Common TIMKEN bearing vibration analysis of the solution

The waviness in TIMKEN 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. Including mechanical installation tools, induction heater, and hydraulic equipment installation is one of the key stage of TIMKEN bearing life cycle. If not use the right methods and tools to install bearing, so the service life of bearing can shorten. Initial lubrication is also important steps of the installation process. Choose suitable for grease in application of this bearing is the key to the machine best running performance. In addition to the amount of grease and lubrication method can also affect the service life of bearing. Local damage due to the operation or installation errors, a small number of bearing raceway and rolling element may be damaged. In running, rolled TIMKEN 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 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. Including bearings, manual and automatic lubricating device, lubricating grease accessories bearing at run time, the correct lubrication can achieve the best state the performance of the bearing. Choose suitable for grease bearing applications, at the right time interval to use the right amount of grease, is the key to reach the bearing service life of the biggest. In addition, the use of supplements do lubrication method is helpful to optimize the use of the bearing life. Using a single point or multi-point automatic continuous lubrication of lubricator, compared to the manual lubrication method, can provide more continuous, accurate and pollution-free lubrication. In general, TIMKEN bearings of rolling bearing itself does not produce noise. Often feel 'bearing noise' is in fact the bearing directly or indirectly, with the surrounding structure vibration sound effects. This is why many times the noise can be seen as involving the whole bearing vibration problem of application. Due to loading quantity change of vibration roller when a load on a bearing radial load, 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.
