FAG cylindrical roller bearing performance of the main causes of vibration

In general, FAG bearings of rolling bearing itself does not produce noise. Often feel 'bearing noise' is in fact the cylindrical roller bearing, directly or indirectly, with the surrounding structure vibration sound effects. This is why many times the noise can be seen as involving the vibration problems of the application of the sliding bearing. Due to loading quantity change roller vibration when a radial load loading on a FAG bearing, the number of rolling element bearing load will be a slight change in the operation, i. e. , 2 - 3 - 2 - 3. 。 。 。 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 bearing of the cylindrical roller bearing) 。 The waviness on bearing ring of the self-contained parts or close coordination between the shaft and 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 bearing and the shaft are machined to the required tolerance is very important. Local damage due to the operation or installation errors, a small number of cylindrical roller bearing raceway and rolling element may be damaged. In running, rolled FAG bearing damaged parts will produce a particular vibration frequency. Vibration frequency analysis can identify the damaged bearing parts. The vibration behavior of applications in many applications, the sliding bearing stiffness with the surrounding the stiffness of the same structure. Due to this feature, as long as the correct choice bearing ( Including the preload and clearance) And its application in the configuration, it is possible to reduce the application of vibration. 1. Cylindrical roller bearing diameter of axle and bearing friction compatibility direct contact adhesive to avoid attacks and composition border smooth performance. 2. Clamp into sexual information allows smooth agent foreign pliers and avoid scratch or hard particle ( And) Abrasive wear ability. For metallic materials with low hardness and elastic modulus, clamp in the sex is good, and the nonmetallic materials is not necessarily, carbon graphite, for example, low elastic modulus, but the clamp in the sex is bad. Cylindrical roller bearing usually use soft material and hard material forming friction, ordinary do bearing shell with soft materials. 3. In FAG bearing in the process of the adaptation of the diameter of axle and bearing, reduce the diameter of axle and bearing shell processing error, alignment error, surface roughness parameter values, make contact with an average, thereby reducing the friction and wear rate. 4. Friction compliance data on the surface of sliding friction appearance initial elastic-plastic deformation compensation to match the performance of the poor and shaft deflection. Low modulus of elasticity of material compliance is good. 5. Abrasion resistance into vice materials can resist abrasion. Under the condition of the rules of wear, wear rate or amount of wear, wear the reciprocal of abrasion resistance. 6. The fatigue resistance under cyclic load data can resist fatigue damage. The use of temperature, the strength of the bearing shell material, hardness, resistance to impact strength and organization average opposite tiredness is very important. Running-in, clamp into good data, usually poor fatigue resistance. 7. Corrosion resistant materials can resist corrosion. Smooth oil used in atmosphere will gradually oxidation, produce acidic substances, and in most smooth oil also contains extreme pressure additives, they leave a FAG bearing corrosion data, therefore, sliding bearing information requirements have corrosion resistance. 8. Cavitation resistance motion state, the related to the liquid when the bubble in liquid solid appearance full break, a part of the impact high pressure or high temperature part, will cause cavitation and wear. Data against cavitation and wear can be referred to as cavitation resistance. Usually, copper lead and tin base cylindrical roller bearing alloy and aluminium zinc silicon alloy has good cavitation resistance. 9. The compressive strength of cylindrical roller bearings one-way load without being crushed or size can not change.
