Which Environments Are Likely To Cause Vibration And Friction Problems Of Cylindrical Roller Bearings

Time:2020.04.17  Source:Roller Bearings Suppliers


Friction vibration mainly refers to abnormal vibration of rolling bearings. Generally speaking, friction vibration easily occurs on large ball bearings, and it is more likely to occur when grease lubrication is used, especially when the lubrication performance of grease is not good. According to experiments and observations, the technical staff of Wuxi Spark Bearing Co., Ltd. found that the generation of frictional vibration of cylindrical roller bearings is often directly related to the properties of lubricating oil. When the lubricating oil performance is not good or not clean, friction vibration is easy to occur, and it is also related to the processing quality of the outer raceway of the cylindrical roller bearing. If a special precision processing method is adopted for this, the friction vibration can be better controlled.


The vibration of the cylindrical roller bearing is basically caused by the vibration of the bearing ring, and is related to the structure, stiffness, manufacturing accuracy, installation conditions and use conditions of the bearing. If there is a large radial ripple on the inner ring raceway of the bearing, the outer ring of the bearing will produce radial vibration when the inner ring rotates. The ripple of the inner ring of the bearing will not only cause the radial vibration of the outer ring, but also cause the axial vibration of the outer ring. When the bearing is subjected to an axial load, the axial relative position of the inner and outer rings of the bearing will change, so When the inner ring rotates, the outer ring of the thrust cylindrical roller bearing produces an axial vibration port. When the vibrating screen is working, for a high-speed rotating bearing, the vibration frequency due to ripples may be equal to the rotation of the shaker shaft Frequency, that is resonance.

Keep the 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, tools and working environment must also be kept clean.


Use carefully when installing

Strong punching is not allowed, and it is not allowed to directly hit the thrust cylindrical roller bearing with a hammer. It is not allowed to transmit pressure through the rolling elements.


Use appropriate and accurate installation tools

Use special tools as much as possible, and try to avoid using things like cloth and short fibers.


Prevent corrosion of bearings

When you directly take the bearing by hand, you must fully wash away the sweat on your hands, and then apply high-quality mineral oil before operating, especially in the rainy season and summer, pay special attention to rust prevention. However, under certain operating conditions, the bearing can achieve a longer life than traditional calculations, especially under light loads. These special operating conditions are when the rolling surfaces (tracks and rolling elements) are effectively separated by a lubricant film and limit the surface damage that can be caused by contaminants. In fact, under ideal conditions, the so-called permanent bearing life is possible.
