the equipment regulations.
