SKF bearing vibration reasons - bearing knowledge

Many users in the use of SKF bearing a lot of problems, in the process of the use of SKF bearing a lot of a lot of problems, general machinery enterprise staff understand the knowledge of the SKF bearing, know how to maintain the bearing, using bearing process matters needing attention are clear, some novice, you don't know how, just know simple looked at the machine run, today we will introduce a SKF bearing will occur in the mechanical vibration phenomenon, this exactly is what reason? 1, the vibration behavior of applications in many applications, SKF bearing stiffness with the surrounding the stiffness of the same structure. Due to this feature, as long as the correct choice SKF bearing ( Including the preload and clearance) And its application in the configuration, it is possible to reduce the application of vibration. 2, SKF bearing parts of the wave degrees between SKF bearing ring and SKF bearing or the shaft under the condition of reamer, SKF bearing ring with adjacent components are likely to match the shape and deformation. If there is a deformation, can produce vibration in the operation. Therefore, the SKF bearing and the shaft are machined to the required tolerance is very important. 3, due to loading quantity change roller vibration when a radial load is loaded in a SKF bearing, the number of rolling element bearing load will be a slight change in the operation, i. e. , this caused the load in the direction of migration. The resulting vibration is inevitable, but can be by axial preload to ease, loading in all rolling body ( Do not apply to the cylindrical roller SKF bearing) 。 4, local damage due to the operation or installation errors, a small number of SKF bearing raceway and rolling element may be damaged. In running, rolled SKF bearing damaged parts will produce a particular vibration frequency. Vibration frequency analysis can identify the damaged SKF bearing parts. SKF bearing vibration small solution: there are three methods can reduce vibration: 1, remove critical excitation vibration from the application; 2, antimicrobial resistance stimulate critical excitation vibration between components and the resonance components; 3, changing the stiffness of structure, so as to change the critical frequency.
