INA cylindrical roller bearing vibration failure of the matters needing attention

Small local bearing raceway and rolling element may be damaged. In the operation of local damage due to operation or installation errors. Rolled bearing damaged parts will produce a certain vibration frequency. Vibration frequency analysis can identify the damage of cylindrical roller bearing parts. The vibration behavior of application places 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. INA bearings of rolling bearing itself does not produce noise. In fact usually feel bearing noise is INA bearings, directly or indirectly, with the surrounding structure to produce vibration sound effects. The number of rolling element bearing load will be a slight change in the operation, which is why many times the noise can be seen as involving the whole the vibration problems of the application of cylindrical roller bearing. Due to loading quantity change of vibration roller when a load on a bearing radial load. The resultant vibration is to prevent the axial preload to ease, but can be loaded in all rolling body. Bearing ring with adjacent components are likely to match the shape and deformation. If there is a deformation, the waviness on bearing ring of the self-contained parts or close coordination between the shaft. In the operation of the vibration may be produced. Therefore, the bearing and the shaft are machined to the required tolerance is very important. Contact fatigue failure refers to the INA bearing working surface under the role of alternating stress and failure. Contact fatigue spalling occurred in bearing working surface, often accompanied by fatigue crack, first of all, from the maximum cyclic shear stress under contact surface, and then extended to form a different flake shape, such as dot to pitting corrosion or pitting spalling, peel into small sheet according to the shallow flaking. Refers to the relative sliding friction between the surface abrasion failure lead to constant wear and tear of the working surface of the metal and the failure. Continuous wear will cause bearing parts damaged gradually, and ultimately lead to cylindrical roller bearing size accuracy loss and other related problems. Wear may affect the shape change, the increase of fit clearance and working surface morphology change, may affect the lubricant or make its pollution to a certain degree of lubrication function is lost, so that loss of cylindrical roller bearing rotating accuracy and will not operate properly. Wear failure is one of the common failure modes of all kinds of bearings, according to the wear and tear is usually divided into one of the most common form of abrasive wear and adhesive wear. 1. Inside is rotation is to the cylindrical roller bearing used correctly and the outer orbit when the radial load. 2. Is the inner ring and outer ring relative tilt, the deflection of shaft orbit, orbit, raceway surface on its longitudinal shade, on the load coil outlet has a tilted orbit, double row tapered roller bearing inner ring spinning. 3. Said only bear radial load of outer trajectory. When L said only by the axial load of the track. Inner ring and outer ring tilted relative big bear radial load, only its trajectory deviation in two columns of rail surface 180. The location ( m） 。
