Friction vibration mainly refers to abnormal vibration of rolling bearings. Generally speaking, large-scale ball bearings are prone to frictional vibration. When grease lubrication is used, especially when the lubrication performance of grease is not excellent, friction vibration is more likely to occur. According to experiments and observations, the technical personnel of Wuxi Spark Bearing Co., Ltd found that the friction vibration of cylindrical roller bearings is usually directly related to the performance of lubricating oil. When the production of the lubricating oil is not useful or clean, frictional vibration is natural to occur, which is also related to the processing quality of the outer ring of the cylindrical roller bearing. If unique precision machining methods are used, the friction and vibration can be better controlled.
The vibration of the bearing ring causes the wave of the cylindrical roller bearing. It is related to the structure, stiffness, manufacturing accuracy, installation conditions, and use conditions of the bearing. If there is a significant radial fluctuation on the inner ring raceway of the bearing, when the inner ring rotates, the outer ring of the bearing will produce radial vibration. The ripple of the inner circle of the bearing will not only cause the radial vibration of the outer ring but also create the axial vibration of the outer ring. When the bearing is subjected to an axial load, the relative axial position of the inner and outer rings of the bearing will change. Therefore, when the inner circle rotates, the outer ring of the thrust cylindrical roller bearing will generate an axial vibration port.
Keep bearings and their surroundings clean.
Even if tiny dust invisible to the naked eye enters the bearing, it will increase the wear, vibration, and noise of the cylindrical roller bearing. Bearings and peripheral accessories should be kept clean, especially dust and dirt, and tools and working environment must also be kept clean.
Please be careful when installing.
Sharp punching is not allowed, and thrust cylindrical roller bearings cannot be directly hit with a hammer. It is not permissible to transmit pressure through rolling elements.
Use the correct and correct installation tools.
Use special tools whenever possible, and avoid using things like fabrics and short fibers.
Prevent bearing corrosion
When holding the bearing directly with your hand, you must thoroughly wash off the sweat on your side, and then use high-quality mineral oil, and then carry out the operation, especially in the rainy season and summer, pay special attention to rust prevention. However, under certain operating conditions, the service life of the bearings is more extended than traditional calculations, especially under light loads. These special operating conditions are: rolling surfaces (tracks and rolling elements) are effectively isolated by the lubricating film and limit surface damage caused by contaminants. In fact, under ideal conditions, the so-called permanent bearing life is possible.
